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 called satellite printing units - became known (DE-AS 23 37 259). Also are Ten-cylinder satellite printing units known. Multi-cylinder printing units can be placed one above the other or next to each other and generate them together Multi-color printing, with printing units placed side by side Paper web overpasses are necessary.

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

If, for example, ten-cylinder printing units are used for 4/1 or 4/2 printing, 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, the one already in the 2-fold printing on the paper web 4/0 printing inevitably on one or both of the impression cylinders printed, which can lead to the dreaded doubling.

Another disadvantage is ten-cylinder printing units in the fact that with the transfer to the 4/1 or 4/2 printing once or twice the upper printing units of each printing unit involved must be "wrapped". For setup (placing or washing of plates) the Paper web torn or torn or adjusted via 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 also have similar disadvantages on, but here the 4/0 pressure is generated in the first printing unit with 1 χ 4/0, and then for generating a 4/1 or 4/2 print after the transfer at the second printing unit involved one or two-tone generation of the back print only one impression cylinder is involved, hence the risk of Doubling is only half the size of ten-cylinder printing units.

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

Schoen- and verse print passport changes as a result of machine speed changes cannot occur because the back print is always printed in direct counter pressure to the reverse print, and it therefore there are no long paper web guides.

In the case of the twelve-cylinder printing unit 3, there are both the basic printing unit 4 and the first floor printing unit 6 is the same as the basic printing unit 4 or the Floor printing unit 6 of the fourteen-cylinder printing unit 2. Accordingly, what has been described above applies to them.

On the first floor printing unit 6 of the twelve-cylinder printing unit 3, a second storey printing unit 8 is placed, which consists of a plate cylinder 24 and a blanket cylinder 25. The blanket cylinder 25 is in operative contact with one of the blanket cylinders 18 of the first storey printing unit 6. That is, the blanket cylinder 18 forms a printing point with the impression cylinder 25, through which the paper web 5 is guided. The blanket cylinder 25 is attached to the blanket cylinder with known devices 18 arranged on and off.

The storey printing unit 6 leaves the color guidance options 0/0, 1/1 to, the storey printing unit 8 depending on which of the two rubber cylinders 18 of the Blanket cylinder 25 is in operative contact - the ink guide possibilities O / O, 1/0 or 0/0, 0/1.

To drive the printing units 4, 6, 7 of the fourteen-cylinder printing unit 2 or the printing units 4, 6, 8 of the twelve-cylinder printing unit 3 are standing waves 26 and 27, or 26 or 27 are arranged. you will be
