<p>A device for positioning printing material for use in a printing apparatus in which printing is applied to the printing material by passing the same through between an impression cylinder (6) and a blanket cylinder (5), the device comprising positioning member (14) disposed in an recessed portion formed on an outer surface of the impression cylinder (6), the positioning member including, a stopper (30) with which a leading end of the printing material (26) comes to contact, drive means (40) for moving the stopper forward and backward in a direction of transport of the printing material (26), control unit (51) for controllably driving the drive means (40) while the impression cylinder (6) is being rotated, and operation means (52) for operating the control means (51). Accordingly, displacement of superimposed printed images in a direction of transport of the printing material resulting from the fact that the positioning member improperly positions printing material can be corrected rapidly and accurately. <IMAGE></p> |
