ABSTRACT:
An apparatus for controlling thickness of a coated film of paint on a continuously moving sheet member. A paint in a paint pan is picked up through a gap h.sub.PA formed between a pickup roll and an applicator roll, part of the paint is attached to the applicator roll and delivered to a sheet as a supply flow rate q.sub.A. The film thickness coated on the sheet is controlled in accordance with a model equation: M={(q.sub.A -q.sub.L)'.gamma.'C}/LS which has evaluated a difference between the supply flow rate q.sub.A and a leak flow rate q.sub.L not transferred onto the sheet, remaining on the applicator roll and escaping through a gap h.sub.AS (.XI. is the specific gravity of the paint, C the concentration of a solid content of the paint and LS a moving speed of the sheet).
