An electro-dipcoating apparatus is described in which, in conventional manner, a work-piece to be lacquered is dipped into a lacquer bath, moved through the latter, and lifted out again in a continuous process. Along the path of motion of the work-piece in the lacquer bath there are arranged electrodes which are connected to a first pole of at least one voltage source. Several contact rails extend parallel to one another without electrical interruption along the entire path of motion of the work-piece leading through the lacquer bath and are each connected to the second pole of varying voltage sources. To each work-piece a contact device is assigned which can be brought into communication with a respective one of the several contact rails and in this way applies the potential of the second pole of the corresponding voltage source to the work-piece. In this way, cuts in the contact rails are avoided that would result in wear of the contact devices and in increased control effort.
