Abstract: A method of rotating and transferring hollow cylindrical workpieces without causing the outer surfaces of such workpieces to come into contact with each other and a non-contact method of coating hollow cylindrical workpieces which are rotated and transferred, characterized in that flanges having bores in the central portions thereof are fitted over both end portions of each hollow cylindrical workpiece, a shaft being inserted through the bores in these flanges and supported horizontally together with the workpiece at each end on and rotated by a plurality of paired vertically movable rollers which are spaced by a distance not shorter than the length of the workpiece, a pusher for moving the workpiece being provided on a shaft, a coating mechanism being provided at an intermediate portion of the shaft in order to coat the workpiece with a material, a plurality of flanged workpieces being moved by the pusher toward a discharge end of the shaft and removed therefrom in order.
