    • An ink roller for a printing press having a cylindrical outer shell presenting a roller surface and having a control fluid-displacing core, a hollow cylindrical partition being interposed between the shell and the core to define inner and outer annular passageways connected in series having respective inlet and outlet openings. A source of cooling fluid is connected to the inlet opening so that a feed stream of cooling fluid flows longitudinally through the inner passage and turns around to form a cooling stream flowing in counterflow relation through the outer passage. The cylindrical partition is formed of conductive material so that heat absorbed at a given region of the roller surface by the cooling stream flows radially inwardly for absorption by the feed stream at substantially the same rate, so that the cooling stream has only minimum net gain or loss of heat; this tends to equalize the temperature along the length of the cooling stream and hence along the length of the roller surface. In the preferred embodiment of the invention the thermal conductivity of the cylindrical partition in the radial direction is so varied as a function of length that the rate of heat transfer radially through the partition from the cooling stream to the feed stream over each unit of length of the partition is substantially equal.

    • A sheet feed drum for transferring sheets in a rotary printing press wherein the drum other contour is provided with an ink-repellent coating and two circumferentially spaced front and rear drum edges defining a duct therebetween which accommodates a sheet gripper system. The ink-repellent coating supporting a netting-like fabric relatively loosely thereon prevents any smearing of a freshly printed underside of a sheet during sheet feed on the drum while the sheet is engaged by the gripper system. Starting at the front edge of the drum, the outer contour of the drum is constructed in the form of a continuously increasing signal merging into a fixed drum radius whereby the netting-like fabric is contactable by the freshly printed underside of the sheet on the sprial first substantially flatly behind the front edge of the drum and then in any subsequent angle of rotation of the drum without the sheet tangent ever being bent or creased.

    • An ink fountain for a printing press has a temperature-responsive element for compensating the adjustment of the spacing between the blade and the fountain roller to keep the thickness of the ink film fed by the blade substantially constant even under extreme temperature variations. The sub-frame of the ink fountain is pivotally mounted to the main frame of the printing press about a pivot axis generally parallel to the axis of the fountain roller, and the pivot angle is a function of the thermal expansion of the temperature-responsive element. In one preferred embodiment, the temperature-responsive element is elongated, received in a guide fixed to the sub-frame, and has a free end bearing against the bearing bushing of the fountain roller. In another embodiment, the temperature-responsive element is a side wall of the ink trough or is a plate parallel to the side wall of the ink trough, and rollers are journaled to the temperature-responsive element and bear against the surface of the fountain roller. In either embodiment, the temperature-responsive element is pre-stressed by a pull rod tending to pivot the sub-frame so that the temperature-responsive element bears against the sub-frame and the main frame.

    • A control system for a reversible screwing tool for tightening and loosening screws in a printing press or the like which includes a pair of angularly spaced pick-up devices coupled to the shaft of the tool for generating respective series of impulses. Monostable pulse generators are coupled to the respective pick-up devices, the generator coupled to the pick-up device in leading position, for counterclockwise rotation, being set to produce an output pulse which is substantially wider than that produced by the generator which is connected to the pick-up device in trailing position so that during counterclockwise rotation the output pulses from the generators timingly overlap one another. The generators feed into the input terminals of an AND gate which is, in turn, connected to a counter which counts the pulses resulting from counterclockwise rotation of the shaft. A relay interposed between the source and the tool automatically turns off the tool when a predetermined count is achieved thereby insuring that the screw is not excessively unscrewed from its tight condition. The relay is resettable in readiness for engagement of the succeeding screw. In the preferred embodiment of the invention the generator which is coupled to the pick-up device in leading position is responsive to the trailing edge of the received impulse while the generator connected to the pick-up device in trailing position is responsive to the leading edge of the pulse which it receives.

    • 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.

    • For use with an ink fountain having a trough with a flat sloping bottom wall and a fountain roller at the presented edge of the bottom wall, a moveable partition for dividing the trough into adjacent feeding and non-feeding areas. The partition consists of a trough-engaging portion having a straight face for engaging the bottom wall of the trough and a separate roller-engaging portion having an arcuate face for engaging the roller surface. Resilient sealing strips are secured to the faces thereof for sealing against the flat bottom wall of the trough and the cylindrical surface of the roller. The two portions are so arranged that their adjacent edges overlap to block the escape of ink, and are connected one to the other by a pivot which extends parallel to the roller axis in the region of the overlap. The pivot is fitted loosely to provide play in the plane of the partition so that when the trough-engaging portion is clamped downwardly and forwardly in the direction of the fountain roller, the roller-engaging portion is free to undergo rocking and translational movement for intimate seating of the arcuate face thereof on the fountain roller notwithstanding variations in the transverse positioning of the roller axis vertically and horizontally with respect to the bottom wall of the trough.
