Abstract
A heating apparatus for false twisting of synthetic fiber is desired to be a non-contact type high-temperature heating apparatus from the viewpoints of efficiency and energy saving. However, in this case, it is necessary to process a long metal bar to form a long passage through which a filament passes and accommodate a long heating member in the metal bar. This processing is very difficult to do. To solve this problem, this invention has been proposed. A main body is made of metal so that the main body is constructed in the form of a tube or it is tubular and bent relative to the length of the main body. End walls are formed on both ends of the main body. In the main body, passages through which filaments pass are provided along the length of the main body and guides are provided. Further, heat-conductive powder or grain is contained in the main body and additionally, a heating member is provided therein.
