PROBLEM TO BE SOLVED: To perform excellent work by which cutting, separation and meandering of base materials, a variation in tension or the like are not caused by sandwiching a thermoplastic polyimide film between the base materials to be connected by the base materials to be worked by applying tensile force of a specific range in a specific temperature range, and connecting them to each other by thermocompression bonding. SOLUTION: In base materials to be continuously worked in 0.1 to 50kgf/m of tensile force applied to the base materials in a temperature range of 200 deg.C to 550 deg.C, before passing through a heat press machine 1, the final part of a preceding base material 4 and the forefront part of a work, expected base material 6 sandwich a thermoplastic polyimide film 5, and are superposed on each other, and are temporarily connected to each other by a pressure sensitive adhesive tape 7. When a temporarily connecting part reaches the heat press machine 1, a part of the base material 4 at working time is fixed by a base material fixing device 2, and the temporarily connecting part rests in the heat press machine 1. The heat press machine 1 is actuated, and the base materials 4 and 6 having the thermoplastic polyimide film 5 between them is subjected to thermocompression bonding. Next, the connecting part moves toward an accumulator 3. |
