AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT:
Claims 1-20 are cancelled.
1. A method for making a composite material for use in a musical instrument, comprising:
providing a pultrusion apparatus comprising a source of a plurality of fibers, a resin bath containing a resin, a curing and forming die, a puller, and a cutter,
loading said pultrusion apparatus by guiding said plurality of fibers through said resin bath to coat said fibers with said resin to provide a plurality of resin-coated fibers,
guiding said plurality of resin-coated fibers through said curing and forming die to form said plurality of resin-coated fibers into a continuous bar of containing said plurality of said resin-coated fibers,
guiding said continuous bar of plurality of said resin-coated fibers into said puller, said puller arranged to pull said continuous bar of said resin-coated fibers, and said fibers before being coated in said resin bath, through resin bath containing said resin, and through said curing and forming die, so that said continuous bar of resin-coated fibers leaves said puller,
using said cutter to cut said continuous bar of resin-coated fibers, after it leaves said puller, into predetermined lengths to form tonebars for a musical instrument,
whereby when said pultrusion apparatus is loaded and then activated, said continuous bar of resin-coated fibers will be drawn by said puller from said curing and forming die and said resin-coated fibers will be drawn from said resin bath, and said fibers will be drawn from said fiber source so that continuous bar of resin-coated fibers can be cut by said cutter into said tonebars.
