Abstract
Procédé et dispositif permettant de fabriquer des pièces en forme à partir de tubes en matière synthétique thermoplastique expansée. Pour fabriquer une telle pièce, on glisse un tube de longueur convenable 3, à l'état froid, sur une forme interne 2 correspondant à la forme voulue; on fixe les extrémités 3a, 3b du tube, par exemple au moyen de bagues de serrage 5; on recuit ensuite le tube, en place sur la forme interne, à une température correspondant à l'état thermoélastique à thermoplastique de la matiere expansée, puis on refroidit le tube et on le retire enfin de la forme interne. Application aux raccords courbés.
