Abstract

PURPOSE:To eliminate the generation of painting irregularity by making at least three sets of support rollers each composed of a pair of rollers arranged on a base stand so as to be divided in the axial direction of a pipe to be coated selectively replaceable between the contact position with the pipe and a position spaced apart from the pipe. CONSTITUTION:A pipe M to be coated is transported to a base stand 1 by a crane to be supported by support rollers 4A, 4B, 4N raised to a contact position and the support rollers are rotationally driven by a motor. As a result, the pipe M is rotated in the peripheral direction thereof and, in this state, paint (a) is supplied to the outer peripheral surface of the pipe M from a paint feeder 21 to be applied thereto. At this time, when the paint feeder 21 is ready to reach the position corresponding to the support rollers 4A, only the support rollers 4A are allowed to be spaced apart from the pipe M. When the piston rod 12 of a cylinder device 9A corresponding to the support rollers 4A is attracted to revolve a support arm 6, the support rollers 4A are displaced to be set to a speced-apart position.
