Abstract
PURPOSE:To prevent bubbles from remaining between a sheet and a connecting part by a method wherein a thermally shrinkable sheet is put around the outer circumferential surface of a connecting part between long sized material, grounded, a pressure sheet is put on the outer circumference of said sheet and bonded as the inside is kept in a pressed state. CONSTITUTION:A thermally shrinkable sheet 49 is wound about the outer circumference of a long sized material connecting part 30, heated by a gas burner etc., grounded to the surface of the connecting part 30 and then a pressure sheet 51 is wound about the outer circumference of said sheet 49 and enclosing auxiliaries 63a, 63b on both side edge parts of the sheet 51 are attached closely to the surface of both side edge parts of the sheet 49 to form an enclosed system. Gas is introduced into this enclosed system through a gas introducing pipe 54 under the pressure, the enclosed system is pressed to 1.05-1.5 atm., the bubbles remaining between the sheet 49 and the connecting part 30 are pushed out and bonded.
