摘要

Process for the hot drawing of articles of linear synthetic superpolymers such as particularly of polyethylene glycol terephthalate by which the drawing is carried out by passing the filaments and the like yarns on two rollers (an input or feed roller and a drawing roller by rotating at peripheral speeds different) and by a heating and brake device disposed between both rollers formed by at least heated rods characterized in that the filament fibers and the like are wound around the device so that they are heated on all sides.
