Abstract

L'invention porte sur un procédé qui permet de produire un pneu, en particulier un pneu creux non pneumatique, et sur un mandrin d'extrusion spécifique pour matrice d'extrusion. Selon l'invention, un mélange de caoutchouc est distribué à une extrudeuse et est extrudé afin de former une bande de caoutchouc à plusieurs creux à une température réglée entre 90 et 110 °C. La bande de caoutchouc obtenue est coupée pour former une bande de caoutchouc à deux extrémités. Les deux extrémités sont alors placées dans un appareil d'aboutage et unies entre elles afin de former une bande de caoutchouc annulaire à plusieurs creux. La bande de caoutchouc annulaire obtenue est placée dans un appareil de mise en forme et vulcanisation et vulcanisée, la pression dudit appareil est réglée à un niveau supérieur ou égal à 4-5kgf/cm2 à température ambiante, la température de vulcanisation est réglée dans une plage comprise entre 137 et 145 °C, la pression interne du pneu est réglée dans une plage comprise entre 12 et 26kgf/cm2 et maintenue pendant 8 à 60 minutes, et l'on obtient de cette manière un pneu creux non pneumatique. Le procédé de l'invention permet d'éviter la multiplication et la répétition d'étapes en comparaison avec le procédé de production de pneu externe ou de tube interne d'un pneu pneumatique. Le procédé de l'invention permet de produire un pneu creux non pneumatique en une étape et, par conséquent, d'améliorer l'efficacité de production, d'économiser les sources d'énergie et de réduire l'apport de main d'oeuvre.
