Description
【発明の詳細な説明】 本発明は、塗布物の製造方法に関するものである。[Detailed description of the invention] The present invention relates to a method for producing a coated article.
一般に、写真フィルムベース等の被塗布物に塗布液を塗
布すると表面張力の影響で縁の肥厚した塗布層ができる
。Generally, when a coating liquid is applied to an object to be coated such as a photographic film base, a coating layer with thick edges is formed due to the influence of surface tension.
この肥厚した縁の存在は、塗布層全体の乾燥を著しく遅
らせる。このため過大な乾燥能力が必要となる。また、
この縁を十分に乾燥させないで未乾燥の状態で搬送する

られている。The presence of this thickened edge significantly retards the drying of the entire application layer. For this reason, excessive drying capacity is required. Also,
If this edge is not sufficiently dried and is transported in an undried state, the coating liquid on the edge may adhere to the transport roller and peel off, or if the coated material is wound around the roller before this edge is sufficiently dry. If the edge adheres to the preceding part and is unrolled in the subsequent cutting process, problems such as the coated material being cut may occur. As a means to eliminate these inconveniences, there is a method in which the surface to be coated is wetted while blowing steam to both ends of the coated object to spread the coating solution, and a method in which heated air is applied to only the edges of the coated layer in addition to normal drying. A method of forcibly drying by spraying is known.

とである。However, these methods require expensive equipment and are very cumbersome to operate. As a technique to eliminate such inconveniences and inconveniences, a method was proposed in Japanese Patent Publication No. 52-38407 to suck up the coating liquid at the edge of the coating layer using a coating liquid suction pipe (suction nozzle) equipped with a heat insulation jacket.
It is known from the publication no. However, with such devices, the nozzle tip of the coating liquid suction pipe often gets clogged due to adhesion of the coating liquid during long coating operations, resulting in the problem that the device cannot perform adequately. found. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a method for removing coating liquid from a thick film portion at the coating edge without clogging the nozzle tip due to sticking of the coating liquid even during long-term coating.

て達成される。The object of the present invention is to provide a coating product that applies a coating solution to an object to be coated to form a coating layer, absorbs the coating solution from the edge of the coating layer before the coating layer dries, and then dries the coating layer. In the manufacturing method, liquid is ejected from the center of a suction nozzle that sucks up the coating liquid onto the thick coating area, and this liquid and the coating liquid in the thick coating area are both sucked into the suction nozzle. be done.

うるようにしている。1 and 2, a suction nozzle 1 has a suction opening 2 at one end, a drainage opening 3 at its side, and a liquid ejection nozzle 4 disposed inside the suction nozzle 1 on the bottom wall 5 of the suction nozzle 1.
By screwing together the female thread 7 provided near the outer rear end of the liquid ejection nozzle with the female thread 6 provided in the , and rotating the liquid ejection nozzle 4 with respect to the suction nozzle 1, the suction opening 2 and liquid ejection are connected. The distance between the nozzle 4 and the liquid spout 8 can be adjusted as desired.

について説明する。Three female screw holes 9 are provided in the side wall of the suction nozzle, and three adjusting screws 10 are screwed into these holes to press one end of the adjusting screw 10 to the outer wall of the liquid jet nozzle 4. When each of the three adjusting screws 10 is rotated, it moves in its axial direction, so that the relative position between the suction opening 2 and the liquid spout 8 of the liquid spout nozzle 4 can be adjusted.Liquid spout nozzle The tip on the opposite side of the liquid ejection hole 8 of No. 4 can be connected to a pipe for introducing hot water.The tip 1a of the suction nozzle 1 is detachable by being screwed into the main body 1b of the suction nozzle 1. The dome-shaped part 10 of the tip part 1b is made of transparent material barb for convenient monitoring of the inside.Next, a photosensitive material having a constituent layer containing gelatin is produced by gelling and drying the applied layer. We will explain how to apply this device in this case.

通りである。After applying the coating liquid and before the drying process, as shown in FIG. The suction nozzle of the present invention is fixed at a position where the liquid ejection nozzle 4 can be
The rear end and the liquid storage container to be supplied are connected by a conduit to the outlet of the pump, and the drainage opening 3 is connected to a pressure reducing device. With this arrangement, if hot water is sent to the liquid ejection nozzle 4 and suctioned from the liquid drainage opening, the coating liquid in the thick film part of the application section moving just in front of the suction opening 2 will be ejected from the liquid ejection nozzle 4. The hot water is sucked from the suction opening 2, and the coating liquid in the thick film portion at the coating edge is removed. A certain amount of flow rate can be maintained even if the liquid jet nozzle is simply connected to the hot water tank through a conduit without being connected to the discharge port of the pump. The conditions at this time can be easily determined by experiment, and an example is as follows.

This method has the advantage that the suction opening does not become clogged when removing the coating liquid from a thick film portion that is coated with a coating liquid that is easily solidified.
