  • Laser sealing of thermoplastic material
    Patent number: 4224096
    Abstract: Thermoplastic materials, particularly material in sheet form, may be sealed or thermowelded together using the energy from a single laser beam source by splitting the beam and directing it by mirrors to desired seal areas on the opposed sides of the materials to be sealed. The beam may be split in proportion to the thickness of the respective materials. Heating the opposed sides of materials to be sealed avoids the problem of overheating or burning the side to which energy is applied.
    Type: Grant
    Filed: March 25, 1976
    Date of Patent: September 23, 1980
    Assignee: W. R. Grace & Co.
    Inventor: Richard F. Osborne
  • Clamping of film-like material for radiant energy welding
    Patent number: 3997385
    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.
