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

摘要： A coating apparatus in which variations in the thickness of coating films in the width direction or the production of stripes caused by the nonuniformity of a support in the width direction are prevented so that products coated with thin films uniform in coating thickness can be manufactured stably at a high speed. In the coating apparatus, a precoat composition is applied in advance onto a coating surface of a support, and in a liquid-sealed condition in which entrained air is eliminated between the precoat composition and a front edge (21) on the upstream side in the moving direction of the support, at least two layers of coating compositions are discharged from between the front edge (21) and a back edge (24) having a top end (60) set back from the front edge (21) in the direction against the support. The coating apparatus is configured so that a relationship a > b is established between a slot outlet width a , the distance between an edge surface rear end (31) of the front edge (21) and a top end (60) of the back edge (24), and a distance b in the direction of a slot depth from a straight line X expressing the first-mentioned distance to a top end of the deepest intermediate block (22) disposed between the two edges.

摘要： The present invention forms non-magnetic particles in a acicular shape as dispersed in a dispersoid liquid, forms a lower non-magnetic layer by coating the above-mentioned dispersoid liquid on a continually transported non-magnetic supporting base, forms an upper magnetic layer by coating the above-mentioned magnetic coating liquid in dual layers either consecutively or at the same time while the lower layer is still in its wet state, and performs an orientation of the magnetic particles by exposing the particles to a magnetic field while the dual layers as thus formed are still in their undried state. The orientation effect is achieved by making the specific gravity of the non-magnetic particles equal to or greater than that of the magnetic particles. The orientation effect is further enhanced by making the particle size of the non-magnetic particles equal to or less than that of the magnetic particles as measured along the long axis of the magnetic particles.

摘要： A coating method and coating apparatus with which a thin film having a uniform thickness free from stripe or step unevenness of a coating composition is formed at a high speed. An extrusion-type coating head is provided which has a front edge and at least one back edge, the front edge being disposed on the upstream side in the direction of movement of a support, the back edge being disposed on the downstream side in the direction of movement of the support, and the back edge having a top end which is set back stepwise from the front edge in the direction away from the support. Coating is performed under the conditions that the pressure P c of the coating composition at a point of application of the coating composition onto the support is in a range of 0 c 2 , while liquid sealing is obtained with a composition mainly containing an organic solvent applied in advance to a coating surface of the support. The ratio of t 1 /to satisfies the relation 0.2 ≦ t 1 /t 2 20, where to represents the thickness of the coating composition before drying just after coating, and t 1 represents the length of a perpendicular line from the top end of the most downstream side back edge to a tangent drawn between the front edge and a conveyance roll on the downstream side of the coating head.
