Definitions
- the present invention relates to a device for wet film application in printing units of rotary printing machines, with a hollow dampening roller with a porous roll wall, wherein the roller cavity is filled with a pressurized liquid.
- Such a device has become known, for example, from JP 05084893 A.
- JP 05084893 A discloses hollow rolls with a porous roll wall as an ink or water reservoir in order to bring liquids from the roll cavity through the porous roll wall to the outside as moist application onto the roll outer surface.
- Fig. 3 shows another known apparatus 100 for wet film application with a fountain solution box 101, a dampening roller (Feuchtduktor) 102 and a scoop roller 103 to supply the dampening form roller 102 dampening water from the fountain solution box 101.
- the dampening water circulates continuously in a line system 104 in a circle and is provided with a dampening agent metering 105 with fountain solution additives, cooled by a cooling system 106 and mixed for even better crosslinking with alcohol.
- the cooling is needed primarily to reduce the evaporation of the alcohol and other volatiles.
- the circulating fountain solution is constantly enriched with powder, dye and paper particles 30.
- This object is achieved in that on the inside of the porous roll wall, a membrane is provided, whose pores are smaller than the pores of the porous roll wall.
- the roll wall with its larger pores serves as a carrier for the finely porous membrane.
- the mechanical stability of the dampening applicator roll is achieved via the roll wall and the filter property via the thinner membrane, which still allows a sufficiently high throughput due to its small wall thickness.
- the pores of the membrane are preferably less than about 0.5 microns and more preferably less than 0.1 microns, preferably less than 0.05 microns.
- the pore size of the porous roll wall is preferably at least about 0.5 .mu.m and is more preferably between 0.5 .mu.m and 5 .mu.m.
- the dampening roller is made of porous sintered material, preferably of porous sintered metal, and the membrane a plastic membrane, gas membrane, ceramic membrane, metal membrane or a polymer membrane.
- the dampening roller on a leading out of the roller cavity drain which is either permanently open or up and zuu Kunststoffbar.
- Fig. 1 shows the device according to the invention for the wet film application in
- FIG. 2 is a sectional view of the dampening applicator roll shown in FIG. 1;
- Fig. 3 shows a known device for the wet film application.
- the apparatus 1 shown in Fig. 1 for the wet film application in printing units of rotary printing machines has a hollow dampening roller 2 with porous roller wall 3, on the inside of a membrane 4 is provided.
- the membrane 4 is a plastic membrane of polysulfone with a wall thickness of 0.8 mm and a pore size of about 0.3 microns
- the dampening roller 2 is made of highly porous sintered material of 1, 4404 stainless steel with a wall thickness of 8 mm and with a pore size of 0.5 ⁇ m.
- the roller cavity 5 is connected to a fresh water connection 6 via a supply line 7 with pressure and overflow 8, which controls the amount and pressure of the supplied fresh water.
- the temporarily needed overflow is controlled by two arranged in front of and behind the dampening roller 2 control slide 9.
- a dosing pump 10 doses the dampening solution required for printing to the fresh water.
- the flow of fluid from the roller cavity 5 controlling the control slide (drain) 9 is either permanently open or up and zuu Kunststoffbar.
- the dampening water mixture exits the roll cavity 5 through the pores of the membrane 4 and the roll wall 3 radially outward, as indicated by the flow arrow 11.
- the dampening roller 2 transfers the dampening solution directly to the plate cylinder or into the inking unit (depending on the desired arrangement).
- the mechanical stability of the dampening form roller 2 is achieved via the roll wall 3 and its filter property on the thinner membrane 4, which still allows a sufficiently high throughput of the dampening solution due to their small wall thickness.
- the membrane 4 of the dampening roller 2 the fountain solution can be dispensed finely dosed to the outside. Due to the direct dampening water entry into the printing unit, the fountain solution does not have to be constantly circulated, which means that there is no soiling of the dampening solution.
- the dampening water, which is printed with alcoholless, should be very pure, which is achieved with the fountain roller 2, since depending on the choice of the membrane 4, the water is additionally cleaned. Even if alcohol is to be used for printing, the entry with the dampening roller 2 has the advantage that the alcohol does not have to be cooled and hardly evaporated by the direct entry and thus in very small amounts highest crosslinking and hardly produces emissions.
