    摘要： By optimizing the pressure condition for sucking up an excess of coating liquid with a recovering slit, a coating layer on a web with a very small and even thickness can be obtained. In a coating method using two slits of a coating slit and the recovering slit, a liquid pressure P (MPa) at a suction port of the recovering slit is adjusted in a range of 0.05>P≧0. Thus, coating thickness variations in the web width direction of the coating layer formed on the web can be restrained, and score-like coating omission can be prevented from occurring on the coating layer surface.

    摘要： Edge faces with level differences are formed by assembling blocks constructing a coating head, and level difference variances in the width direction of a web are measured by a level difference variance measurement device. Then, the level difference variances are adjusted with reference to measured results, so that the level difference variances can be reduced. Therefore, coating layers can be uniformly formed on the web.

    摘要： A method for manufacturing a magnetic recording medium includes steps of forming a magnetic layer containing magnetic powder particles on a web-like non-magnetic support being continuously transported in one direction and applying a magnetic field to the magnetic layer by a plurality of magnets in such a manner that an angle of the magnetic field applied to the magnetic layer to the transporting direction of the non-magnetic support in a plane perpendicular to a surface of the magnetic layer and parallel to the transporting direction of the non-magnetic support gradually increases in the transporting direction of the non-magnetic support, thereby orienting the magnetic powder particles in an oblique direction with respect to the surface of the magnetic layer. According to this method, it is possible to orient magnetic powder particles in a desired direction with respect to the surface of a magnetic layer and to manufacture a magnetic recording medium having a high squareness ratio without increasing the size of the apparatus.

    摘要： In the condition that a support is liquid-sealed with a precoat solution mainly containing a solvent and being applied onto the coating surface of the support in advance, a coating composition, prepared by dispersing powder of a mean particle size not larger than 0.4 .mu.m, is applied so as to be laminated onto the precoat solution by means of an extrusion head. The extrusion head has a front edge located at the upstream side with respect to the direction of movement of the support, and a back edge located at the downstream side with respect to the direction of movement of the support so that an end of the back edge retreats farther from the support with a difference in level than the front edge. The wet film thickness of the precoat solution is made to be in a range not larger than 1/3 of the wet film thickness of the coating composition. A coating method in which the surface quality of a coating film formed on a surface of a support can be improved is therefore provided.

    摘要： A coating method for applying a coating composition mainly containing an organic solvent onto a running flexible support 11 by ejecting the coating composition in an oversupply state from a slit 9 under pressure. A back edge top end surface 14 on the upstream side in the direction of running of the support with respect to the slit is set so as to be substantially parallel to the surface of the support. A liquid-detached position in which the coating composition ejected from the slit to overflow the slit is detached from a surface of the support 11 is set so as to be placed on the back edge surface opposite to the support.

    摘要： A coating method and apparatus employing an extrusion-type coating head in which the probability of damaging the surface of the layer being formed on a support is remarkably decreased. Coating solution, such as a magnetic solution for forming a magnetic recording tape or the like, is supplied by a pump through a pipe line and thence a filtering element to the extrusion-type coating head, which applies the coating solution onto a support being run directly or through a coating roll. The filtering element, which is disposed at or near the coating solution supplying inlet of the extrusion-type coating head, has openings whose diameter is smaller than a coating clearance between a doctor edge of the extrusion-type coating head and the support or coating roll.
