An apparatus for individually conveying printed products arriving in an imbricated product stream, comprising a number of driven controlled grippers revolving and guided in a closed path of travel for engaging the leading edge of the printed products. The gripper drive contains means for temporarily restraining the grippers. The gripper drive has at least one continuously driven sluice for the cycled recall of the restrained or stopped grippers. Operatively associated with the sluice is an endless revolving conveyor element equipped with entrainment members engaging the trailing edge of the products, the entrainment members being provided at a uniform spacing at the conveyor element. The conveyor element, as concerns the entrainment members, is driven in cycle with the sluice and opposite in sense to the sense of rotation or revolution of the grippers. There is also provided an infeed device having a drive operatively coupled with the drive of the sluice by a synchronous control. |
