  • Patent number: 5193293
    Abstract: An apparatus for the heat treatment of yarns in motion during various operations such as drawing or texturing includes an insulating enclosure which surrounds a heating block, the combination defining a lengthwise channel through which runs the yarn to be treated. Means for guiding the yarn through the channel is provided to ensure the desired positioning of the yarn inside the channel. The heating block consists of a unit comprising at least two cylindrical sections having different diameters and arranged in the extension of one another. The means for guiding the yarn is positioned along the length of the cylindrical sections so that the yarn may be kept at a constant distance from the surface of the cylinder of smaller diameter, with the result that the yarn passing above the smaller cylinder is heated by radiation.
