Abstract

A.LE PROCEDE EST DESTINE A LA FABRICATION DE CYLINDRES COMPOSITES DE FEUILLES DE MATIERE PLASTIQUE ET DE FEUILLES DE MATIERES FIBREUSES ETANCHES AUX LIQUIDES ET EMPECHANT LA DIFFUSION. B.LES SURFACES INTERIEURE ET EXTERIEURE DU TUBE FABRIQUE PAR LE PROCEDE SONT SUFFISAMMENT LISSES POUR SUPPRIMER LES DIFFICULTES DE SCELLEMENT DES EMBOUTS QUE L'ON APPLIQUE POUR OBTENIR UN RECIPIENT HERMETIQUE. C.CE PROCEDE SUPPRIME LES INEGALITES DE NIVEAU PRODUITES PAR LA SUPERPOSITION NECESSAIRES POUR FORMER LES JOINTS DES DIFFERENTES BANDES DE MATIERE PLASTIQUE ET DE MATIERE FIBREUSE QUI CONSTITUENT LE CYLINDRE.
