Device for cabling and continuous fixing of wires followed by complementary heat treatment

Abstract

The device comprises: a two-for-one twisting spindle supporting a thread winding which is twisted or cabled via a second thread; a mechanism for pulling the thread in order to cancel the tension resulting from the twisting or cabling operation; a heater for heating the thread followed by a cooling area; and a mechanism for coiling the thread. Upstream from the heater, thread is subject to the action of at least one colorant.

1 . A device for the continuous cabling and setting of threads followed by an additional heat treatment, comprising: 
 a double twist or cabling spindle supporting a first thread, said first thread being twisted or cabled together with a second thread to form a twisted or cabled thread;    means for take-up of a thread in order to cancel out tension resulting from a twisting or cabling operation;    thread heating means followed by a cooling zone;    means for winding up the twisted or cabled thread; and    upstream of the heating means, means subjecting the twisted or cabled thread to action of at least one dye.    
   
   
       2 . The device as claimed in  claim 1 , wherein the heating means comprises at least one cylindrical godet associated with a return guide or roller for allowing an easing of the thread, said godet being brought to a defined temperature and being driven positively in rotation.  
   
   
       3 . The device as claimed in  claim 2 , wherein the cooling zone comprises an assembly of at least one cylindrical godet and return guide or roller ensuring the easing of the thread, said assembly being located between the heating godet and the winding-up means.  
   
   
       4 . The device as claimed in  claim 1 , wherein the heating means comprises an oven.  
   
   
       5 . The device as claimed in  claim 3 , wherein at least one godet and return guide or roller have spaced slots formed parallel to their axis of rotation.  
   
   
       6 . The device as claimed in  claim 5 , wherein a bottom of the slots is rounded so as to form grooves.  
   
   
       7 . The device as claimed in  claim 6 , wherein the grooves are distributed uniformly or not on a circumference of the at least one godet and of the return guide or roller.  
   
   
       8 . The device as claimed in  claim 6 , wherein a bottom of the grooves delimits a diameter of same value or not.
