Abstract: An apparatus for coating surfaces of objects by a gas deposition method under vacuum conditions in process chambers, including at least one treatment chamber for receiving the objects to be coated and at least one additional process chamber, connected to the at least one treatment chamber, for conducting gases to be deposited and/or discharging portions of non-deposited partial gas quantities. A measuring unit for detecting the coating thickness on a surface or sections of the surface of the process chambers is arranged in at least one additional process chamber. The measuring unit is connectable to a control and evaluation unit. The measuring unit detects ACTUAL data of the coating thickness on a surface of the at least one additional process chamber as measured value and these ACTUAL data are forwarded to an evaluation device, in which these ACTUAL data are compared with NOMINAL data.

Abstract: A support frame for a pump stand for receiving vacuum pumps for a coating device for coating containers by a coating method. The support frame includes a structure on which bearing struts are formed for detachably connecting to at least two bearing devices, onto which a respective vacuum pump can be detachably mounted. Feet extend downwards from the lowermost bearing struts and have detachable securing devices for connecting to a main support frame of the coating device. The hearing devices have a rectangular cross-section, which is slightly larger than the cross-section of a fork of a lifting truck or a forklift truck, and which are sufficiently spaced apart from one another in the horizontal direction so that the fork of the lifting truck or the stacking fork of the forklift truck can be moved therein with minimal play.

Abstract: A device for the plasma treatment of containers comprises a process gas producer for producing a process gas mixture and at least one coating station, which comprises at least one plasma chamber having a treatment place, in which plasma chamber at least one container having a container interior can be inserted and positioned on the treatment place, each plasma chamber being at least partially evacuable in order to suck the process gas provided by the process gas producer through the container, the interior thereof thus being provided with an inner coating by means of plasma treatment, and pressure-measuring apparatuses being provided at predefined points of the device in order to ensure the process stability. The pressure-measuring apparatuses at least at some of the predefined points of the device comprise gas-type-dependent pressure transducers.

Abstract: A method and a device for plasma treatment of containers by means of a plurality of treatment segments each having at least one plasma station on a plasma module comprising a plasma wheel, wherein, during an operational malfunction and/or a cut-out in at least one of the plasma stations, the process gas, before being supplied to the plasma station in question, is carried off into the respective plasma chamber and/or the container held therein, by means of at least one bypass line.

Abstract: Device for coating containers by a coating method. The device includes a carrier frame having outer dimensions less than the inner dimensions of an ISO container. The carrier frame includes within its outer dimensions: a conveying region where a conveying device for the containers is arranged; a treatment region where a container treatment unit for coating the containers is arranged; a transfer region where a transfer device is arranged; which moves the containers between the conveying device and the container treatment unit; a maintenance region accessible from outside, in which no components are arranged; an electronics region, where a switchgear cabinet for the electronics of the components of the device is arranged; a process-gas processing region, where the components for handling the process gas for the coating method are arranged; and a vacuum pump region, where vacuum pumps for producing the vacuum needed for a coating method are arranged.

Abstract: A device for coating containers using a coating process with a main supporting frame, which includes: a container conveying device, a treatment station for coating the containers, and a transfer device, which moves the containers between the conveying device and the treatment station. The transfer device has a gripper unit, which is mounted pivotably along a pivot axis aligned parallel to the conveying device on a gripper frame, which is arranged fixed in place in relation to the main supporting frame during operation. The gripper unit is mounted on a carriage connected to the gripper frame. Thee carriage performs linear movements in three mutually perpendicular directions. The gripper unit is movable between a first position, in which it can grip the containers in the region of the conveying device, and a second position, in which it can insert the containers into the treatment station and fetch them from it.

Abstract: The method serves for the plasma treatment of container-like workpieces. The workpiece is inserted into an at least partially evacuable chamber of a treatment station. The plasma chamber is bounded by a chamber base, a chamber cover and a lateral chamber wall. The plasma treatment causes a coating to be deposited on the workpiece. The plasma is ignited by microwave energy. The coating consists at least of a gas barrier layer and a bonding layer arranged between the workpiece and the gas barrier layer. The gas barrier layer contains SiOx and the bonding layer contains carbon. The gas barrier layer is produced from a gas that contains at least one silicon compound and argon.

Abstract: The method serves for the plasma treatment of workpieces. The workpiece is inserted into a chamber of a treatment station that can be at least partially evacuated. The plasma chamber is bounded by a chamber bottom, a chamber top and a lateral chamber wall. The plasma treatment involves depositing a coating on the workpiece. The ignition of the plasma is performed by microwave energy. The coating consists at least of a gas barrier layer and a protective layer. The gas barrier layer contains SiOx and the protective layer contains carbon. The protective is produced from a gas that contains at least a silicon compound and argon.
