Abstract

A knife coater for the application of one or more magnetizable dispersions located one on top of the other to a moving flexible substrate by means of a plurality of coater slots which are arranged essentially horizontally and parallel to one another in a multipart block and are fed from reservoirs is described, the outlet orifices of the coater slots being essentially opposite the summit of a concave support surface for the substrate, the substrate transporting the applied layers, the outlet surfaces of the coater block which are opposite the support surface being adapted to the radius of the roll and the inflow gap being larger than the outflow gap.
