A method for producing a toothed belt (10) having a belt section (13) and a tooth section (14) projecting from the belt section (13), which comprises a first step of applying an aqueous treating agent containing a latex of a first rubber and a first vulcanizing agent on a fiber sheet, followed by drying, to thereby form a reinforcing sheet (12) having a fiber sheet and a coating film formed on the fiber sheet, and a second step of vulcanizing the first rubber and a second rubber at the same time in the state in which the reinforcing sheet (12) and a rubber composition being the material of the tooth section (14) and containing the second rubber and a second vulcanizing agent are closely contacted with each other, to thereby reinforce the surface of the tooth section (14) with the reinforcing sheet (12). The above aqueous treating agent comprises the vulcanizing agent in the range of 10 to 100 parts by mass relative to 100 parts by mass of the first rubber.
L~invention concerne un procédé de production d~une courroie crantée (10) présentant une partie formant courroie (13) et une partie formant dents (14) faisant saillie de la partie formant courroie (13). Le procédé de l~invention comprend une première étape consistant à appliquer un agent de traitement aqueux contenant un latex d~un premier caoutchouc et un premier agent vulcanisant sur une feuille en fibres, puis à sécher de manière à former une feuille de renfort (12) comportant une feuille en fibres sur laquelle est formé un film de revêtement. Dans une deuxième étape, on vulcanise simultanément le premier caoutchouc et un second caoutchouc, la feuille de renfort (12) et une composition de caoutchouc constituant le matériau de la partie formant dents (14) et contenant le second caoutchouc et un second agent vulcanisant étant en contact étroit, de manière à renforcer la surface de la partie formant dents (14) au moyen de la feuille de renfort (12). La quantité d~agent vulcanisant dans ledit agent de traitement aqueux va de 10 à 100 parties en masse, rapportée à 100 parties en masse du premier caoutchouc.
