  • Patent number: 4608219
    Abstract: A tire press, loader and method employs a stationary bottom mold section and a vertically movable top mold section which moves upwardly to open the press clearing the area therebetween for discharge of the cured tire and loading of the green or uncured tire. The press loads the green tire initially into the top mold section centering and holding the top bead of the green tire on the bead ring of the top mold section. To position the uncured tire for such top loading there is provided a loader which engages the uncured tire at the lower shoulder of the tread area. The loader includes pivotally movable chuck sector assemblies, each mounted on a ring. The ring can readily be centered with respect to the axis of the mold sections and each assembly can be moved concurrently uniformly radially of the ring to accommodate tires of different sizes.

  • Patent number: 4580958
    Abstract: A loader for a tire curing press comprising a support, a loader frame mounted to the support for vertical and horizontal movement, a loader basket mounted to the loader frame for engaging, holding and releasing a tire, a first actuator for vertically moving the loader frame, a second actuator for horizontally moving the loader frame into and out of the press when open, and a mechanical guide for guiding the loader frame from an over-center position in the press to a center position as the loader frame is moved vertically in the press. The loader frame is supported on a spline shaft for movement therealong and rotation therewith by ball bushings riding in the grooves of the spline split. The loader basket comprises a plurality of generally radially movable shoes, an adjustable stop for limiting radial movement of each shoe and an adjustment mechanism for simultaneously and uniformly adjusting the adjustable stops.

  • Patent number: 4527946
    Abstract: A pop-up, rotating nozzle in a tire curing press provides for dispersed and uniform introduction of fluid media into the upper containment portion of a curing and shaping bladder during tire cure and cooling, and yet allows for relatively close spacing of upper and lower bladder clamps such as during bladder insertion and stripping operations. The nozzle has an outlet head in communication with the interior of the bladder and a supply stem mounted in a lower bladder clamp and porting assembly of the press for both axial and rotational movement. The nozzle is movable against a spring biasing force by the upper bladder clamp to a lowermost retracted position which allows the bladder clamps to be axially spaced apart a distance substantially less than their axial spacing during cure.
