A panel serving as a work object is disposed onto a die face (1a) of a hemming die (1) and pre-hemming (preliminary bending) and hemming (main bending) processes are carried out with a hemming roller held by a robot. A nesting mechanism (6) for positioning the panel is provided on a side wall part (1b) of the hemming die (1). The nesting mechanism (6) is constructed such that a movable nesting block (8) having a nesting claw section (8b) at the tip end is supported by a holder (7), the nesting block (8) being elastically supported retractably in the vertical direction (direction of arrow P1) and slidably (or tiltably) displaceable in the direction of arrow P2. Thus, interference between the hemming roller and nesting mechanism (6) has no bad effects on hemming process quality. |
