  • the pulleys 52, 53 are circulated by a belt 54 (FIG. 12).
  • the belt 54 is in turn driven by a pulley 55 (FIG. 2) which is rotated by a pair of bevel gears 56 through the shaft 28, so that upon actuation of the drive motor 32, the support rods 19, the side stop 30 and the hold down 36 synchronously adjusted become.
  • the ratio between the drive of the drive chains 20, 21 and the drive of the blank holder 36 is selected so that the blank holder 36 is always substantially in the middle between the longitudinal center of the frame 12 and the side stop 30.
  • a paper end stop unit 58 or 59 is arranged above the paper support unit 17 or the paper support unit 18.
  • the structure of the Textilendantschrittikien 58 and 59 will be described below with reference to the Textilendanschlagiser 58, which is located above the paper support unit 17.
  • the paper end stop unit 58 has two sprockets 60, 61 arranged transversely to the paper feed direction PL at a distance from the paper support plane, which are surrounded by a transport chain 62.
  • stop elements 64 are arranged at a distance corresponding to the distance of the gaps between the support rods 19, the stop surface extends perpendicular to the chain plane. This is achieved in that the pitch of the drive chains 20, 21 of the support rods and the pitch of the drive chain 62 for the stop elements is the same.
  • the paper feed facing angle between the axes of rotation of the sprockets 60, 61 and the support plane AE is in a stop position of the Textilendanschlagmaschine 58 approximately 70 °.
  • the distance of the Textilendanschlagiser 58 to the support plane AE is selected so that the stop elements 64, which are located on the paper inlet facing strand of the transport chain 62, touch the support plane AE or cut them, so that in the cross-break module 10 incoming paper to these stop elements 64 can strike.
  • the paper inlet facing stop elements 64 are each arranged between two adjacent support rods 19 and the outermost support rod 19 and the side stop 30.
  • the transport chain 62 is moved synchronously with the drive chain 20 to prevent mutual collision of the support rods 19 and the stopper members 64. In the position shown in Fig.
  • the transport chain 62 is driven by a spindle drive 66.
