    • The invention is concerned with improvements in a web draw-in system for a web printing press comprising printing units with register rolls around which the web is trained, a draw-in bar to be attached to the leading end of the web and two tractive elements extending along the side frames of the press and guided by bend pulleys following the web path in the press. The tractive elements extend from one drum at one end of the press to a further drum at the other end so that they may be wound onto and unwound from such drums moving the draw-in bar along the web path. In order to ensure a low degree of strain on the tractive elements, and for this reason a substantial removal of stress from the servo means moving the register rolls the drums are each driven synchronously in either direction of rotation by a main drive connected with them via respective differentials, more especially in the form of harmonic drives or other epicyclic systems whose further input shaft is connected with an ancillary drive means which is controlled by a monitoring device sensing the tension in at least one of the tractive elements. The ancillary drive device may thus be turned in either direction. Near a position halfway along the web path there is a locking device for locking the tractive elements except when the web is being drawn in or the tractive elements are being rewound. The monitoring device are operative when the tractive elements are so locked.
    • 本发明涉及一种用于卷筒纸印刷机的纸幅牵引系统的改进,其包括具有记录辊的打印单元,卷筒纸被卷绕在其上,待连接到纸幅的前端的拉入条和两个牵引元件 沿着压机的侧框架延伸并且沿着压机中的幅材路径的弯曲滑轮引导。 牵引元件从压榨机一端的一个滚筒延伸到另一端的另一个滚筒,使得它们可以卷绕在这样的滚筒上并使其从卷筒纸路径上移动拉入杆而退绕。 为了确保牵引元件的应变程度低,为此,移动寄存器的伺服装置的实质上的应力消除滚筒与驱动器连接的主驱动装置的驱动方向各自同时旋转。 更具体地是以谐波驱动器或其它行星系统的形式,其进一步的输入轴与辅助驱动装置连接,辅助驱动装置由监控装置控制,该监视装置感测至少一个牵引元件中的张力。 因此辅助驱动装置可以沿任一方向转动。 在沿着路径中途的位置附近存在用于锁定牵引元件的锁定装置,除了当卷材被拉入或牵引元件正在重绕时。 当牵引元件被锁定时,监控装置可操作。

    • Positioned adjacent to the delivery end of a device for folding sheets delivered from a printing press is a sheet pick up device to intercept a sheet for test purposes. The mechanism to intercept the sheet includes a receiving roller carrying a guide belt which is moved into the delivery path and then transfers the sheet to a second guide belt for holding the test sheet between the two guide belts for delivery to a special delivery means where the sheet can be inspected. The roller is supported on a movable arm which is synchronized with the delivery belt of the folding apparatus, and the guide belts are arranged to move at a speed faster than the delivery belts. The removal of a sheet for test purposes does not interfere with the delivery of the other sheets and operations do not have to be stopped to test a sheet.

    • A web feed printing press, more especially a rotogravure press, has a longitudinal shaft for driving printing units and a device for driving the web draw rolls. In order to achieve a simpler design without any direct mechanical connected between the draw rolls and the longitudinal while still ensuring accurate drive operation the drive device for the pair of draw rolls comprises a main motor and an auxiliary motor each with an adjustable speed of rotation. A differential drive has two inputs and one output. The speed of rotation of the main motor is varied in a way dependent on the speed of rotation of the longitudinal shaft and the speed of rotation of the auxiliary motor is varied in accordance with the speed of rotation of the longitudinal shaft and of the tension of the web of paper to be printed. The auxiliary motor is coupled with a differential element of the differential drive, which is preferably in the form of a harmonic drive, so that a speed difference in the rotation between, on the one hand, the input of the differential drive connected with the main motor and, on the other hand, the output of the differential drive connected with the pair of draw rolls may be produced.

    • In the case of a device for holding offset or other plates on the plate cylinder of a printing press with two clamping members on the two sides of a well running in the axial direction of the cylinder and each having a gripping part of clamping the hooked ends of the plate and at least one of the members may be rocked about an axis parallel to the axis of turning of the cylinder, the necessary width of the well may be greatly decreased in the clamped condition of the system of one of the clamping members, that is able to be rocked, takes the form of a segment bar having a cross-section that is generally three-sided and segment-like. This bar may be placed next to an outer face of the cylinder body and has an outer face lined up with and continuing the outer face of the cylinder body. The segment bar further has a convex, part-cylindrical base face at a limit of the outer face of the bar, the convex base face fitting into a socket therefore in the cylinder body, the socket being part-cylindrical and concave with a curvature in keeping with the form of the convex face. Because the well is narrow there is more space for the printing image on the plate cylinder.
