Patent ID: 6841048

Claim:
A coating apparatus for disk-shaped workpieces, comprising: a transport chamber ( 3 ); and a workpiece transport configuration ( 11 ) which comprises; at least two linearly extendable and retractable transport rams ( 15 ) driven under control and connected with a rotational axis (A) driven under control, which are within shell lines of a rotation body about the rotational axis (A) and which can be extended and retracted in the same direction with respect to a direction on the rotational axis; and a workpiece receiver ( 17 ) at the ends on each ram ( 15 ); at least two operating openings ( 19 B , 19 S ) by which the transport chamber ( 3 ) communicates with stations ( 21 , 23 ), of which one is a coating station, wherein the surface normals (N) of the operating openings are directed in the direction of shell lines of the rotation body; a pump unit ( 34 ), communicating via a pump opening ( 30 ) with the transport chamber ( 3 ), for the transport chamber ( 3 ) as well as also for the coating station ( 21 ); and wherein at least one of the rams ( 15 ) comprises at its end a closure configuration ( 17 ) or can be equipped therewith, is orientable toward the pump opening and the closure configuration, and, with orientation of the ram ( 15 ) onto the pump opening ( 30 ) and subsequently its extension (F), enters into an operational connection forming a sealed closure.
