PCT No. PCT/EP97/00747 Sec. 371 Date Feb. 12, 1998 Sec. 102(e) Date Feb. 12, 1998 PCT Filed Feb. 17, 1997 PCT Pub. No. WO97/30443 PCT Pub. Date Aug. 21, 1997An apparatus for applying magnetic dispersions to nonmagnetic substrates is optimized by means of an attracting magnet which is opposite the application slot of an extrusion coater and is covered with a soft iron strip in an angular manner. The leading edge of the soft iron strip is arranged virtually opposite the application slot. A curved guide element in front of the soft iron strip improves the gliding behavior of the substrate during application.
