Abstract
Method for uniformly stretching a bundle of filaments, of a synthetic linear thermoplastic polymer having a second order transition temperature (Tg) of at least 35ºC, characterized in that it comprises passing a bundle at least partially around the peripheries of a plurality of feed rollers in series and a plurality of draw rollers in series, the latter rollers of which rotate with a greater peripheral speed characterized in that the contact in at least one of the feed rollers is treated with water at a temperature on the Tg ± scale 10ºC, the stretching being completed practically at this temperature before the beam leaves the last feed roller.
