Abstract

L'INVENTION CONCERNE UNE TETE D'EXTRUSION POUR LA FABRICATION D'UNE GAINE PERFOREE EN MATERIAU THERMO-PLASTIQUE. LA TETE COMPORTE UN CANAL D'EXTRUSION ANNULAIRE ET DES MOYENS DE POINCONNEMENT DISPOSES A LA SORTIE DE CELUI-CI POUR PERFORER LA GAINE. ELLE EST CARACTERISEE EN CE QUE LES MOYENS DE POINCONNEMENT COMPORTENT DES POINCONS DISPOSES LE LONG DU BORD INTERIEUR DE LA SORTIE ET MONTES A COULISSEMENT RADIAL, UNE CONTREPARTIE EN REGARD DES POINCONS, SUR LE BORD EXTERIEUR DE LA SORTIE, UN CRANTAGE DE LA PERIPHERIE DU POINCON OU DE LA CONTREPARTIE POUR Y DEFINIR DES DENTS, ET DES MOYENS POUR PROVOQUER A VOLONTE UN COULISSEMENT SIMULTANE DES POINCONS VERS LA CONTREPARTIE POUR LES METTRE EN CONTACT MUTUEL VIA LES DENTS A TRAVERS LA SORTIE, ET INVERSEMENT POUR DEGAGER LA SORTIE. APPLICATION A LA REALISATION DANS UNE GAINE DE PERFORATIONS DE FORMES ET DE DIMENSIONS VARIABLES DISPOSEES EN ANNEAUX.
