Abstract
A method and apparatus for cutting and heat sealing the ends of lengths of woven thermoplastic material is disclosed with the apparatus including selectively activated means for feeding predetermined lengths of a material from a supply across the supporting surface. Means releasably clamp the material lengths against the supporting surface, with a gap extending transversely of the material lengths to expose portions of the material through the gap. A laser beam is directed against the exposed portions of the material, with the laser beam being moved transversely of that material along the gap and removing the material exposed to the laser beam and heat sealing the portions of the material immediately adjacent that removed.
