Abstract
In order to be able to easily and sufficiently remove paint from the surface of a bumper, grooves or projections are provided on the surface of one roller, from among a pair of rollers on a roller apparatus (), that comes into contact with the surface of the paint, and the paint is divided by making cuts in the paint by means of the grooves, or the like. In addition, by making the rotation speed of one roller faster than the other roller, the abovementioned cuts are widened further and the paint is divided into a plurality of narrow, strip-shaped pieces. When a sandblasting apparatus () sandblasts towards the strips of paint, and the like, from a diagonal direction, the sandblast strikes not only the surface of the paint but the edges of the cuts as well, whereby the paint can be efficiently removed.
