Abstract
Procédé permettant de fabriquer, simultanément, à partir d'une source unique de matière plastique de base, un produit ou plusieurs produits renfermant différentes formes de matière plastique, et appareillage pour mettre en oeuvre ce procédé. Selon ce procédé, on alimente une extrudeuse en une matière plastique de base, on sépare du courant de matière plastique homogénéisée sortant de l'extrudeuse plusieurs courants séparés, on injecte une quantité prédéterminée d'un additif liquide renfermant un modificateur de matière plastique dans au moins un courant de matière plastique de base, on règle le débit d'au moins le courant de matière plastique dans lequel on a injecté l'agent modificateur, on disperse l'agent ou les agents modificateurs dans leurs courants respectifs de matière plastique de base et on amène les différents courants de matière plastique aux moyens de formage des produits extrudés.
