Abstract
The cleaner includes an elevator for moving a tire vertically toward a stationary cleaning head which is made up of spreader rollers for spreading the tire beads a sufficient distance to admit a powered cleaning brush, along with cleaning fluid application and removal apparatus, into the tire interior during such tire movement. The elevator further supports and rotates the tire with respect to the brush during cleaning while the spreader rollers, together with additional fixed guide rollers, maintain the tire vertical and in alignment with the brush. The elevator lifts each tire from a horizontal conveyor which alternately discharges a cleaned tire and receives a fresh one. During cleaning, the brush is movable transversely along an arcuate path within the tire interior at selected contact pressure and is driven alternately in opposite directions. The cleaner is suited for usage in a system for producing self-healing tires.
