Abstract:
1. An electro-dip lacquering device with a) a lacquer bath; b) a conveying device, with which the workpieces to be lacquered can be dipped in a continuous operation into the lacquer bath, moved through this and lifted out again; c) a voltage source; d) electrodes arranged in the lacquer bath along the movement path of the workpieces, which electrodes are connected to a first pole of the voltage source; e) a contact rail, which extends along the movement path of the workpieces and is connected to the second pole of the voltage source; f) a contact device, which is in contact with the contact rail, for each workpiece; g) at least one control system, with which the voltage present at each workpiece can be set during its movement through the lacquer bath; wherein h) the contact rail is uninterrupted over its entire extension through the lacquer bath; i) arranged between each contact device and the related workpiece is a controllable voltage adjusting unit; j) a position indicating device is provided, which determines the momentary position of each workpiece and emits a corresponding signal to the at least control system; k) the at least control system is designed so that from the signal supplied to it by the position indicating device it determines for each workpiece a voltage at which the workpiece is to be at this position, and emits a corresponding control signal to the voltage adjusting unit of the corresponding workpiece.
