Abstract: An arrangement for longitudinally oscillating a doctor blade relative to the form cylinder in a printing press. The arrangement includes a double armed rocker having one arm coupled to the doctor blade and the other arm coupled to a hydraulic cylinder. The rocker is mounted on a central eccentric portion of a pivot shaft through a one way idler bearing and the pivot shaft is rotatably supported in a counteracting one way idler bearing. By oscillating the rocker, through sequential operation of the double acting cylinder, the pivot axis of the rocker is continuously displaced, causing the points of reversal of doctor blade movement to be continuously varied independently of the press operation, while maintaining a uniform stroke. In the illustrated embodiment, a pneumatic control is provided for controlling operation of the hydraulic cylinder, and thus the rocker arm and doctor blade movement.

Abstract: An impression cylinder for a rotogravure press having a recessed sheet stock gripper mechanism with a swivelling mechanism that swivels the grippers within the cylinder contour by revolving the grippers around a theoretical axis on the cylinder contour. The swivelling is rigidly and precisely constrained along an arcuate path by a plurality of arcuate guides disposed along the axial length of the cylinder. The opening and closing of the grippers and the swivelling of the grippers into the cylinder contour are caused to occur in sequence synchronized to the cylinder rotation by cam followers on gripper shaft pivot arms cooperating with cam followers journaled to the gripper shaft that are spring pressed onto cam surfaces fixed to the machine frame at the ends of the cylinder.

Abstract: A washing assembly for a lithographic press including a washing roller having a porous resilient surface for carrying a charge of cleaning fluid, the washing roller being mounted in a frame for rocking movement from a disengaged position to a first washing position in which the washing roller is engaged with the surface of the blanket cylinder and a second washing position in which the roller is engaged with the surface of the impression cylinder. A drive wheel is provided at the end of the blanket cylinder for coupling to a driven wheel at the end of the washing roller as the frame is rocked to its first washing position for differential driving of the washing roller to produce relative wiping against the surface of the blanket cylinder. A squeeze roller in pressing engagement with the washing roller prepares the surface of the washing roller to accept a fresh charge of cleaning fluid. In the preferred embodiment as used in a "five cylinder" press, first and second washing rollers are journaled on different portions of the same frame so that in the first washing position of the frame the washing rollers respectively engage the surfaces of separate blanket cylinders. The gap in the impression cylinder is spanned by a bridge to prevent the washing roller from falling into the gap.

Abstract: An auxiliary drive for the ductor roller of a sheet-fed offset press continues to advance the ductor roller in small angular steps during press stoppages. The damping unit drive which continues to run during press stoppages drives the ductor roller stepwise by way of an eccentric drive linkage and a ratchet wheel disposed on the ductor roller journal. When the press is running, a rocker lever in the drive linkage can be pivoted away from the throw zone of the eccentric for example, by a piston actuated by oil pressure of the press's oil supply system. In alternative embodiments, the lever arm can be pivoted away by a compressed air cylinder or a suction cylinder which become operative when the press is running.

Abstract: A clamping device for thin flexible printing plates has a tensioning rail at the trailing wall of a wide longitudinal groove in the plate cylinder. The tensioning unit is mounted for axial and peripheral adjustment on a support of "L" cross-section having a first leg seated with respect to the bottom of the groove and a second leg presenting an upstanding reference surface interposed between the tensioning rail and the trailing wall of the groove. A set of tensioning springs recessed in the tensioning rail bear against the reference surface and apply peripheral tension to the plate. A spring detent latches the tensioning rail temporarily against the reference surface, overcoming the tensioning springs while the trailing edge of the plate is being gripped. The spring detent is mounted upon and movable with the support. Screws having a plurality of selectable holes anchor the support in a series of peripheral positions for accommodation of plates of different length. A plurality of jack screws threaded into the tensioning rail have tips which bear against the reference surface on the support for removing slack from the plate and for tensioning of the plate about the surface of the cylinder.

Abstract: A device for the lateral and longitudinal positioning of sheets on the feed table of a printing press, with the leading edge of the sheet engaging a set of front stops and the lateral edge of the sheet in contact with a side guide, enabling accurate registered pick up by a transfer cylinder or the like. Cooperating laterally swingable wiper members are provided both above and below the sheet having friction shoes for wiping the sheet in the direction of the side guide. The friction shoes are connected to the respective wiper members in such a way as to provide freedom of relative movement at right angles to the direction of wipe so that the sheet may move against the front stops at the same time that is being wiped toward the side guide. In the preferred embodiment of the invention the wiper members are in the form of synchronously rotated arms timed so that the arms engage the sheet as the sheet approaches the front stops, and the friction shoes are in the form of rollers interposed at the ends of the arms, freely rotatable about axes which extend in the direction of wiping movement, so that the sheet may complete its movement against the front stops, with accommodating rotation of the rollers, as it is being urged by the rollers toward the side guide. In an alternative embodiment the friction shoes are stiffly secured to the wiping members in the wiping direction but supported with light resilient force in the direction of movement of the sheet so as to permit final movement of the sheet simultaneously in the two directions.
