ABSTRACT:
To insure accuracy in feeding a sheet of paper from an overlapped, shingled paper supply on a make-ready table, a suction pick-up picks up the sheet and moves it upwardly for a limited distance of about 1 mm before initiating the forward movement of the sheet to transfer it to a gripper mechanism of a printing cylinder or transport drum while, simultaneously, moving it transverse to the plane of the sheet to bring it into proper alignment with the drum or cylinder gripper mechanism.
