Abstract

Appareil de démontage et de remontage d'un anneau destiné au moulage des bandes de roulement de pneumatiques. Il comprend des dispositifs à mâchoires dont le nombre correspond au nombre de segments constituant un anneau destiné à la réalisation de la bande de roulement des pneumatiques moulés par centrifugation. Les dispositifs à mâchoires sont commandés par des vérins et leurs mouvements sont guidés de manière qu'ils éloignent l'anneau d'un pneumatique venant d'être moulé, puis qu'ils remontent l'anneau après que le pneumatique a été retiré. Domaine d'application : fabrication de pneumatiques de véhicules.
