Abstract
A product intermittently having a bent portion which curves three-dimensionally and a quenched portion is manufactured by performing bending downstream of a support means while feeding a metal material which is supported by the support means from an upstream side towards a downstream side. A portion of the metal material is heated by a heating means downstream of the support means. A bending moment is imparted to the portion of the metal material heated by the heating means to three-dimensionally change the position of a movable roller die which is disposed downstream of the heating means and has a plurality of rolls which feed the heated metal material in the axial direction, and the metal material is quenched by spraying a cooling medium at the portion of the metal material which was heated by a cooling means disposed between the heating means and the movable roller die.
