Title:
ダブルVリブドベルトの製造方法及び成形プレス装置
Document Type and Number:
Japanese Patent JP4907785
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a manufacturing technique of a double V-ribbed belt for solving a problems such as work dispersion, in a manufacturing process using EPDM materials having less adhesiveness, especially in a conventional process of laminating the EPDM materials by sequentially winding rib part rubber or the like on the outer surface of a cylindrical die and joining both ends. SOLUTION: In a first molding process, a lower rib part rubber 3 adhered to the surface of a die cylinder is previously formed cylindrically and engaged. A third molding process employs a first method of winding upper rib part rubber 6 on a core wire 4 winding surface and previously thermally crimping a joint part to make its ends endless and a second method of previously forming the upper rib part rubber 6 cylindrically and fitting the rubber over the core wire 4 winding outer surface.
