摘要:
The invention relates to a printing blanket assembly for a blanket cylinder of a rotary printing press. The printing blanket assembly comprises a dimensionally stable support plate (02, 18) with two ends, one of which is the forward end and the other one is the trailing end with respect to the rotation of the blanket cylinder, these ends being fastened to the blanket cylinder with folded, printing-blanket free limbs (21, 22). The assembly further comprises a printing blanket (03, 19), fastened to the outside of the support plate (02, 18) and having a forward end (12, 31) and a trailing end (11, 32). Said printing blanket assembly allows for perfect printing also in the area of a gap between the limbs (21, 22) and can be produced in a simple manner. For this purpose, both ends (11, 12; 31, 32) of the printing blanket (03, 19) project beyond the bevelled edge (08, 09; 27, 28) of the pertaining limbs (04, 06; 21, 22) of the support plate (02, 18) and one support element (13, 14; 34, 36) for supporting said projection is disposed between the bevelled edge (08, 09; 27, 28) and the inside of the printing blanket (03, 19).

A printing blanket assembly for a blanket cylinder of a rotary printing press includes a dimensionally stable support plate, and a printing blanket fastened to the outside of the support plate. A leading end of the support plate and a trailing end of the support plate are fastened to the blanket cylinder by the provision of an angled or beveled, printing blanket free end. A filler is provided between the beveled end of the support plate and the inner edge of the leading and trailing ends of the printing blanket.

A printing form is either raised or is lowered by the use of a pressure device which includes a roller. The roller is arranged on a cross-beam in such a way that the roller can selectively be placed on, or taken off the forme cylinder, or a forme that is supported on the forme cylinder, by a device. The pressure device, or the cross-beam which supports the roller can be displaced in a manner such that the distance of the roller from the cylinder can selectively be increased.

A printing group of a printing machine includes a printing cylinder and an associated inking system which includes first, second and third ink distributing cylinders, in addition to a plurality of inking cylinders and rollers. Ink can be fed by the first distributing cylinder, along a first, front inking path, to the second distributing cylinder and along a second, rear inking path to the third distributing cylinder. An inking cylinder is displaceably arranged in the inking system such that the color of the inking system is maintained due to contact of the inking cylinder with the first distributing cylinder or the second distributing cylinder in accordance with the length of the roller of the second inking path.

A printing couple in a printing machine is comprised of at least three cylinders, a forme cylinder, a transfer cylinder and a counter-pressure cylinder. The counter-pressure cylinder forms a printing location or point in cooperation with the transfer cylinder. The transfer cylinder is mounted in at least one lever which can be pivoted about an eccentrically pivoting axis in relation to the rotational axis of the forme cylinder. When the three cylinders are in a print position, a connecting plane through the axis of rotation of the forme cylinder and the pivoting axis of the lever forms an angle of between 25° and 65° with a plane through the axis of rotation of the cylinder forming the printing point.

A printing machine is provided with a control panel for use in the printing machine's control. The control panel is located on one side of the printing machine which includes at least one printing unit which has at least one pair of cylinder. This at least one pair of cylinders are mechanically coupled to each other-by a drive connection and are driven for rotation by a drive motor that is independent of other printing units. This drive motor and the drive connection are located on the control panel side of the printing unit.
