<p>PURPOSE:To make it possible to equip the device with a cooling device without realizing a large-sized laminating device and at the same time prevent a processed item from jamming by a structure wherein heating devices are provided on an inlet side roller side and, on the other hand, hollows, through which cooling fluid is passed, are provided on outlet rollers. CONSTITUTION:By turning a switch on, heating devices 6a and 6b are energized so as to heat the surfaces of inlet side rollers 1a and 1b and endless belts 3a and 3b, which respectively wind round the rollers 1a and 1b. And, at the same time, the switch of a pump 26 is turned on so as to circulate liquid between outlet side rollers 2a and 2b and a radiator 25. Said liquid is cooled with the radiator 25 and carried with the pump 26 through conduits 25 to the hollow shaft parts 22 at the ends of the outlet side rollers 2a and 2b. The liquid is passed through the hollows 20 within the outlet side rollers 2a and 2b and discharged from the hollow shaft parts 22 at the other ends of the outlet side rollers and finally sent back through the pump 26 to the radiator 25. When said low temperature liquid is passed through the hollows 20 within the outlet side rollers 2a and 2b, said liquid carries away the heat of the rollers 2a and 2b, keeping the temperatures at the surfaces of the rollers low.</p> |
