Abstract
A top fabric is laminated with an adhesion rubber sheet made of an unvulcanized rubber sheet, which is located on the upper side from a cord of an adhesion rubber layer and forms an upper rubber portion of the adhesion rubber layer, thereby forming a band-shaped laminate. Both longitudinal ends of the band-shaped laminate are butt-jointed with each other so as to produce no level difference at the top surface of the top fabric and at the bottom surface of the adhesion rubber sheet. Thereby, the cord wound around the laminate in the subsequent step is embedded in the adhesion rubber layer without being displaced in level so that the obtained V-ribbed belt produces no abnormal vibration and no noise even if used in serpentine drive.
