  • Cutting device for paper and foil webs, particularly for printers, plotters, copiers and similar machines
    Patent number: 4665787
    Abstract: 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..sub.max) corresponding to the maximum admissible cutting angle between cutting wheel (40) and cutting rail (50). Depending on the force (F.sub.F) of a spring (46), the cutting resistance (F.sub.W), 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..sub.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).
