  • Patent number: 11446853
    Abstract: A method of manufacturing a tire tread includes extruding a rubber strip and conveying the rubber strip through an opening of a roller die. The opening is defined by an upper die and a lower die, wherein the upper die and lower die contact the rubber strip and define a cross-section of the rubber strip as the rubber strip is conveyed through the opening. The method also includes adjusting a distance between the upper die and the lower die as the rubber strip is conveyed through the opening. The method further includes applying the rubber strip from the roller die onto a receptacle that rotates about a receptacle axis. The method also includes translating the roller die in a first direction parallel to the receptacle axis while applying the rubber strip, thereby forming a spiral of the rubber strip about the receptacle.

  • Patent number: 10960626
    Abstract: A bidirectional stitching wheel may be able to conform to peaks and valleys of green rubber while building a tire. The bidirectional stitching wheel may include an inner ring including a stitcher rotation axis. The inner ring may be rotatable in a first stitcher rotational direction about the stitcher rotation axis. The inner ring may also be rotatable in a second stitcher rotational direction about the stitcher rotation axis. A flexible outer ring may be radially spaced from the inner ring. A flexible intermediate layer may be disposed between the inner ring and the outer ring. The flexible intermediate layer may be substantially equally deformable during rotation of the inner ring in both the first stitcher rotational direction and the second stitcher rotational direction.

  • Publication number: 20210001668
    Abstract: A non-pneumatic tire includes a plurality of axially adjacent wheel portions. Each wheel portion has an inner ring, an outer ring, and a flexible, interconnected web extending between the inner ring and the outer ring. The flexible, interconnected web includes a plurality of web sectors disposed circumferentially about the tire to form a generally annular web. Each of the plurality of web sectors is hingedly connected to a pair of oppositely adjacent web sectors.
