US Patent 7217051 Slitter module with optional cutter

A slitting mechanism has one or more slitting shafts between rotating brackets. Each shaft has one or more slitting disks arranged along its length. Each disk has a cutting edge and the slitting mechanism can either enter or not enter a path followed by a web of media such as wallpaper media, according to a requirement of an operator. An optional transverse cutter for the mechanism is disclosed. The mechanism and the cutter extend across a chassis with end plates. The end plates are separated enough to allow a web of media to pass between them. The end plates support a motorised cutting blade. The blade is supported at each end to perform a cutting stroke which begins on one side of the web and finished on an opposite side of the web.
