ABSTRACT:
An interlaced meshed resistance network having one or more continuous wire conductors is formed from a tubular wire network cylinder folded over itself in order to have a double thickness into a flat annular ring shape. The resistance network can be used to bond heat fusing plastic tubes together. The wire is covered with a layer of material which is thermally conducting and electrically insulating up to a temperature about 300 to 350 degrees Celsius.
