A continuous article such as steel pipe is covered with a heat-shrinkable covering sheet comprised of a heat-shrinkable plastic layer and a heat-bonding adhesive layer by a process wherein the covering sheet is wound around the periphery of the continuous article, both ends of the covering sheet are lapped together, a heat-sealing tape is further lapped on the lapping portion of the covering sheet to form a tube of the covering sheet, and then the tube is heated to thereby shrink toward the periphery of the continuous article. The heat-sealing tape is characterized by having a heat-bonding adhesive layer formed on one surface of a plastic layer heat-shrinkable in the width direction of the tape. This heat-sealing tape is lapped on the lapping portion of the covering sheet so that the heat-shrinking direction of the heat-shrinkable tape is the same as the heat-shrinking direction of the covering sheet. |
