Abstract

CE PROCEDE EST DESTINE A LA FORMATION DE COUCHES DE REVETEMENT INTERNES POUR LA PRODUCTION DE PNEUMATIQUES, SE COMPOSANT D'AU MOINS DEUX COUCHES DE MATIERES DIFFERENTES. UN PRODUIT EN FORME DE TUBE SOUPLE 2, FORME D'AU MOINS DEUX COUCHES, EST FABRIQUE PAR EXTRUSION EN UNE SEULE OPERATION OU EN PLUSIEURS OPERATIONS IMMEDIATEMENT CONSECUTIVES, SA PAROI ETANT ONDULEE DANS L'EPAISSEUR, C'EST-A-DIRE QU'ELLE PRESENTE DES EPAISSISSEMENTS ET DES AMINCISSEMENTS SE REPETANT A INTERVALLES REGULIERS; LES SEGMENTS (2, 2, 2) DE TUBE SOUPLE AINSI FORMES SONT ALORS DETACHES DU TUBE SOUPLE EN (3, 3, 3), POUR CONSTITUER LES COUCHES DE REVETEMENT INTERNES INDIVIDUELLES. CE PROCEDE PEUT ETRE REALISE DANS UNE LARGE MESURE AVEC DES MACHINES AUTOMATIQUES, CE QUI PERMET D'OBTENIR UNE QUALITE INATTEIGNABLE JUSQU'ICI DES ELEMENTS DE PAROI DE PNEUMATIQUE ET, EN OUTRE, D'ECONOMISER DANS UNE MESURE SUBSTANTIELLE LES MATIERES PREMIERES.
