ABSTRACT:
The holding elements (28), designed as hook-gripper elements (26), are driven in a circulating manner by means of a drive arrangement (44) in a plane at right angles to a stack (16) of printed products that have back margins (20). In the takeover section (46), the cantilever arm (36) of a hook-gripper element (26) comes to bear against the back margin (20) of the topmost printed product (14) of the stack (16). The hook-gripper element is then guided in a sliding manner on the printed product (14) in the direction of a stop, until the hook mouth (38) of the hook-gripper element (26) has seized the back margin (20). From the takeover section up to the transfer of the printed product (14) separated in this way from the stack (16), the direction of movement of the hook-gripper element (26) has a component toward the stop and a component away from the stack (16).
