Abstract

Installation (1) d'extrusion pour fabriquer une bande de profilé, telle une bande de roulement, à base de mélanges élastomériques par coextrusion, comportant plusieurs extrudeuses (10, 20, 30, 40) d'alimentation en mélanges élastomériques d'une tête d'extrusion (2), les extrudeuses étant supportées par deux sous-ensembles (I, II) agencés de part et d'autre de la tête d'extrusion (2). Selon l'invention, chaque extrudeuse communique directement avec un conduit d'entrée (15, 25, 35, 45) de la tête d'extrusion et chaque sous-ensemble (I, II) est monté mobile en translation en étant mû par un dispositif d'entraînement (70) entre une position de fermeture dans laquelle les sous-ensembles (I, II) sont au contact de la tête d'extrusion (2) et une position d'ouverture dans laquelle les sous-ensembles (I, II) sont écartés de celle-ci.
