METHOD AND DEVICE FOR COATING BAND-LIKE BODY

Document Type and Number:

WIPO Patent Application WO/2021/124714

Kind Code:

A1

Abstract:

Provided are a method and a device for coating a band-like body, which enable prevention or suppression of the occurrence of a coating failure even in an operation carried out for a long time by suppressing coagulation or adhesion of a thixotropic paint or dispersible paint in a coating pan. The present invention involves, in order to supply a coating liquid (L) into a coating pan (1): supplying a jet flow of the coating liquid (L) toward the bottom surface (4) of the coating pan (1) at a position below the liquid surface of a coating bath of the coating liquid (L), so as to generate a bottom surface flow (Fb) of the coating liquid (L) along the bottom surface (4); generating a blown-up flow (Fu) by causing the bottom surface flow (Fb) to flow upward along the inner surfaces (9, 10) of the coating pan (1) from the bottom surface (4); and causing the coating liquid (L), in an amount equivalent to the supply amount of the coating liquid (L) to the coating pan (1), to overflow from an upper end edge (6) of the coating pan (1) at the front side in the flowing direction of the bottom surface flow (Fb), to cause the coating liquid (L) in the coating pan (1) to continuously flow toward the upper end edge (6).
