ABSTRACT:
Device for the heat treatment of moving yarns, during, for example, a texturizing stretching operation. The yarn is subject to two successive treatments, one at a high temperature, the other at a normal treatment temperature. The device is one wherein these successive phases are obtained by means of a heating unit formed by a cylindrical assembly comprising two heating zones on either side of which are provided guide means for the yarn. The zones are heated by means of two resistance elements embedded inside the cylindrical assembly. The two resistance elements are mounted in parallel, offset with respect to each other along the length of the unit, and each associated with a thermocouple element enabling temperature to be regulated accurately.
