ABSTRACT:
In an apparatus such as a printing press or collator for performing operations such as printing, perforating, punching, die cutting, and the like on a continuous paper web, a registration unit for changing the phase of a first shaft relative to a second shaft where said shafts are rotatably mounted between parallel frame members of the apparatus, the registration unit having a sleeve rotatably mounted about the second shaft with a concentric output gear mounted thereto and rotatable therewith. An output drive gear is mounted to the sleeve and concentric with the output gear for rotation therewith, said output gear providing the output drive for rotatably driving said first shaft. A motor drive and gear assembly is mounted to said second shaft outboard of said frame for rotation therewith and is in engagement with said output drive gear for selectively rotating said output drive gear relative to said second shaft, whereby rotation of said output drive gear relative to said second shaft produces rotation of said sleeve, output gear, and first shaft relative to said second shaft. In one aspect of the invention said sleeve is rotatably mounted about said second shaft outboard of the frame members and said output gear is also outboard of said frame members. In another aspect of the invention, said sleeve extends through one of said frame members, and said output gear is located inboard of said frame members.
