Abstract
In order to provide a heating mantle so composed that fixing and unfixing work can be carried out simply and easily and in addition a good thermal uniformity can be obtained, the heating mantle is fabricated by a method, by which sewing by means of a sewing machine is carried out on a sheet-shaped heat resistant and heat insulating core member, using a heating wire, which is a yarn of metal fine wires, for a lower yarn and a glass yarn for an upper yarn; a predetermined heating wire pattern is formed on a surface of the core member; and a layered body consisting of the core member with the heating wire and covering members made of glass cloth, which are laid on upperside and underside thereof, is enclosed by a sack-shaped cover member. By the heating mantle thus constructed winding around a piping is simple and easy and there is no risk that deviation of the heating wire takes place so that a good thermal uniformity with respect to the piping can be exhibited. Moreover, owing to the fact that the heating wire is used for the lower yarn for the sewing machine, it is possible to form easily the predetermined heating wire pattern.
