ABSTRACT:
A re-treading method and an apparatus. An image of a zone of the tread material including its cut position is compared with a stored tread pattern image to detect a deviation amount. The tread material or the cut position are moved relative to each other by the deviation amount. The tread material is cut at the cut position after the relative movement. The tread material is wound on a base tire, and the leading and trailing edges of the tread material are united. The tread material or cut position may not be moved relative to each other if the deviation amount is within an allowable range.
