Abstract

A.LA PRESENTE INVENTION A POUR OBJET UNE FORME PARTICULIERE DE MISE EN OEUVRE DU PROCEDE ET DU DISPOSITIF SELON LE BREVET PRINCIPAL, POUR LA FABRICATION DE CHEVILLES TUBULAIRES EN MATIERE THERMOPLASTIQUE A PARTIR D'UN BOUDIN TUBULAIRE REALISE PAR EXTRUSION ET DECOUPE EN TRONCONS A CHACUN DESQUELS ONT FAIT ENSUITE SUBIR UNE OPERATION DE REPRISE CONSISTANT A REALISER UNE COLLERETTE A L'UNE DES EXTREMITES PAR FORMAGE DE CELLE-CI DANS UN MOULE EN ECHAUFFANT EN MEME TEMPS LA MATIERE DE CHAQUE TRONCON. B.CONFORMEMENT A LA PRESENTE INVENTION, ON REALISE CETTE OPERATION ENTRE UNE ENCLUME FIXE 20 ET UN ORGANE MOBILE DE PRESSION 23 ANIME DE VIBRATIONS ULTRASONORES QUE L'ON APPLIQUE SUR L'EXTREMITE DU TRONCON 4 DE BOUDIN TUBULAIRE DEVANT COMPORTER UNE COLLERETTE. CECI ASSURE L'ECHAUFFEMENT DE LA MATIERE DE CETTE EXTREMITE SOUS L'EFFET DES VIBRATIONS ULTRASONORES AINSI TRANSMISES. OR, CES DEUX PIECES FORMENT ENTRE ELLES, APRES REUNION, UNE CAVITE CORRESPONDANT A LA COLLERETTE A REALISER, CE QUI PERMET D'OBTENIR LE MOULAGE DE CELLE-CI. C.CE PROCEDE ET CE DISPOSITIF PERMETTENT DE FABRIQUER DES CHEVILLES A COLLERETTES EN PARTANT D'UN BOUDIN TUBULAIRE EN MATIERE THERMOPLASTIQUE.
