Abstract
(EN)
Disclosed is a coating apparatus which is capable of maintaining good wipe-off properties, while reducing the amount of water absorbent sheets consumed. Specifically disclosed is a coating apparatus (100) for applying a solution to a substrate (90) by an inkjet system, which comprises a head unit (10) that contains a nozzle (12) for ejecting the solution to the substrate (90) and a wiping unit (20) for wiping the nozzle (12) in the head unit (10). The wiping unit (20) has a wipe-off unit (20a) for wiping off the ejection surface (12a) of the nozzle (12), and the wipe-off unit (20a) includes a blade portion (21) for scratching off the solution remaining on the ejection surface (12a) and a water absorbent sheet portion (22) for absorbing the solution remaining on the ejection surface (12a). The height (21t) of the blade portion (21) is lower than the height (22t) of the water absorbent sheet portion (22).

L'invention porte sur un appareil de revêtement, qui est apte à maintenir de bonnes propriétés d'essuyage, tout en réduisant la quantité de feuilles qui absorbent l'eau consommées. Il est décrit de façon spécifique un appareil de revêtement (100) qui permet d'appliquer une solution à un substrat (90) par un système à jet d'encre, qui comprend une unité de tête (10) qui contient une buse (12) pour éjecter la solution vers le substrat (90) et une unité d'essuyage (20) pour essuyer la buse (12) dans l'unité de tête (10). L'unité d'essuyage (20) comporte une unité d'essuyage (20a) pour essuyer la surface d'éjection (12a) de la buse (12), et l'unité d'essuyage (20a) comprend une partie de lame (21) pour racler la solution restant sur la surface d'éjection (12a) et une partie de feuille qui absorbe l'eau (22) pour absorber la solution restant sur la surface d'éjection (12a). La hauteur (21t) de la partie de lame (21) est inférieure à la hauteur (22t) de la partie de feuille qui absorbe l'eau (22).
