PERFORATOR WITH TRANSLATING PERFORATING DEVICES

摘要

Apparatus for perforating a moving receiver includes perforating devices, each with two parallel perforating wheels and a pressure wheel arranged so that the perforating wheels are pressed laterally against the pressure wheel to define two perforating areas and a chad area arranged laterally between the perforating areas. A drive mechanism rotates the perforating or pressure wheels to perforate the moving receiver parallel to its feed direction in the perforating areas, whereby one or more proto-chads are defined on the receiver. A transport mechanism selectively moves the plurality of perforating devices perpendicular to the feed direction of the receiver. A controller receives a job specification including two or more specified perforation locations and causes the transport mechanism to laterally position two or more of the plurality of perforating devices to perforate the moving receiver in the specified perforation locations.
