Abstract: A method and apparatus for flatness measuring and measuring of residual stresses in a metallic flat product (1): The method includes bending the flat product (1) in a bending device (3) such that a planar flat product (1) forms an arc (5) with a target bending radius r0 after bending; measuring the contour and the actual bending radii r(y), in the region of the arc (5) of the bent flat product (1) at a plurality of positions along the width direction of the flat product (1); and determining the flatness of the flat product (1) taking into account the measured contour of the bent flat product (1).

Abstract: A method for altering the width of a strip-shaped rolled material (5), before, during or after hot rolling the rolled material in a hot rolling mill. The problem is to specify a method for altering width so that the length of a rolled out transition piece lying outside width tolerances can be reduced. Scrap losses are to be reduced. The crown of at least one working roll and/or at least one backing roll of a stand (7) is set as a function of a width error e=B?B between a setpoint width Bsetp and the width B of the rolled material (5), wherein the crown is increased when e>0 and the crown is reduced when e<0.

Abstract: A printing unit of a web-fed rotary press has a plurality of press units, each press unit having a form cylinder, a transfer cylinder, an inking unit and optionally a damping unit, and having at least one impression cylinder. Each form cylinder rolls on the respective transfer cylinder and each transfer cylinder rolling on an impression cylinder in a thrown-on position of the printing unit, in order to apply single-color printed images onto a printing material which is moved through between the transfer cylinders and the or each impression cylinder. Each form cylinder bears a plurality of printing images next to one another in the axial direction, by which corresponding single-color printed images are applied to the printing material.

Abstract: A folding former of a folder for a web-fed newspaper press has a former nose and a pivot point or pivot axis, the folding former being pivotable about the pivot point or the pivot axis. A former inclination angle is changed by pivoting the folding former to horizontally displace the former nose. A former spread angle is also changed as a function of the former inclination angle. To align the outer edges of sections to be folded in the folding former, the former inclination angle and the former spread angle are set as a function of the number of pages in the sections to be folded.

Abstract: A nine-cylinder satellite printing unit includes printing stations having a first, second, third and fourth transfer cylinder which a web passes through. The transfer cylinders are capable of being stopped when the printing assembly is switched off. A distance between each of the first and second transfer cylinders, the second and third transfer cylinders, and the third and fourth transfer cylinder is shorter than the distance between the first and fourth transfer cylinder. A guide roller keeps a supplied portion of the web away from the first transfer cylinder and another guide roller keeps a discharged portion web away from the fourth transfer cylinder when the first and fourth printing cylinders are respectively in print thrown-off positions.

Abstract: A draw-in device for feeding a plurality of printing stock webs, preferably paper webs, in which draw-in elements of finite length grasp the start of a paper web and draw it out of reel changers and draw mechanisms through printing units and up to folding units. An electronic memory is provided in which are stored the lengths of all possible feed paths in the printing machine and the draw-in elements can be switched on at different times corresponding to the different lengths of the feed paths and the resulting time differences at a given feed rate via an electronic computer connected with the memory and can be switched off simultaneously. It is also possible to refeed a web of printing stock which was torn during the print process so as to substantially reduce wasted paper.

Abstract: To position two relatively rotatable elements, for example folding jaw control elements of a folding jaw cylinder of a rotary printing machine, with respect to each other, and re-position the elements, a positioning drive (7), for example a motor coupled to a gear, which is coupled for rotary transmission to an axially movable shaft or rod element (10, 10'), movable, for example, under fluid, preferably pneumatic pressure. When projected, the coupling element is engageable with a positioning gear (12) on one of the elements (22) and, upon rotation of the element by the positioning drive, can effect re-adjustment of the angular position of the other element, upon engagement with a positioning gear (11) coupled thereto. The arrangement permits remote positioning and indication of relative position by a feedback transducer (13, 113), such as a potentiometer, which can provide position signals suitable for a display (B).

Abstract: To expand a U printing system having two plate-blanket printing couples first to form a Y system for 2/1 (or 1/2) printing and then, further, to a dual-U system for 2/2 printing, with minimum space requirement, the axes of rotation of the base blanket cylinders are spaced from a separating line (3) between two superposed, staggered printing systems by different distances. An expansion group having two expansion plate-cylinder blanket couples likewise has the axes of rotation of the expansion blanket cylinders at different spacing from the separating line. Thus, by merely shifting a vertically arranged single blanket cylinder, previously in engagement with a lower blanket cylinder to release engagement therewith and engage against an opposite, newly arranged blanket cylinder, a space-saving 2/2 printing station is obtained.

Abstract: To permit easy change-over between double-prime, double-verso (2/2) printing on a substrate web (5) and double-prime, single-verso (2/1) printing, the cylinders are arranged in printing couples so that first and second blanket cylinders (1, 2) are in printing engagement with each other, with the web (5) therebetween and printing couples including blanket cylinders (3, 4) independently of the blanket cylinders (1, 2) are in engagement with each other, with the web therebetween. One (3) of the blanket cylinders of the printing couples is eccentrically shiftable from engagement with the associated blanket cylinder into engagement with another blanket cylinder (2) so that said other blanket cylinder will function as an impression cylinder for one prime image, and as a printing cylinder for the verso image, while, at the same time, another prime image is being applied thereagainst by the shifted blanket cylinder (3).

Abstract: The inker includes a chambered doctor blade unit (1) which defines an ink retention chamber. The ink retention chamber has an ink retaining ridge or strip (33) which extends from an upper surface towards the lower surface leaving a narrow ink passage gap (1') between the lower surface and the lower edge of the ridge or strip so that, upon selective connection of the unit (1) through a releasable coupling connection (5) of ink from a primary ink supply (3) or from a secondary ink supply (24, 40) of ink capacity substantially less than the ink capacity of the primary ink supply, ink within the ink retention chamber can be expelled under pressure being applied into said chamber, for example by compressed air, or sucked back into the cartridge. The cartridge permits application of a small quantity of ink, for example of different color than that of the primary ink supply, without disassembly of the entire inker.
