Abstract

La présente invention concerne un appareil (1) de moulage de tuyau qui utilise de multiples alimentations de plastique permettant de fabriquer un tuyau à double paroi. Cet appareil comprend une filière possédant un premier et deuxième passage (7, 9) d'apport délivrant le plastique à partir de multiples sources à un moule (5) de tuyau dans lequel le tuyau est formé avec des parois extérieure et intérieure. Cette filière comprend un séparateur (17) de plastique qui sépare le plastique avant les passages (13, 15) d'apport de façon à déterminer quelle fourniture particulière de plastique va dans quel passage d'apport particulier.
