Abstract
The technique of forming a jacket by welding a pair of T-shaped side rails to a U-shaped enclosure comprises the steps of (1) inserting the U-shaped enclosure over a spacer plate, (2) clamping the U-shaped enclosure to the spacer plate, (3) inserting the flange portions of the T-rails between the side edge portions of the U-shaped enclosure, and (4) ultrasonically welding the side rails to the U-shaped enclosure to complete the assembly. According to a further feature of the invention, the clamping plates are fitted with tapered inserts at both ends to oppose the tendency of the finished jacket to collapse in the middle. Pursuant to still another aspect of the invention, the portion of the spacer plate near the open end of the U-shaped enclosure is provided with energy concentrating tips to direct a portion of ultrasonic energy to this region to ensure a good weld between the side rails and the U-shaped enclosure near its open end.
