发明名称 Method for making knotless bead bundle, a bead bundle made thereby and a tire incorporating said bead bundle.
摘要 <p>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 DEG 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 demonstrates improved uniformity, stability and durability. &lt;IMAGE&gt;</p>
