Abstract

A device and a method for hemming processing capable of solving such a problem with a hemming processing applied along the peripheral edge of the door panel of a car that the shortening of a processing time was difficult since the flange-formed bent part was first bent by approx. 45°by a preliminary bending and then the attitude of a bending roller was changed, and the bent part was rolled again for finish bending, the method comprising the step of rolling the bending roller (R) along the bent part (We) in the attitude of the rotating shaft (R3) of the bending roller (R) tilted in a direction for delaying a bent tip side (Wee) relative to a normal line (R2) orthogonal, in plan view, to the rolling direction (R1) of the bending roller (R), whereby, since the device can bend the bent part (We) while providing a side pressure in bending direction, the device can bend the bent part (We) in folded back state by one bending process, namely since the hemming processing is completed merely by one rolling of the bending roller, the processing time can be remarkably shortened.
