Abstract

Device for the vacuum coating of mass produced products. By means of the ice small parts, such as screws and bolts, as mass produced products are highly productively coated by vacuum deposition or sputtering, also under plasma action. In a container is located a drum rotatable at high speed about its horizontal axis and in which the parts to be coated are fixed to the inner wall by centrifugal force. The surface of the inner wall is geometrically constructed such that the parts to be coated are reliably held and moved with it. The coating devices are located in the drum. A stripping device, whose spacing with respect to the inner wall is adjustable at programmable time intervals, is located in the drum and has an abutment surface directed opposite to the rotation direction.
