摘要:
A printing group, which includes at least one rotation element, that can be rotated about its longitudinal direction, and than can also be displaced axially, includes a drive. That drive for the rotational element can be a drive motor which is independent of the drive of the printing group cylinders. The drive can be effected through a rotationally fixed and coaxially linked drive wheel, and a flexible drive. In order to achieve a lateral travel of the rotational element, the printing group is provided with a supplementary drive motor.

A printing machine has at least one printing unit on which a web of material, which is to be imprinted, is imprinted by offset printing in a variable cut length. A folder is mounted downstream, in the direction of travel of the printed web, of the at least one printing unit. The folder may be located directly or indirectly from the at least one printing unit and has a variable cut length.

A rubber blanket is provided with reinforcement rails on one or both of its ends. These reinforcement rails are positionable in a narrow channel in a rubber blanket cylinder. The reinforcement rail or rails extend beyond the ends of the channel. Rubber blanket cylinder tensioning devices engage the extending ends of the rubber blanket reinforcement parts.

A printing unit consists of at least two printing groups, which are placed vertically above each other, in a printing machine. Each of the printing groups includes a printing cylinder, an inking unit with at least one inking roller, a dampening unit with several dampening rollers arranged in a line, and a transfer cylinder that cooperates with the printing cylinder. The inking cylinder and the dampening roller, in an operational state in which they are adjacent the printing cylinder, form an obtuse opening angle with the printing cylinder. The rollers of the dampening unit are arranged with at least the first and last rollers in the roller train arranged inside an acute angle depending from the transfer cylinder. A horizontal line extending from the transfer cylinder defines an opening angle of less than 45° with the rollers of the dampening unit. A printing forme is fed to the printing cylinder through an obtuse angle between the dampening roller and the inking roller.

A printing group of a rotary printing press includes at least one forme cylinder and at least one transfer cylinder. The forme cylinder has at least two printing forme end receiving channels. These two channels are spaced circumferentially. At least one of these forme cylinder end receiving channels rolls off against a channel in the transfer cylinder. One of the forme cylinder end receiving channels is at least partially covered by a printing forme carried by the forme cylinder.

A plurality of inking blade plates are positioned in abutting fashion between cooperating insertion and clamping strips to form an inking blade. A temperature differential is created between the blade plates and the strips which are then allowed to return to a common temperature. This creates a uniform spacing between each of the inking blade plates in the inking blade. The resulting inking blade is usable with an ink ductor roller in a rotary printing press.
