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.

Abstract: A solid monolithic tire for use on a wheel rim can be improved by incorporating within the tire a circumferentially extending tunnel formed on the inside of the tire body. Further, the tire body has inclined side walls that converge outwardly to form a V-shaped cross section. The apex of this V-shaped cross section forms the tread portion of the tire. Each of the side walls of the tire terminate in a thickened portion which forms a bead shoulder capable of seating on the bead flanges of the wheel rim to which the tire is mounted. Extending down through the thickened portion of either side of the tire is a bead which has a lower bead wall on the portion most distal to the thickened portion. A bead cord extends circumferentially embedded within the bead near the lower bead wall. The process by which the tire is formed allows the bead cord to be positioned in its appropriate place within the bead.
