Method of introducing an auxiliary pile carrier

Method of introducing an auxiliary sheet pile carrier above a main sheet pile to be removed, the introduction being effected during uninterrupted feeding of additional sheets above the main sheet pile in a sheet travel direction and in synchronism with the travel of a sheet to be deposited, which comprises:

• controlling respective drives at a sheet delivery by a control device which determines actual data of a printing press, so that the auxiliary pile carrier traverses a velocity profile identical with a velocity profile of the sheet to be deposited in order to avoid relative movement between the auxiliary pile carrier and the sheet to be deposited;
• and
• jointly delaying the sheet to be deposited and the auxiliary pile carrier closely before an end of the main pile facing away from the printing press.

• and
• determining with the control device actual data of the printing press including press speed, press angle and sheet format.

• and
• reconciling a position of a gripper opening cam, via a drive assigned thereto, with a drive of a sheet brake, and an acceleration profile thereof by comparison with an acceleration profile stored in a memory of the control device.
