A method for forming an auxiliary stack when a sheet stack is changed in a sheet delivery of a sheet-processing machine includes providing an auxiliary stack support for supporting the auxiliary stack during a non-stop stack change and multiple stop and separator elements disposed outside a stacking area in front of edges of the sheet stack to form a gap in a stream of sheets conveyed by a conveying system and released to fall onto the sheet stack. The sheet stack is lowered to form a gap for the auxiliary stack support, the stop elements for the front edge and the rear edge of the sheet stack are moved into a disengaged stand-by position before the main stack is lowered. For this purpose, the stop elements are equipped with remote-controllable actuating devices that are connected to a control unit. A device for forming an auxiliary stack is also provided.

Method and device for forming an auxiliary stack

A method and a device combine auxiliary and main stacks in a delivery or feeder of a machine for processing printing materials. The device includes a rake that can be moved in and out between the main and auxiliary stacks by a motor drive. A control computer controls the motor drive of the rake. Different speed profiles are stored in the control computer for the drive of the rake as a function of the printing materials in the stacks. A sheet-fed offset printing press having the device is also provided.
