Abstract

La présente invention concerne un procédé de rechapage d'enveloppes de bandages pneumatiques en utilisant de l'eau chaude pour vulcaniser une bande de roulement sur un pneumatique préparé. Selon l'invention, on enferme un pneumatique 10 couvert d'une bande de roulement dans une enveloppe flexible et étanche à l'air 12, on place les pneumatiques dans un récipient scellé 28, on introduit une faible quantité d'eau dans le récipient pour y augmenter suffisamment la pression d'air pour forcer ce dernier à sortir des enveloppes 12 par des évents 22 conduisant de l'intérieur de l'enveloppe vers l'atmosphère, pour presser l'enveloppe contre la bande de roulement, après expulsion de l'air en dehors de l'enveloppe 12, on introduit plus d'eau dans le récipient pour couvrir le pneumatique dans l'eau à une température et une pression prédéterminées, on maintient l'eau dans le récipient pendant un temps prédéterminé jusqu'à vulcanisation, et on enlève l'eau du récipient et le pneumatique de l'enveloppe. L'invention s'applique notamment aux pneumatiques pour automobiles ou camions.
