本发明besicht到印刷机（1）具有堆表的片材进给器（3）（2），一个控制的线性致动器的提升装置（5），板桩（4），使得相应的最上面片材在用于分离的工作位置和 输送装置和与分离吸盘（6），观察在片材的输送方向上，有节奏地提起尾随片端部，使得其在所有发动机转速，并在每个片材确保待处理的材料是在分离和输送装置的安全操作，其中，所述Stapelhubes的控制 直接将在抽吸分离器（16），如通过比较电路（15）的装置一个发动机速度的函数的地方。

The invention shall look on a sheet feeder (3) on printing machines (1) with a stacking table (2), of the sheet pile (4) lifting by controlled linear actuator (5), such that the uppermost sheet in the working position for the separation and funding is and with separating suckers (6), as seen in the transport direction of the sheet, lift the trailing sheet end rhythmically, so that it is ensured at all engine speeds and at any sheets to be processed material safe working of the separating and conveying. wherein the control of Stapelhubes takes place directly over the suction separator (16) as a function of the engine speed by means of a comparison circuit (15).
