摘要： A fluid supply system for a lithographic printing press in which a fountain roller journalled in the frame of the press and driven at a slow speed is partially submerged so that a film of fluid is formed on its surface. A distributor roller is journalled in the frame parallel to the fountain roller and spaced therefrom to form a gap. A ductor roller movable broadwise in the gap is supported by a pair of arms which are, in turn, rigidly supported by a shaft journalled in the frame. A driving arm having a thrust rod connected thereto is rigidly secured to the shaft. The driving arm is coupled to a cam follower which engages a rotary cam so that upon rotation of the cam the shaft oscillates to swing the ductor roller back and forth for successive engagement of the fountain roller and the distributor roller to convey fluid therebetween. Opposed way surfaces are provided at the ends of the arms oriented generally perpendicular to the plane of the arms. Mounting blocks carrying the ends of the ductor roller are slidable on the way surfaces. Paired springs are provided on opposite sides of each of the mounting blocks in working opposition to one another so as to define a normal position of the ductor roller with respect to the arms. Upon engagement of the ductor roller with either the distributor roller or fountain roller, any relative overtravel of the cam follower is yieldingly accommodated by the deformation of the springs. A set screw in each arm prestresses the springs and adjusts the normal position of the ductor roller.

摘要： 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.

摘要： An inking unit for a printing press including a source of ink, a set of ink transfer rollers for establishing an ink film, a distributor roller vibrated endwise for distribution of the ink film and a form roller for applying the ink film to a plate on the plate cylinder. The form roller has a shaft and an outer cylindrical shell, the latter being rotated by surface engagement. A bearing between the shaft and the shell permits relative axial as well as rotational movement. A cam of the cylindrical, or drum, type mounted on the shaft has an endless wavy groove in which is received a cam follower in the form of a roller extending radially inwardly from the sleeve so that the sleeve reciprocates through a single cycle as a result of a single relative rotation of the shaft. The shaft is driven at a speed which causes the frequency of vibration of the form roller to differ from the frequency of vibration of the distributor roller so that the ghost image on the form roller is constantly being displaced and dissipated both peripherally and axially with respect to the image on the plate resulting in substantially ghost-free printing. A clutch is provided for remote switching between two modes of operation.
摘要翻译：一种用于包括油墨源的印刷机的油墨单元，用于建立油墨膜的一组油墨转印辊，用于分配油墨膜的端面振动的分配器辊和用于将油墨膜施加到板上的成型辊印版滚筒。成型辊具有轴和外圆柱形外壳，后者通过表面接合而旋转。轴和壳体之间的轴承允许相对轴向和旋转运动。安装在轴上的圆柱形或鼓型的凸轮具有无端的波浪槽，其中容纳有从套筒径向向内延伸的滚子形式的凸轮从动件，使得套筒通过单个循环往复运动，结果轴的单个相对旋转。轴以一定速度驱动，导致成型辊的振动频率与分配辊的振动频率不同，使得成型辊上的重影不断地位移并相对于板上的图像导致基本上无重影的印刷。提供离合器用于在两种操作模式之间进行远程切换。
