Abstract
A workpiece which is made by integrally combining an outer member and an inner member through hemming is manufactured efficiently in a common apparatus. An outer member and an inner member are combined to alternately subassemble two kinds of workpieces at a common subassembly station. A hemming station is disposed on a downstream side of the subassembly station in a manufacturing line. In this hemming station, a first hemming apparatus for the first kind of workpiece and a second hemming apparatus for the second kind of workpiece are disposed in a side by side relationship with each other. The first kind of workpiece subassembled in the subassembly station and the second kind of workpiece are alternately fed to the first hemming apparatus and the second hemming apparatus by a workpiece feeding robot.
