Abstract

A cutting mechanism including a backing roller having a longitudinal axis of rotation and a rotatably mounted cutting member having a cutting edge and a longitudinal axis of rotation disposed parallel to the axis of rotation of the roller member. The backing roller is freely rotatably mounted about its axis of rotation. Thus, the cutting member cuts at different locations along the circumferential surface of the backing roller each time. The backing roller is resiliently mounted to float in a direction transverse to a plane extending vertically through its axis of rotation. The roller is mounted on a carrier body that is laterally movable to effect movement of the roller in a direction parallel to the axis of rotation of the roller. Unique timing belt and gear drive mechanisms are used to effect driving of the draw rollers and cutting devices. A particular guide mechanism is used to direct the tear strip from a supply to the point where it is superimposed on a web of wrapping material.
