Coating apparatus.

摘要

A work is applied with a solvent-containing thermosetting coating composition to a thickness larger than a limit thickness over which the coating composition on a surface of the work extending in a vertical direction will normally run or sag in a coating zone. After applied with the coating composition, the work is rotated about a substantially horizontal axis to prevent the coating composition on the vertical surface of the work from running or sagging and is conveyed through a heat-hardening zone for hardening the coating composition applied to the work by heating by a conveyor line. The conveyor line includes a pair of conveyors which are separated from each other upstream of a position where the coating composition is applied to the work to a thickness larger than said limit thickness. The heat-hardening zone includes a pre-heat-hardening zone for half hardening the coating composition and a main heat-hardening zone for fully hardening the coating composition after the coating composition is half hardened. A pooling zone in which a predetermined number of works can be temporarily pooled is provided between the pre-heat-hardening zone and the main heat-hardening zone. <IMAGE>
