ABSTRACT:
Adjusting method and apparatus for a cylindrical article peripheral surface coating machine characterize in that a coating clearance between a coating roller and a cylindrical article fitted over each mandrel on a travelling mandrel conveyor, the coating clearance being formed for allowing the coating roller to be brought into rolling contact with the cylindrical article when the latter has entered the coating zone, a transfer clearance between the coating roller and a transfer roller formed for allowing the latter to be brought into rolling contact with the former, and a receiving clearance between the transfer roller and a fountain roller formed for allowing the latter to be brought into rolling contact with the former, are made adjustable each independently without affecting each other. In addition, for expanding the said coating clearance in the event the said mandrel should approach the coating zone without carrying thereon the said cylindrical article, the said coating roller, transfer roller and fountain roller are pivotally displaced on concentric arcs integrally and collectively without causing any change in the said transfer and receiving clearances. And the said transfer clearance is disposed lower than the line connecting the center of the coating roller with the center of the said collective pivotal displacement whereby the mandrel conveyor is prevented from being stained with a coating solution which scatter from the transfer clearance.
