Abstract:
1. An apparatus for applying a coating liquid to a cylindrical substrate by transferring the coating liquid supplied to an applicator roll from the applicator roll to the cylindrical substrate, comprising: an applicator roll; coating liquid supplying means for supplying a coating liquid to the applicator roll; mounting means for mounting a cylindrical substrate removably thereon; first driving means for rotating the cylindrical substrate mounted on the mounting means; second driving means for rotating the applicator roll; first circumferential speed detecting means for detecting a circumferential speed at which the cylindrical substrate is rotated; second circumferential speed detecting means for detecting a circumferential speed at which the applicator roll is rotated; rotation number detecting means for detecting a number of rotations of the cylindrical substrate; detaching means capable of moving the cylindrical substrate so as to be close to or away from the applicator roll; and controlling means for controlling, in response to a detection output from the rotation number detecting means, a detection output from the first circumferential speed detecting means and a detection output from the second circumferential speed detection means, an operation of the detaching means so as to move the cylindrical substrate away from the applicator roll, and an operation of the first and the second driving means so that a circumferential speed of one of a circumferential speed at which the cylindrical substrate is rotated and a circumferential speed at which the applicator roll is rotated is higher than a circumferential speed of the other of the circumferential speed at which the cylindrical substrate is rotated and the circumferential speed at which the applicator roll.
