The invention relates to a controllable gripper unit (4) for sheet feeders in printing machines for the retarded deposition of sheets, which unit is distinguished according to the invention by the fact that the grippers (7) are located on a slide (18) which executes a relative movement in an opposite direction to the running direction of the transport chain (1), which movement is controllable via a cam roller (27) and cams (28). In this way, retardation of the grippers is achieved while the speed of the transport chain remains constant. …<IMAGE>… |
