ABSTRACT:
An expansion joint for metallic foil strip heaters encasing resistive heating elements comprised of a bend formed in the metallic foil strips. The expansion joint is formed by use of a tool for passing a roller in the tool handle over a rigid forming support affixed to the tool bottom forming plate with the metallic foil strip heater placed between the roller and the forming support. The tool is then removed and a flexible metal support hose is affixed to the object to be heated with the bend in the metallic foil strips placed over this support hose. The bend is then affixed to the object to be heated on either side of the support hose.
