IMPROVEMENTS RELATING TO TRANSFER MECHANISMS

摘要

A transfer mechanism (56, 60), particularly for use as part of a punching device for punching a plurality of holes in a stack of paper sheets, has drive means (50) which operates to drive the punch assembly (32) into its advanced or its retracted position without significant overrun. A transfer mechanism (56, 60) is present between the drive means (50) and the punch assembly (30) which transmits drive to the punch assembly (30) only between the advanced and retracted positions.
