Definitions

the invention relates to a device for supplying liquid to the plate cylinder of an offset rotary printing press according to the preamble of claim 1.
Such a device is known from a research report No. 3.216 "Dampening unit examination" by the Federal Printing Association or the German Research Association for Printing and Reproduction Technology (FOGRA) page 30, Figure 38.
the additional applicator roller is not attached directly to the ink rubbing cylinder, but in order to make the contact of the further applicator roller carrying the dampening solution with the inking cylinder of the inking unit, two additional oleophilic intermediate rollers are attached between the additional applicator roller and the distribution cylinder.
both ink and dampening liquid are applied to the plate cylinder via the additional applicator roller.
Such a way of working is well suited for a number of printing jobs, especially if the subject is not prone to ghosting or stenciling, e.g. is heavily covered.
the object of the invention is to switch off one of the intermediate rollers, linked to the machine control, from the ink supply and / or fountain solution supply.
the advantage of the invention is that with the second setting of the intermediate rollers 3; 4 With dampening system separated from the inking unit, subjects which are prone to ghosting or stenciling, for example are lean, can be printed with good success using the generic device. Depending on the separation point, at least one gap point is retained in the inking unit or in the dampening unit for storing ink or dampening solution.
the device comprises a plate cylinder 1 which is supported by means of pins at both ends in side walls 13 of the printing press.
the pins are driven from the main drive of the machine in a manner known per se, not shown in detail, by gearwheels arranged outside the one side wall 13.
a water box is provided for supplying the dampening liquid, in which a water box roller 5 is partially immersed.
the strength of the dampening liquid is adjusted by means of a metering roller 6.
the film dampening unit 2, 5, 6 thus guides the dampening liquid directly onto the pressure plate of the plate cylinder 1 and in a very short way, so that the dampening solution evaporation is kept low.
the drive and adjustment of the dampening unit rollers to one another is known and is therefore not explained in more detail.
the second oleophilic intermediate roller 4 can be moved into a second switching position, the intermediate roller 4 being supported on both sides at one end of a carrying lever 9 which is pivotally mounted about the axis 11 in the side walls 13.
a working cylinder 10 controlled by the machine control 14, e.g. a pneumatic or a hydraulic cylinder articulated, which is also pivotable about an axis 12 fixed to the frame.
the intermediate rollers 3, 4 are connected in a known manner as connecting rollers between the inking and dampening units, in the second switching position they are separated in a previously unknown manner, so that e.g. the intermediate roller 3 also serves as an additional rider roller in order to compensate for the excess dampening solution due to plate cylinder channel reactions, which improves the printing result.
the two intermediate rollers 3, 4 are mounted on the arms of a double lever 9 (FIG. 2) which can be pivoted about the axis of the ink distribution cylinder 8 by means of a working cylinder 10 in order to separate the wet inking unit.
a double lever 9 FIG. 2
the intermediate rollers 3, 4 of the inking unit are retained as storage rollers as well as nip and possibly rubbing points.
the first intermediate roller 3 can be provided with a known drive mechanism which effects an axial reciprocating movement.
a drive is not shown in the drawing, but it is easy to imagine that it is provided in a known manner.
the storage of the intermediate rollers 3, 4 in the support lever 9 can be selected so that e.g. whose pegs are received via a known roller lock and the intermediate rollers are thus portable.
the invention is not restricted to the above two exemplary embodiments.
