Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an apparatus and a method for roller hemming which can reduce the number of times of folding while folding a flange into a predetermined shape by reliably setting a predetermined folding part as a bending point.SOLUTION: A roller hemming apparatus includes a processing roller 10 for folding a flange WF of an outer panel W1 at a predetermined folding part FO by a predetermined folding angle 1. In the processing roller 10, a round-shape part 12 for sliding a flange end FS in an inside direction of a workpiece W on a processing surface of the processing roller 10 is provided at the processing surface at which the processing roller 10 provides folding processing.
