Definitions
- the invention relates to a blanket cylinder according to the preamble of Claim 1.
- the change in position as a result of a deflection changes the pressure supply, i.e. the contact pressure between those working together in the printing unit Printing cylinder that becomes uneven across the cylinder width. determined in terms of value, this pressure provision is usually determined by measuring the so-called impression width, i.e. the width of the zone that is at each other employed, i.e. cylinders pressed on the contact area of the Cylinder defined. This measurement is particularly easy with offset printing, because here always a cylinder of a pair of cylinders has a compressible (soft) surface having.
- a thickness profile varies in that the The lateral surface in the axial direction of the cylinder has a convex or concave shape the blanket cylinder assumes. That is, it becomes concave in particular ground rubber blankets / rubber sleeves and kankav ground Cylinder surfaces in connection with flat rubber blankets / rubber sleeves described.
- EP 0 704 301 B1 describes a thin one Intermediate layer for adjustment and better anchoring of a rubber blanket a blanket cylinder in the form of a self-adhesive plastic film.
- To the surface of the blanket cylinder has a corresponding to the thickness of the thin film a stepped area in the form of a diameter reduction on.
- This measure can be applied to both fissile and fissile ones Rubber sleeves can be applied.
- Fig. 1 shows a blanket cylinder 1 with a concavely ground Cylinder surface 2, for which a flat rubber blanket can be used, the such a concave surface profile is forced so that the side Ends of the surface of the rubber blanket radially further from the axis of rotation of itself underlying blanket cylinder 1 are removed as the center of the Rubber blanket.
- the resulting surface speed profile improves the conveying behavior with regard to a paper web and avoids Wrinkling. Nevertheless, the grinding process on the blanket cylinder is complex.
- Fig. 2 shows a blanket cylinder 3 according to the invention with a parallel to the axis of rotation offset surface area 4 in the form of a constant diameter reduction.
- this surface area 4 is one at least on the outside concave film 5 inserted, the Surface area 4 completely filled and the outer surface of the Blanket cylinder 3 indirectly a concave to the center symmetrical Gives shape.
- the concave film 5 can be a self-adhesive plastic film that is easily interchangeable.
- the film 5 can, of course, itself as interchangeable Be formed sleeve.
- the film 5 helps on the one hand the rubber blanket (with channels or as a sleeve) to adjust on the cylinder and on the other hand an optimal To offer liability on the roll core.
- Fig. 3 shows a blanket cylinder 6 according to FIG. 2, but one has stepped surface area 7, which is symmetrical concave to the center is sanded. In this surface area 7 there can be a plane or likewise concave film 8 are introduced.

Claims (2)
- Gummituchzylinder einer Offset-Druckmaschine zur Aufnahme eines flachen Gummituches aus elastisch verformbarem Material, dadurch gekennzeichnet, dass in der Druckbreite ein im wesentlichen parallel zur Drehachse des Gummituchzylinders (3, 6) verlaufender abgesetzter Oberflächenbereich (4, 7) in Form einer im wesentlichen konstanter Durchmesserverringerung vorgesehen ist, in den eine zumindest an der Aussenseite konkav gefertigte Folie (5, 8) eingebracht ist, die den Oberflächenbereich (4, 7) ausfüllt.
- Gummituchzylinder nach Anspruch 1, dadurch gekennzeichnet, dass der abgesetzte Oberflächenbereich (7) symmetrisch zur Mitte des Gummituchzylinders (6) etwas konkav angeschliffen ist, in den eine Folie (8) eingelegt ist, die den Oberflächenbereich (7) ausfüllt.
