    Abstract: A method for making a knotless bead bundle, a bead bundle made according to the method, and a tire made using the knotless bead bundle are provided. In the method a bead ring is made using a plurality of annular turns of wire as is conventional in the art, and the annular turns of wire are wrapped with cord, tape, or other conventional wrapping material which is held on the bead ring without using knots. The wrap is held on the bead ring by using a tie down area that is made by forming a loop in the wrapping material, holding the loop in place by a number of close turns of wrap on the bead ring while leaving a first end of the wrapping material free, wrapping the bead ring 360.degree. around the ring, passing a second end of the wrapping material through the loop, closing the loop by pulling the first end of the wrapping material whereby closing the loop pulls the second end of the wrapping material under the close turns of wrapping material. The ends of the wrap are then cut flush with the close turns of wrap. A tire made using the bead bundle of the invention durability. demonstrates improved uniformity, stability and

    Abstract: A method and apparatus for manufacturing a strip of ply or belt stock reinforced with steel monofilaments fed from a plurality of reels (60, 60', 60") mounted on the spindles (54) of a reel support structure (18). The article of manufacture which results from the method is a uniform strip of reinforced ply or belt stock of higher epi, smaller gauge and fewer splices than possible with prior method and apparatus.

    Abstract: A method and apparatus for manufacturing a strip of ply or belt stock reinforced with steel monofilaments fed from a plurality of reels (60,60', 60") mounted on the spindles (54) of a reel support structure (18). The article of manufacture which results from the method is a uniform strip of reinforced ply or belt stock of higher epi, smaller gauge and fewer splices than possible with prior method and apparatus. A plurality of the reels for feeding the monofilaments are mounted on a spindle secured at one end, with friction means (64,66) disposed between each of the reels located adjacent to each other for applying an axial braking force to each of the reels. A spring biasing means (68) is disposed between each of the reels located adjacent to each other for pressing the friction means (64,66) against the adjacent reels.

    Abstract: The present invention relates to a radial pneumatic tire having a contoured zone located in each of the sidewalls of the tire. The contoured zone improves the sidewalls ply durability and decreases upper sidewall circumferential ply-wire breakage, also known as zipper-break. More particularly, the radial pneumatic tire comprises (1) at least one circumferential reinforcing belt; (2) a pair of sidewalls extending from opposing edges of said reinforcing belt to corresponding tire beads and containing a single reinforcing cord ply that wraps around each bead and having two terminal ends; (3) an inner cavity; (4) a contoured zone, wherein said contoured zone is (a) located between said single reinforcing cord ply and said inner cavity, (b) is circumferentially extending about the axis of the tire, (c) located in a region of each sidewall defined by the area from said reinforcing belt to the terminal ends of said single reinforcing cord ply, and (d) wherein the distance between the single reinforcing cord ply and said inner cavity is greater in the region where the contoured zone is located in comparison to the distance between the single reinforcing cord ply and said inner cavity in the region beneath said reinforcing belt.
