  • Method and apparatus for preparing tire tread for a retread tire
    Patent number: 6899778
    Abstract: An apparatus for retreading tires is disclosed. The apparatus has a rotatable hub for the mounting of a buffed tire casing. The apparatus also has a cushion gum applicator that is configured to stretch a length of cushion gum onto a tire casing. Further, the apparatus has a tread dispenser that is configured to automatically dispense a length of tire tread based on the circumference of at least one of the tire casing and the tire casing plus the cushion gum. Further still, the apparatus includes a tread applicator that is configured to stretch the length of tire tread onto the cushion gum. The entire apparatus including the cushion gum applicator, the tread dispenser, and the tread applicator are integrated into a single tire bench machine.

  • Electronic shearography apparatus for producing animation of shearogram images
    Patent number: 6433874
    Abstract: The invention relates to an apparatus for performing electronic shearography on a test object, especially a tire or retread tire. The apparatus uses a laser light source to illuminate the test object. An optical element through which electromagnetic radiation is reflected from the test object is transmitted and forms a random interference image. The random interference image is electronically processed to provide a video animation of the effects of stress on the test object.
