Mechanism for drawing superimposed webs for rotary press

摘要

A mechanism for drawing superimposed webs in a rotary press comprises: a drag roller provided between a printing press and a folding machine so as to be rotated and driven at a peripheral velocity suitably higher than that of a plate cylinder; a plurality of propeller rollers operative for selective engagement with or disengagement from the edge portions at the respective sides of a plurality of printing webs which are superimposed upon each another and wound around the outer peripheral surface of the drag roller, the propeller rollers being rotatable and provided along the outer peripheral surface of the drag roller at both ends thereof; and pressing apparatus for pressing the propeller rollers onto the edge portions of the printing webs. The plurality of printing webs fed from the printing press, superimposed upon each another and wound around the outer peripheral surface of the drag roller, are respectively pressed along their edge portions at opposite sides thereof onto the outer peripheral surface of the drag roller by the plurality of propeller rollers and are simultaneously drawn by rotating and driving the drag roller, to be supplied to the folding machine.
