Abstract: An apparatus and method for leading together a number of printed webs is disclosed. Using a device for leading together several printed webs into a multi-layer web sandwich with a harp formed by the deflection rolls assigned to the individual printed webs, the inclusion of air between the webs can be prevented, in that a deflecting web sandwich guide is provided in the exit area of the harp and lies at right-angles to the running direction of the web sandwich.

Abstract: A method for controlling the cut register in a web-fed rotary press, includes registering an actual value measurement of a position of cut register marks on a printed material web by measuring positions of printing cut register marks on the printed material web, using the measured positions in control loops as actual values of positions of cuts for cut register control, and correcting a first set value of a cut register setting element assigned to the printing material web based on a mathematical model for an error contribution of a proportion of the path of the printing material web that is not registered by the actual value.

Abstract: In a method for controlling the cut register in a web-fed rotary press, in which the position of the cut in at least one printing material web is set by adjusting the rotational speed of at least one pull unit conveying the printing material web, the rotational speed change carried out on the pull unit is also carried out simultaneously on all the pull units that follow in relation to the running direction of the printing material web and convey only this printing material web. The first pull unit whose rotational speed is adjusted is preferably a printing unit of the press unit printing the printing material web.

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 method for automatically controlling the cut-off register in a web-fed rotary press includes determining an expected cut-off error in the area of harps for one of webs or partial webs before the formation of strands and automatically controlling the cut-off register of the one of the webs or partial webs by rotating plate cylinders involved in the printing of the respective web or partial web on the basis of the expected cut-off error thus determined for each web or partial web. The method further includes determining an expected cut-off error in the area of the folder upper section for at least some strands before a complete strand is formed, and automatically controlling the cut-off register by displacement of register rollers located downstream of the former in which the at least some strands are quarter-folded on the basis of the expected cut-off error thus determined for the at least some strands.

Abstract: An apparatus and method for the transport of web-like material, in particular printed webs or packets of printed webs fed from a fold former positioned downstream of a printing machine with a roll that can be driven and against which pressure-application rolls can be adjustably pressed is disclosed.

The first and second rolls are disposed between the first and second end plates and the first end plate is fixed to the carrying framework and the second end plate is removably attached to the carrying framework. The carrying framework is only attached to the only one side wall of the machine frame by the fixed first end plate. A two-stage throwing-on process of the rolls and a two-stage throwing-off process of the rolls is performed.

Abstract: A folding unit upper part assigned to a folder is disclosed. The utility can be widened for the folding unit upper part, having at least two folding formers with associated inlet rolls and pulling groups, by it being possible for at least one element of the folding unit upper part to be varied in accordance with a peripheral parameter.

Abstract: An apparatus and method for combining a plurality of printing material webs to form a multi-layer strand is disclosed. In an apparatus for combining a plurality of printing material webs to form a multi-layer strand, having a wire guide formed by deflection rolls assigned to the individual printing material webs, it is possible to achieve reliable tensioning of the former and top webs and to ensure high accuracy in that the two deflection rolls forming the outlet from the wire guide can be driven.

Abstract: A method and apparatus for operating a printing-press system is disclosed, in which at least one paper web is guided, printed and folded by functional units of the printing press on at least one web path for a printing process. The functional units having at least one paper-inserting mechanism, at least one reel changer, at least one printing unit, and at least one folder apparatus. The functional units which belong to a web path are actuated jointly and different functional units of different web paths are controlled individually.

Abstract: A method for setting the cut register in a web-fed rotary press includes assigning a cut register function to a predetermined speed function, wherein the predetermined speed function describes a time curve of an operating speed of the rotary press starting from a predetermined initial value and the cut register function describes a time curve of the set value of the cut register, and changing the set value of the cut register continuously and synchronously in accordance with the associated cut register function during a variation in the operating speed of the rotary press according to the predetermined speed function, the cut register function being chosen empirically such that it counteracts a change in the actual value of the cut position as a result of the change in the operating speed.

Abstract: A turner bar has an outer surface having a profile shaped for enabling air cushions to be built up between the outer surface and a printed material web which is fed around the turner bar. In addition, or as an alternative, a guide plate or an aerofoil profile may be arranged on the turner bar for creating the air cushion. Air may also be fed from radial holes or from holes in a guide plate to make it easier for the printed material web to slide over the turner bar.

Abstract: Arrangements are described which allow a printing stock web to be reliably drawn through a drier. A draw-in member which grasps the tip of a printing stock web has a power transmission, e.g. a roller chain, which runs in a guide. Plates or blowing boxes which are movable vertically to the draw-in plane of the printing stock web and form closures in the guide by lateral projections of their side walls are provided to prevent dirt from penetrating into this guide. Rollers or cylinders are provided for additional correction of a lateral displacement of the printing stock web while the web is drawn in by the draw-in member. A friction-locking engagement, i.e.
