Abstract: In an extrusion coater having at least two coating slots (8, 8'), the central line between the coating slots is arranged perpendicular to the plane of the substrate (1) and the terminating edge (15) of the separator (16) between the two coating slots is a downward-sloping surface. Opposite the extruder orifice and behind the substrate is the edge (5) of a magnet (2) which draws the magnetizable layers out of the coater outlet orifice (3), the edge (5) being arranged at the height of the common outlet orifice of the coating slots (8, 8'). By means of this arrangement, a uniform coating is achieved even in the case of very thin double layers and even at high coating speeds.
