Coating device by extrusion applicator of magnetizable binder-containing layer to nonmagnetic substrate

摘要

The present invention relates to an apparatus for applying a magnetic dispersion to a nonmagnetic substrate, which is disposed opposite a discharge slot of an extrusion applicator and optimized by a magnet coated by bending with a soft iron strip. The inlet edge of the ductile iron strip is arranged substantially opposite the outlet slot. Sliding behavior of the substrate is improved during application by the curved guide member on the front side of the ductile iron strip.
