    摘要： Die Erfindung bezieht sich auf eine Vorrichtung zur Umwicklung eines Druckformzylinders mit einem flexiblen Druckbildträger, wobei im Inneren des Druckformzylinders eine erste Wickelspule zur Abwicklung eines Druckbildträgers, der auf die Mantelfläche des Druckformzylinders aufziehbar ist und eine zweite Wickelspule zur Aufwicklung des auf die Mantelfläche aufgezogenen Druckbildträgers vorgesehen sind. Am Druckformzylinder ist in dessen Umfangsfläche eine einzige Öffnung zu einer Grube im seinem Inneren ausgebildet ist, in der die erste und die zweite Wickelspule gemeinsam angeordnet sind. Aus dieser Öffnung ist der Druckbildträger von der ersten Wickelspule auf die Mantelfläche und von dieser auf die zweite Wickelspule wickelbar. Die Vorrichtung ist dadurch näher charakterisiert, daß ein eine Umspulmechanik (4) für den Druckbildträger (3) abstützendes Lagerungsteil (30) aus dem Inneren des Druckformzylinders (1) im in der Druckmaschine eingebauten Zustand entnehmbar angeordnet ist.

    摘要： A winding assembly especially suitable for use in conjunction with a system for automated imaging of lithographic plate material, including on-press imaging systems. A feeder spool (105) installed within a plate-support cylinder (12) contains a rolled supply of plate material, which wraps around the cylinder (12) and is received by an uptake spool (110), also located within the cylinder (12). The assembly is driven by the same power source used to rotate the plate-support cylinder (12), and maintains a strong tension along the wrapped material.

    摘要： The improved printing press comprises: a single plate cylinder that allows press plates for n colors to be disposed cylindrically at predetermined intervals; a platemaking unit that is disposed on the circumference of the plate cylinder for preparing a single press for one color or n platemaking units that are disposed on the circumference of the plate cylinder for individually preparing press plates for single colors; an ink supply assembly for the n colors, an impression cylinder whose diameter is one-nth of that of the plate cylinder, said impression cylinder having a single sheet of printing paper wrapped around it and delivering the printing paper after it has made n consecutive revolutions; and, optionally, either one or both of a rubber-covered blanket cylinder interposed between the plate cylinder and the impression cylinder and a dampening water supply assembly for supplying dampening water to the press plate or plates. In the first case where only one platemaking unit is used, the printing press is applicable to both direct and offset printing on whichever types of press plates (letterpress, intaglio or lithography) or irrespective of whether dampening water is used or not on lithographic plates. The press obviates the need for registration in multicolor printing and can be operated even by unskilled operators. In the second case where a plurality of platemaking units are used, the printing press enables all press plates of interest to be prepared simultaneously on the single plate cylinder even in the process of multicolor printing, thereby shortening the platemaking time and, hence, the overall process time including platemaking and printing operations. The press is not only sufficiently simple in construction to realize a compact and small-sized system but also very easy to operate, permitting printing to be done at comparatively high speed.

    摘要： A plate material tensioning and advancement mechanism is disposed in parallel relation to a cylinder (104), such as a plate cylinder of a printing press, so as to separate the plate material into distinct printable sections. The plate material tensioning and advancement mechanism (102) assists in supplying tension to the plate material (112) via a tensioning roll (114) during printing operation and assists in winding fresh plate material about the cylinder during advancement operation by reducing the tension on the plate material and by optionally applying tangential force to the plate material via a winding roll.

    摘要： The invention relates to a holding device (1) for a flexographic printing sleeve (2), which comprises at least one receiving member (3) exhibiting a cylindrical side surface over which a printing sleeve can slide, said receiving member being able to rotate around its longitudinal axis and around the sleeve longitudinal axis. According to the invention, the receiving member comprises two or more shoulders (4) with differing diameters and the holding device comprises a second identical receiving member (3). Both receiving members are placed in such a way that they can rotate around the same longitudinal axis and are oriented toward each other with their small shoulders. At least one of the receiving members can be moved along said longitudinal axis in such a way that the distance between said two receiving members can be adjusted.
