Abstract
Method and apparatus for sputter coating of printing or similar type cylinders by means of r.f. sputtering in which each of the cylinders being coated comprises a thin, metal sleeve of cylindrical configuration mounted on a mandrel. A plurality of mandrels is mounted in a sputtering chamber on a spider which is rotated coaxially with a cylindrical target, the target being stationary. A fixed ring gear cooperates with pinions on each of the mandrels to impart an epicyclic movement to the mandrels, each of which mounts a sleeve. An r.f. sputtering condition is created in the chamber between the target and the cylinders so that a plurality of cylinders is coated simultaneously. The chamber can be opened to remove the cylinders after sputtering to replace them with others to be coated, this without disturbing the target.
