Abstract

Système d'étirage mixte comportant deux processus en continu, la première phase étant effectuée au mouillé à l'aide d'un train d'alimentation des filaments et d'un train d'étirage (2), un bain de liquide (3) et des rouleaux de guidage submergés (4) étant prévus entre ces deux éléments. La seconde phase utilise le train d'étirage (2) qui fonctionne alors comme train d'alimentation des filaments, chargés de liquide, qui sont conduits jusqu'à des moyens chauffés (6) à une température supérieure à la température de fusion desdits filaments à l'état sec, où se produit la vaporisation instantanée de la charge liquide et la stabilisation desdits filaments en coopération avec un train final (7).Mixed drawing system comprising two continuous processes, the first phase being carried out in the wet using a filament supply train and a drawing train (2), a liquid bath (3) and submerged guide rollers (4) being provided between these two elements. The second phase uses the drawing train (2) which then functions as a supply train for the filaments, loaded with liquid, which are led to heated means (6) at a temperature higher than the melting temperature of said filaments. in the dry state, where the instantaneous vaporization of the liquid charge occurs and the stabilization of said filaments in cooperation with a final train (7).
