Abstract: PROBLEM TO BE SOLVED: To provide a coating film manufacturing method quickly stabilizing a film thickness at the start of coating of a flexible support having high bending rigidity.SOLUTION: A control part 8 conveys a flexible support 2 by tension control. The control part 8 is configured to rotate a main speed roll 3 at a predetermined constant circumferential speed and to control the circumferential speed of a driven roll 4 so that tension of the flexible support 2 measured by a tension meter 6 becomes a predetermined constant value. Coating liquid is then discharged from a discharge port 51, a coating head 5 is moved toward the flexible support 2, and the discharge port 51 is brought into contact with the flexible support 2. After the discharge port 51 is in contact with the flexible support 2, the coating head 5 is further pressed into the flexible support 2 by a predetermined distance. After the coating is started and after tension variation of the flexible support 2 is stabilized, switching from the tension control to ratio control is performed.

Abstract: PROBLEM TO BE SOLVED: To easily change a coating width in a die coater.SOLUTION: A shim member is sandwiched by two die blocks which are possessed by a die and arranged so as to oppose each other so that a slot being a discharge port of a coating liquid may be formed at the tip of the die arranged at a die coater, and formed into such a U-shape as to be opened at the slot side. The shim member is characterized in that: the member is formed into the U-shape by a base end arranged so as to extend in the longitudinal direction of the slot and a pair of extensions extending toward the tip of the die from both ends of the base end in the longitudinal direction; and the tip of at least one extension out of the pair of extensions or a first portion being the whole of the one extension and a second portion being a remaining portion at least including the base end are constituted so as to be dividable.

Abstract: PROBLEM TO BE SOLVED: To provide a method of forming a multilayered film without causing any fine coating unevenness in the formation of a resin layer by applying a plurality of coating liquids different in viscosity. SOLUTION: A resin layer forming apparatus is provided with: back-up rollers 13, 23 for transporting a film at a prescribed speed; a coating means for discharging the resin coating liquid to the film on the surface of the back-up roller; and supply rollers 11, 21 for supplying the film to the back-up rollers. In the resin layer forming apparatus 100 for forming a resin layer using a most viscous resin coating liquid, the film transporting speed of the supply roller 11 nearest to a coating means is fixed to a prescribed value, the film transporting speed of the back-up roller 13 is controlled to follow the supply roller 11 and the film transporting speed of the supply roller 21 in other resin layer forming apparatus 200 is controlled in proportion to the expansion and contraction of the film.
