Definitions
- the invention relates to a method for producing round, metallic Sleeves as coating carriers, on which function-specific, below multilayer layers can be applied, for example compressible Layers for offset printing.
- DE 41 40 768 C2 discloses a method for producing an offset printing form a metallic material for a forme cylinder of a printing press.
- the plate-shaped blank is opened for printing plate production conventional type coated and exposed, after which the rectangular plate in a welding device by bending into a Bring hollow cylinder shape and clamped there in register.
- the one on top of the other facing edges of the plate are longitudinally welded together, whereby the welding process is carried out in such a way that a weld seam is formed which is on the top and Underside has a concave shape.
- the resulting printing form on the Forme cylinders are coated and exposed.
- a disadvantage of this manufacturing process is the fact that the length is stretched of the plate-shaped blank, which will later give the diameter, exactly parallel and with a correspondingly high accuracy of significantly better than 1/10 mm tailored. It also causes the introduction of heat when welding causes longitudinal distortion of the material in the weld area. This elongation leads to a ripple on both sides along the weld. When using a sleeve produced in this way leads to the inevitable waviness in the seam area to the fact that air pockets occur, which are under external pressure on the sleeve this migrate, which causes the sleeve to twist on the cylinder.
- DE 39 08 999 C2 discloses a cylinder body and a method for coating of the cylindrical body. It is proposed to have a cylindrical body like this to be provided with a seamless coating that as a coating material thixotropic multi-component material in the form of a propellant and inhibitor staggered, flowing foam with rotation and feed on the cylindrical body is applied approximately in a spiral.
