摘要： Automatic transfer of one (4a) or a group or package (4'a) of secondary or scrap sheets from a stack (4) over a stack (3) of primary or good-quality sheets on which printing is to be effected, is controlled, for example by a microprocessor control system (12) by placing a stack (4) of secondary sheets adjacent the stack (3) of primary sheets. A secondary sheet transport system (9, 10, 11; 20, 9; 26, 27, 229, 32, 33) grips at least one (4a) or a package (4'a) of secondary sheets and pushes, pulls or similarly transfers the sheet or package of sheets over the topmost one of the primary sheets. To facilitate separation of sheets, a blower is provided blowing air against the edge of the secondary sheets where pick-up is to be effected. Automatic control is possible by introducing into the control unit monitoring signals derived from the printing machine.

摘要： To attach a printng plate (2) to a plate cylinder (1) having a groove therein, the groove has converging inner walls (10, 11) and a two-part attachment clamping wedge (5, 6) is provided, the clamping wedge being spring loaded to clamp an end portion (A) of the plate (2) between one part (6) of the wedge and an adjacent side wall (10), the other end portion (E) of the plate (2) being clamped between the two parts (5, 6). The parts have, in cross section, approximate trapezoidal shape. The two-part clamping element permits release of the plate by pressure (P) from the outer face of the cylinder (1) counter the force of a spring (8) which presses the clamping wedge parts (5, 6) towards the outside via a support plate (4). Preferably, the arrangement is symmetrical about a centerline (M) so that slight canting or tilting of the clamping wedges is possible for easy release of the plate (2) after installation. Upon rotation, centrifugal force acting on the clamping parts tightly clamps the printing plate (2) in position.

摘要： A system for detecting missing or superimposed sheets fed to a sheet processing machine uses a measuring device for generating a signal increasing with the number of superimposed sheets and an evaluating device for emitting an electrical signal when irregularities occur. A pulse transmitter is synchronized to the sheet feed mechanism and operates to emit an initial and final pulse timed to the sheet feed. Electronic storage is reset upon the initial pulse, and operates to integrate values of the measured signal until the final pulse is received. Upon receipt of the final pulse, the stored value is compared to a reference value to detect any irregularities. Preferably a microcomputer is used for signal processing.

摘要： To prevent uncontrolled movement or flutter of a trailing end of a sheet being removed by a chain conveyor from a delivery drum (7) of a printing system (1), the sheets are gripped by grippers (10) connected to cross struts (9) of two chains (8), and engaged by sheet engaging brushes (19, 22) or rollers or ducts (30, 34) with differential pressure application, such as compressed air, to urge the sheets against a sheet guide vane (13) or strip. To prevent interference with the grippers (10) on the chain conveyor, the sheet guide elements are lifted off from the sheets upon passage of the grippers by a cam-cam follower arrangement. The cams may be secured to the gripper structures in the form of cam curves (11), engaged by cam followers (17, 22) which pivot or tilt cross rods (15, 20) to lift the brushes off the sheets; or a cam (25; FIG. 2) can be placed on the delivery drum, controlling cam followers (27, 31) which, over a linkage, lift off the engagement elements (30, 34) when the grippers come therebeneath, but permit engagement thereof when the grippers have passed, to control movement of the trailing portions of the sheet.

摘要： An arrangement for the transfer and conveyance of sheets between first and second printing units of a multi-color lithographic press which includes a receiving drum in the first printing unit, a feed drum in the second printing unit, impression cylinders associated with the drums, an endless chain, which includes links joined by pins, trained about the drums, and a guide rail following the path of the chain. A plurality of gripper carriages moveable on the rail are each coupled to the chain for movement therewith by a carriage coupler, each coupler including a drive roller on the chain mounted outboard parallel to the pins thereof. Each gripper carriage includes a yoke for snugly embracing the drive roller on the chain. The feed drum includes a radially mounted drive fork for engaging the cam roller of each gripper carriage as it comes into the vicinity of the feed drum in order to achieve a condition of accurate register between the feed drum and the gripper carriage. Each yoke is resiliently mounted with respect to its carriage to permit slight accommodating movement of the carriage along the direction of the chain so that each carriage is sequentially in a phase position which is dependent only upon the phase position of the feed drum for accurately phased transfer of the sheet with respect to the associated impression cylinder.

摘要： An arrangement for securing pure skew adjustment of a cylinder, for example, a plate cylinder in a sheet-fed rotary printing press relative to an adjacent blanket cylinder. A bearing assembly at one end of the plate cylinder includes a cylinder bearing telescoped over the shaft and having flat support surfaces thereon facing radially outward in opposite directions. A guide bearing having a cylindrical outer surface is formed with a central window for receiving the cylinder bearing. The window defines a pair of flat inwardly facing way surfaces spaced parallel to one another for snug reception of the flat support surfaces on the cylinder bearing. The window also defines side walls spaced sufficiently to permit freedom of adjustment of the cylinder bearing along the way surfaces. An eccentric sleeve is fitted between the guide bearing and the frame with means for rockably adjusting the same to move the plate cylinder toward and away from the blanket cylinder thereby to vary the impression. A second adjustment is interposed between the cylinder bearing and the frame for locating the cylinder bearing in a desired position along the way surfaces thereby to adjustably skew the plate cylinder with respect to the blanket cylinder. A key anchored to the frame is provided for holding the guide bearing in a phase position in which the way surfaces therein are constantly oriented perpendicular to a plane which normally contains the axes of the cylinders, notwithstanding the rocking movement of the sleeve.

摘要： An ink fountain including a frame defining a horizontal slot adjacent the fountain roller. Arranged side by side in the slot is a metering assembly in the form of a series of flat slides each having a cam assembly at its rear end for adjusting the position of the slide with respect to the fountain roller thereby to meter ink in predetermined thickness in respective zones. Each slide is formed of a body having secured thereto a rectangular tip portion formed of resilient plastic. The tip portion of each slide has embedded in it a blade of wear resistant spring metal, the blade being coextensive with the width of the slide and so oriented as to present a flat face to the fountain roller defining, with the fountain roller, a sharply acute cusp. The rectangular tip portion of each slide is relieved in the region just behind the spring metal blade to permit the blade to flex broadwise resiliently and accommodatingly when the slide is advanced to bring the edge of the blade against the surface of the fountain roller thereby to achieve a seal between the blade and the fountain roller with only limited reaction force being exerted between them.
