    摘要： An application device for applying a liquid such as a magnetic coating liquid to the surface of a continuously moving web in which the amount of chipping of the surface portions of the outlet portion of the coating head thereof, and hence the amount of streaking in the applied layer of liquid, are remarkably reduced. The outlet portion of the application head is made of a very hard alloy, preferably tungsten carbide, containing crystal grains of a carbide 5 .mu.m or less in mean diameter conjoined to each other by a metal, preferably cobalt in an amount of 12% or less.

    摘要： A method for manufacturing a magnetic recording medium in which shavings are not generated when an easily bent thin web comes into contact with contact members of a coating head, a conveying system, rolls in calendaring treatment, etc., in which, during coating, a coating having an even coating thickness and good surface properties is formed, and in which a coating liquid does not spread in such a manner as to cause defects such as coating unevenness and the like. In accordance with the inventive method, to manufacture a magnetic recording medium in which a coating liquid is applied onto a surface of a continuously running flexible support except widthwise edge portions of the support while a slot top end of a coating head is pressed against the surface of the flexible support, a material selected from a polymer film, a carbon dispersing liquid, a fatty-acid lubricant, and a fluorine-group lubricant is applied onto at least portions of the flexible support corresponding to the edge portions. The material applied to the edge portions of the flexible support is dried to thereby form a coating at the edge portions of the flexible support. The coating liquid is then applied onto the surface of the flexible support.
