Abstract
A roller hemming apparatus includes a receiving body including a receiving member coming into contact with an edge of a panel workpiece, a roller body including a roller member bending a panel flange at the edge of the workpiece toward the receiving member, and a movement unit moving the roller body along the edge and tilts up or down the roller body toward the flange. The roller member hems the flange through the tilting-up operation of the roller body. One of the receiving and roller bodies includes a guide recess and the other includes a convex curved surface coming into sliding contact with the recess. The recess and the surface have a same curvature. The roller body is tilted up to bend the flange or tilted down to move away from the flange around a center of curvature common to the surface and the recess that come into sliding contact.
