Rotary roller printing press

DETAILED DESCRIPTION The object of the present invention is directed to providing a web-fed rotary printing press.
In accordance with the present invention, this object is attained by the provision of a web-fed rotary printing press having at least one, and typically several printing units.
The printing units include one or more cylinder pairs, each consisting of a forme cylinder and a transfer cylinder.
Those cylinders are sized to print six newspaper pages arranged axially along the length of each cylinder.
The advantages to be gained by the present invention rest, in particular, in that a simple, cost-effective and space-saving construction, together with the provision of a high variability of the product or intermediate product, is made possible.
Advantages also lie, in particular, in that, in comparison to double-width printing presses, the production dependability is considerably increased with the same target size of a product.
Also, when retaining the number of printing units, the yield of the printing press, or of each printing group, can be increased by 50%.
The number of roll changers, and their associated investment costs, the frequency of roll changes and the resultant loss of production dependability, as well as the set-up time when drawing in webs and the increase in cycle times, can all be reduced for the same production size in comparison with a double-width printing press.
In an advantageous embodiment, the printing units are structured as nine-cylinder satellite printing units, which results in high precision of the ink register, and otherwise in a low-oscillation construction.
Oscillations are also reduced by the advantageous arrangement, structure and fastening of dressings on the cylinders.
For one, openings on the shell surface in the circumferential direction are minimized.
It is furthermore also possible to arrange the openings, at least on the transfer cylinder, alternatingly offset in the circumferential direction, in such a way, that a closed shell surface always works together with the forme or satellite cylinder, at least over the length of a section of the forme or satellite cylinder
