BONDING OF VULCANIZED RUBBER SHEET

摘要

PROBLEM TO BE SOLVED: To obtain a bonded part high in bonding strength when vulcanized rubber sheets are mutually bonded on the execution spot such as a waste disposal plant or the like, to facilitate the formation of an inspection channel and to perform bonding work due to the fusion of a bonding tape at a time. SOLUTION: A bonding tape 2 comprising an olefinic resin is held between the edge parts of two vulcanized rubber sheets 1A, 1B and heaters 22 for heating the opposed surfaces of the upper vulcanized rubber sheet 1A and the bonding tape 2 and the opposed surfaces of the bonting tape 2 and the lower vulcanized rubber sheet 1B are inserted in the gap of the upper vulcanized rubber sheet 1A and the bonding tape 2 and the gap between the bonding tape 2 and the lower vulcanized rubber sheet 1B and both opposed surfaces are heated while the upper and lower heaters 22 are allowed to run in one direction along the edge parts of the vulcanized rubber sheets and three of the upper vulcanized rubber sheet 1A, the bonding tape 2 and the lower vulcanized rubber sheet 1B are pressed on the behind side in the heater running direction.
