Abstract:
A method for manufacturing profiles having different cross-sectional shapes in the height direction comprising the steps of, indexing a workpiece in the longitudinal direction, blanking a plurality of types of component members having outer contours corresponding to the cross-sectional shapes of a profile from said workpiece in a plurality of processing stages, pushing back and replacing said blanked component members into punched holes on said workpiece, sequentially ejecting said component members using said punched holes as guides, supporting said ejected component members from below, and laminating said component members into said profile by lowering said supported component members by an amount of the thickness of said component members and stopping said component members at that position every time said component members are laminated and pressure bonded in the final workpiece indexing stage.
