A sleeve, in particular a rubber-blanket sleeve, for a printing press is disclosed. The sleeve having a construction which has at least two layers, having an inner layer which is configured as a carrier layer and an outer layer which is configured as a covering layer and serves for pressure transfer, the sleeve having a hollow-cylindrical design with a cylindrical inner surface and a cylindrical outer surface. The inner layer which is configured as a carrier layer is convexly or concavely curved on the radially outer side, a layer which adjoins the carrier layer having a curvature on a radially inner side which is complementary to the curvature of the radially outer side of the carrier layer.

Apparatus and method for a printing-press cylinder sleeve

An automated method is provided for carrying out a production change, which is specific to the printing plate, on a printing press. After a first print job is printed on a printing press, the printing of the first print job is stopped automatically after a predefined print run level has been reached or another termination criterion for the first print job has occurred. Parameters required for printing a second print job which follows the first print job are loaded automatically by the printing press. Before or after the parameters of the second print job are loaded, a printing plate change is automatically carried out on the printing press, thus achieving production readiness for the second print job. The second print job is then either started automatically, or a production readiness signal for the second print job is generated automatically.

A non-flowing protective medium is applied in a finely distributed manner through a metering nozzle by means of blown air to the non-printing regions of at least one roll of an inking unit or damping unit and/or the non-printing regions of at least one transfer cylinder or forme cylinder, forming a thin-layer protective film. Ink is thereby prevented from drying out in non-printing regions of the rolls and cylinders of the printing unit, and the tack is thus kept at a low level, in order to reduce the risk of web breaks.

A form cylinder is provided with a circumferential surface which is convexly curved in the axial direction, such that the convex profile, determined by calculation, of the circumferential surface varies in such a way that the diameter of the form cylinder is largest in the axial center and smallest at the lateral edges.

A fiber-reinforced plastic base body is first of all provided with a coating of hard rubber or thermoplastic having a dispersed metal or ceramic content of 5% by volume to 80% by volume, and the coating is ground down to provide a smooth surface In a further step a layer of metal and/or ceramic, which has a printing function, is applied to the smooth surface, preferably by thermal spraying.

Large throw-off distances of the transfer cylinders in a double printing unit of a rotary printing machine operating on the rubber/rubber principle are achieved by enabling the two transfer cylinders to be set away from each other, and enabling the two form cylinders to be set away from the respective transfer cylinder. The form cylinder and the transfer cylinder of each printing unit have a drive connection via spur gears, the transfer cylinders are not in tooth engagement via their spur gears, and each printing unit has its own electric motor.

Disclosed is a film roller in an inking unit of a rotary printing machine. The film roller is equipped with an internal cooling system to eliminate irregularities in the ink transfer to the film roller and to improve print quality.

An arrangement for fastening a covering on a cylinder of a printing machine, the arrangement including a cylinder having at least one axially extending cylinder groove which defines a groove wall at an acute angle to an outer surface of the cylinder, and a covering including at least one flexible support plate having a leading flange and a trailing flange that are inserted into the cylinder groove so that the leading flange engages the groove wall and the trailing flange is adjacent the leading flange. A spindle is arranged in the cylinder groove so as to be rotatable between a release position and a clamping position, and a leaf spring is mounted on the spindle so as to press, in the clamping position of the spindle, the trailing flange and the leading flange against the groove wall.

The invention relates to a web-fed rotary printing press having a plurality of double printing units in which each of the printing units of the double printing units work together in the blanket--blanket method and each has its own drive. Transfer cylinders of each printing unit are driven independently. To permit a rapid change in production, both upon recto and verso printing, the transfer cylinders of the disconnectable double printing units are separable by eccentric bushings or swingable levers such that a web which passes through the printing press is conducted between them without being printed.

A drive for a printing group of a rotary printing machine having a form cylinder and a transfer cylinder, the transfer cylinder being swivelably adjustable through an angle, the form cylinder and the transfer cylinder each having journals. The drive includes cylinder gears attached to the journals so as to be in toothed engagement, an electric motor with a drive spur gear that drives the transfer cylinder, and a spur gear mounted on the transfer cylinder journal. The drive spur gear of the motor drivingly engaging the spur gear on the journal of the transfer cylinder in a circumferential area of the spur gear lying from a diametral midpoint of the transfer cylinder in a direction of a vertex of the angle of the swivel adjustment of the transfer cylinder.

Drive for a printing group of a rotary printing machine

In a printing unit with two printing groups working together using the blanket-to-blanket method, in order to rotate the form cylinder and the transfer cylinder equally during circumferential register adjustment, the transfer cylinders are drive connected via helical gears and the transfer cylinders and the form cylinders of each printing group are drive connected via straight spur gears. The drive of the printing unit is carried out on one of the helical gears. Circumferential register adjustment of a printing group is carried out by movement of its helical gear.

Drive with resister device for a printing unit of a rotary printing

A rotary printing machine having a side wall with an opening therein through which at least one cylinder can be accessed. In order to uncover the wall opening in the side wall, a door is provided that can be operated in a structurally simple manner, so that, in particular, a sleeve-type printing form or a sleeve-type rubber blanket can be changed through this opening. The door is divided in the area of the journals of the printing group cylinders into two door members, which are arranged on the side wall so as to be swingable away from the journals.

Journal mounted cylinders with swingable access doors

To positively lock in position a pair of eccentrically journalled blanket cylinders (3, 6), movable between three positions, namely in engagement with a first pair of plate cylinders (1, 4), or a second pair of plate cylinders (2, 5), or in engagement with neither plate cylinder, the blanket cylinders having a printing substrate passed therebetween for perfecting printing, the eccentric bearings (7, 8) for the blanket cylinders are secured to operating disks (9, 10) which, each, are coupled to a scissor-link arrangement formed by two pairs of links (16, 18; 17, 19), joined at a common pivot point. Pneumatic cylinder-piston arrangements move the pivot points (1618, 1719) to compress one of the scissor link pairs to V position, while the other link pair is moved to slightly over-center in-line position for a toggle or locking effect; when both scissor link arms are in half-open V position, the blanket cylinders are disengaged from the plate cylinders. Abutment stop means, located between the blanket cylinders, receive the pivot points, when the link arms are in essentially in-line or toggle position, and adjustment bolts (42, 43, 44, 45) can control the position of the scissor link arms, when in V position for accurate adjustment of the locked position of the blanket cylinders.
