PROCEDE DE FABRICATION D'UN PNEUMATIQUE, ET APPAREILS POUR LA MISE EN ÓOEUVRE DE CE PROCEDE

Les renforts pour pneumatiques sont réalisés à partir d'un seul fil dont on avance un tronçon 40 par dessus un noyau rigide 2, jusqu'à ce que au moins la partie centrale soit en regard de sa position finale sur le support, puis des rabatteurs 5 plaquent successivement chaque tronçon 40 radialement sur le noyau 2 grâce à des taquets 50 agissant sur le tronçon 40 à la manière d'un doigt. A tyre is progressively constructed by the build up of the constituent parts on a support. The reinforcement, as a single wire of the appropriate material, textile or metal, is fed over the support. One fixed length section of the wire is placed over the support, perpendicular to a radius and at the required angle. It is radially flattened against the support by the action of two forming means each side of the support. The forming means have a cyclic movement from the top level of the support descending and approaching the support in the direction of its axes of rotation, during which the section of wire is gripped; by stops mounted on a belt passing over two pulleys; and flattened against the support.
