Patent ID: 7997575

Claim:
A device for depositing sheets for a printing machine, comprising: a support for a sheet to define a path of rotation of the sheet; first and second coaxial, drivable sheet transport elements that can be rotated about their joint axis independently of each other, each for grasping a leading edge of a sheet and depositing the sheet on a stack after the sheet has traveled through the path of rotation, so that one of the transport elements is ready to receive or grasp the next sheet when another of the transport elements is still occupied with transporting or depositing a previous sheet; each transport element including: at least one radially outward extending free end; at least one overlap element to overlap the received leading edge of the sheet in such manner that the leading edge of the sheet can be grasped between said overlap element and said support, wherein the rotation of the transport element causes a region of rotation of the corresponding overlap element to be defined; and a pivotable drag element attached to the free end of the corresponding transport element for pulling a sheet that has been deposited on the stack toward a mechanical stop after the sheet is released by the overlap element, each drag element pivoting between an inoperative position within the region of rotation of the corresponding overlap element and an operative position in which it is pivoted at least partially out of the region of rotation of the corresponding overlap element in order to perform its dragging function.
