ABSTRACT:
A suction lifter in a feeder of a sheet processing machine is cyclically reciprocated for separating and picking up sheets from a sheet pile and transferring them to a towing sucker. A suction lifter drive is operatively connected to the suction lifter and the suction height, i.e. the spacing between the lifter and the top sheet on the sheet pile, may be adjusted with the suction lifter drive. The drive is a control cylinder which rotates around a cylinder axis and which is axially shiftable along the axis for the purpose of adjusting the suction height of the suction lifter.
