PROBLEM TO BE SOLVED: To form a bonding section of strong bonding force at the time of bonding vulcanized rubber sheets each other on a working site of a waste disposal section or the like, form an inspection channel easily and generate no shifts between upper and lower vulcanized rubber sheets on the bonding section. SOLUTION: In a method for arranging edges of both of two vulcanized rubber sheets 1A and 1B in a manner of being overlapped up and down and bonding them together, a bonding tape 2 composed of olefin resin is heat fusion bonded preliminarily on the edge of one vulcanized sheet 1A, and while the edge of the other vulcanized rubber sheet 1B is overlapped on the bonding tape 2, an opposite face just before being overlapped is heated, and then ends of two vulcanized rubber sheets, upper and lower, are clamped between a pair of contact bonding rollers 12 and 18, upper and lower, rotating facing each other at the equal speed, and both sheets are bonded together by the fusion bonding of said bonding tape 2. |
