A method for processing an L-shaped folded product in which folded members are joined together in an L-shape, in which a unfolded material is created by unfolding the above-described bent product, and the material has a predetermined cross section. A predetermined bending process is performed in the longitudinal direction so that the reference plane of the developed material is bent in the transverse direction to give the above-mentioned C shape.
A feature is that the bending portion in the horizontal direction of the surface is provided with grooves sufficient to allow the folding in the L-shape to be performed manually.
