  • Bead jamming or crimping method
    Patent number: 4496411
    Abstract: A method for crimping tire bead rings in which an inner die member has grooves for holding the bead rings in the area of the bead splices and an upper die member engages the outer surface of the bead rings in that area. The die members are compressed with sufficient force for a sufficient period of time so that the strands of the bead rings are held together by the insulating material around the strands in the area of the bead splices. The side portions of the grooves control the spreading of the bead rings and may be flared to compress and then release the bead rings. The grooves of the inner die member may have movable inserts for ejecting the bead rings. The upper die member may also include grooves in mating engagement with the grooves of the inner die member for enclosing the outer portions of the bead rings at the splice area and provide for release of the bead rings after crimping.
    Type: Grant
