A protective device for a printing machine cylinder assures a risk-free flying changeover of printing plates. The protective device includes a rotatable ring that supports a sleeve-shaped cover. The sleeve-shaped cover can be positioned to partially envelop or cover the cylinder at a separation of the cylinder from another cylinder or a roller in the printing machine.

A pair of synchronously rotating draw-in devices are placed in contact with an outer layer of a web of material wrapped on a supply roll. The outer layer is pulled between the two draw-in devices. This pulled-in outer layer can them be conveyed to a separate processing station where it can be given a fresh end.

A material web guide assembly for a rotary printing press having at least one shiftable web guide roller utilizes fixed and movable guide assemblies to provide a web guide path for guiding a web being threaded through the press. The movable guide assembly is shiftable with the shiftable web guide roller. Cooperating guide channels on the fixed and movable guide assemblies cooperate with each other to lengthen or shorten the guide path in concert with movement of the shiftable web guide roller.
