Abstract

L'INVENTION CONCERNE UN DISPOSITIF A DOIGTS DE RABATTEMENT DE PLIS POUR UNE MACHINE DE FABRICATION DE PNEUMATIQUES. LES DOIGTS 13 SONT MONTES ENTRE UN ANNEAU INTERIEUR 11 ET UN ANNEAU EXTERIEUR 12. L'UN DE CES ANNEAUX EST REALISE DANS UN ELASTOMERE AYANT DES PROPRIETES MECANIQUES COMPRISES ENTRE CELLES DES CAOUTCHOUCS ET CELLES DES MATIERES PLASTIQUES. POUR DEMONTER UN DOIGT 13, IL SUFFIT DE RETIRER LES VIS DE MONTAGE LES PLUS PROCHES DE CE DOIGT ET SE TROUVANT DE PART ET D'AUTRE DE CE DERNIER, PUIS DE DEFORMER L'ANNEAU EN ELASTOMERE AFIN DE L'ELOIGNER DU DOIGT 13 SUR UNE DISTANCE SUFFISANTE POUR PERMETTRE L'ENLEVEMENT DE CE DERNIER ET LA MISE EN PLACE D'UN DOIGT DE REMPLACEMENT. DOMAINE D'APPLICATION: FABRICATION DE PNEUMATIQUES.
