Abstract

L'invention concerne la transformation d'une matière de résine synthétique thermoplastique en un article ayant les propriétés de travail et de mise en oeuvre du bois. Cette matière est soumise à une opération de mélangeage dans un fourreau d'extrudeuse à vis, est rendue fluide, est moulée, est refroidie dans le moule et est extraite du moule Le procédé se caractérise par l'introduction de la matière dans une extrudeuse à vis 3 sans grille-écran et sans filière d'extrusion, dans laquelle la matière est maintenue jusqu'à l'obtention d'une matière fluide sous l'action de l'élévation de la température et qu'elle quitte en contenant un gaz pour alimenter un moule 8 ouvert à ses deux extrémités, dont l'une est raccordée à la sortie de l'extrudeuse. L'invention est applicable au traitement de déchets de matière synthétique thermoplastique.
