Abstract

A roll stamping apparatus includes sets of rollers rotating while facing each other so as to press opposite surfaces of a material which is continuously supplied to move between the rollers; and molding portions having a stamping structure applied to outer surfaces of the sets of rollers so as to mold the material, wherein a plurality of sets of rollers are disposed in a movement direction of the material, the molding portions of the sets of rollers are formed to sequentially change a cross section of the material in the movement direction of the material, wherein at least one of the sets of rollers before a final set of rollers through which the material finally passes is a set of over-molding rollers having molding portions of which a length in a circumferential direction is longer than a length of the molding portions of the final set of rollers.
