てウェブｌに塗布されることになる。For example, FIG. 5 is a schematic diagram showing an example of a bar coating device using a conventional coating rod for a coating device according to the present invention. Rod 2 is rotated. A bar support member 3 is provided over the entire length of the bar 2, and has the function of preventing the bar 2 from being bent and serving as a liquid supply device for supplying the coating liquid 4 to the bar 2. That is, the coating liquid 4 flows from the liquid supply port 5 provided in the bar support member 3 to the liquid supply guide groove 7 formed between the weir member 6 and the liquid supply port 5.
The rotating bar 2 picks up the material and applies it to the web 1, but at this time, the web 1 and the bar 2
The coating liquid 4 is measured at the contact portion with the web 1, and only the desired coating amount is applied to the web 1, and the rest flows down to form a liquid pool 8 together with the newly supplied coating liquid 4. Therefore, in a steady state, the coating liquid 4 is applied to the web 1 via the liquid reservoir 8.
この塗布方法の場合、ウェブ１の縁部が厚塗りになるの
で、厚塗り防止対策として次の様な方法が開示されてい
る。In the case of this coating method, the edges of the web 1 are coated thickly, so the following method has been disclosed as a measure to prevent thick coating.

示されている。That is, a method of scraping off the coating liquid with a blade to prevent the thickly coated portion of the web from becoming thickly coated (Japanese Patent Laid-Open No. 60-225
669 (Japanese Patent Application Laid-open No. 142248/1983), or a method of scraping off thickly coated areas with air after coating (Japanese Patent Application Laid-open No. 142248/1983).

４が付着した状態となる。However, as the coating speed increases or the flow rate increases, the coating liquid 4 may bulge on the end surface 11 of the web 1 at the upper part of the liquid pool 8 as shown in FIG. As shown in FIG. 7, the coating liquid 4 also adheres to the edge 9 of the cross-sectional surface 12 of the web 1 (referred to as the back side).
As shown in FIG. 8, a large amount of the coating liquid 4 adheres to 1, and further, as shown in FIG.

なる。In the latter case, it will naturally stain the downstream bath roll, and in the former case, the coating liquid will rise up the end surface 11 due to surface tension effects, etc., and the reverse amount will be caused by the cloth surface 1 as shown in FIG.
If the liquid spreads to the 2 side or rises to the opposite side of the fabric 12, it will stain the subsequent pass rolls and the back side of the support, and if excess coating liquid adheres to the edge of the web, the web This will result in thick coating of the edges.
