Abstract: An apparatus for coating a PET container in a coating chamber includes a lance that introduces material and energy into the container while it is in the coating chamber. This results in a reaction that coats the bottle's interior with a silicon oxide. Before reaching the coating chamber, the bottle will have passed through a cooling system connected to coating chamber. The cooling system passes cooled gas through a feed, thereby cooling said bottle before it reaches the coating chamber.

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: The present invention relates to a device for coating containers with a barrier layer having at least one plasma chamber, which encloses at least one treatment space, in which at least one container with a container interior can be inserted and can be positioned on the treatment space, wherein a gas lance is provided which can be introduced into the container interior and which further acts as microwave antenna, with the plasma chamber being designed to be capable at least of partial evacuation and being designed to fill the container interior at least partially with a plasma and a process gas. The device is designed such that the container can be preheated by means of a plasma, more particularly by means of a microwave plasma, using a noble gas which can be introduced into the container interior through the gas lance.

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: A method for the plasma treatment of a workpiece that includes inserting the workpiece into a plasma chamber and depositing, with the effect of a partial vacuum after plasma ignition, a coating on the workpiece by plasma treatment. Plasma ignition occurs by pulsed microwave energy, and alternating “on” phase times and “off” phase times from pulsed microwave excitation are provided by a control. During a beginning portion of the plasma treatment, a first portion of the coating is deposited. Subsequently, a quotient of the “on” phase times and the “off” phase times is increased to deposit a second portion of the coating, which has a different composition than the first portion of the coating. The quotient of the “on” phase times and the “off” phase times is then decreased to form a third portion of the coating, which has a different composition than the second portion of the coating.
