A process for firmly bonding a thermoplastic covering sheet on a hard article, for example, a steel pipe or cable, comprising wrapping a heat-shrinkable covering sheet having an adhesive layer around a portion of the peripheral surface of a hard article to be protected and heating the covering sheet so as to shrink it, which process is characterized by placing a pressing band on the covering sheet and by creating a pressure in the pressing band, so as to press the covering sheet against the hard article, thereby removing air bubbles formed between the covering sheet and the hard article. |
