Coat-stripping unit and method for its operation

A coupling ( 7 ) which is rotatable about a vertical axis of rotation and intended for the mounting of a workpiece support ( 15 ) which can be loaded, for example, with incorrectly coated or worn workpieces ( 18 ) is arranged in a removable holder ( 5 ) above a tank ( 2 ) filled with an electrolyte....

Zusammenfassung:	A coupling ( 7 ) which is rotatable about a vertical axis of rotation and intended for the mounting of a workpiece support ( 15 ) which can be loaded, for example, with incorrectly coated or worn workpieces ( 18 ) is arranged in a removable holder ( 5 ) above a tank ( 2 ) filled with an electrolyte. Said workpiece support is connected via the coupling ( 7 ) to a current supply device, to the opposite pole of which an opposite electrode ( 12 ) is connected. A heating and cooling device ( 13 ) and an ultrasound generator ( 14 ) are also arranged in the tank ( 2 ). By current supply and simultaneous rotation, the coat is stripped from the workpiece support ( 15 ) and/or from the workpieces ( 18 ). After incorrect coating, the workpieces ( 18 ) together with the workpiece support ( 15 ) and in certain circumstances with the holder ( 5 ) can be taken over directly from a coating unit and, after coat stripping, transferred to such a coating unit for recoating.
