ABSTRACT:
A paper perforating assembly which is designed for use in micro-perforating. The assembly includes a micro-perf cutter blade which is attached to a rotatable shaft of a perforating machine. The assembly also includes a cutting ring assembly attached to a second rotatable shaft of the machine. The cutting ring is preferably backed by a soft biasing member carried in a channel of the ring assembly and allows the ring to float which compensates for concentricity problems during perforating.
