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. 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 rotatable cutter. The cutter cooperates with a linear cutting edge of an anvil carried by the cutter support to shear 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. The rotatable cutter has a concave groove on one side surface adjacent the outer periphery and a concave groove on the circumferentially extending surface that joins the respective side surfaces. The grooves define a circular cutting edge.
