Abstract

Device for cyclically lifting and lowering at least one lifting sucker in a feeder of a sheet-processing machine, wherein a sheet lifted by the lifting sucker is transferred to at least one pull sucker for further transport, the lifting sucker being operatively connected by a lifting-sucker transmission to a cyclically controlled drive, the lifting-sucker transmission including a coupler having a joint steplessly bringable onto various cam paths in accordance with a selective suction position of the lifting sucker, all of the cam paths having a common intersecting point.
