Description of the Related Art Applying various coating liquids to a support such as a plastic film or paper and drying it to obtain a desired product is used for manufacturing photographic light-sensitive materials, pressure-sensitive recording paper, heat-sensitive recording paper, etc. Widely used. However, the bead coating method,
When applying a fluid coating liquid to a web such as a plastic film or paper by using an extrusion coating method, a curtain coating method or other similar coating method,
It is recognized that a thick coating portion and a thin coating portion (low concentration) are formed at both ends of the coating layer as compared with the other coating layers. The thickly coated portions on both ends require a great deal of time and energy to dry in comparison with other normally coated portions in the drying step following coating. The portion of low density narrows the cut width of the product, and cannot cut a predetermined width, resulting in an increase in finishing process and a decrease in yield.

ため、保守点検を頻繁に行う必要がある。When the drying process does not have the ability to sufficiently dry the thick coating portion, the thick coating portion becomes undried and is transferred to a roll or the like to stain the process, or to the core in the winding process. At the time of winding, both ends adhere to each other, which causes a problem such as cutting of the web when unwinding in the cutting process. Therefore, conventionally, there has been proposed a method for preventing thick coating at both ends of the coating layer of the web. A method of sucking the thickly coated portion with a suction pipe (Japanese Patent Laid-Open No. 56-73579), or smoothing (Japanese Patent Publication No. 57-37388), and further air flow diffusion at both ends (Japanese Patent Laid-Open No. 54-14224).
No. 8), a method of separating both end portions before final drying (Japanese Patent Application Laid-Open No. 54-159452) and the like have been proposed. However, in all of these methods, a separately provided device is used to prevent thick coating portions from being formed at both ends of the coating layer, and it is expensive to install this device. Further, if these devices fail, the effect of preventing thick coating cannot be obtained, so that frequent maintenance inspections are required.

については、まだ充分な対策が無いのが現状である。Further, Japanese Unexamined Patent Publication (Kokai) No. 59-206079 discloses a method of coating with a width wider than a predetermined coating width on a slide surface, and Japanese Unexamined Patent Publication (Kokai) No. 63-144348 discloses a method of applying a surface tension lower than that of a coating solution to both ends of the sliding surface. A method of applying the liquid at a low application amount has been proposed. These methods apply a coating wider than the cutting width, reduce the yield of raw materials such as a web and a coating solution, and are wasteful. As described above, there is no sufficient countermeasure against thick coating at both ends of the coating layer.

The upper part of the coating liquid outflow width of the slit is equal to the coating width L 1 regulated by the coating width regulating plates 12 attached to both ends of the slide surface 8. The lower part of the coating solution outflow width of the slit is set to a predetermined amount narrower than the coating width L 1 regulated by the coating width regulating plates 12 attached to both ends on the slide surface 8, and the adjustment width L 3 is set. It is set.

The coating liquid 5 passes through the cavities 11a, 11b, 11c, 11d, flows into the slits 7a, 7b, 7c, 7d with the coating liquid outflow width L 2 , and flows to the outlet above the slit with the coating liquid outflow width L 1 , and slides. The surface 8 is flowed down with the coating width L 1 regulated by the coating width regulating plate 12. Both end portions 5b of the coating liquid 5 are lower than or equal to the surface of the coating liquid 5.
