Abstract
Method and apparatus for joining together edge surfaces of polytetrafluoroethylene material by a butt joint in which clamps along the abutting surfaces press together the abutting surfaces, heating means spaced from and out of direct contact with a strip between the clamps heats the strip by radiation or convection, and a cooling arrangement is provided via the clamps to remove heat from the clamping zone. A thin foil of a fluorine-containing thermoplastic inserted between the abutting surfaces facilitates joining of the surfaces.
