APPARATUS FOR COATING OUTER PERIPHERAL SURFACE OF PILLAR STRUCTURE AND METHOD FOR COATING OUTER PERIPHERAL SURFACE OF PILLAR STRUCTURE

摘要

According while supplying, applying a coating material to the outer peripheral surface (1a) of the nozzle (12b), the columnar structure (1) from, the coated surface with a smoothing means 10, the smoothing screen has a pillar-shaped structure (1) of the outer peripheral surface coating apparatus, the nozzle (12b) of the opening (12c) are substantially arranged in the vertical direction, the pillar-shaped structure length in the longitudinal direction (1) of the opening (12c) is located in its upper end so that the position substantially the same as the upper end portion (1e) of the pillar-shaped structure (1) It is formed to be shorter than the length between the both end portions. Using the outer peripheral surface coating apparatus 50 of this pillar-shaped structure (1) coating the outer peripheral surface (1a) of the pillar-shaped structure (1). According to the invention, to avoid cracks in the coating portion during drying after coating, the coating apparatus is provided with an outer peripheral surface and the outer circumferential surface of the columnar structure of the coating method capable of forming the columnar structure coating the outer peripheral surface free from defects.
