ABSTRACT:
Bias cutting of rubberized fabric material wherein a carriage is reciprocated on a support frame, which frame may be adjusted angularly to determine the bias angle of cut. A cutter support is mounted on the carriage for movement therewith. Such cutter support journals for rotation a shaft that supports on one end a rotating cutter with a plurality of circumferentially spaced linear cutting edges that cooperate with an anvil carried by the cutter support to shear the fabric material. A guide is located adjacent to the anvil over which the fabric material is to travel and under which the conveyor belt moves. Upon completion of the cut, the cutter, anvil and its supporting framework is pivoted out of the way to permit the indexing of the material and the return of the cutter and anvil during such indexing to the starting position in preparation for the succeeding cutting operation.
