Provided is an apparatus and a method for coating objects and in particular containers with at least one first and one second coating station, wherein these coating stations each have at least one first coating electrode and one second coating electrode, and with a supply device for electrical supply of in each case at least one of the coating electrodes. The supply device has a high-frequency generator device for generating an a.c. voltage and/or voltage pulses as well as an a.c. voltage distribution device which distributes this a.c. voltage and/or the voltage pulses respectively to in each case at least one electrode of the first coating station and at least one electrode of the second coating station, wherein the a.c. voltage distribution device is suitable and intended for distributing the a.c. voltages and/or the voltage pulses with a time delay to the electrodes.
An apparatus for coating objects wherein the objects are containers with at least one first and one second coating station, wherein these coating stations each have at least one first coating electrode and one second coating electrode, and with a supply device for electrical supply of at least one of the coating electrodes, wherein the supply device has a high-frequency generator device for generating at least one of an a.c. voltage and voltage pulses as well as at least one of an a.c. voltage distribution device designed as a multiplexer which distributes this a.c. voltage and the voltage pulses respectively to at least one coating electrode of the first coating station and of the second coating station, wherein the a.c. voltage distribution device is suitable and intended for distributing at least one of the a.c. voltages and the voltage pulses with a time delay to the coating electrodes, wherein the a.c. voltage distribution device distributes the pulses output by the high-frequency generator device completely to the individual electrodes in such a way that each pulse is assigned to precisely one coating station and there is no overlap between the pulses going to the individual coating stations.
A method for coating objects wherein the objects are containers with at least one first and one second coating station, wherein these coating stations each have at least one first coating electrode and one second coating electrode, and wherein with a supply device at least one of the coating electrodes is supplied with electrical energy, comprising the steps of:
