  • the invention relates to a stack cutting device with a first stack positioning device according to the preamble of claim 1 and a method for cutting a stack of sheets by means of a stack cutting device.
  • Stack cutting devices are used in particular to cut stacks of sheets into stacks of blanks.
  • Such stacks of benefits are, for example, stacks of securities, in particular stacks of banknotes.
  • stacks of benefits can also be stacks of labels or business cards.
  • Devices are known by means of which the respective stack of sheets is first trimmed at its edges and then cut into, in particular, strip-shaped intermediate stacks, which are then in turn cut into stacks of blanks.
  • a stack cutting device which has a stack support surface and a rotary stamp which can be pivoted about a vertical pivot axis in order to pivot a stack of sheets, the rotary stamp additionally being horizontally movable by means of a horizontal drive in order to move the stack of sheets horizontally.
  • Sheets that lie as flat as possible on top of each other can be wavy.
  • the lower sheets are flattened by layers above them. This makes it possible for sheets that are further up to be wavier than those that are further down. Arches that are more wavy have a smaller extent in the horizontal direction. If the edge of the entire stack is now cut off, less material may be cut off from the top sheets than from the bottom sheets.

  • a stack cutting device which has an upper press plate on which an upper rotary punch is mounted in a spring-loaded manner.
  • the rotary punch can be lowered onto the stack individually or together with the press plate.
  • a tong loading station is arranged.
  • a stack cutting device which has an upper and a lower rotary die which are movable together in a horizontal direction for moving a clamped stack of sheets in a horizontal direction.
  • a stack cutting device is known in which stacks are moved on a circular path to different knives without their orientation being changed.
