ABSTRACT:
A cutter apparatus for cutting of rubberized fabric material having high strength material embedded therein, wherein a carriage is reciprocated on a support frame, which frame may be adjusted angularly to provide a 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. The cutter has a plurality of lobes that taper providing a plurality of linear cutting edges. The cutter cooperates with a linear cutting edge on an anvil that also tapers thereby facilitating the shearing of the fabric material. A guide is mounted on the frame over which the fabric material travels and under which a conveyor belt move, which belt transports the fabric material. Upon completion of a 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 a succeeding cutting operation.
