摘要： A coating method and a coating apparatus are constructed for simultaneously coating a plurality of different organic-solvent-based coating liquids each composed of a non-newtonian fluid having fine particles dispersed therein to form a multi-layered structure having three or more layers on a strip of continuously travelling non-magnetic supporting substrate with the aid of an extrusion type coating head. The coating liquids are instantaneously injected through the corresponding slits. The coating liquid for the lowermost layer is a non-magnetic liquid. The coated layers are successively formed one above another with the aid of a doctor edge plane located on the downstream side of each slit. The coating head is constructed such that each doctor edge plane does not pass a tangential line extending from the upstream end of an opening portion of each slit to a doctor edge of a slit located on the downstream side and that a coating liquid injected through a slit on the upstream side merges with a coating liquid injected through a slit on the downstream side while defining a predetermined merging angle therebetween.

摘要： A method for producing a magnetic recording medium in which widthwise deviations in thickness of coating caused by widthwise unevenness of the support being coated are suppressed so that the coating thickness is made uniform. An extrusion-type coating head is used for coating, and a magnetic coating composition is continuously extruded from a top end portion of a slit of the coating head onto the surface of the support while the support is running continuously along a back edge surface and a curved doctor edge surface having a curvature thereby to coat the surface of the support with the magnetic coating composition, the method being characterized in that coating is carried out in such manner so that the following condition is satisfied:

12µ( m / d ³) Ut > 0.20( T / R )

where -
µ: composition viscosity (poise)
m : slit length (mm)
d : clearance of the slit (mm)
U : coating speed (m/sec)
t : coating thickness (µm)
T : tension at a coating portion (kgf/whole width)
R : radius of curvature of the doctor edge (mm).

摘要： A coating method and a coating apparatus which assure that an upper layer and a lower layer, each composed of a thin film, are excellently simultaneously coated on a web while forming a laminated structure without the appearance of strip-shaped irregularities in the coated layers, not only by preventing foreign particles in the coating liquids from being entrapped on a doctor edge surface, but also by preventing the boundary surface between the upper layer and the lower layer from being adversely disturbed. Each of a first doctor edge and a second doctor edge has an arc-shaped sectional contour. An imaginary straight line L₁ tangentially extends along the doctor edge surfaces of the first and second doctor edges. With a position where the straight line L₁ intersects a perpendicular line extending upward of an upstream end of the second doctor edge designated by an intersection D, a distance t between the upstream end B and the intersection D is within the range of 5 µm ≦ t ≦ 50 µm.

摘要： A liquid application method by which a high-quality magnetic recording medium of good electromagnetic converting property can be stably manufactured with high yield and high productivity over a wide ranges of manufacturing factors while preventing chromatic nonuniformity and longitudinal streaking, even if the application head is replaced. A quantity of the liquid larger than the applied quantity of the liquid to the carrier is supplied by liquid feed means into the liquid reservoir of the extrusion head which communicates with the slot, a portion of the liquid in the reservoir is forcibly drained therefrom by liquid drain means though a liquid drain port provided at or near a position farthest from the position of a liquid feed port for the reservoir along the width of the carrier, a bypass connected to changeover valves immediately upstream and downstream of the head and a return passage branched from the bypass are provided, and flow rate control valves are provided in the bypass and the return passage.

摘要： A coating apparatus for forming one or more coating layers on a substrate by means of an extrusion-type head comprising a front edge located on an upstream side with respect to a moving direction of the substrate and a back edge which is located on a downstream side in the moving direction of the substrate. The back edge has a corner portion partially defining an extrusion slot and which is displaced further from the substrate than the front edge in a state in which a precoating solution comprised mainly of an organic solvent is applied in advance on a coating surface of the substrate. A chamfered surface is formed on the corner portion. According to the invention, an angle alpha formed by the chamfered surface and a downstream inclined surface of the back edge is such that 40 DEG ≤ alpha ≤ 140 DEG , an angle beta formed by chamfered surface and an upstream inclined surface of the back edge is such that 40 DEG ≤ beta
