For example, in the conventional cylindrical shape in which the diameter of the fixed roller (or the reinforcing bar supporting column) that receives the reinforcing bar (10 mm) to be processed is smaller than 20 mm, the anti-bending force applied to the fixing roller (or the reinforcing bar supporting column) is counteracted. Since it could not bear the force and was bent, it was not possible to bend the reinforcing bars into parallel hairpin shapes with a radial dimension (thickness) apart.
