发明名称 COATING DEVICE
摘要 PROBLEM TO BE SOLVED: To prevent formation of a deposit and an aggregate even coating components which precipitate easily and/or agglutinate easily exist in coating liquid, and produce a sheet on whose main surface is coated with the coating components uniformly.SOLUTION: In a space in which coating liquid exists formed by a coating roll 1 and a coating liquid tub 2 whose inner surface is formed into an arc shape, length of the shortest distance of the coating liquid tub and the coating roll on an end of a supply side of the coating liquid, and length of the shortest distance of the coating liquid tub and the coating roll on an end of a discharge side of the coating liquid are different from each other. Thereby moving speeds of the coating liquid on both ends are different from each other, following to movement of the coating liquid in the space, shear force is applied to coating components in the coating liquid so that precipitation and/or aggregate of the coating components can be prevented effectively. In addition, a sheet on whose main surface is coated with the coating components uniformly can be produced without setting an interval of the coating liquid tub and the coating roll to be constant.
