Printing-press arrangement
An arrangement includes at least two web-fed rotary presses, wherein each of the at least two web-fed rotary presses includes a roll-changer unit with a plurality of roll changers, a printing unit with a plurality of press-unit towers, a turner-bar unit with a plurality of turner bars, and a folder unit with at least one folder superstructure and at least one folding unit. The units are arranged one behind the other in the axial direction of the respective web-fed rotary press. The web-fed rotary presses are arranged at a minimum axial distance from one another, and at least two of the roll changers of each of the roll-changer units are positioned above one another.
1 . An arrangement comprising at least two web-fed rotary presses, wherein each of said at least two web-fed rotary presses includes a roll-changer unit with a plurality of roll changers, a printing unit with a plurality of press-unit towers, a turner-bar unit with a plurality of turner bars, and a folder unit with at least one folder superstructure and at least one folding unit, said roll changer units, printing units, turner-bar units, and folder units being arranged one behind the other in an axial direction of the respective web-fed rotary press, wherein said at least two web-fed rotary presses are arranged at a minimum axial distance from one another and at least two of said roll changers of each of said roll-changer units are positioned above one another.
2 . The arrangement of claim 1 , wherein two immediately adjacent web-fed rotary presses of said at least two web-fed rotary presses are oriented substantially parallel to one another such that operating sides of said press-unit towers of said printing units of said two web-fed rotary presses lie opposite one another, thereby defining a common operating space therebetween.
3 . The arrangement of claim 1 , wherein two immediately adjacent web-fed rotary presses of said at least two web-fed rotary presses are oriented substantially parallel to one another such that drive sides of said press-unit towers of said printing units of said two web-fed rotary presses lie opposite one another, thereby providing a circumferential operating space around said printing units of said two web-fed rotary presses.
4 . The arrangement of claim 1 , wherein two immediately adjacent web-fed rotary presses of said at least two web-fed rotary presses are oriented substantially parallel to one another such that a drive side of said press-unit towers of said printing unit of a first one of said two web-fed rotary presses lies opposite an operating side of said press-unit towers of said printing unit of a second one of said two web-fed rotary presses.
5 . The arrangement of claim 1 , wherein the axial distance between said web-fed rotary presses is adapted to a production of a common printed product such that a printing material which has been printed and optionally pre-folded in said printing unit of a first one of said at least two web-fed rotary presses is fed entirely or partially to an adjacent second one of said at least two web-fed rotary presses, thereby ensuring sectional flexibility of the printed product or page flexibility of the sections of the printed product.
6 . The arrangement of claim 5 , wherein a printed, non-folded and accordingly web-shaped printing material is fed entirely or partially from a turner-bar unit of a first one of said at least two web-fed rotary presses to a turner-bar unit of an adjacent second one of said at least two web-fed rotary presses, thereby ensuring page flexibility of the sections of the printed product.
7 . The arrangement of claim 5 , wherein a printed printing material which has been pre-folded in a folder superstructure of said folder unit of said first one of said at least two web-fed rotary press and is accordingly stream-shaped is fed to a folding unit of said folder unit of said adjacent second one of said at least two web-fed rotary presses, thereby ensuring sectional flexibility of the printed product.
8 . The arrangement of claim 1 , wherein two immediately adjacent ones of said at least two web-fed rotary presses are configured identically such that web-shaped printing materials are printed with an identical number of printed pages in each of said adjacent ones of said at least two web-fed rotary presses.
9 . The arrangement of claim 1 , wherein two immediately adjacent ones of said at least two web-fed rotary presses are configured differently such that web-shaped printing materials are printed with a different number of printed pages in each of said adjacent ones of said at least two web-fed rotary presses.
10 . The arrangement of claim 9 , wherein press units of said press-unit towers of said adjacent ones of said at least two web-fed rotary presses are configured differently such that a different number of printed pages is printed in the circumferential direction or in the longitudinal direction of corresponding impression cylinders.
