DISPOSITIVO PARA EL TRATAMIENTO TERMICO DE HILOS EN MOVIMIENTO, POR EJEMPLO DURANTE UNA OPERACION DE ESTIRADO DE TEXTURACION. ESTA CONCEBIDO PARA SOMETER EL HILO A DOS TRATAMIENTO SUCESIVOS, UNO A UNA TEMPERATURA ELEVADA, EL OTRO A UNA TEMPERATURA NORMAL DE TRATAMIENTO. SE CARACTERIZA EN QUE ESTAS FASES SUCESIVAS SE OBTIENEN MEDIANTE UN BLOQUE TERMICO (1) CONSTITUIDO POR UN CONJUNTO CILINDRICO QUE COMPRENDE DOS ZONAS DE CALENTAMIENTO (A,B), POR AMBAS PARTES DE LAS CUALES SE PREVEN MEDIOS DE GUIA PARA EL HILO, ZONAS OBTENIDAS MEDIANTE DOS RESISTENCIAS (R1, R2) INMERSAS EN EL INTERIOR DEL CONJUNTO CILINDRICO, MONTADAS EN PARALELO, DECALADAS UNA RESPECTO DE OTRA SOBRE LA LONGITUD DEL BLOQUE, Y ASOCIADAS CADA UNA A UN ELEMENTO TERMOPAR (TC1, TC2) QUE PERMITE UNA REGULACION PRECISA DE DICHA TEMPERATURA. 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.
