Abstract

Filaments of synthetic organic linear polymers such as polyethylene terephthalate, are hot drawn by passing them repeatedly around a heated feed roll, thereafter over an idler roll and then repeatedly around a heated draw roll arranged coaxially with the feed roll and revolving at a higher peripheral speed than the feed roll. The feed roll and/or the draw roll may be provided with an associated idler roll. The filaments may be caused to travel over and in contact with a heated surface (such as a stationary plate heated to 150 DEG -190 DEG C.) before or after being passed over the first idler roll. The draw ratio may be 3,6:1 to 4,4:1. The feed and draw roll may constitute an integral structure of chromium plated steel. The feed and/or draw roll may be provided with an internal electric heater.
