Abstract
In a roller hemming method for folding a flange erected from a workpiece by pressing a working roller against the flange and moving the working roller relative to the flange, the flange is folded by: a first temporary bending step of bending a tip-side portion of the flange into a state that the tip-side portion is inclined; a second temporary bending step of bending a remaining, base-side portion of the flange into a state that the base-side portion is inclined; and a full bending step of bending the thus-bent flange into a final shape so that the flange is into contact with a flange-proximate portion.
