Abstract

Ce dispositif comporte un support d'images et un système d'application du produit de virage du type << à brosse >>, constitué par un rouleau-brosse et un aimant placé à l'intérieur de celui-ci. Il est caractérisé en ce que l'aimant et le rouleau-brosse sont montés fixés et en ce que l'aimant est un électro-aimant multipolaire avec un bobinage triphasé.This device comprises an image support and a system for applying the toning product of the "brush" type, consisting of a brush roller and a magnet placed inside the latter. It is characterized in that the magnet and the brush roll are mounted fixed and in that the magnet is a multipolar electromagnet with a three-phase winding.
