Abstract
A rotary printing press has a folding station where the printed web is perforated both transversely and longitudinally in order to expedite subsequent folding thereof into signatures. In order to incorporate a longitudinal perforator into the folding station without adding to its size, a longitudinally perforating blade similar to a circular saw is mounted to a blade carrier shaft which is rotatably supported opposite a feed roller by which the web is frictionally fed into and through the folding station. An annular, longitudinally grooved anvil is formed circumferentially on the feed roller for engaging the longitudinally perforating blade via the web being thereby perforated. The longitudinally perforating blade is movable with the blade carrier shaft into and out of perforating engagement with the anvil on the feed roller.
