Abstract:
A method for forming a continuous material by connecting a preceding sheet material with a succeeding other sheet material in end-to-end relationship while feeding them in their longitudinal direction, said method comprising the steps of:(1) interposing a resin bonding layer between the trailing edge of the preceding sheet material and the leading edge of the succeeding other sheet material and temporarily joining them together; (2) after the preceding sheet material and the succeeding other sheet material are fed until the temporarily joined part reaches a hot press, operating a material locking device to lock a part of the preceding sheet material and thereby bring the temporarily joined part to a standstill within the hot press, and also operating an accumulator to keep the teed speed of the preceding sheet material constant on the downstream side thereof; (3) operating the hot press to effect thermocompression bonding of the temporarily joined part and thereby connect the preceding sheet material 4 with the succeeding other sheet material; and (4) releasing the preceding sheet material from the lock by the material locking device and feeding the connected sheet materials downstream through the accumulator.
