Then a tension member code is wound in the spiral shape, and the tension of the positioning string 22 is released and removed from the tooth forming recessed channel 3. Then an unvulcanized rubber sheet is wound on the tension member code, and then pressure vulcanization molded to mold a cylindrical slab, and the slab is cut into round slices of a given width to manufacture a boothed belt.;COPYRIGHT: (C)1997,JPO
