Abstract:
1. An electro-dipcoating apparatus for coating a work-piece, the electro-dipcoating apparatus comprising: a lacquer bath; a conveying device by which the work-piece to be lacquered can be dipped into the lacquer bath, moved through the latter, and lifted out again in a continuous process; at least two voltage sources; electrodes arranged in the lacquer bath along the path of motion of the work-piece, which are connected to a first pole of the at least two voltage sources; several contact rails which extend parallel to one another without electrical interruption along an entire path of motion of the work-piece leading through the lacquer bath each of the contact rails being connected to a second pole of one the at least two voltage sources; and, a contact device which is connected to one of the several contact rails and which applies a potential of the second pole of one of the at least two voltage sources to the work-piece.
