Latest Patents

One of Tsukada's latest patents is for an annular article-wrapping member and method of making the same. This invention involves a shrinkable wrapping material that is wound around the outer periphery of an annular article. The direction of shrinkage of the wrapping material coincides with the circumferential direction of the article. The overlapping portions of the wrapping material are joined together, and the material is heated to shrink it, creating an intermediate wrapping member. This member features sleeve openings with a diameter smaller than the inner diameter of the annular article. The sleeve-forming portions are arranged in a ring shape along the inner periphery of the article. Finally, the portion of the shrinkable wrapping material that is disposed inwardly of the joined portion is removed by cutting, resulting in the final annular article-wrapping member.
