Definitions

  • the invention relates to a delivery system for flat printed products, in particular on a sheet delivery of rotary printing machines.
  • auxiliary stack carrier can be inserted between two sheets in the conveying direction of the sheets, the incoming sheets being temporarily picked up on an auxiliary stack.
  • Suitable means are provided for storing the auxiliary stack on a new main stack carrier after the main stack change.
  • the auxiliary stack carrier has a small layer thickness and remains under the auxiliary stack, so that it acts as a base when it is deposited on the selected main stack carrier.
  • Such an auxiliary stack carrier can either be cut from a web roll or removed individually from an interchangeable cassette.
  • DE 44 05 586 C1 discloses a device for the exact separation of an auxiliary stack or a main stack in a non-stop delivery in a sheet-fed printing press.
  • Carrier and a cross stack are articulated vertically by means of coupling links on a crossbar attached to the sheet brake.
  • Lower stops and wedges are arranged on the carrier in the direction of the stack, on the side of the carrier facing away from the stack there is arranged in parallel a coupling rod which can be actuated by a working cylinder and which actuates the rear arch support via ternary members.
  • DE 42 17 816 C2 discloses a device for the continuous delivery of flat printed products, in which a separating belt is provided which serves to separate the stacks into the main and auxiliary stacks.
  • This separating belt comprises a widened separating edge which can be moved into the stacking area transversely to the paper running direction.
