摘要： The invention relates to a method comprising:
providing a plurality of cords (106)
dipping the plurality of cords a first tank comprising a polyurethane emulsion stabilized with internal anionic and external nonionic species, dipping the plurality of cords a second tank comprising RFL suspension, and dipping the plurality of cords a third tank comprising rubber based polymer, to provide a plurality of treated cords;
providing a first elastomeric layer;
laying up the plurality of treated cords (106) on the first elastomeric layer to form tensile reinforcement layer;
laying up a second elastomeric layer on the tensile reinforcement layer; and,
curing the combination of the first elastomeric layer, the tensile reinforcement layer and the second elastomeric layer in a profile fomring mold.
Methods of manufacturing a belt are also disclosed.摘要翻译： 本发明涉及一种方法，其包括：提供多根帘线（106），所述多根帘线浸渍包含用内部阴离子和外部非离子物质稳定的聚氨酯乳液的第一罐，将所述多根帘线浸入包含RFL悬浮液的第二罐中，以及 将多根帘线浸入包含橡胶基聚合物的第三罐中，以提供多根处理过的帘线; 提供第一弹性体层; 在第一弹性体层上铺设多根处理过的帘线（106）以形成拉伸增强层; 在拉伸增强层上铺设第二弹性体层; 以及在型材成型模具中固化第一弹性体层，拉伸增强层和第二弹性体层的组合。 还公开了制造带的方法。

摘要： A synchronous drive belt includes (100) an outer tension section (102) and opposing continuous tooth section (104) defining an outer surface. The synchronous drive belt further includes a cross-linked elastomeric body (106), and a tensile reinforcement section (108) disposed between the outer tension section (102) and the cross-linked elastomeric body (106). A fabric reinforcement (110) is disposed inwardly adjacent the outer surface of the continuous tooth section (104), and the fabric reinforcement (110) is enveloped by the cross-linked elastomeric body (106). Further, the cross-linked elastomeric body (106) forms the outer surface of the continuous tooth section (104). In some aspects, the cross-linked elastomeric body (106) contains a urethane material, which may be formed from the reaction product of a polyisocyanate and a hydroxyl functional polyol during a belt molding process. The polyisocyanate and the hydroxyl functional polyol may envelop the fabric reinforcement (110) prior to reacting during the belt molding process, or even while reacting in the molding process.
