Abstract: Apparatus (10) for repeatedly severing rubber and plastic material (T) at selected locations along a length thereof including a frame (15), an arbor (41) mounted on the frame carrying a knife blade (50) for rotation in a circular path, a guide for supporting the material to be severed in the path of rotation of the knife blade, a rotary actuator (56) for selectively intermittently driving the arbor for instituting rotation of the knife blade, and a cylinder assembly (90) for supplementing the driving of the arbor and for braking the arbor to a stop after the knife blade has severed the material.

Abstract: Apparatus (10) for repeatedly cutting extruded rubber and plastic material (M) at preselected locations along a length thereof including, a frame (11), a drive shaft (35) mounted on the frame, a drive member (25) effecting a selected speed of rotation of the drive shaft, feed rolls (110) intermittently driven by the drive shaft for controllably advancing the extruded material, and a cutting element (B) reciprocally driven by the drive shaft for repeatedly cutting the extruded material advanced by the feed rolls at the preselected locations.
