Abstract

PURPOSE:To bend a shape material with high precision, by applying the shape material, where spacers consisting of semirigid plastic are inserted to grooves, to the side face of a bending mold and pressing a press plate to wind the shape material around the bending mold. CONSTITUTION:A shape material 4 is cut to a prescribed length, and spacers 14 and 15 consisting of semirigid plastic are fitted into an attaching groove 9 and a mounting groove. This shape material 4 is inserted to a groove 17 of a bending mold 16 having a prescribed curvature, and a press plate 18 is applied to the outside of the shape material 4, and the plate 18 is pressed from the direction of a prescribed bending work angle alpha to wind the shape material 4 around the mold 16. For example, a roller 19 is moved in the direction of an arrow to press the plate 18 in this manner. In this case, the work angle alpha is given as the sum of a bending angle beta and a spring back angle gamma. Similarly, various bending molds are used to bend the shape material 4 successively as required.
