Abstract
A method of producing a corner in thermoplastic flexible channel material having a base portion and at least one leg comprises flattening the leg portion outwardly while folding the material with a 'U' bend upon itself to provide an overlapped base and leg portion. Ultrasonic energy is applied to the overlapped flattened leg portion for simultaneously sealing and cutting the overlapped leg portion at an oblique angle to the longitudinal axis of the channel material. Upon releasing the channel material, the material is restored to its original shape, but exhibiting a formed corner.
