Abstract: A former arrangement for a rotary printing press is disclosed. The former arrangement includes a former arrangement module with a base element which is mountable on a stationary element of the rotary printing press. A former is connected to the base element. A first web lead device provides for guidance, on the former entry side, of a printing substrate web to be directed in the case of operation over the former. A second web lead device provides for guidance, on the former exit side, of the printing substrate web. The former rests on a cantilevered support element which is fastened with a first end to the base element and which extends cantilevered transverse to a web feed direction over the former.

Abstract: A turner bar for a rotary press for deflecting a substrate web in two web running directions is acted upon by pressurized air. The turner bar includes at least one inner tube and one outer tube, which have air discharge holes assigned to one another to produce an air cushion above the turner bar. The inner tube can be adjusted relative to the outer tube, so that the air discharge holes can be closed in such a way that the air cushion is adapted to the margins of the substrate web. It is thus possible to use the turner bar in both web running directions.

Abstract: An apparatus and method for reversing a print material web is disclosed. A reversing bar unit includes a frame and a reversing bar pivotably mounted on the frame at a pivot point. The reversing bar includes an outer tube and an inner tube. A first end of the coupling element is coupled to the inner tube and a second end of the coupling element is moveably coupled to the frame at a distance from the pivot point. Upon a pivoting of the reversing bar the coupling element translationally or rotationally moves the inner tube relative to the outer tube.

Abstract: A functional unit for a rotary printing press and a rotary printing press having such a functional unit is disclosed. The functional unit has an assembly unit to receive at least one component of the functional unit, in which the assembly unit has at least one assembly section, at least one assembly opening that is formed in the assembly section and in which the at least one component is received, and a support section on which a weight load is supportable. A component-free opening that in one cross-sectional dimension is at least as large as one cross-sectional dimension of the assembly opening is provided in the assembly section between the support section and the at least one assembly opening. Pre-stresses induced by the weight load on a bearing element are thereby inexpensively reduced or avoided for the component.

Abstract: A longitudinal folding apparatus for webs on a folder of a rotary press includes a variable-position folding former arranged behind a former roll and ahead of folding rolls in the web running direction, it being possible to adjust the folding former approximately in parallel in the direction of longitudinal axes of the folding rolls. The folding former is connected in a hinged fashion to levers which are mounted pivotably in the frame, the levers being drive-connected to one another.

Abstract: In a turner bar unit having turner bars arranged one above another in a plurality of planes, unscrewed webs of a web printing material can be inserted into the turner bar unit from the sides, in a plurality of planes arranged one above another on each side. The webs of the web printing material can be divided into part webs at cutting devices arranged upstream of the turner bars in the insertion direction of the printing material on each side, and the part webs can be deflected or turned at the turner bars in such a way that the part webs can exit the turner bar unit at right angles to the insertion direction of the printing material.

The folding former is connected in a hinged fashion to levers which are mounted nivotably in the frame, the levers being drive-connected to one another.

Abstract: An offset printing unit includes at least one cylinder pair with a form cylinder and a transfer cylinder. The transfer cylinder cooperates with an impression cylinder in such a way that ink can be applied to a printing material web guided between the transfer cylinder and the impression cylinder. In order to permit the economic production of multifarious products with a relatively low technical outlay, the form cylinder is fitted in the circumferential direction with one, and in the longitudinal direction with at least four, portrait printed pages in broadsheet format. The form cylinder may optionally be fitted with landscape printed pages in tabloid format or portrait or landscape printed pages in book format. A circumference of the form cylinder receives one flexible printing plate and a longitudinal length of the form cylinder receives at least one flexible printing plate.
