PROBLEM TO BE SOLVED: To provide a method for manufacturing a V-ribbed belt and the V- ribbed belt with such advantages as high wear resistance and cold resistance without having to apply surface treatment such as grinding and polishing. SOLUTION: An unvulcanized belt sleeve 11 in which a canvas 15 with a rubber, an unvulcanized adhesive rubber sheet 12, a tensile body rope 13 and an unvulcanized compression rubber sheet 20 provided with a metal and/or a ceramic reinforcing layer 16 are successively and endlessly wound on the cylindrical drum 21, is disposed to an inner cylindrical drum 21 equipped with a flexible jacket 22. Air is injected in the flexible jacket 22 to uniformly expand the jacket 22 in the radial direction, so as to closely adhere the unvulcanized belt sleeve 11 to an outer mold 26 engraved with a V shaped groove to vulcanize. The vulcanized belt sleeve thus obtained is cut to a desired width to provide a V-ribbed belt having a reinforcing layer on a compression rubber surface. COPYRIGHT: (C)2004,JPO |
