Abstract
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 cut. A cutter support is mounted on the carriage for movement therewith but relative pivotal adjustment thereto about a vertical axis. 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. A spring on the other end of the shaft biases the cutters into shearing engagement with an anvil on a cutter guide over which the fabric material is to travel. The cutting action of the cutters is a shearing action as the cutter and carriage are reciprocated across the support frame. The cutter guide supports the anvil during its cooperative cutting action and such anvil is selectively interconnected to one of two lever means to facilitate the cuts in the direction of translational movement of the cutter to prevent interference with the material to be cut. Lever means may be provided to pivot the anvil out of the way to permit the indexing of the material and the return of the cutter and anvil during such indexing. A further modification provides means for moving the support, cutter means, and anvil up above the guide means to permit the indexing of the material to be cut as the cutter means is returned to its initial starting position.
