ABSTRACT:
A chemically washed workpiece is heated and degreased by a heating and degreasing section in a process for delivering the workpiece in a base which is then cooled down in a cooling section. The workpiece is then delivered onto the base by a lift-up unit and is coated by the adhesion of the powder coat and the curing operation during the passage of pipes of an electrostic coater, a curing section and the like. Furthermore, the workpiece is again delivered into the base by a lift-down unit and discharged after being cooled down during the passage of pipes of the cooling section i.e., the units of each step being arranged separately into a lower mechanism group and an upper mechanism group, and the cooling section also serving to cool the workpiece after the heating, degreasing and curing. Accordingly, the overall length of the apparatus is shortened. Also, since the electrostic coater, an workpiece outer circumference cleaner and the cuing section are covered by independent dust protecting covers, dust collecting efficiency for the floating powder coat is enhanced.
