Title
(EN) METHOD OF MANUFACTURING TIRE TUBE CONTAINING SEALANT
(FR) PROCEDE DE FABRICATION DE CHAMBRES A AIR CONTENANT UN PRODUIT OBTURANT
Abstract
(EN)
A tube stock (2'), an interior of which is compartmented into an air chamber (3) and a sealant chamber (7) by a partition (5), is subjected to extruding and cut into a predetermined length, and after an air valve (6) communicating to the air chamber (3) is mounted to the tube stock (2'), both ends of the tube stock (2') is joined by pressure welding to be vulcanized. After a sealant filling hole (41) communicating to the sealant chamber (7) is formed in the tube stock (2'), air is supplied to the air chamber (3) through the air valve (6) to push the partition (5) to expel air from the sealant chamber (7), in which state a sealant (8) is supplied into the sealant chamber (7) through the sealant filling hole (41). The sealant filling hole (41) is closed by applying a raw rubber sheet (19) to the tube stock and vulcanizing the same.
(FR)
Un boudin de chambre à air (2'), divisée par un cloisonnement (5) entre la chambre à air (3) proprement dite et un compartiment (7) destinée à être remplie d'un antifuite, est extrudé, découpé en longueurs prédéterminées, puis muni d'une valve (6) avant que ses deux extrémités ne soient réunies par pression, puis vulcanisées. On perce ensuite un trou (41) de remplissage de l'antifuite communiquant avec le compartiment (7), puis on gonfle la chambre à air (3) par la valve (6) pour repousser le cloisonnement (5) et expulser l'air du compartiment (7). On remplit alors le compartiment (7) d'antifuite par le trou (41), qui est ensuite refermé par une feuille (19) de caoutchouc naturel qu'on vulcanise.
