COATING MATERIAL SUPPLY LINE FOR DF COATER AND COATING MATERIAL SUPPLY METHOD FOR DF COATER

WIPO Patent Application WO/2012/020477

A1

A coating material supply line for a DF coater and coating material supply method for a DF coater are provided which do not cause streak defects on the coating film of base materials. The coating material supply line for a DF coater supplies a coating material onto a DF coater head (11), the head being equipped with a nozzle (40) that allows the coating material (Q) to flow downward in a curtain film shape, wherein a flushing water open/close valve (21a) is provided on the upstream side of the DF coater head (11). This flushing water open/close valve (21a) supplies flushing water (W) to the nozzle (40) instead of the coating material (Q). During the initial stage in which the coating material (Q) is allowed to flow downward in a curtain film shape from the nozzle (40), the flushing water open/close valve (21a) opens, supplying flushing water (W) to the DF coater head (11).
