Abstract

In a process for drawing thermoplastic profiles formed by extrusion and passed through a drawing apparatus which applies vacuum and cools the section, the appts. provides at least two chambers surrounding and opening onto the profile, one of which is maintained under vacuum while the other contains a fluid, partly liquid, cooling medium. The continuous process for producing a variety of drawn calibrated profiles from tubular sections allows cooling and improved lubrication, requiring a reduced tractive force on the profile.
