Definitions

the invention relates to printing cylinders with multiple diameters and elevators arranged on the lateral surface for carrying a sheet on its already printed side for sheet-fed offset printing machines for perfecting.
Double-size printing cylinders with a chrome-plated and ground outer surface are known. Due to the accumulating form errors of the two halves of the polished cylinder, duplication phenomena and the redistribution of the already printed ink in the reverse printing easily occur during operation, so that the printing cylinder has to be washed more frequently and the environmentally harmful solvent consumption increases. This leads to a negative influence on quality.
the invention solves this problem by means of the training features according to claim 1.
a number of foils with different thicknesses and possibly different shapes are assigned to the printing cylinder for selection, so that the runout errors or the sum of the shape errors of the two halves of the printing cylinder of a double-sized printing cylinder are compensated for by the selection of a suitable foil.
films can be ground non-parallel by shifting the center of the grinding device so that the surfaces of the film run non-parallel to each other in the circumferential direction, thereby achieving a difference in thickness between the front edge and the rear edge of the film in the direction of sheet travel.
Such foils are assigned to the printing cylinder in stages, for example sorted in three stages of 0.01 mm each.
the printing cylinder can be brought into a new condition at any time by changing the foil by changing the foil.
damage during production The appropriate grinding techniques for the back of the film are already mastered by relevant companies. The same applies to corresponding measuring devices with which the entire format can be detected, so that the pre-sorting of the foils with it can be done.
foils for purposes of the invention can also be produced from a carrier layer with a high modulus of elasticity and a chrome layer, which gives the structured surface from which the sheet is carried.
these foils can also have a non-parallel course of the surfaces to one another according to the illustration in FIG. 2, so that the front edge 7 has, for example, a greater thickness than the rear edge 8.
a non-parallel course of the surfaces 9 and 10 relative to one another can also lead to a difference in thickness between the drive side and the operator side.
FIG. 3 shows the fundamentally simplified structure of a device for processing a film intended for the purpose according to the invention. It consists of a grinding cylinder 1, which is mounted rotatably about an axis 2 in a frame 3 and has clamping means for a film 4 to be processed on its outer circumference. A driven grinding wheel 5 is effective against this film 4, the axis 6 of which is aligned parallel to the axis 2. To achieve a non-parallel surface profile on the film 4 in the circumferential direction, the axis 2 of the bearing of the grinding cylinder 1 is displaced in the direction 2a along the axis 6 of the grinding wheel 5 in the common plane of the two axes 2 and 6.
the parallel position of the two axes 2 and 6 can optionally be changed at an angle to one another in order to achieve different thicknesses of the film on the drive side and on the operator side, for example in the case of conically ground cylinders.
the film itself can consist, in a manner known per se, of a carrier layer and of a cover layer which has the structured surface to avoid the accumulation and build-up of color in the counterprint.
