Abstract

For an impression cylinder with multiple diameter and lifts arranged on its outer surface for carrying a sheet on its side which has already been printed for sheet-fed offset printing machines for perfecting, there is provided at least in the region of a surface carrying a sheet a foil which is adapted to dimensional errors of the impression cylinder, compensates said dimensional errors, has a structured surface for the sheet rest and is attached in an exchangeable manner to the outer surface of the impression cylinder.

Description

Imprrssion cylinders with varied diameter
The present invention relates to the impression cylinder of many times of diameters on a kind of sheet-fed offset press that is used for printing positive and negative and the overlay coating that is used to support the paper face that had printed on its outer surface is set.
The double size impression cylinder of outer surface chromium plating and process polishing is known.In use, because the influence of the form error that accumulation is got up on the polished surface of two half cylinders, the phenomenon that printing surface can occur bluring, and greasepaint out of the press is shifted, therefore need frequent washing barrel surface, increase the consumption that environment is had the wash solution of adverse effect.These situations have adverse influence for quality.
Process sandblast earlier in addition, and then the double size impression cylinder of chromium plating also is known.The surface ratio of this class cylinder is more coarse; and because cylinder is to be combined by two semicylinders inequality; difference between them can cause that also printing surface is fuzzy; by the time some abrasion of cylinder surface; just need to change whole cylinder, thereby cause the expenditure of material and labour cost and shut down the loss of overhauling.
24 46 No. 188 disclosed impression cylinders of German patent DE-PS are single diameters, cover the nickel foil that one deck has superficial makings above it, the height that this nickel foil is divided into supporting paper with cylinder surface is appeared and recessed two zones of supporting paper not, thereby reduces the deposition of greasepaint on outer surface of cylinder on the just printed printed sheet.The nickel foil that is used for this purpose is seen German patent document DE-OS No. 2916505.
The objective of the invention is to guarantee can obtain high-quality when using the impression cylinder of many times of diameters, greasepaint can not be deposited on the outer surface of cylinder when carrying out printed on both sides, thereby minimizingization is taken the time on washing barrel and the consumption of cleaning solution.
This purpose is finished by following measure, promptly in the scope of wanting supporting paper on the outer surface of cylinder at least, fixing a surface have texture in order to support the paper tinsel of described paper, this paper tinsel can be adjusted and compensate the form error of cylinder surface and can change.
This cylinder can be equipped with paper tinsel that many thickness do not wait for selecting for use, these paper tinsels also can have different shapes in case of necessity, can select suitable paper tinsel for use according to the out-of-roundness of cylinder surface or according to the form error of the stack of the two halves of double size cylinder, thereby these errors are compensated.
When needing, also might grind to form wittingly and to be not parallel to each other two surfaces of these paper tinsels, this is by the off-centring of lapping device is arranged, thereby the surface of paper tinsel is not parallel to each other on the direction of circumference, and the forward position thickness that makes paper tinsel on the direction of conveyance of sheets is back along thickness difference to some extent with paper tinsel.Such paper tinsel can become the state of classification to be installed on the impression cylinder, for example is divided into three grades, and every grade of thickness difference is 0.01 millimeter.By a fixing mark,, can make cylinder be in new state by changing a new paper tinsel whenever in shape difference or cylinder surface when abrasion are arranged appears in the two halves of finding impression cylinder.Equally, also can be changed when running into surface damage in running, the technology that the back side of paper tinsel is accurately polished is provided by the specialized company in this field.Same, the means that paper size is measured also are known, so that chosen in advance will be adorned the paper tinsel of usefulness.
Copy the paper tinsel that is used for single diameter impression cylinder, paper tinsel used in the present invention can adopt a basic paper tinsel with high resiliency modulus, covers the chromium layer that is used for supporting paper that one deck has grain surface above.
Accompanying drawing shows the embodiment that is used for paper tinsel of the present invention of two kinds of nots to scale (NTS), also shows the principle of the device of processing paper tinsel.
These accompanying drawings are:
Fig. 1 shows a kind of partial sectional view of paper tinsel, and its two surfaces are parallel to each other, and this figure is that not to scale (NTS) is drawn;
Fig. 2 shows a kind of partial sectional view of paper tinsel, and its two surfaces are uneven, and this figure is that not to scale (NTS) is drawn as Fig. 1;
Fig. 3 shows a side view that is used to process the device of paper tinsel illustrated in figures 1 and 2.
In order to compensate out-of-roundness that stacks up and/or the profile error on the two halves that are present in the double size impression cylinder, according to measuring and the mark of being done to this cylinder is corresponding, load onto the paper tinsel of the different-thickness of several formation steps in the scope of supporting paper, for example using corresponding to thickness shown in Figure 1 is 0.3,0.29 and 0.28 millimeter several paper tinsels.
For off-centring is compensated, these paper tinsels also can have as uneven surface shown in Figure 2, and for example its forward position 7 is thicker slightly along 8 more thereafter.
Correspondingly, the surface 9 and 10 that is not parallel to each other also can make paper tinsel have thickness difference between the driving side of printing machine and fore side.
Fig. 3 shows a device that is used to process the used paper tinsel of the present invention of having simplified, and it comprises an abrasive roller 1 that is contained on the support 3, and this cylinder can rotate around axle 2, have for installing on the outer surface of cylinder and fixes the device of paper tinsel to be processed 4.A driven emery wheel 5 is contained on the axle 6 that is parallel to axle 2, emery wheel plays a part to grind paper tinsel 4, in order to obtain having the paper tinsel 4 of circumferential unparalleled surface, the axle 2 of the bearing of abrasive roller 1 is displaced to the 2a place of the common plane of 6 two axis of axle that are positioned at axle 2 and emery wheel 5.
In addition, during as needs, also can change the angle that is originally 6 on parallel axle 2 and axle, so that obtain the paper tinsel that driving side and fore side at printing machine have different-thickness, for example when on the cylinder that is used to grind to form taper.
This paper tinsel can be in the known manner be made of basic paper tinsel and a superficial layer that has texture of a supporting usefulness, and this surface can avoid being stained with of greasepaint long-pending when the two-sided printed sheet of printing.
