    摘要： A method of making a luggage case including the steps of forming a pair of frame members adapted to abut in interlocking relationship, attaching the material which, together with the frame members, forms the peripheral surface of the case to said frame members while they are in a substantially linear condition, bending the framework and the material attached thereto to the required shape of the outer periphery and attaching to the resulting peripheral surface the side panels, lining and other necessary accoutrements. The luggage case resulting from the method of construction has no passage for dirt, water and the like to enter the luggage case at the place where the framework is attached.

    摘要： A METHOD AND APPARATUS FOR FORMING A SHADOW MASK FRAME HAVING A DISH-SHAPED WALL POSITIONED OBLIQUELY WITH RESPECT TO THE LONGITUDINAL AXIS OF THE FRAME. THE SHADOW MASK FRAME IS FORMED BY APPLYING COLUMNAR FORCE TO A WALL OF A WORKPIECE IN A DIRECTION PARALLEL TO THE LONGITUDINAL AXIS CAUSING COMPLETE PLASTIC DEFORMATION OF THE FRAME. SIMULTANEOUS TO THE STEP OF APPLYING FORCE, A SECOND WALL OF THE WORKPIECE IS CONTAINED WITHIN A PAIR OF CONCAVE CONVEX COMPLEMENTARY SIZED DIES SO AS TO FORM A DISH-SHAPED CONFIGURATION. THE APPARATUS HAS A TOP DIE WITH STUFFING LEDGE MOVABLE TOWARD A BOTTOM DIE WITH A CONVEX PORTION. THE STUFFING LEDGE FORCES THE WORKPIECE BETWEEN THE COMPLEMENTARY SIZED DIES THEREBY FORMING THE DISH SHAPE. SIMULTANEOUSLY, A PUNCH PASSES THROUGH THE WORKPIECE AND IS HELD THEREIN DURING THE PLASTIC DEFORMATION TO ACCURATELY SIZE THE OPENING OF THE SHADOW MASK FRAME.
