摘要： An extruder for coating magnetic layers onto electro-magnetic recording tape is disclosed, which is provided with two reservoirs and two outlet channels so as to permit simultaneous coating of two layers. The two outlet channels meet at an angle and merge into a single outlet channel, which extrudes the two layers between a front edge and a rear edge. The front edge has a shape of curvature, and the rear edge protrudes beyond a tangential line drawn from the end of the front edge curvature. The extruder is capable of producing double layered magnetic tape with or without a mixed zone between layers.

摘要： The invention provides an apparatus for coating a solution on a tape-shaped flexible support which is moved so as to run along a top surface of coating head. The coating head is slitted so as to form a front edge surface, a back edge surface in order in the moving direction of the flexible support, and a slit therebetween so that the solution is extruded through the slit of the coating head to the flexible support. In this configuration, at least a part of the back edge surface projects beyond the tangent line at the downstream end of the front edge surface.
