Abstract: A printing press for use in printing a continuous paper web having a fountain section and a plate section each pivotally mounted to a main frame. The fountain section includes a removable ink fountain and rotatably mounted fountain and transfer rolls, and the plate section includes a rotatably mounted plate cylinder. An impression cylinder is rotatably mounted in the main frame. The fountain section is pivotal for selective engagement and separation of the transfer roll with the plate cylinder, and the plate section is pivotal for selective engagement and separation of the plate cylinder with the transfer roll and the web supporting impression cylinder. The pivotal sections are actuated by hydro-pneumatic cylinders and are adjusted against mechanical stops which maintain the adjustment of the contacts between the respective cylinders and rolls. The fountain section also has adjustment and mechanical stop devices for selectively engaging and separating the fountain roll with the transfer roll.

Abstract: A diecutting apparatus is disclosed which accepts interchangeable die cylinders of a variety of lengths and diameters. Rapid replacement, adjustment and reversal of the die is possible. The station has a support bar for mounting the die cylinder and a slidable support for the die cylinder bearing blocks. The bearing blocks slide horizontally along the support bar to accept die cylinders of a variety of lengths. The support bar is mounted at each end on transverse slides which slide vertically to accept die cylinders of a variety of diameters. Mounted above the die cylinder support bar is a support slide on which are mounted contact rollers and pressure cylinders for applying a biasing force to the die cylinder. The slides may be fixed in place for each particular die cylinder used. The pressure cylinders and contact rollers act on bearing surfaces on the die cylinder.

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.

Abstract: In an apparatus such as a printing press or collator for performing operations such as printing, perforating, punching, die cutting, crimping and the like on a continuous paper web, a registration unit for particular use in a crimping and tractor station and for changing the phase index of a shaft relative to the web where said shaft is rotatably mounted between parallel frame members of said crimping and tractor station or unit, the registration unit having a sleeve rotatably mounted about the shaft with a sleeve gear drive mounted thereto and rotatable therewith. A second gear drive member is mounted to the sleeve and concentric with the sleeve gear drive for rotation therewith, said sleeve gear drive providing a drive means for rotatably driving said shaft.
