とが困難であり、均一に塗装する為に塗液濃度を下げ、
厚く塗装すると、乾燥のため塗工速度が著しく低下する
ことになる。(Prior art) There are methods of coating (coating, spraying, etc.) a moving web with a liquid using a doctor knife coater, various roll coaters, etc., but it is difficult to apply a uniform and thin coating. , lowering the concentration of the coating liquid for uniform coating,
If a thick coating is applied, the coating speed will be significantly reduced due to drying.
走行するウェブに、均一かつ薄く塗装する方法として、

Publication) (2) Bringing one end of a cloth-like member into contact with the web, and supplying liquid from a jet nozzle to the cloth-like member as droplets with a particle diameter of O1201 to 10 μm (Japanese Patent Laid-Open No. 60-34769) Public bulletin)
It has been known.
しかし、上記従来の塗装方法は、下記の問題点を有して

塗装できない。In the coating method described in item (1) above, the foam is simply suspended in the air, and the foam itself does not actively adhere to the web. By chance, the foam traveling in the direction of the web simply adheres to the web, and the coating efficiency is low. Furthermore, if the web is non-uniformly charged, uneven coating will occur and uniform coating will not be achieved.
(2)項の塗装方法では、イfi様部材がウェブに接触
しているので、塗液は、布様部材からウェブへは効率よ
く移行するが、ジェットノズルから布様部材に供給され
る粒子は、気流によって散乱される。In the coating method described in item (2), since the ifi-like member is in contact with the web, the coating liquid transfers efficiently from the cloth-like member to the web, but the particles supplied from the jet nozzle to the cloth-like member is scattered by air currents.
従ってこの方法では、塗液が布様部材からウェブへは、
効率よく移行するが、ジェットノズルから布様部材へは
効率は悪い。Therefore, in this method, the coating liquid is transferred from the cloth-like member to the web.
Although the transfer is efficient, the transfer from the jet nozzle to the cloth-like member is inefficient.
本発明は、かかる問題点を改善し、液滴を効率よくウェ
