ABSTRACT:
Sheets of film-like material such as thermoplastic sheets, coated paper, or metallic foil may be clamped together for radiant energy welding by directing jets of gas against the outer surfaces of two opposed sheets to press or clamp the sheets firmly into contact with each other; and, then by irradiating the contact area to heat the material to its welding temperature, the sheets will be fused together.
