摘要： In the feed device according to the invention for sheets taken individually from a stack which, after they have been registered, are fed to a printing machine, front markers (1) are provided which are connected fixedly in terms of rotation to a front marker shaft (2). To avoid complicated measures for adjusting the front markers (1) with the aim of adapting them to a curved contour of the fronts of the sheets, the feed device is fitted with a bending device (11, 20, 24) which acts in a steady-state manner on the front marker shaft (2). … A preferred exemplary embodiment has a bending device (11, 20, 24) interacting with swivelling means (14) for slanting the front marker shaft (2). … …

摘要： In an inking unit for a printing press having an ink duct with an ink-duct roller revolvable at a given speed therein, a transfer roller in rolling contact with the ink-duct roller, the transfer roller having an outer cylindrical surface formed with a plurality of helical ridges thereon, and a distributor roller revolvable at press speed greater than the given speed of the ink-duct roller, the transfer roller being rollable on the distributor roller for transporting ink film from the ink-duct roller farther into the inking unit, the improvement there including mutually meshing gear means carried by the transfer roller and the distributor roller, the transfer roller being drivable by the distributor roller via the gear means, and means for applying contact pressure of such magnitude between the transfer roller and the distributor roller during rolling of the transfer roller on the distributor roller that there is continuous contact between the surface of the distributor roller and the surface of the transfer roller located between the ridges, the ridges being in relatively low-pressure contact with the ink-duct roller revolving more slowly than the distributor roller.

摘要： In order to achieve a clear printed image which is, in particular, free from so-called "gear marks", the metering roller in a damping mechanism for an offset printing machine having a pair of rollers comprising an applicator roller and a metering roller driven is driven by a gear wheel which engages with a driving gear in a gear train, the applicator roller being driven exclusively by friction and braking moments acting on the applicator roller being compensated to such an extent by such a high circumferential speed of the metering roller relative to an associated plate cylinder that the applicator roller, in a continuous printing position of the damping mechanism, rotates with a circumferential speed which is in the order of 0.5 to 2.0% lower than the circumferential speed of the plate cylinder.
