Signature perforating device

摘要

A signature perforating device includes a perforating cylinder and a cooperating counter perforating cylinder. The perforating cylinder carries a perforating blade strip which is formed by a number of perforating blade elements. These elements are held in place on the perforating cylinder in a profiled blade holding strip. Individual ones of these perforating blade elements can be removed from the strip for replacement without disruption to adjacent blade elements.
