ABSTRACT:
A coating apparatus for coating a sensitizing solution onto a surface of an elongated metal plate includes a transfer roller and a coating nozzle for coating the sensitizing solution on a circumferential surface of the roller. The circumferential surface of the transfer roller is in contact with the surface of the metal plate running in the longitudinal direction under a predetermined tension. The transfer roller is rotated in a direction opposite to that in which the metal plate is run, so that the coated sensitizing solution is transferred from the circumferential surface of the transfer roller on the surface of the metal plate.
