  • Tire ply splice construction and method of making the same
    Patent number: 4466473
    Abstract: A method of making radial pneumatic tires substantially reduces or eliminates sidewall indentations in the inflated tire. A plurality of cuts is made in one end of each layer of ply fabric where the end of the ply fabric overlaps the other end to form a splice which results in the generally annular shape of the ply layer. The cuts extend in a direction generally transverse to the end edge and preferably have a length which is approximately the same as the width of the overlap of the cut edge with the other edge. The cuts prevent overtensioning of the ply cords, which otherwise result in sidewall indentations.
