  • Post cure inflator and vulcanized tire cooling method
    Patent number: 7311872
    Abstract: A post cure inflator for expansion-cooling a vulcanized tire is provided with a vulcanized-tire holding mechanism for holding the vulcanized tire and a rotating mechanism for rotating the vulcanized tire at a high speed via the vulcanized-tire holding mechanism such that a forced convection becomes more dominant than a natural convection in an air flow around the vulcanized tire.
    Type: Grant
    Filed: October 26, 2005
    Date of Patent: December 25, 2007
    Assignees: Kobe Steel, Ltd., Sumitomo Rubber Industries, Ltd.
    Inventors: Hisashi Mitamura, Kazuto Okada, Akio Hakamada, Yutaka Yoshida
  • Raw tire forming apparatus and raw tire forming method
    Patent number: 7208061
    Abstract: It is an object of the present invention to precisely and efficiently paste a tread ring and a raw tire base body with each other. A ring-like base body 5 is aligned with a former 3. The ring-like base body 5 relatively approaches and separates from a former 3. The ring-like base body 5 includes pasting means 6 which pastes a tread ring A to a raw tire base body B. The pasting means 6 includes a grasping tool 11 having a plurality of segments 13 which abut against an outer peripheral surface of the tread ring A to grasp the tread ring A. The pasting means 6 also includes a pushing-down pasting tool 12 having an annular rubber tube body 15. The rubber tube body 15 is disposed on each side of the segment 13 and pushes down a shoulder side portion As of the tread ring A by expansion to paste the shoulder side portion As to the raw tire base body B.
