Abstract: The invention relates to a method for the automated decoration of a building board, comprising at least one smoothing compound layer and preferably at least one colour coat. The method comprises the steps of smoothing and decorating the building board, wherein the smoothing includes the steps of (i) calibrating the building board to a nominal thickness, so that a surface of the building board has a height difference of at most 1 mm, (ii) applying a layer of a smoothing compound, (iii) pressing the smoothing compound into the surface structures of the building board, and (iv) recalibrating to the nominal thickness. Preferably, a plurality of smoothing compound layers are pressed into a calibrated surface of the building board and partially ground away again. The method is particularly well suited for the production of fire-resisting building boards.

Abstract: A tubular target is formed of refractory metal or a refractory metal alloy. The target has at least one tubular portion X with a relative density RDx and at least one tubular portion Y with a relative density RDy. At least one tubular portion X has, at least in some regions, a larger outer diameter than a tubular portion Y at least in some regions. A density ratio satisfies the relation (RDy?RDx)/RDy?0.001. There is also described a method for producing a tubular target from refractory metal or refractory metal alloy by sintering and local deformation of different degree. The tubular target has a more uniform sputter removal over the entire surface area compared with prior tubular targets. The tubular targets do not exhibit any tendency to arcing or to particle regeneration.
