Abstract: Disclosed are a method and a device for plasma treating workpieces (5). Said workpiece is inserted into a chamber (4) of a treatment station (17), which can be at least partly evacuated, and at least one part (18) of the treatment station is moved relative to another part (27, 35) thereof in order to help manipulate the workpieces. The movement is carried out in such a way that a shell-shaped chamber wall (18) is positioned relative to a floor (35) of the chamber and relative to a chamber lid (27).

Abstract: The invention relates to a method and an apparatus for the treatment of substrates, in particular for the coating of plastic containers on a rotary installation. A plurality of treatment devices are arranged on the rotor and pass through a plurality of process phases as a function of their angle position on the rotor. For at least one process phase, the angle position can be set variably as a function of the current rotational speed of the rotor.

Abstract: A device for holding and vacuum-sealing a container as used in particular in the internal and/or external coating of containers. The device holds and vacuum-seals at least one container and has a sealing device for sealing the pouring opening in a defined end state also to comprise a holder with an introduction region, into which the wall region, which adjoins the pouring opening, together with the pouring opening, can be at least partially introduced, and a cage, which interacts with the holder and holds at least one clamping element in such a manner that, when force is applied to the cage in the direction in which the container is introduced into the defined end state, the clamping element can be guided out of a position in which it substantially releases the introduction region into a position in which it projects into the introduction region.

Abstract: Disclosed are a method and a device for plasma treating workpieces (5).
