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 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 multi-layer coating method by which multi-layered magnetic recording media having good recording characteristics can be produced consistently at high speed with multiple thin layers being coated simultaneously while insuring effective prevention of unwanted phenomena such as color unevenness and longitudinal streaks. A plurality of organic solvent based dispersions that are non-Newtonian fluids having fine particles dispersed therein are simultaneously applied in superposition onto a continuously running nonmagnetic support using an extrusion type applicator head. The coating operation is performed in such a manner that the Reynolds number as determined by the average of the kinetic viscosity coefficients of the dispersions, the coating speed and the equivalent diameter during coating is adjusted to 400 or below, and that, at the same time, the yield stress of at least the dispersion for the topmost layer is adjusted to 10 dyne/cm.sup.2 or more. Further, the coating operation is performed in such a way that the ratio of .eta..sub.T to .eta..sub.H is adjusted to 50 or above, where .eta..sub.H is the viscosity of the dispersions at the rate of shear that is exerted upon the dispersions when they are applied using an extrusion type applicator head, and .eta..sub.T is the viscosity of the dispersions at the shear rate for the time period defined by the end of application and the entrance into the subsequent drying zone.

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 vibration damper for use with an apparatus for applying liquid to both sides of a running web and then drying the web with an air drier. Vibrations induced by the air drier are damped by uniformly blowing air on both sides of the running web between the drier and the liquid application heads. Preferably, the gas ejection surfaces are stepped or tapered so allow larger vibrations near the drier but to reduce the allowed vibration nearer the liquid application heads.

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.
