ABSTRACT:
An apparatus for cutting strip-shaped sewing material on a sewing machine by means of power-operated cutters co-operating in scissor-like manner.
For enabling as well the separation of strips of materials that are hard to cut and for increasing the safely cuttable strip width in general, the invention proposes a cutting apparatus designed in the manner of a "guillotine". The apparatus is characterized by two cutter plates (1, 2) of equal size which are each formed with two cutting edges (1.1, 1.2; 2.1, 2.2) and which are disposed on a support (3) so as to be pressable against each other and at the same time linearly slidable in opposite directions with respect to each other.
