ABSTRACT:
An apparatus for cutting lengths of material is provided having a pair of scroll type cams adapted to operate a pair of laterally opposed cutting blades. The apparatus comprises a frame having a front end, a rear end, and generally parallel side members laterally opposed to each other and spaced apart by a plurality of rollers extending generally perpendicular between the parallel side members of the frame. The pair of laterally opposed cutting blades are pivotally connected to the front end of the frame. The blades are constructed from a metallic material, the surfaces of which may be heated electrically to facilitate cutting. The scroll type cams are rotatably mounted to each side of the frame near the ends of the cutting blades and are adapted to engage cam followers connected to the blades. Pneumatically operated cylinders simultaneously rotate each of the scroll cams in the same direction with respect to the frame to convert rotational motion of the cams to linear motion of the cam followers. Rotational movement of the scroll cams together in counterclockwise and clockwise directions is thereby translated into linear movement of the cutting blades toward and away from each other, respectively.
