Abstract

L'INVENTION CONCERNE LA FABRICATION DE TUBES ANNELES FENDU LONGITUDINALEMENT EN MATIERE PLASTIQUE, AU MOYEN D'UN DISPOSITIF COMPORTANT UNE TETE D'EXTRUSION, UNE OLIVE FORMANT BOUCHON D'AIR, ET UN MOULE MOBILE EN DEUX SERIES DE MATRICES FORMANT LES MAILLONS D'UNE CHAINE SANS FIN ET DONNANT SA CONFORMATION AU TUBE LISSE EXTRUDE PAR APPLICATION DE CELUI-CI CONTRE LES MAILLONS SOUS L'EFFET D'AIR INSUFFLE. SELON L'INVENTION, L'OLIVE FORMANT BOUCHON D'AIR PORTE UNE PORTION EFFILEE DONT LE BORD TOURNE VERS L'AMONT EST TRANCHANT, DE FACON A FENDRE LONGITUDINALEMENT ET EN CONTINU LE TUBE ANNELE CONFORME A SA SORTIE DU MOULE. APPLICATION NOTAMMENT AU LOGEMENT DE CONDUCTEURS ELECTRIQUES, ET MEME POUR DE TRES FAIBLES DIAMETRES DE TUBES ANNELES.
