    • 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.

    • 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.

    • 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.

    • In accordance with the invention, a plate-clamping mechanism is provided for clamping and locking flexible printing plates on a printing cylinder wherein a clamping jaw fitted into a cylinder cavity has a leading edge for clamping one end of printing plate which is (1) non-parallel to the cylinder's axis of rotation and (2) coincident with the periphery of the cylinder when the clamping jaw is in its opened or closed position. In addition, the clamping jaw's axis of rotation is parallel to the jaw's leading edge. Such a clamping jaw eliminates any void between the printing plate and the cylinder surface which might otherwise exist after the plate is tensioned and clamped: such a void is common in printing cylinders with clamping jaws having leading edges non-parallel to the cylinder's axis of rotation.
