Abstract

In the case of an apparatus for electro-dipcoating small electrically conductive parts, having a tank (6) with a predetermined filling height for receiving a dipping bath of electrically conductive, liquid coating agent, a delivery tube (1), which is rotatable about its axis, for transporting the small parts in its longitudinal direction, having a small-part inlet opening (4), a small-part outlet opening (12) and a ribbon screw (5) attached to the inner side of the delivery tube (1), the delivery tube (1) being arranged in relation to the tank (6) in such a way that a coating section (9) of the delivery tube (1) extending in the longitudinal direction of the said delivery tube (1) lies partly below the predetermined filling height of the tank (6), and a first electrode (16), which is connected to one pole of a current source and is arranged on the inner side of the coating section (9) of the delivery tube (1), and a second electrode (14), which is connected to the other pole of the current source. The object is to improve the quality of the coated small parts. This object is achieved by the second electrode (14) being arranged within the coating section (9) of the delivery tube (1), in the tank, below the predetermined filling height of the tank.
