    摘要： A coating method and an extrusion-type coating head in which turbulence at the junction between two flows of coating materials is prevented to provide multi-layer simultaneous coating over a wide range of coating rates and with a good coating quality. An intermediate block is sandwiched between a rear block defining a back edge and a front block defining a doctor edge. Two coating flows pass through slits formed on either side of the intermediate block, joining at the top end of the intermediate block and flowing together into a short slot extending between the end of the intermediate block and the outlet of the head.

    摘要： A method of applying a liquid to a moving web while pushing an extrusion application head to the moving web without supporting the moving web on the reverse side thereof. The application is performed while the accumulation of the liquid to be applied to the moving web is maintained by (a) the moving web and (b) an edge of the back blade of the extrusion application head, the edge being defined by the intersection of (1) a first surface of the back blade which faces the front blade and which is nearest the web, and (2) a second surface of the back blade which is more remote from the front blade than the first surface and, wherein the pressure of the liquid of the accumulation located between the web and the outlet portion of the slit of the extrusion application head is set within a range from 0.2 kg/cm.sup.2 gauge to 0.8 kg/cm.sup.2 gauge per 50 cm of width of applied liquid.

    摘要： A method for coating a running support with a coating solution, such as in the production of a magnetic recording medium, in which spreading of the coating solution into edge portions of the support not intended to be coated with the coating solution is prevented, hence providing a coating layer uniform in thickness and with good surface characteristics. Immediately before application of the coating solution to the support, a solvent is applied to regions of the support which are not to be coated with the coating solution and which are located on both sides of the coating region to be coated with the coating solution. In accordance with the invention, the solubility parameter of the solvent is made different from that of a solvent contained in the coating solution by at least 1.2 at a temperature of 25.degree. C.

    摘要： An application device for applying a coating liquid to a moving web which forms an applied layer of uniform thickness and with smooth surface properties. The sides of a slotted portion of an extrusion-type application head are provided with sloped or stepped portions in regions adjacent liquid-free areas of the web. This prevents scratching of the web and accumulation of extraneous matter at the edge portions of the application head.
