Abstract
In a device for the synchronized introduction of sheets into a treatment machine, e.g. a printer-slotter or cutter for processing corrugated cardboard sheets, in which a reciprocating pusher pushes forward the lowermost sheet of a stack in a magazine between two stops and into engagement with feed rollers, the stack rests on the upper run of a set of endless belts, which upper run extends over a suction box which is maintained continuously under suction during forward movement of the pusher, the belts are driven forwardly to facilitate movement of the lowermost sheet from the bottom of the stack, and belts being immobile during the return movement of the pusher.
