Cutting device for paper and foil webs, particularly for printers, plotters, copiers and similar machines

摘要

The cutting wheel (40) is rotatably guided in a cutting carrier (50), and under the force of a spring acting axially against the cutting rail (50) so that the cutting wheel (40) is pivotable out of a neutral starting position plane parallel to the cutting rail (50), by an angle ( alpha max) corresponding to the maximum admissible cutting angle between cutting wheel (40) and cutting rail (50). Depending on the force (FF) of a spring (46), the cutting resistance (FW), and the frictional force between cutting wheel (40) and cutting rail (50), the cutting wheel (40) adjusts itself automatically to the respective cutting angle ( alpha s). The pivoting range for the cutting wheel (40) extends in both directions, so that the cutting device acts in both directions of movement of the cutting carrier (26).
