Abstract
A roller having a crown shape is manufactured by pulling up a roller base having a uniform outer diameter from a paint tank at a vertical posture in such a manner that a pulling-up speed is changed in accordance with positions in an axial direction of the roller base to change a thickness of a paint coating adhered to the roller base.
Claims8
A method of manufacturing a roller having a crown shape by subjecting a peripheral face of a roller base to a dip-painting to make an outer diameter in a central portion of the roller base thicker than that in an end portion thereof, characterized in that when a roller base having approximately a uniform outer diameter is dipped in a paint tank over a full length while rendering a center axial line of the roller base into substantially a vertical posture and pulled up from the paint tank, a pulling-up speed is changed in accordance with positions in an axial direction of the roller base to change a thickness of a paint coating adhered to the roller base.
