Abstract
Process for the continuous and uniform stretching of synthetic high linear polymer yarns that are in the glassy state at room temperature, and preferably those of poly (ethylene terephthalate), characterized by the fact that the unstretched yarn, which is uncoils in a coil, is placed in several turns around a uniformly driven roller, thus heating to 60 - 85º c, and then passing with a return angle of less than 180º on a rounded edge, heated to 95 - 150º c, for a path of less than 15 mm, after which it is removed, with or without further pre-heating, by a roller that rotates more quickly in an adjustable relation.
