Definitions

  • the guide of the jaw flap games mentioned under claim 4 by chains 31 running on both sides instead of the arm guide is shown in FIG. 5.
  • the puncture and folding knife cylinder 4 carries a chain edge on both sides. The transfer takes place immediately from the folding knife to those running on the circumference of the puncture and folding knife cylinder Folding flap games 11.
  • the product lies on a guide 32.
  • the deflection sprocket 33 is pivoted back and forth in time with the resulting products by a crank mechanism, the sprocket 34 making a corresponding swiveling movement to compensate for the chain length makes.
