ABSTRACT:
A cutter assembly for severing pieces from a length of material and advanced into proximity thereto includes a driven anvil roll and a driven rotary cutter roll disposed in opposed relation with each whereby the length of material is advanced between the rolls for cutting. The cutter roll carries at least one knife blade on its periphery to cut the material against the anvil roll into predetermined lengths as it is advanced between the rolls. The at least one knife of the cutter roll is mounted at an angle with respect to the longitudinal axis of the cutter roll so as to engage the material in a shearing motion and the cutter roll is attached to the anvil roll and mounted so as to be movable away from the anvil roll against the force of resilient means as the knife contacts the anvil roll during rotation. The degree of such movement may be adjusted by the use of shims removably placed between the resilient means and the mounting point of the cutter roll. A method of establishing the desired spacing includes measuring the distance between the centerlines of the rolls and utilizing shims therebetween to adjust the gap.
