Abstract

Un dispositif supplémentaire de chauffage est prévu, entourant le tube et à l'aide duquel le tube (2) peut etre préchauffé sans déformation à une température inférieure à la température de cintrage, avant l'entrée dans l'anneau chauffant.An additional heating device is provided, surrounding the tube and with the help of which the tube (2) can be preheated without deformation to a temperature below the bending temperature, before entering the heating ring.
