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