Abstract
Abstract 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.
