Method for the production of a printed product, processing device, and system for the production of printed products
A printing system is used for printing newspapers or for job printing and includes a web-fed press, including an unreeling stand, and one or more printing units for printing a web that is unrolled from a roll at the unreeling stand. A re-rolling stand may be used to wind up the web, after it has passed through the printing units. A separating device forms a second part of the printing system and includes an unreeling stand which can receive a roll of a printed web. The printed web can be unrolled and can be directed to a subassembly from this re-rolling stand. In the subassembly, the further processing of the web can take place at a different time and place, and at a different speed than the original printing of the web.
1. A processing device of a web-fed printing press comprising:
at least first and second unreeling devices adapted to unwind previously imprinted, and rewound at least first and second webs of material;
a separate position-controlled electric drive mechanism for each of said at least first and second unreeling device
a control device adapted to control each said separate position-controlled electric drive mechanism for each of said at least first and second unreeling devices to maintain registration of said at least first and second, previously imprinted and rewound webs of material as said at least first and second previously imprinted and rewound webs of material are unwound by said at least first and second unreeling devices;
a draw-in unit arranged downstream, in a direction of web travel, of each of said at least first and second unreeling devices;
a longitudinal web cutting device arranged directly after each said draw-in unit in said direction of web travel and usable to selectively cut each of said at least first and second webs of material into partial webs;
a turning bar arrangement located after each said longitudinal web cutting device and adapted to mix said partial webs; and
at least one former, at least one transverse cutting device and at least one transverse folder after each said turning bar arrangement and each adapted to produce a printed product put together from said registered, previously imprinted and rewound webs of material which have been unwound from said at least first and second unreeling devices by said separate position-controlled electric drive mechanisms for each of said at least first and second unreeling devices and selectively cut into said partial webs.
2. The processing device of claim 1 wherein said at least one former is centered on an uncut one of said unwound, previously imprinted, rewound webs of material web, and a second former, said second former being centered on one of said partial unwound, previously imprinted, rewound webs of material cut by said longitudinal web cutting device.
3. The processing device of claim 1 wherein said web-fed printing press is a 16-page printing press.
4. The processing device of claim 1 wherein said printed product produced from said unwound, previously imprinted, rewound webs has 32 pages.
5. The processing device of claim 1 wherein said web-fed printing press is a jobbing printing press.
