摘要:
A web-fed rotary printing press includes a printing unit which has a specific width for printing a web with six adjacent vertical printed pages in a first newspaper format. A longitudinal cutting device is used to divide the web into three partial webs, each of which having a width corresponding to two of the newspaper pages. A folding assembly includes a group of three fold formers which are located next to each other on a machine plane. The three formers are disposed in the web-fed rotary press in such a that the two distances between the folding planes of two of the formers, which are placed next to each other in pairs, can be modified.

A printing system includes a first printing machine that is provided in the form of a newspaper printing machine and which comprises at least two first printing units that are provided in the form of printing towers and with a number of printing machines arranged one above the other for effecting double-sided printing of a substrate in multiple colors. A first folding funnel is arranged in a machine exit of these first printing units. A second printing machine is provided with at least one second printing unit and with a dryer that is situated in the machine exit of the second printing unit. The at least one second printing unit is positioned with respect to its printing location, and when viewed from above, is arranged next to the machine exit of the first printing units provided in the form of printing towers. A web, or a partial web, which has been printed by the second printing unit, and which has passed through the dryer, can be diverted by 90° from a direction of conveyance that is perpendicular to a machine exit and can be guided in a direction of conveyance that is parallel to the machine exit.

A printing machine system includes a first printing machine which is configured as a newspaper printing machine and which has at least two first printing units that are structured as printing towers, each with a plurality of superimposed printing groups that are usable for multicolor printing. The first printing machine also includes a first folder structure which is arranged in a machine alignment of the at least two first printing units. A second printing machine has at least one second printing unit and a second folder structure. The first printing units and the at least one second printing unit are arranged in one row. The first printing units, which are configured as printing towers, differ from the at least one second printing unit in at least one of their effective printing length and a circumference of imaging printing group cylinders.

A printing press is comprised of at least one dry offset printing unit. At least two different webs can be fed through the dry offset printing unit. In a first production mode “C” of the printing press, a first web is fed through the dry offset printing unit without a subsequent drying process. In a second production mode “H” of the printing press, a second web is fed through the dry offset printing unit and through an active dryer. In both the first and second production modes “C”, “H”, an inking unit of the printing unit is filled with the same ink.
摘要:
A printing machine system includes a first printing machine which has at least one first printing unit and a first fold forming funnel and that is arranged in the machine alignment of the at least first printing unit. A second printing machine, which has at least one second printing unit, and a second fold forming funnel, is also provided in the printing machine system. The second fold forming funnel is in machine alignment with the at least one second printing unit. The printing group cylinders of the first and second printing units are positioned substantially orthogonally in relationship to each other in their axial directions. The two fold forming funnel structures are positioned substantially orthogonally in respect to each other in a line running in a direction of material web transport as projected onto a horizontal plane.
摘要:
A product section is produced in a printing machine that has at least one former. A web or a partial web of material is guided over the former. At least one web or one partial web is initially guided over a plow fold device and then over one, or another odd number of turning bars. This at least one web or partial web is then united, without passing through the former, and on a side that has been folded in by the plow fold device, over at least one guide roller as a partial strand with a partial strand that was guided over the former as a strand bundle before this partial strand is cut transversely in a transverse cutting direction into product sections.

A printing system is provided with a first printing machine that includes at least one printing unit and a first folding funnel which is located at an exit of the printing unit. A second printing machine, with a second printing unit and a drier, together with a folding funnel at its exit, is also part of the printing system. The first and second folding funnels differ from each other in the number of formers that are placed next to each other in a machine plane, or vary in an effective width of one or more folders. A web, or a partial web, which is printed by the second printing unit, and which is guided through the drier, can be guided either to the second folding funnel structure, or can be guided to the first folding funnel structure, which differs from the second funnel structure in at least one of numbers and width.
摘要:
A printing machine includes at least one printing group, one folder and at least one turn-and-mix stage that supplies the printed web output from the printing group to the folder. A web path from the printing group to the folder, when projected into a horizontal plane, is bent or deviates in the area of the turn-and-mix stage. The turn-and-mix stage or superstructure, includes a horizontal cutting device at an input side, for use in cutting the web into at least two partial webs. At least two horizontally displaceable turning bars are provided, and the partial webs pass around these turning bars.
摘要:
A printing machine is comprised of several printing groups, at least one dryer and at least one folding apparatus. At least two of the printing groups are arranged side by side in the axial direction of the cylinders in the printing groups. A longitudinal direction of the dryer extends perpendicular to the axes of rotation of at least one cylinder group which defines a printing gap.
