ABSTRACT:
A reinforced, mechanical splice for toothed belts, the splice defined by overlapping belt end portions that interfit with each other with a male-end belt tongue portion having transversely oriented belt teeth with molded end receiving openings, and a female-end belt U-portion dimensioned to receive the male-end portion and having transversely aligned belt teeth with molded pin receiving openings so adapted and arranged for coaxial alignment with the male-end pin receiving openings such that the belt teeth of the male-end portion are aligned with the belt teeth of the female-end portion, the belt teeth of both end portions having an embedded reinforcement circumjacent to the pin receiving openings. The belt splice is formed by positioning a twined reinforcement around a polymeric rod, placing the rod with reinforcement in a mold such as successive tooth cavities, placing a circumferentially oriented tensile member next to the rod and reinforcement, embedding the rod, reinforcement, and tensile member in an elastomeric matrix forming a toothed belt, and cutting through the belt at the tensile member, rod and reinforcement and forming a male-end belt tongue portion and a female-end belt U-portion.
