摘要： The method of making extruded metal valances for luggage which includes steps of extruding male and female valance cross sections integrally edge-to-edge, welding the extrusion into a closed loop, expanding the loop to the desired size and shape, with accompanying bending, severing the extrusion at the joined lateral edges to form mating male and female valances, and then reversing the order thereof for assembling in mating relation. The procedure includes heat treating and anodizing as a preliminary step before the extrusion is cut and formed and the piercing of any necessary holes or lugs while the extrusion is still in a single, easily handled piece and prior to severence.
