摘要: This invention relates to a recoverable article for covering objects in which two or more cover pieces are joined together to form the article. The shape and recovery ratios of the cover pieces are chosen such that the amount of recovery does not differ by more than 20% on either side of the join line. This avoids wrinkling.
