ABSTRACT:
A web engagement system for an off-reel printing press comprising a guide piece, a guide channel and drive stations for the displacement of the guide piece. The guide channel accommodates and guides the guide piece and is located on the frame of the press between the drive stations. The guide piece is slightly longer than the distance separating the various drive stations. The advance of the guide piece is caused as a result of the displacement of a slide equipped with wedging rollers which alternately grip and release the guide piece. A pair of wedging rollers prevents the return movement of the guide piece. The invention is used for introducing paper webs unwinding continuously in an off-reel printing press.
