Abstract

a. Procédé et appareil pour former une bande de roulement sur une enveloppe pneumatique. b. L'invention décrit un appareil comportant un organe inférieur sur lequel on place une bande de caoutchouc et un organe supérieur qu'on abaisse sur l'organe inférieur, ce mouvement relatif ayant pour effet de faire avancer vers l'intérieur des patins de profilage qui impriment les sculptures d'une bande de roulement dans le caoutchouc. c. Concerne l'industrie du caoutchouc et plus particulièrement, la fabrication des enveloppes pneumatiques pour véhicules.
