ABSTRACT:
The tire spreading and inspecting machine of the present invention includes a frame for supporting a tire in an inspection position. Drive rollers are provided on the frame for rotating the tire about its axis and specially designed spread arms are arranged for engaging the beads of the tire and spreading them apart to permit inspection of the tire carcass. An offset in the spreading arms prevents the rollers from jumping out of the tire as the tire is rotated. Sidewall support rollers are also provided on the frame for contacting the sidewalls of the rotating tire to prevent the tire from collapsing before sufficient spread is achieved. This feature is particularly important when the machine is used for inspecting radial tires whose characteristics make inspection on conventional equipment impractical. Finally, a tire lift attached to the frame includes a lock and roller for applying pressure to the tire to prevent it from coming off the rollers during rotation.
