Click here for a printable version of this file

SECTION I - CLASS DEFINITION

Class 242 includes and is limited to:

(A) A process or apparatus for progressively winding elongated flexible material more than 360° about an axis of a take-up of restricted length, as in: (l) Unwinding and rewinding an information-bearing carrier associated with a nominal work station such as that found in a magnetic recorder/player, film projector, or camera; (2) Forming an indefinite length of running material in loops to form a bundle of coils solely by wrapping or winding the material about a form (i.e., exclusive of the use of a die or other shaping device); (3) Unidirectional winding and unwinding (i.e., simultaneously winding and unwinding material while turning in a single direction); (4) Reeling (i.e., repetitively winding and unwinding the same material); and (5) Winding by use of machine or implement for: (a) permanently winding material directly onto a core having distinct ends to create a composite article exclusively by winding; (b) winding material, usually strand, in a helical or random manner to form a storage coil for subsequent unwinding; or (c) winding material, usually web, in a convolute manner to form a storage coil for subsequent unwinding;

(B) A storage coil formed exclusively by such a winding process or apparatus;

(C) A process or apparatus limited to unwinding material from a storage coil;

(D) A process or apparatus for tensioning (i.e., applying or regulating longitudinal stress in a running material of indeterminate or indefinite length);

(E) A process or apparatus for guiding (i.e., establishing or confining the path of movement of a running material of indeterminate or indefinite length); or

(F) A subcombination peculiar to winding, unwinding, tensioning, or guiding, such as a spool, spindle, mandrel, or dispenser.

SECTION II - NOTES TO THE CLASS DEFINITION

(1) Note. A process is placed with the apparatus for its practice.

(2) Note. Class 242 provides for a "coil holder" whose structural significance is generally concentric to a coil axis to support wound material and includes a spool, spindle, mandrel, dispenser, or container with a specific coil support. There is a natural similarity between a coil holder, reeling device, winding machine, and unwinding machine. For example, a support rack from which a stock material coil is unwound, even with a rewinding handle to rewind surplus material, should be placed with coil holder because of primary, overall similarity of structure and function. Similarly, a coil support for dispensing material by simply pulling on a free material end is placed with coil holder unless the coil support includes additional significant unwinding structure expressly provided for as an unwinding machine. Examples of such additional structure provided for as an unwinding machine are means for attachment of a material to a preceding material, a mobile unwinding station, supply replenishment structure, reserve coil storage, a material end separator, a detector, indicator, or control, a drive, an unwinding limit, or a specific unwinding guide/guard.

(3) Note. Class 242 does not provide for a process or apparatus for: (a) Winding onto articles of indefinite length, such as a hose conductor or other elongated member without distinct ends; (b) Winding of a line having a detachable load except when placement or storage of the line in a coiled state clearly establishes a precedent to Class 242 as in the case of: (1) a fishing reel, seatbelt reel, or similar reeling device, and (2) a component of a reeling device such as a drum, material distributing guide, etc.; (c) Unwinding combined with cutting, tearing, perforating, etc.

(4) Note. A tensioner or guide claimed in terms of a composition of material or treatment with no significant tensioner or guide structure will be classified with the appropriate material or material treatment class.

(5) Note. FIgure eight winding on a support is considered winding proper for Class 242 if it forms at least one complete cycle or figure eight on the support.

SECTION III - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

STRUCTURE OF CLASS 242

See References to the Current Class, below, for a list of related subclass groups of Class 242.

Subclasses 118 - 159, 163 through 178, and 222 have not been screened for hierarchical priority within Class 242, and should be carefully reviewed to assure a complete search of the prior art particularly with a search relating to: (a) unidirectional winding and unwinding, (b) tension control or brake, (c) unwinding machine, (d) coil holder, or (e) guide.

LINES BETWEEN CLASSES 83, 225, AND 242

Class 83 and related Class 225 take unwinding and cutting, severing or breaking, whereas Class 242 takes a similar operation accompanied by winding.

LINE BETWEEN CLASS 182 AND CLASS 254

Reeling devices in Class 182 are generally of the type provided for in a Class 254 hoist because they accept a load.

LINE BETWEEN CLASS 206 AND CLASS 242

A coiled material enclosed in a box or covering sheath can be provided for in Class 206 (e.g., subclasses 389+), if the disclosure indicates that either: (a) the coil is separated from the receptacle or package for winding or unwinding, or (b) the sheath about the coil is punctured to permit unwinding. However, Class 242, subclasses 588+ would be more appropriate if either: (a) the material is unwound from the coil while in the receptacle, or (b) if a formed unwinding aperture indicates a capacity for use of the package contents without destroying the package. Note particularly Class 206, subclasses 53 through 55, 225 through 227, 389+, and 574.

LINE BETWEEN CLASS 211 AND CLASS 242

See Class 211, Supports: Racks, particularly subclasses: (a) 1.52+ for a power-operated article support adapted to be repositioned relative to a loading station, which article support may be analogous to a coil or core so positioned in Class 242, subclasses 533+ and 558+; (b) 44 for a rack for a bolt or card of wound material that may be removed for unwinding; and (c) 119.15 for a line tightener that may be analogous to Class 242, subclasses 388.2+ for a similarly functioning structure.

LINE BETWEEN CLASS 224 AND CLASS 242

See Class 224, Package and Article Carriers, subclass 162 for a support constructed to be borne by a living being which is particularly analogous to Class 242, subclass 404.1.

LINE BETWEEN CLASS 226 AND CLASS 242

See Class 226, Advancing Material of Indeterminate Length, which may include a nominal recitation of a supply or take-up coil (e.g., less than a support for such a coil or a cooperative relationship between a tension or exhaust detector and reel driving or reel stopping means, etc.), subclasses 168+ for orbitally traveling material-engaging surface(s), subclass 195 for means to retard material movement or subclass 196.1 for a passive guide combined with a material feeder. Class 242 currently provides for a "strand tensioning device" in subclasses 147+, a "strand guide" in subclasses 157+, a "tension control or brake" in subclasses 410+, and a "material guide or guard" in subclasses 615+ which conflict with Class 226 subclasses 168+ and 195. Plans are underway to resolve this conflict by making Class 242 subclasses 157+, 410+, and 615+ the residual location for their respective features, with Class 226 subclasses 168+ and 195+ being limited to their respective features combined with a material feeder. This has already been resolved for Class 226 subclass 196.1.

LINE BETWEEN CLASS 360 AND CLASS 242

Class 360 provides for claimed information erasure prevention means (other than a nominally recited pin or filler), details of a single recording element (e.g., a multitrack transducing head), means to extract a loop of tape from the cartridge and transfer the loop about a named transducer head, a plurality of elements peculiar to a recorder (e.g., alternately engageable record and erase heads), or structure peculiar to a recorder completely remote from winding, tensioning, or guiding (e.g., signal volume control). Search Class 242 for unwinding/rewinding drives, and subcombinations such as cartridge/cassette structure and related perfecting feature; e.g., position retainers, brakes, brake release devices, door structures, pinch rollers, guide components, cartridge/cassette housing construction and material having a specific composition, hardness, thermal property, electrical property, antistatic property, etc., particularly subclasses 324+ for unwinding and rewinding an information convertible carrier and 335+ for guiding, unwinding, or rewinding a carrier stored in a cartridge/cassette.

15,	Brushing, Scrubbing, and General Cleaning,   for a winding, unwinding, or reeling device combined with a specified brush or other cleaning device designed to clean material as it is wound or unwound (e.g., subclasses 256.5+ and digest 13).
19,	Textiles: Fiber Preparation,   coreless winding of a group of textile fibers prior to the formation of the fibers into a twisted strand, in contrast with Class 242, which provides for winding such a fiber around a spindle or spool. Particularly note subclasses: (a) 149 for depositing a specific sliver (strand of loose, untwisted fibers) onto an article or facsimile article, and (b) 159 for depositing a specified sliver into an open can.
24,	Buckles, Buttons, Clasps, etc.,   for a specified clasp combined with a coiled tethering line in subclasses 3+ (e.g., a tethered pen), and subclasses 115+ for a fixture for holding cord or rope.
26,	Textiles: Cloth Finishing,   subclasses 71+ for cloth finishing that may include a guide structure.
28,	Textiles: Manufacturing,   for textile operations that may include or be analogous to winding, tensioning, or guiding, particularly subclasses: (a) 141 for a specific textile fabric splicer; (b) 176 for winding or unwinding a warp thread sheet (group of parallel threads); (c) 194 for tensioning combined with warp preparation or handling; and (d) 195 for traversing (distributing) combined with warp preparation.
29,	Metal Working,   which may combine winding, tensioning, or guiding of elongated flexible material with additional manufacturing such as shaping or assembly, particularly subclasses: (a) 25.41+ for making a condenser that may include winding or unwinding; (b) subclass 452 for prestressing or tensioning a static or running filament or strand in a manufacturing operation; (c) subclasses 596, 598, 605, and 618 for making an electrical device that includes a manufacturing operation in addition to winding; (d) subclasses 732+ for motor/generator winding apparatus combined with additional manufacturing apparatus; (e) subclass 780 for assembly of parts to running length of a workpiece by orbital member, which may include wrapping; (f) subclass 806 for assembly apparatus for a film or tape cartridge; and (g) subclass 894 for a process for making a wheellike element, which may be analogous to formation of a spool or winding drum.
30,	Cutlery,   subclass 127 for a twine guide combined with a specified cutter.
33,	Geometrical Instruments,   for instruments that may include reeling apparatus as a component of a specifically claimed geometrical instrument such as a measuring tape. Class 242 provides for a nominal recitation of elongated geometrical instruments such as a tape, line, or typical display. Note particularly subclasses 393 , 413+, 713+, 754, and 761+ for a reeling device combined with a specific straight edge cord (chalk line) or flexible distance measuring element (e.g., measuring tape).
34,	Drying and Gas or Vapor Contact With Solids,   subclasses 117 , 118, and 153, which may include a reeling device or guide for handling strand or web subjected to a specified Class 34 art process or apparatus.
38,	Textiles: Ironing or Smoothing,   particularly subclass 102.21 for a winding device using supply and take-up spools between which cloth is stretched (e.g., to smooth fabric quilting).
40,	Card, Picture, or Sign Exhibiting,   particularly subclasses 116 , 117, 347, 348, 385+, 470+, 483, 514+, 518+, and 529 for an unwinding/rewinding or reeling device combined with a specific register, file, or changing exhibitor. Specifying either a detail of the exhibited medium, or a structure to display or project the medium (e.g., light source, mirror, etc.), justifies placement in Class 40; however, a specified intended use will not bar placement in Class 242. Subclasses 341+ for a copyholder where the copy is advanced relative to a static guide by manual force applied directly to the copy, or to guide or advance material relative to a viewing locus; or an indicator (e.g., line guide or pointer) relative to the copy and a support therefor.
43,	Fishing, Trapping, and Vermin Destroying,   for a process and apparatus particularly designed for capturing fish that may involve a winding or guiding device as a component, particularly subclasses: (a) 8, for net handling apparatus; (b) 20, 21, 25, 26.1, 42.28+, and 57.3, for a reeling device combined with specified apparatus useful in capturing fish (e.g., an angling rod, "downrigger", or "trotline" hook holder); and (c) 24, for a line guide mounted on a specified angling rod. Placement in Class 43 generally requires that the winding, tensioning, or guiding device be specifically limited to fishing, trapping, etc. For example, a "downrigger" (trolling depth device) can be properly considered a reeling apparatus with a guide boom to position the line until line-carried equipment, a boat mounting, bait positioning, measuring, or sampling equipment is specified in a claim.
52,	Static Structures (e.g., Buildings),   particularly subclass 108 for a device for unwinding strand, web, or connected sections specified as a building component material. However, Class 242 can accept either: (a) winding or unwinding material used in preliminary fabrication of a building component where the material is defined as a typical elongated material, or (b) prestressing a pipe or vessel by simply wrapping a tensioned cable around a body to reinforce same.
53,	Package Making,   particularly subclasses 430 and 118+ for winding package contents, and subclasses 409, 587, 588, and 203+ for forming or covering a package that may include winding.
57,	Textiles: Spinning, Twisting, and Twining,   particularly subclasses: (a) 58.67+, 71, 78, 92, 98, 99, 303, 305, and 313 for a helical winding/unwinding device that additionally provides a twisting or related function, and (b) 3 through 18 for wrapping elongated material onto an indefinite-length core by equipment and/or a process similar to lathe-type winding of a short article found in Class 242. The fundamental distinction between Class 57 and Class 242 in covering or winding articles is that Class 57 provides for winding an article (core) of indefinite length or any length with twisting, whereas Class 242 winding is limited to an article or core of definite (relatively short) length (i.e., with distinct, spaced ends).
65,	Glass Manufacturing,   subclass 10.1 for winding combined with a specified glass-making operation or subclasses 182.1+ for a fluid support means for an article or preform.
66,	Textiles: Knitting,   particularly subclasses 126 , 130, 146, 151, and 158 for a strand control device (e.g., a guide or tensioner), in a specified knitting process or apparatus.
68,	Textiles: Fluid Treating Apparatus,   subclass 198 for a hollow coil holder associated with fluid treatment means.
72,	Metal Deforming,   appropriate subclasses, particularly 135+, 146+, 183, 288, and 289 for coiling elongated metallic material that additionally bends the metal beyond its elastic limit. With respect to winding, Class 242 and Class 72 contain patents where a material being worked is disclosed as being held to a mandrel or core and wound thereon due to the interaction of (a) a force rotating the core and (b) a force restraining the material to movement along a course substantially tangential to the surface of the core or the wound product. A patent disclosing such a force applied to metal and claiming use of a deflector closely adjacent to the core will be placed originally in Class 72 unless the specification clearly teaches that the metal is not deformed beyond its elastic limit. Patents disclosing such forces applied to metal, wherein the restraining force is claimed as means, remote from the core for retarding movement of the work (tensioning) will be placed originally in Class 242 unless the disclosure positively stresses deformation of the metal. With respect to unwinding, a patent wherein metal is unwound from a coil will be placed originally in Class 72 only if a claimed disclosure positively teaches deformation or stress beyond the elastic limit, as by the use of a deflector or tensioning means.
74,	Machine Element or Mechanism,   particularly subclasses: (a) 22+ for mechanical movements of general application that may be appropriate to or a subcombination of a winding/unwinding machine or reeling device (e.g., for distributing material being wound); (b) 543+ for a general purpose handle; and (c) 575+ for a pawl and ratchet device of general use. Generally, Class 74 provides for a generic gearing arrangement or mechanical movement subcombination that can include a component of a winding or reeling device, such as a means to index a core or guide of a winding or reeling device so long as the actual winding output is not specifically required. However, an exception exists for handles and one-way devices expressly provided for in Class 242.
76,	Metal Tools and Implements, Making,   subclass 81.4 for a spring-biased strop retractor in a specified tool/implement making machine or process.
82,	Turning,   particularly subclass 169 for an expandable mandrel for a turning lathe that may grip a workpiece in a manner similar to a winding machine supporting a take-up mandrel.
83,	Cutting,   particularly subclasses 78+ , 102+, 302, 426+, 909, 920+, 937, 949, and 950 for cutting material unwound from a coiled supply as well as cutting in general. (See Lines to Other Classes and Within This Class for the lines between Classes 83, 225, and 242.)
84,	Music,   particularly subclasses 122+ , 132, 133, and 150 for a winding/unwinding device combined with specific music technology (e.g., particular sheet structure or tracking board).
87,	Textiles: Braiding, Netting, and Lace Making,   subclasses 31 and 59 for a winding device or tensioning means combined with specific Class 87 technology.
100,	Presses,   particularly subclasses 12 , 13+, 76, and 79 for a specified press that may include either: (a) applying a binder or covering subject to be wrapped, tensioned, or guided, or (b) utilizing a binder or cover from a supply that can be coiled.
101,	Printing,   for convolute winding or unwinding combined with structure peculiar to printing (e.g., a printer head or antismut device).
111,	Planting,   subclasses 44 and 45 for a reeling device used with a special line adapted to actuate a planting drill seeder at selected intervals.
112,	Sewing,   for winding, tensioning, or guiding combined with a specified sewing process or apparatus; particularly subclasses 136+ for a work manipulating guide, subclasses 254+ for thread tensioning, subclasses 261 for a guard, subclasses 279 for bobbin winding, or subclasses 302 for a thread guiding or handling means.
114,	Ships,   subclass 254 for a line storage reel for a towing cable in ship structure.
116,	Signals and Indicators,   particularly subclass 305 for a specific alarm or indicator without specified detail of a winding, unwinding, tensioning, or guiding structure.
118,	Coating Apparatus,   subclass 33 for tensioning, and subclasses 229 and 235 for winding/unwinding combined with a specified coating means.
119,	Animal Husbandry,   subclasses 794 and 796 for a reeling device for a specific animal tethering line, collar, harness, or the like.
137,	Fluid Handling,   particularly subclasses 355.16+ for a hose reel combined with a specified connection between a fluid supply and a hose.
138,	Pipes and Tubular Conduits,   appropriate subclasses for details of pipe structure that may bear upon a winding method or apparatus by which the pipe was made.
139,	Textiles: Weaving,   for a cloth-weaving process or apparatus, particularly subclasses: (a) 200, 201, and 212+ for a tension-regulating means to control the weft (filling or transverse yarn of a woven fabric, and (b) 304+ for a fabric take-up that may include winding.
140,	Wireworking,   for a process or apparatus for operating on wire usually involving by disclosure bending the wire beyond its elastic limit, particularly subclasses 71.5 , 92.1, 92.2, and 124 for winding material, usually wire, disclosed as being wound on an intermediate form for subsequent removal as a convolution or bundle of convolutions to form an article (e.g., stator, armature, or light filament). However, when winding into a storage coil from which the wire is to be subsequently unwound it is necessary that a claim specify that the wire is bent beyond its elastic limit or subject to some other wireworking action.
144,	Woodworking,   subclass 14 for apparatus for making a spool from wood or similar material, and subclass 268 for a coiling former for wood bending.
156,	Adhesive Bonding and Miscellaneous Chemical Manufacture,   for: (a) winding an article such as a ball or pipe claimed in combination with the use of a bonding agent, and (b) bonding the ends of material together to provide a continuous material that may be used in a winding or unwinding process in general. However, Class 242 provides for: (a) winding similar articles even those disclosed with bonding so long as the bonding is unclaimed, and (b) joining ends of unwinding material together including joining by bonding when such joining is claimed in combination with manipulation of an expiring or fresh supply coil. Note particularly, subclasses: (a) 51+ for a process of covering an electrical conductor; (b) subclasses 143+ for a process of helically winding and bonding a wire to reinforce a flexible tube; (c) subclasses 169+ for a process of winding and bonding a stressed web into a laminae; (d) subclasses 180+ for a process of winding and bonding a filamentary material to form an article; (e) subclasses 184+ for a process of winding and bonding a web or sheet; (f) subclasses 405.1+ for apparatus for bonding combined with feeding; (g) subclass 422 for apparatus for winding tire bead; (h) subclasses 425+ for apparatus for progressive helical winding material combined with bonding; (i) subclasses 443+ for winding or wrapping apparatus used to wind and bond material to articles (e.g., balls); and (j) subclasses 504+ for apparatus for end-to-end splicing of web materials.
160,	Flexible or Portable Closure, Partition, or Panel,   particularly subclasses 55 , 120+, 170+, and 238+, especially subclasses 252, 263, 266, 307, 309, 313+, 319+, and 383+ for winding and unwinding to position specified retractable closure structure or related panels.
162,	Paper Making and Fiber Liberation,   subclasses 118+ and 283+ for a process using interfelted fibers in a liquid suspension to form a web wound or wrapped upon itself.
178,	Telegraphy,   subclass 42 for guide or feeding structure combined with a specified recorder or printer of a telegraph system.
180,	Motor Vehicles,   subclass 7.5 for a vehicle-mounted towing winch, and subclasses 268+ for a reeling device for a seatbelt or harness combined with a controller that is a component of a motor vehicle (e.g., an ignition switch).
182,	Fire Escape, Ladder, or Scaffold,   particularly subclasses 73+ , 231+, and 237 for a reeling device for positioning a specified body harness or supple escape device (e.g., a rope ladder), for use as a fire escape frequently combined with an unwinding control or brake. (See Lines With Other Classes and Within This Class for the line between Class 182 and Class 254.)
185,	Motors: Spring, Weight, and Animal Powered,   subclasses 27+ for a weight motor and subclasses 37+ for a spring motor as a subcombination or of general use.
187,	Elevator, Industrial Lift Truck, or Stationary Lift for Vehicle,   subclasses 254+ for a winding or traction drum in combination with elevator structure.
188,	Brakes,   for details of a brake, per se, or in generalized combinations, particularly subclasses 65.1+ for a brake specifically adapted to completely halt the movement of a strand, and 82.1+ for a one-way brake.
191,	Electricity: Transmission to Vehicles,   subclasses 12+ and 91 for a reeling device combined with a windable conductor and means providing electrical connection through the conductor to a vehicle.
192,	Clutches and Power-Stop Control,   for a detail of a power-stop, clutch-brake combination, or clutch, per se, or in general use.
198,	Conveyors: Power-Driven,   subclasses 813+ for an endless belt conveyor tensioner.
200,	Electricity: Circuit Makers and Breakers,   particularly subclasses: (a) 61.13+ for a specific switch designed for operation in response to a condition in either a running length of material or a spool or guide associated with the material, and (b) 61.58 for a switch designed to be associated with a seatbelt.
206,	Special Receptacle or Package,   particularly subclasses 387.1+ and 389+ for a packaged coil of wound material in which the disclosure indicates that winding, or more frequently unwinding, occurs with either: (a) the coil disassociated from a particular receptacle or package (e.g., box, storage tube, bag, or binder), or (b) a cover, wrapper, band, or other packaging material where a pay-out aperture seal is destroyed (irreversibly modified) as a prerequisite to winding or unwinding. A coiled material enclosed in a box or covering sheath can be provided for in Class 206 (e.g., subclasses 389+), if the disclosure indicates that either: (a) the coil is separated from the receptacle or package for winding or unwinding, or (b) the sheath about the coil is punctured to permit unwinding. (See Lines With Other Classes and Within This Class for discussion of the line between Class 206 and Class 242.)
211,	Supports: Racks,   particularly subclasses: (a) 1.52+ for a power-operated article support adapted to be repositioned relative to a loading station; (b) 44 for a rack for a bolt or card of wound material that may be removed for unwinding; and (c) 119.15 for a line tightener. See Lines With Other Classes and Within This Class for a discussion of the line between Class 211 and Class 242.
220,	Receptacles,   for a receptacle detail that may be analogous to a tape or film cartridge provided for in Class 242.
223,	Apparel Apparatus,   subclasses 106+ for a stand, rack, or other holder particularly designed to hold a sewing accessory that may include a thread spool.
224,	Package and Article Carriers,   subclass 162 for a support constructed to be borne by a living being. See Lines With Other Classes and Within This Class, for the line between Class 224 and Class 242.
225,	Severing by Tearing or Breaking,   for unwinding with subsequent severing, Class 225 severing being limited to tearing or breaking. Class 242 provides the reverse, namely, severing with subsequent winding. Note particularly subclasses 10 , 23+, 34+, 51, 53, 56+, 63+, 76, 88, and 106 of Class 225.

(1) Note. An endless convolutely wound coil whose material is fed axially subjects each of the convolutions to move longitudinally requiring each convolution to move at a greater angular velocity than the adjacent outer convolution. Patents provided for here reduce the friction caused by the convolutions rubbing against each other by a tendency to drive each convolution or groups of convolutions at appropriately different speeds.

(1) Note. One or more (but not all) of the elements may be stationary. There must be a relative rotation between the elements of at least 360 degrees. A support consisting of two rotatable elements having slightly spaced axes of rotation and having equal numbers of axially extending bars that interdigitate do not rotate significantly relative to each other, but substantially only translate relative to each other and, therefore, is not placed in this subclass.

364.12	Shifting material axially:
	This subclass is indented under subclass 364.11.  Subject matter in which the material wound on the support is moved axially on and relative to the support during operation. (1) Note. The material need not slide on the surface of one of the rotary supports to meet the requirements of this definition. The material may be acted upon between rotary supports to cause it to engage the next support at a location axially spaced from the last one. (2) Note. For placement in this subclass, there must be structure specifically designed to shift the material. Forcing of wound material axially by mere engagement with newly introduced material is not sufficient in absence of structure to force the new material axially. SEE OR SEARCH THIS CLASS, SUBCLASS: 366.2, for axial material shifting means having general application to unidirectional winding and unwinding devices.

	This subclass is indented under subclass 364.  Subject matter in which number of turns or loops of material on the support is caused or permitted to vary during operation, i.e., the rates of winding and unwinding onto the support may be unequal. (1) Note. For placement in this subclass, a patent must recite an element, such as a flyer that places material onto the material support or a guide that removes material over an end of the support, that enables material to be supplied to or removed from the support at a rate independent of the rate at which it is removed or supplied. SEE OR SEARCH CLASS: 139,  Textiles: Weaving,   for weaving apparatus having unidirectional winding devices for storing a variable number of turns of yarn for supplying weft yarn at high speed to the weaving apparatus.

(1) Note. The manner of removal of material is such that the material may be removed even if the support were not rotating.

365.2	Single material strand simultaneously wound into or unwound from plural coils:
	This subclass is indented under subclass 364.9.  Subject matter in which a single continuous piece of material is wound onto and unwound from plural distinct coils the same time. (1) Note. The coils may or may not be located on the same support.

365.6	Fixed number of windings on winding surface (e.g., positive feeder):
	This subclass is indented under subclass 364.  Subject matter constructed so that the number of turns of material on the support cannot vary during normal operation. (1) Note. For placement in this subclass there must be structure or corresponding method steps present for maintaining the material in a path on the support such that there is no substantial change in the number of turns on the support. The structure may be a guide. The recitation of a positive material feeder with disclosure of a guide for maintaining the material path is sufficient to warrant placement of the original in this subclass. (2) Note. Changes in the number of turns of material on the support during the initial introduction of material onto the support or on removal of material (e.g., after depletion of a material supply) are disregarded. SEE OR SEARCH CLASS: 66,  Textiles: Knitting,   for positive yarn feed devices in knitting machines.

366.2	Shifting material axially on support:
	This subclass is indented under subclass 364.  Subject matter in which the material wound on the support is moved axially relative to the support during operation while remaining on the support. (1) Note. Changing the winding point (where the material being wound meets the support or body of wound material) is a different operation than the one provided for in this subclass. See the search notes below. (2) Note. For placement in this subclass, there must be structure specifically designed to shift the material. Forcing of wound material axially by mere engagement with newly introduced material is not sufficient in absence of structure to force the new material axially. SEE OR SEARCH THIS CLASS, SUBCLASS: 366.3, for a unidirectional winding and unwinding device in which the winding point is systematically changed during winding, (i.e., the material is traversed on the support). 365, for a unidirectional winding and unwinding device having a rotatable support onto which the number of turns of material wound is variable during operation in which material on the support is shifted along the support.

(1) Note. This subclass takes documents directed to the structure of controls for operating or the drive train for driving a material support (e.g., winding drum) or other material winding mechanism (e.g., orbital winding flyer). The mere recitation of a motor, drive means, or control means is not sufficient to warrant placement here. Sensor details alone are sufficient only when not provided for above. See the search notes below. SEE OR SEARCH THIS CLASS, SUBCLASS: 364.7, for a sensor forming part of a winding drive control system in a unidirectional winding and unwinding device. 366.2, for a unidirectional winding and unwinding device including a drive for a drum constructed to shift material axially during operation.

The terms reeling device or reel are used here to denote a device typically including a frame, a spool, and a drive mechanism to cause elongated material to be alternately wound and unwound, not to be confused with reel commonly used to denote the material holder or spool, per se. (2) Note. An inclusive exception is made for a disclosure of: (a) a particular spool provided with a distinct hand grip that replaces a distinct frame; (b) a frame-supported, stationary spool on which the same material is to be hand wrapped replacing the typical drive mechanism; or (c) a drive mechanism mounted on a frame for winding and unwinding a material in which the inner convolution (e.g., a metal tape) serves in lieu of a distinct spool. (3) Note. Excluded from this section is a coil holder to which a previously wound coil is introduced for dispensing even though a manual drive may be provided with a drive mechanism such as a crank to rewind a temporary excess of dispensed material.

(1) Note. This subclass and the subclasses indented hereunder provide for winding a product of manufacture in which the elongated material is wound on and, by disclosure, remains as a distinct coil in intimate contact with a core so long as the core remains with the winding apparatus.

Guidelines for placement of an original patent directed to a winder or winding method with features appropriate to production of either an article or storage package and certain subcombinations within Class 242 is as follows: (a) a winder or subcombination appropriate to winding a storage package as well as an article can be properly placed as a storage package winder, which generally provides a more comprehensive breakdown, if the specific article is unclaimed and winding a storage package is considered to be a clear alternative (e.g., a winder distributing wire in layers on a core useful as a storage coil as well as an inductance coil); (b) a claimed work holder, material tensioner, guide or guard, or a frame subcombination, is properly placed with the appropriate article winder if the subcombination is peculiar to a provided article winder (i.e., not readily used for a package winder and not having general utility). Some examples proper for article winders are: (i) a tensioner for stressing a pipe, vessel, or other core rather than stressing the material for proper winding; and (ii) a holder, guide, or guard asymmetrically related to the coil to be wound in a manner invariably related to winding a slotted article, such as a ring or spheroid.

(1) Note. Material distribution is achieved by relatively shifting either or both the material supply (e.g., a guide) and the take-up member during winding to vary the point of winding along the take-up member. By this shifting, the winding point on the take-up member can be repeatedly traversed in opposite, back and forth directions, typically in a reciprocating or oscillating motion parallel to the winding axis. A high ratio of traverse relative to rotation creates widely spaced convolutions useful in axial unwinding (e.g., for a weaving shuttle), whereas a low traverse/rotation rate is useful to create adjacent convolutions (e.g., for high volume, compact material storage).
