Title (DE) ELEMENT EINES MUFFENROHRSYSTEMS UND VERFAHREN ZU SEINER HERSTELLUNG
(EN) ELEMENT OF A SOCKET-PIPE SYSTEM, AND PROCESS FOR MANUFACTURING IT
(FR) ELEMENT D'UN SYSTEME DE TUYAUX A MANCHONS ET PROCEDE POUR SA FABRICATION
Abstract:
(DE) Mit mindestens einer Muffe (10) versehene Elemente (12a, 12b) eines Muffenrohrsystems werden aus einer plastifizierten Masse aus vermischtem Abfallkunststoff, insbesondere aus dem Hausmüllbereich, in einer Formpresse hergestellt. Dadurch kann nicht nur der Bereich der Muffe (10) verstärkt werden, es können auch verstärkende und/oder das Rollen von Rohren verhindernde Profilierungen (20) an der Außenseite der Elemente vorgesehen werden.
(EN) In the invention proposed, elements (12a, 12b) of a socket-pipe system with at least one socket joint (10) are manufactured in a moulding press from plasticized material made of mixed waste plastic, in particular waste plastic from household rubbish. Not only does this give a stronger socket joint (10), but also enables reinforcing and/or anti-roll ribs (20) to be provided on the outside of the elements.
(FR) On fabrique dans une presse de moulage des éléments (12a, 12b) munis d'au moins un manchon (10) à partir d'une matière plastifiée à base d'un mélange de matière plastique de rebut, provenant en particulier de déchets ménagers. Ceci permet non seulement de renforcer la zone du manchon (10), mais aussi de prévoir, sur la face externe des éléments, des profilages (20) renforçants et/ou empêchant les tuyaux de rouler.
