A device and a method for folding a print substrate web is disclosed. The device has devices for quarter folding and for cross-cutting the print substrate web for severing individual products as well as devices for cross folding. As viewed in the transport direction of the products, an arrangement for dividing the product stream is provided after a second quarter folding device, the arrangement conveying the successive products to a first and a second conveyor belt in an alternating manner.

A web press, in particular a variable format book web press, variable format newspaper web press, or variable format periodical web press, has printing units having printing devices or groups of printing devices for applying ink to a paper web. The printing devices or groups of printing devices are constructed without rotating impression cylinders and are designed to apply ink to the paper web in a noncontacting manner.

Variable format web press

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 transfer cylinder sleeve is provided for an offset printing machine including an inner carrier layer, a compressible layer and a covering layer, where at least one of the layers has a joint or a gap and provided that when a joint or a gap is used in the covering layer, then the transfer cylinder sleeve is applied to a transfer cylinder in register so that the joint in the covering layer rests opposite a tension channel of a plate cylinder during rolling contact of the transfer cylinder with the plate cylinder. Optionally, a non-stretchable layer is provided between the compressible layer and the covering layer, or alternatively, a non-stretchable material is provided in the compressible layer itself.

The printing-material web is guided in the same position and plane when the transfer cylinders are moved apart for the flying printing-plate change, so that contact between the web and the transfer cylinders and smearing are avoided, that is to say undesired contact with ink-carrying parts. When the transfer cylinders are moved apart, web-guiding elements at the web inlet and/or web outlet support the printing-material web on both sides during the plate or sleeve change by supporting elements which are narrow or act at points and can be displaced transversely with respect to the printing-material web. The printing-material web continues to be guided in the same position and plane, and smearing is avoided.

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.

Form cylinder of a rotary printing press, in particular of an offset printing press

A blanket cylinder has a rotational axis and a concave surface, concentric to the axis and extending over a printing width of the cylinder, for receiving a flat rubber blanket made of elastically deformable material. The cylinder has a recess concentric to the axis, extending over the printing width, and a film fitted in the recess The film has an outside surface which forms the concave surface of the blanket cylinder.

In order to reliably tension the legs of the carrier plate by means of tongues fastened to spindles, one spindle is designed as a hollow spindle which is mounted in a bore of the cylinder gap of the printing-unit cylinder, and the other spindle is mounted in the hollow spindle.

A rubber cylinder sleeve for web-fed rotary offset printing machines has a covering layer which is a finite layer having a joint location, the joint location being filled with a compressible material.

Rubber cylinder sleeve, especially for web-fed rotary offset printing machines

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.

Double printing unit of a rotary printing machine

A cylinder sleeve for all offset web-fed rotary printing machine comprising a carrier sleeve having a joint location and about which is arranged at least one compressible layer, also having a joint location. Another layer of non-expandable material may be used on top of or within the compressible layer. The non-expandable layer may also have a joint location. A seamless outer layer is provided and disposed about the compressible layer and the non-expandable layer, if so provided.

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.

Film inking unit for a rotary printing machine

A device for reliably and economically moving two doors that are movably mounted on a side wall of a printing group in a rotary printing machine for closing openings in the side wall that are proximate printing group cylinders mounted in the printing group, includes a toggle lever articulately connected between each of the two doors and the side wall and is operated by a selectively actuatable working cylinder.
