Patent ID: 7981476

Claim:
An apparatus for coating the outer peripheral surface of a pillar structure comprising: a holder comprising a cam and a pedestal which holds the pillar structure there between in a substantially vertical direction and rotates together with the held pillar structure on an axis of the substantially vertical direction as a common rotating axis, wherein the holder comprising the cam and the pedestal which holds the pillar structure there between with one end thereof facing downward and rotates the pedestal together with the held pillar structure on the axis of the substantially vertical direction as the common rotating axis; a supplying and coating mechanism which supplies a coating material to the outer peripheral surface of the rotating pillar structure and coats the coating material on the outer peripheral surface; a plate-like smoother, a longer side end portion of which is disposed at a given position with respect to the outer peripheral surface and which smoothes a coating surface of the coating material supplied to and coated on the peripheral surface; and a following mechanism which drives the smoother following the outer periphery of the pedestal and/or the cam so that the smoother is disposed at a given position with respect to the outer peripheral surface of the pillar structure, wherein the smoother has a smoothing plate and a sheet-like elastic body provided at the longer side end portion of the smoothing plate on a side of the pillar structure, the elastic body is disposed in such a manner that the elastic body moves so as to make an upper end portion of the elastic body contact the outer periphery of the pillar structure, the sheet-like elastic body having a hardness of 30-80 as measured in accordance with JIS K6253, and wherein the coating material is supplied to and coated on the outer peripheral surface through the elastic body, the coating material is delivered by the moved elastic body from a nozzle from the supplying and coating mechanism to the outer peripheral surface of the pillar structure, the coating surface is smoothed between the outer peripheral surface and the elastic body and the sheet-like elastic body has a thickness of 1-5 mm and a width of 1-10 mm.
