    • A method of manufacturing of the present invention is a method of manufacturing a toothed belt (10) having a belt part (13) and a tooth part (14) sticking out of the belt part (13). This method of manufacturing includes a first step of forming a reinforcing-sheet (12) including a fiber sheet and a coating film formed on the fiber sheet by drying the fiber sheet on which an aqueous treatment agent containing a first rubber latex and a first vulcanizing agent is applied, and a second step of reinforcing a surface of the tooth part (14) with the reinforcing-sheet (12) by vulcanizing the first rubber and a second rubber at the same time while adhering a rubber composition, which is a material for the tooth part (14), including the second rubber and a second vulcanizing agent to the reinforcing-sheet (12). The aqueous treatment agent contains the vulcanizing agent in the range of 10 parts by weight to 100 parts by weight for 100 parts by weight of the first rubber.
    • 本发明的制造方法是制造具有带部(13)的齿形带(10)和从带部(13)伸出的齿部(14)的方法。 这种制造方法包括:第一步骤,通过干燥含有第一橡胶胶乳的水性处理剂和第一硫化纤维的纤维片,形成包含纤维片和涂膜的增强片(12) 以及第二步骤,通过在粘附作为材料的橡胶组合物的同时硫化第一橡胶和第二橡胶的同时用增强片(12)来增强齿部(14)的表面 对于包括第二橡胶和第二硫化剂的齿部分(14)到加固板(12)。 对于100重量份的第一橡胶,含水处理剂含有10重量份至100重量份的硫化剂。
