A re-treading method and an apparatus therefor, which are capable of winding a tread material on a base tire automatically and efficiently to realize an adequate joint condition of the leading and trailing edges of the tread material, are configured to take a photograph of a zone of the tread material including its cut position to compare the picture with a stored tread pattern image to detect a deviation amount between them, then moves the tread material or the cut position relative to each other by the deviation amount, next cut the tread material at the cut position after the relative movement, wind the tread material on a base tire, and unite the leading and trailing edges of the tread material. Alternatively, the re-treading method and the apparatus can detect a deviation amount of the position distant by a required tread length from the leading edge of the tread material from a predetermined pattern position near that position planned to be cut, cut the tread material at the at the predetermined position, wind the cut-out tread material on the outer circumference of the base tire while adjusting the length of the tread material by applying thereto a substantially uniform tensile or compressive force, and unite the leading and trailing edges of the tread material wound on the base tire.
