IPC: B05D1/30
Filed: 1989-12-25
Abstract: PURPOSE:To obtain a product having constant coating film thickness over the entire length of a coil by controlling the nip pressure between a coating rubber roll and a doctor roll on the basis of the detected value of the film thickness of the paint flowing along the surface of a blade. CONSTITUTION:Paint is emitted from the roll gap between a coating rubber roll and a doctor roll 21 and the paint on the coating roll 11 is scraped off by a metal blade 35 to be allowed to flow down in a curtain-like state to coat a plate material 1. At this time, the film thickness of the paint flowing along the surface of the blade 35 is detected by the non-contact type film thickness detector 37 opposed to the blade 35. On the basis of the detected value of the film thickness, the nip pressure between the coating rubber roll 11 and the doctor roll 21 is controlled. As a result, a product having constant coating film thickness over the entire length of a coil can be obtained.
