- each form cylinder 02 is provided with an up / down plate aid designed as a plate changer or semi-automatic machine 42, which permits a rapid and less labor-intensive production change.
- FIG. 09 Also indicated (exemplary in the upper double printing unit) is the formation of a pressure-Ab / -An-sites enabling storage of at least three of the four, in particular all printing cylinder 02; 03, in linear bearing units 43, which allows the radial movement required for the bodies.
- FIG. 09 For the sake of clarity, not all of the rollers comparable to FIG. 1 were shown in FIG. 09; 1 1; 13; 14; 16; 17; 18 of the inking unit 06 and rollers 21; 22; 23 of the dampening unit 07 referred to, as they correspond recognizable in the roll scheme. Also with regard to the
- Fig. 4 shows a schematic representation of printing units 01 with dampening units 07 according to the above-described embodiments in a four pairs as
- the dyeing and dampening 06; 07 correspond in their roller scheme - possibly up to small spatial peculiarities - substantially to that described with reference to FIGS. 1 and 2. Therefore, not all comparable to Fig. 1 rollers 08; 09; 1 1; 13; 14; 16; 17; 18 of the inking unit 06 and rollers 21; 22; 23 of the dampening unit 07 denotes.
- the dampening units 07 are here also preferably each pre-moistening arranged in the printing units 01 of the printing unit 46. Unlike the "linear" Double printing units from FIG.
- the dampening units 07 are arranged in the printing unit 46 in such a way that the dampening form roller 21 of the dampening unit 07, which is operatable from the outside, faces one of the closest outer side of the forme cylinder 02, and the dampening form roller 21 of the dampening units 07, which can be operated from the inside, interacts with a side of the forme cylinder 02 facing the outer side, the "outer side” being that side of the printing unit 01 which, in the longitudinal direction of the printing unit cylinders 02; 03 (04) runs, d. H.
- z. B. H-pressure unit 47 is the Fig. 4 mentioned to apply to differences in the design of the inking unit 06 concerned.
- the inking unit 06 is formed here of the type of einwirkigen film inking unit 06, that is, two distribution cylinders 17; 18 are here in the color flow or Compactor arranged serially. With the forme cylinder 02 and / or the cylinder near the cylinder 17 act two inking rollers 08; 09 together, but as shown in Fig. 1 and 2, preferably the dampening roller 21 with the dampening unit next inking roller 08 in the manner outlined above are brought into contact with each other and / or a sequence or sequence in the dampening roller is changeable.
- FIG. 6 is an example of the arrangement and execution of printing units 01 with dampening units 07 according to the embodiment in a four printing units 01 having execution of a running as a satellite printing unit 48 printing unit 48 is shown schematically.
- four printing units 01 are arranged around a common satellite cylinder 04, in the case of a ten-cylinder satellite printing unit not shown four printing couples 01 pairs of two satellite cylinders 04, with which or which they in print-four
- the dampening units 07 described with reference to FIGS. 1 and 2 cooperate, wherein at least one roller, in particular the dampening form roller 21, can be changed over in the aforementioned manner for the washing operation.
- the dampening roller 21 with the dampening unit next inking roller 08 in the manner outlined above can be brought into contact with each other and / or changed in the (series) sequence in the dampening unit roller train.
- two diametrically opposed dampening units 07 are pre-moistening, and the other two opposite dampening units 07
- Reibzylindern 22 at least the Reibzylindern 22 of the moistening dampening 07, (here right below and top left) each have a second z. B. as a rider roll 49th
- the inking units 06 can basically be of any type, but with zone-adjustable film dampening units, in particular with at least two
- Friction cylinders 17; 18 are preferable.
- the inking unit 06 shown here corresponds with respect.
- the roll scheme for reasons of space advantageously substantially that of the printing unit 47 of FIG. 5, wherein also an inking unit 06 according to Fig. 1, 2 or 4 can be used.
- the dampening units 07 of all four printing units 01 are pre-moistened, for example by one of the upper and one lower printing units 01, in particular the former diametrically opposite printing unit 01, from an outer side of the printing unit 46 , And the dampening units 07 of the other two printing units 01 of a frame provided in the middle approximately access 51 -. B.
- the dampening units 07 - comparable to those set forth in Fig. 4 - also arranged here in the nine-cylinder pressure unit that the dampening roller 21 of the externally operable dampeners 07 with one of the nearest Druckisersau hseite facing side of the forme cylinder 02, and the dampening roller 21 of the internally operable dampeners 07 with one of the more distant Au hseite and / or the access side facing the forme cylinder 02 cooperates.
