Abstract: A guide roller and a method for manufacturing a guide roller combines a cost-efficient manufacture and hard, wear-resistant webs for contact with a substrate. An at least one web consists of a second material which differs from a first material of a base body. The webs or the at least one web is applied to the base body by means of a deposition welding process, a thermal spraying process, a plasma transferred arc spraying process, a laser deposition welding process, or by means of an additive manufacturing process. Guide rollers of this type are used on machines that process substrate webs or substrate strands, such as web-fed printing presses, systems for processing already printed substrate webs or similar systems.

Abstract: A folding apparatus of an offset web-fed printing press includes a first transport means formed as belt conveyor system for a web-shaped printing material and configured such that belts thereof can be driven at a speed, which corresponds to the speed of the printing material, and a first cutting means arranged in the region of the first transport means configured such that it severs the printing material in a format-variable manner in those sections not covered by the belts of the first transport means, and a second transport means arranged downstream from the first transport means and formed as belt conveyor system, the belts of which are offset relative to the belts of the first transport means transversely to the transport direction of the printing material, configured such that the belts thereof can be driven at a speed larger than the speed of the belts of the first transport means.

Abstract: A component part for use in printing presses or paper- and substrate-processing machines, wherein the component part has at least one first region made of a first material with first physical properties, and wherein the at least one first region has a functional surface, which is in contact with a web- or sheet-shaped substrate and which is subject to wear. The component part provides a solution, by means of which the reaching of degrees of wear or also of wear limits can be easily determined without using aids. The component part is configured such that adjacent to and/or spaced apart from the at least one functional surface, at least one second region is at least partially enclosed by the first region.

Abstract: A print control strip for printing onto a substrate, which moves in a printing direction X during a printing process, with a substrate width B, which extends perpendicularly to the printing direction X, wherein the print control strip extends at least over a portion of the substrate width B, wherein the print control strip has at least one row in the printing direction X, and wherein one or each row has a plurality of measuring fields arranged next to one another perpendicularly to the printing direction X, and wherein each measuring field has a center of area and a leading edge in the printing direction X. The center of area or the leading edge of at least one measuring field is arranged to be offset in or opposite to the printing direction X to the center of area or leading edge of an adjacent measuring field of the same row.

Abstract: A folding roller for folding signatures in a folding apparatus comprises a cylindrical folding roller element comprising a jacket surface at least partially having an elastic coating that is compressible. As such, different folded products and/or folded products of different thicknesses can be produced without a change of the nip between the folding roller pair with consistent folding quality, and an adjustment of the nip is also not required during a production run printing or an ongoing production.

Abstract: A method and device for carrying out a reel splice to avoid the fluttering of tails makes it possible to allow the tail to also adhere across its entire length, in particular on a web with high mechanical strength. When using a fluid-repelling substrate, an adhesive-free liquid is applied to a new roll and/or to at least a portion of the side of the tail facing the web. The method and device can be used in reel splicers which process fluid-repellent substrates, such as for example plastic films, metal films or laminated laminates, so that a sticking out or fluttering of the tail is avoided.

Abstract: A plate cylinder includes a plate cylinder body having a longitudinally-extending first hole and a longitudinally extending plate-receiving gap connected to the first hole, the plate cylinder body having a longitudinally-extending second hole parallel to the first hole; and a lock-up mechanism including: a torsion bar extending in the longitudinally extending hole and having a surface for contacting an end of a plate located in the gap; a swing bar extending longitudinally in the second hole and being movable perpendicular to a longitudinal direction due to the second hole being oversized compared to dimensions of the swing bar within the second hole; a lever connecting the swing bar and the torsion bar, the torsion bar being rotatable as the swing bar moves within the second hole; and an activator for rotating the torsion bar. A printing press and methods are also provided.

Abstract: A knife strip, cutting bar and adjusting device are provided by means of which an exact adjustment of the knife height is ensured for the entire service life of the adjusting device or of the knife bar, or by means of which the use of an adjusting device can even be forgone completely. An adjusting device includes a knife strip wherein at least one stop surface is formed in the area of at least one outer edge. An adjusting device includes at least one stop against which the at least one stop surface of the knife strip is placed. A knife bar includes at least one stop against which the at least one stop surface of the knife strip is placed.
