Abstract
A heated high pressure air and/or a high pressure water are spouted through nozzles. Therefore, the coated layer is removed without crushing the bumper unlike in the conventional method, and therefore, a plurality of process steps can be skipped. Thus the bulk of the apparatus can be reduced, the operating cost can be lowered, and the environment can be protected. The method for removing a coated layer includes the step of installing a bumper to be subjected to a removal of the coated layer. Then the coated layer is removed from the bumper by spouting water and/or a pre-heated air to the bumper. Then the bumper is carried to a predetermined psition after removing the coated layer, and then the bumper is detached. The apparatus includes an installing/detaching means for installing/detaching the bumper to be subjected to a removal of the coated layer. A spouting device spouts a compressed air to the bumper thus installed to remove the coated layer from the bumper, and an air supplying means and a water supplying means respectively supply air and water to the spouting device. Then a carrying means carries the bumper to a predetermined position after the removal of the coated layer.
