The overlapped portions of the wrapping material subsequently are joined together. The shrinkable wrapping material is heated to be shrunk to provide an intermediate wrapping member having sleeve openings having a diameter smaller than an inner diameter of the annular article. Sleeve forming portions of the intermediate wrapping member together in a ring-shape along an inner periphery of the annular article.
