COATING DEVICE AND COATING METHOD

To provide a coating device for forming coated films onto both surfaces of a base material which applies tension in a base material width direction.SOLUTION: A coating device 20 includes first and second blocks 21 and 22 which coat a coating liquid C to both surfaces of a base material 2 and are opposite to each other in a thickness direction of the base material 2, and a liquid reservoir part 23 which is formed so as to accumulate the coating liquid C in a gap between the first and second blocks 21 and 22 and passes the base material 2 therethrough. The liquid reservoir part 23 includes a base material introduction port 24 that is opened to the upstream side in a conveyance direction of the base material 2 and to which the base material 2 is introduced, a base material discharge port 25 that is opened to the downstream side in the conveyance direction and to which the base material 2 is discharged, and side face parts 26 positioned on both sides in a width direction. In the first block 21, a coating liquid supply port 30 for supplying the coating liquid C to the liquid reservoir part 23 is provided. In the first block 21, a coating liquid discharge port 31 for discharging the coating liquid C from the liquid reservoir part 23 is provided. The coating liquid supply port 30 and the coating liquid discharge port 31 are arranged at a mutual interval in the width direction.SELECTED DRAWING: Figure 4 【課題】基材両面に塗膜を形成する塗工装置において基材幅方向にテンションを与える。【解決手段】塗工装置２０は、基材２の両面に対して塗液Ｃを塗布し、基材２の厚み方向に互いに対向する第１及び第２ブロック２１，２２と、第１及び第２ブロック２１，２２同士の隙間に塗液Ｃが溜まるように形成されるとともに、基材２が通る液溜り部２３と、を備える。液溜り部２３は、基材２の搬送方向における上流側に開口し、基材２が導入される基材導入口２４と、搬送方向における下流側に開口し、基材２が排出される基材排出口２５と、幅方向の両側にそれぞれ位置する側面部２６と、を含む。第１ブロック２１には、液溜り部２３に塗液Ｃを供給する塗液供給口３０が設けられている。第１ブロック２１には、液溜り部２３から塗液Ｃを排出する塗液排出口３１が設けられている。塗液供給口３０と塗液排出口３１とは、幅方向において互いに間隔を空けて配置されている。【選択図】図４
