MEANS FOR FEEDING AND CUTTING MEMBRANEOUS SHEET

摘要

A cutting mechanism includes a removably mounted 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 for the roller member. The roller member rotates in a fixed relationship with respect to the cutting member so that the cutting edge operates at substantially the same surface location of the circumferential surface of the backing roller to cut film thereagainst upon each revolution of the cutting member. The roller member is mounted to resiliently float in a direction transverse to a plane extending through the axis of rotation for the cutting member. The drive of the rotating elements is effected through the use of a timing belt operating from the main drive of the machine on which the cutting mechanism is mounted.
