ABSTRACT:
To suppress generation of a joint when detaching an applicator roll and cylindrical substrate from each other in a simple control to form a coating film having a uniform thickness efficiently on the cylindrical substrate is provided. A coating liquid is supplied from a pan to an applicator roll via a metalling roll, the applicator roll supplied with the coating liquid and a cylindrical substrate provided so as to be close to or in contact with the applicator roll are rotated. The coating liquid is transferred from the applicator roll to the cylindrical substrate, and the cylindrical substrate is rotated in a predetermined number. Thereafter, such control is carried out that the circumferential speed V1of one of the applicator roll and the cylindrical substrate is higher than the circumferential speed V2of the other when detaching the applicator roll and the cylindrical substrate from each other.
