PURPOSE: To uniformize the spacing distance between a cylindrical body and a coating head in a circumferential direction and to prevent the inclination of the cylindrical body by providing at least three pieces of rollers, which are freely rotatably held on supporting members and come into contact with the outside surfaces of the cylindrical body, nearly at equal intervals in the circumferential direction of the cylindrical body and at least two pieces thereof at spaced intervals in an axial direction.
CONSTITUTION: Total six pieces of the supporting members 20, 21 are fixed in the positions of three points at the equal intervals in the circumferential direction and two points at the spaced intervals in the axial direction in the lower part of the coating head 10. The positioning rollers 30, 31 are held freely rotatably at the bottom ends of the respective supporting members 20, 21 and are so disposed as to come into contact with the outside surface of a hollow drum 1. The central axis of the hollow drum 1 is so regulated as to align to the central axis of the coating head 10 by the rollers 30, 31 at this time and the spacing distance between the hollow drum 1 and the coating head 1 is uniformized with respect to the circumferential direction. Further, the rollers 30, 31 are disposed in height positions H1, H2 and, therefore, the hollow drum 1 is regulated in both the upper and lower positions, by which the inclination thereof is prevented.
