Abstract

An electrically conducting oblong substrata (1) in the form of a continuous band moves vertically through a depositing enclosure (2). The powder is introduced into the enclosure continuously and an electric field is created in the enclosure, by means of electrodes (9), enabling the powder (5) to be applied on one of the faces of the substrata. The powder is supplied in the upper part of the enclosure so as to move by gravity along the substrata surface.
