Abstract

An electrically heated blade, for cutting or welding thermoplastic and similar heat-sensitive strips or sheets, comprises a metal blade divided by a longitudinal slot into two arms connected at one end only, the free ends of the arms being connected to the electrical source. If used for cutting, the front cutting edge may be a much thinner arm than the rear edge, so that it becomes hotter; if used for welding, both arms are of the same approximate thickness.
