Abstract: A metering strip for an ink fountain of a printing press for metering printing ink, especially a doctor blade, is fastened in a pivoting mount and has a cylindrically shaped edge with a radius in the range between 0.3 and 1.5 mm. The edge is pressed against an inking roller and forms a metering nip with this roller for the printing ink to be metered. Axial recesses merge on both sides of the metering strip with the cylindrically shaped, wear-resistant edge that covers an angular range of more than 180.degree..

Abstract: The ends of an inking- or dampening-device roller are mounted in respective bearing arrangements displaceable along a control surface co-operating with a guide part. The control surface includes an adjustment zone and a further zone. The adjustment zone runs substantially parallel to an angle bisector of an angle formed by two lines connecting the axis of the inking- or dampening-device roller to the respective axes of the adjacent stationary rollers. Only a single linear drive is necessary for displacing the bearing arrangement.

Abstract: A rotary printing press with rubber-rubber printing units arranged essentially vertically above one another. The rubber cylinders of at least one rubber-rubber printing unit can be retracted from one another in the formation of a usable gap between the two rubber cylinders.

Abstract: The present invention describes a device for moving rollers and in particular rollers of a printing press in two independent directions. Movement in each direction is independent of movement in the other direction. The roller has trunnions which are mounted in roller locks. The roller locks are then mounted on a frame of the printing press. Mechanisms inside the roller lock position the roller lock in one direction with respect to the frame and other mechanisms inside the roller lock position the roller in another direction with respect to the roller lock. This mechanisms are independently controlled and movement of one mechanism is independent of the movement of the other mechanism. By independently controlling these mechanisms the roller can be engaged, disengaged and adjusted with respect to the frame or any components mounted on the frame.

Abstract: A reversible printing unit is equipped with a central distributing roller (9), with which a first transfer cylinder (8) and a second transfer cylinder (12) can be engaged or disengaged independently from one another. A respective dampening mechanism (10) and (24) is associated with each of the transfer cylinders (8) and (12). Depending on the direction of rotation or the mode of operation of the printing unit, the transfer cylinders (8) or (12) and the rollers following them act as dampening rollers or inking rollers. Modes of operation with indirect dampening, pre-inking of the inking mechanism with feed of dampening agent, and rapid and thorough washing of the rollers of the inking and dampening mechanism are also possible due to the independent adjustment of the respective transfer cylinders (8) and (12).

Abstract: The inking device of a printing machine is composed of an inking roller, providing an elastic surface, the inking roller producing a pre-dosed ink layer on the inking rollers. A dosing strip wipes off the pre-dosed ink layer and leaves the quantity necessary for the transfer onto a stereo cylinder, the wiped off excess ink running off freely. For self-cleaning purposes, the dosing strip carries out a movement preferably in the direction of the circumference of the inking roller, so that the area forming the dosing slot which is in contact with the inking roller is continuously modified.

Abstract: A traveling platform unit which is movable in the horizontal direction, for loading and unloading a printing paper on a roll stand. The roll stand has swivel arms and is part of a web-fed rotary printing press which uses the printing paper rolls. The traveling platform is equipped with lifting elements acting together in pairs, which permit aligning of the paper rolls with a paper roll bearing axle of the roll stand while allowing paper rolls of different diameters and widths to be brought for clamping between pairs of the swivel arms of the roll stand or to be removed from the swivel arms of the roll stand.

Abstract: For the drawing in of material webs in web-fed rotary presses a driven draw-in element is used which has a finite length extent and which is moved along different, preadjustable draw-in paths. Guides are disposed along the draw-in paths which provide interruptions which improve the accessibility of the printing units of the presses. For the passage through these guideless regions the draw-in element is stiffened.

Abstract: A metering blade for zonally metering a liquid film comprises a plate body having a working edge usable in an arrangement in which the setting member bears against the plate body and bridges a portion thereof against a rotating roller comprises a blade with a plurality of zonal setting portions of a material capable of being displaced by resilient flection adapted to be arranged adjacent a setting member which includes intermediate portions between a working edge and the opposite edge compensating for the setting wherein the setting portions are at least 3 mm in thickness and each intermediate portion includes a web part having a thickness which is not more than 1/5th the thickness of the setting portion and has a width amounting to at least five times the thickness of the web. The blade has a working edge with a reinforcement adjacent each web.

Abstract: Each individual, freely rotatable ring of a spiral-type ductor is mounted on an eccentric which is supported for rotation on a multi-eccentric shaft is angularly offset relative to its adjacent eccentric portion by at least an amount corresponding to the number of rings. The multi-eccentric shaft is connected to the drive of an inking system directly while the eccentric is connected thereto through a pinion, a pinion shaft, a gear and a separate sequential transmission with an integral speed ratio. In consequence, the center of the ring describes a curve which is flattened in the zone where the ring is in contact with an inking roller. The contact duration is thereby extended without varying the speed.

Abstract: The disclosure concerns a nine-roll or ten-roll printing mechanism, in which the directions of rotation of the rolls have to be reversed individually according to a printing program. The driving connection to the plate rolls is effected through two oppositely rotating impression roll gears which are rotatably mounted on the axle of the impression roll. The impression roll gears can be coupled to the axle of the impression roll by means of remotely operable couplings. A sliding gear is associated with each plate roll. The sliding gear selectively engages one or the other impression roll gear. An indexing wheel corresponds to each sliding gear and is mounted slidably on the plate roll axle. The width of the sliding gears is selected so that an idling setting is excluded. Each plate roll is connected with its associated offset roll by means of a rotation-secure driving connection.

Abstract: An apparatus for cyclically decelerating and accelerating a ductor roller which has a journal which is mounted on a swing arm for rotation on the arm and is moved with the arm to selectively and alternatively engage the ductor roller with a first roller, such as a fountain roller and a second roller, such as a first roller of a printing press, is employed in inking and damping units of such presses. The apparatus includes a bearing head of the spring arm which provides a rotatable mounting for the journal of the ductor roller and the arrangement includes a planetary gear system connected to the journal and to a free wheel element with a controllable brake acting between the planetary gear system and the bearing head of the swing arm in an arrangement which permits the free wheel element to rotate after the braking system has been engaged to cause the winding or tensioning of a spring, such as a spiral spring, which is disposed between the free wheel element and the journal of the ductor roller.

Abstract: A ductor or film-transferring inking mechanism for printing machine, particularly for offset presses, which comprise a plate cylinder having a printing form, an ink reservoir and a ductor roller mounted for rotation so as to dip into the ink reservoir and at least one additional rotatable distributor roller engageable between the ductor roller and the plate cylinder. A rotatable takeoff roller is associated with one of the distributor rollers of the inking mechanism and is adapted to engage with one of these rollers and take up the periodically unused and no longer applicable ink from this roller and to be moved to a position so as to be engageable with a stripper roller so as to transfer this ink to the stripping roller. A stripper such as a ductor blade is engaged with the surface of the stripper roller and it strips the ink therefrom and permits it to return into either a separate container or directly back into the ink reservoir.
