Of these coating methods, the rod coating method is a method of transferring an excessive amount of the coating liquid to a web and then scraping off the excessive amount of the coating liquid by a rod that is stationary or rotating to obtain a desired coating amount. Since it has a feature that a thin device can be applied at high speed with a simple device and operation,
Widely used. As an application system in the rod coating method, any method can be used, but the roller coating method, particularly the kiss coating method is most commonly used in order to take advantage of the feature of simplicity. However, in the conventional rod coating method, since the application system and the measuring system are completely independent, it is necessary to set conditions individually for coating, which is not only complicated but also requires a large space. However, it had a defect that space utilization was uneconomical.

There are three types of coating device rods used in the rod coating method: rod material having a smooth surface, as is, rod material wound with wire,
Either a rod material having a groove formed therein is used, but in most cases, a rod for a coating device in which a wire is wound around the rod material is used. A wire-wound rod for a coating device has been used for hot melt coating and coating of a relatively large coating amount. Wire diameter is 0.0
8 to 1.52 mm is used, and generally 0.0
Most of them are 8 to 0.64 mm. The coating amount can be changed by the thickness of this wire. There are several methods for digging grooves in the rod material, one of which is groove formation by rolling. In this case, the coating amount can be adjusted by changing the groove shape of the rolling die. (Japanese Utility Model Laid-Open No. 1-65671) And, in order to manufacture a rod for a coating apparatus by rolling, when two dies as shown in FIG. This is achieved by forming a groove on the surface of the die, which has the same shape as the groove on the rod surface, and in which the convex portion (A portion in FIG. 5) and the concave portion (B portion in FIG. 4) of the groove on the rod surface are reversed. Was there. (Japanese Patent Application No. 1-271816)

However, as shown in FIG.
As shown in (A) and (B), most of the rod material 2a in which a wire is wound and the coating material rod 2b in which a groove is formed in the rod material have a curvature in a portion in contact with the web 5. Therefore, when viewed in cross section, they were in point contact with the web 5 like contact points C and D. Therefore, the surface pressure (the value obtained by dividing the web tension by the contact area of the rod) is large, and when the metal material or the like is used as the web, the wear of the rod becomes a big problem. Further, in the case where two or more coating films are sequentially coated on the web, if the rod coating method is applied to the second and subsequent layers, there is a problem that the coating film of the lower layer is scraped off. These problems of wear of the rod and scraping of the lower layer were more prominent as the relative values of the web traveling speed and the rotational peripheral speed of the rod increased. For these problems, contact point C or contact point D shown in FIG.
As a method of reducing the surface pressure with a line segment in the vicinity, a method of lapping the surface projections (C and D parts) of the rod 2b for a coating device and scraping it off, or a rolling surface groove of a rolling die in advance There is a method of providing a straight portion in the concave portion, but in either case, the length of the straight portion of the concave portion of the die surface groove is limited due to the high cost and the limitation in manufacturing the rolling die.

The rod 2c was obtained. As a result of coating using the rod 2c thus processed, a good coating surface quality was obtained with a coating amount of about 25 cc / m 2 and a uniform coating amount on the entire surface of the web and in the width direction and the length direction. Furthermore, a continuous chrome coating test was performed for a long time using Al as the web 5 using a hard chrome plated rod on this rod. Similarly, the wear rate is about 1/2 that of the hard chrome plated rod (Fig. 5) 2b with no smooth surface.
Decreased to. The wear rate here is a value obtained by dividing the amount of decrease in the diameter of the rod by the coating time. Further, by using two rods (2b, 2c) similar to the rods compared in the long-term continuous coating test, the rod is driven as a method of coating the second layer on the web 5 which has been previously coated by one layer. , A reverse coating was carried out with respect to the traveling direction of the web, and the rod 2 manufactured according to the present invention was tested.
Only c could be applied without damaging the coating film of the first layer. 2 as shown in FIG. 3 (B) by the rolling process
As a method of manufacturing a rod having a surface groove shape of C, a die having a smooth surface on a part of the rolled surface as shown in FIGS. 1 (A), (B 1 ), (B 2 ), and (C) is used. In addition to the method used, a method in which the smooth portion and the grooved portion are separated and combined as shown in FIG. 2 may be used. According to this method, by changing the diameter of the smooth die, it is possible to arbitrarily change (hl) in FIG. 3 without producing a grooved die each time.

h = 0.05 mm), and as a result, the result is shown in FIG. 3 (A).
The coating device rod 2b having the same surface shape as the conventional one as shown in FIG. Rod 2 processed in this way
2B is further rolled by a rolling device having a grooved rolling die 1 and at least one smooth rolling die 7 as shown in FIG. 2B. A coating device rod 2c having a smooth portion as shown was obtained. The length of the smooth portion d can be freely and accurately manufactured by adjusting the distance between the grooved rolling die 1 and the smooth rolling die 7 shown in FIG. did it. FIG. 7 shows the relationship between the set positions (die intervals) of the uneven surface die 1 and the smooth die 7 and the smooth portion length d of the rod 2c. As a result of coating using the rod 2C processed in this way, a good coating surface quality was obtained with a coating amount of about 25 cc / m 2 and a uniform coating amount on the entire surface of the web and in the width and length directions. Further, using a hard chrome plated rod on this rod, the web 5 is
When a continuous coating test was carried out for a long time using 1
The wear rate was reduced to about 1/2 as compared with the rod (FIG. 5) 2b having the same coating amount and similarly hard-chrome plated after being manufactured by the rolling process and having no smooth portion. Further, by using two rods (2b, 2c) similar to the rods compared in the long-term continuous coating test, the rod is driven as a method of coating the second layer on the web 5 which has been previously coated by one layer. As a result of performing a test in which the coating is reversed with respect to the web traveling direction, only the rod 2c manufactured according to the present invention could be coated without damaging the coating film of the first layer. Figure 3 by rolling
As a method of fabricating a rod having a surface groove shape (B), the FIG. 2 (A), other than the method carried out in two passes (B), the Fig. 1 (B 1), ( B 2 ), an integrated die 6 may be used, or a grooved die 8 having a smooth surface, which is a combination of the rolling grooved die 1 and the smooth surface-only die 7, may be used once. The rod may be manufactured.
