Abstract

Hilera de extrusión, para elementos tubulares huecos de material plástico, caracterizada porque comprende un macho y una matriz asociables a un cabezal de extrusión y que definen en su zona de unión un canal de desarrollo cerrado en comunicación con un conducto de aducción del material plástico a extruir, estando prevista en dicho canal una pluralidad de apéndices conformados, unidos a dicho macho, adyacentes lateralmente entre si y dispuestos a lo largo de todo el desarrollo de dicho canal, definiendo dichos apéndices, en cooperación con dicha matriz, una pluralidad de bocas de extrusión, estando previsto en el interior de dicho macho un conducto de desarrollo cerrado en comunicación con un conducto que desemboca a la atmósfera y con una pluralidad de canalículos cada uno de los cuales se desarrolla en uno de dichos apéndices y desemboca en una de dichas bocas de extrusión.
