Description

Koenig & Bauer - 1 - 1979-07-20 Public company P1.531DE Wuerzburg / Germany 326 / Ru / vRf Printing unit for offset web-fed rotary printing machines

The invention relates to a printing unit for five and more colors for an offset web press according to the umbrella term of claim 1.

Such printing units are, for example, nine-cylinder printing units - also satellite printing units called - became known (DE-AS 23 37 259). Ten-cylinder satellite printing units are also known. Multi-cylinder printing units can be stacked or are placed next to each other and produce multi-color prints when converging, whereby paper web transfers are necessary when printing units are placed next to each other.

Nine and ten-cylinder printing units have the disadvantage that they have to be "totally" reversible, i.e. they eat into it ■ measure numerous reversing devices and Devices for changing the position of printing and blanket cylinders are available. These facilities and devices are very expensive. Another disadvantage of both types of printing units is that, for example, with 4/1 or 4/2 printing - The numerator indicates the number of colors printed in reverse printing, and the denominator indicates the number of colors printed in the back print - the paper web to be printed on in this way a relatively long way from a first printing unit must be transferred to a second.

When using e.g. ten-cylinder printing units with a 4/1 or 4/2 print, 2 χ 2/0 = 4/0 is first printed in the first printing unit and then in the remaining 0/1 or O / 2 colors of the second printing unit. During this printing process, ^ it is already in the 2-fold printing on the paper web 4/0 printing inevitable printed on one or both impression cylinders, which can lead to the dreaded doubling.

Another disadvantage is ten-cylinder printing units in that when transferring to 4/1 or 4/2 printing once or twice the upper printing units each involved printing unit must be "wrapped". For setup (placing or washing of plates) the Paper web torn or torn off or adjusted using relatively cumbersome driving mechanisms (DE-OS 27 41 596), that it is possible to work on the upper printing units of the printing unit.

The nine-cylinder printing units have similar disadvantages on, but here the 4 / O pressure is generated in the first printing unit with 1 χ 4 / O, and then to generate a 4/1 or 4/2 print after the transfer in the case of the second printing unit involved for one-color or two-color generation of the reverse print only one Impression cylinder is involved, so the risk of doubling is only half as great as with ten-cylinder printing units.

"Wrapped * printing units can with nine-cylinder printing units mostly avoided.
