ABSTRACT:
A device for a pick-up unit for an infeed station of a processing machine which includes a carriage mounted in a main frame for shifting both laterally and vertically. The carriage is provided with a bar carrying several suction cups and is shifted laterally by a rack gear on the carriage being engaged by a pinion from a drive motor which rotates in response to the sensed lateral position of the sheet being lifted. The device is preferably used for centering sheets being picked up from a stack or pile of sheets within a feed station of a machine designed for converting or processing these sheets.
