In a sheet feeder for rotary printing presses having a feed table, a side register lay, and front register lays, a first push type conveyor is positioned in advance of the front lays and a second push type conveyor is positioned between the front lays and the continuously rotating impression cylinder of the printing press. These first and second conveyors cooperate to sequentially grip and convey sheets of paper and the like to the press's impression cylinder which is equipped with register lays and grippers. The feed table's front register lays are arranged to lift the first registered sheet thus permitting a succeeding sheet to advance beneath the raised sheet. |
