Abstract
Procédé pour la fabrication en continu d'un tube ou d'un faisceau de tubes équipé d'un gaine isolante, de préférence en mousse synthétique thermoplastique à pores fermés. La bande 2 en mousse synthétique est, dans le dispositif de chauffage 7, réchauffée du côté destiné à former la face interne de la gaine isolante, ceci jusqu'à l'état thermo-élastique ou thermoplastique, puis formée en gaine isolante dans le tube de formage 14, l'ébauche ainsi obtenue étant refroidie dans le dispositif 11, le tube ou le faisceau de tubes introduit dans le joint ouvert de cette ébauche, puis le joint de la gaine fermé dans le dispositif de soudage 19.Process for the continuous manufacture of a tube or a bundle of tubes equipped with an insulating sheath, preferably of closed-pore thermoplastic synthetic foam. The synthetic foam strip 2 is, in the heating device 7, reheated on the side intended to form the internal face of the insulating sheath, this to the thermo-elastic or thermoplastic state, then formed into an insulating sheath in the tube. forming 14, the blank thus obtained being cooled in the device 11, the tube or the bundle of tubes introduced into the open joint of this blank, then the seal of the sheath closed in the welding device 19.
