The present invention is intended to solve a problem that a coating film has an uneven thickness in the case where a coating target 1 has a stepped portion extending in a predetermined direction on its coating surface. To solve the problem, a follow-up coating is performed along the stepped portion S extending in the predetermined direction after coating of the entire coating surface of the coating target 1 so that paint mist adheres more to a relatively-recessed side of the stepped portion S.

The invention related to a device (1) for spraying charged droplets of a liquid towards a target along a spraying direction, comprising: a reservoir (10) for storing the liquid (L), a first electrode (100) being arranged at an outlet (11) of said reservoir (10), a second electrode (200) forming a counter electrode to the first electrode (100) for accelerating said droplets (D) along the spraying direction (S), and a housing (30) holding the reservoir (10) as well as said electrodes (100, 200).

A working chamber system for the surface treatment of workpieces comprises at least one tightly closable work chamber (101), a frame-like workpiece holder (10, 20, 30) which is displaceable on a guide rail between a mounting position outside the work chamber (101) and a working position in the work chamber (101), and a manipulator which, as seen in plan view, is arranged next to a group of parallel guide rails within the work chamber (101). At least one of the workpiece holders (10, 20, 30) has an external frame (11, 21, 31), via which it is guided in the guide rails, and an internal frame (12, 22, 32) which is surrounded by the external frame (11, 21, 31) in a transporting position and which is displaceable into a position outside the main plane of the external frame (11, 21, 31) in the mounting position and/or the working position.

An electrodischarge apparatus has a nozzle that includes a discharge chamber that has an inlet for receiving a liquid and an outlet. The apparatus has a first electrode extending into the discharge chamber that is electrically connected to one or more high-voltage capacitors. A second electrode is proximate to the first electrode to define a gap between the first and second electrodes. A switch causes the one or more capacitors to discharge across the gap between the electrodes to create a plasma bubble which expands to form a shockwave that escapes from the nozzle ahead of the plasma bubble.
