<p>PURPOSE:To improve the running property of running belts over a long period of time to enable continuous manufacture, by a method wherein hot plates for heating a plurality of sheets to be laminated inserted between two running belts running in upper and lower sides under pressure are arranged above and below said belts and piercing holes communicating with the side surface of each running belt are provided to each hot plate to recirculate oil. CONSTITUTION:Hot plates 3a, 3b, which heat a plurality of sheets to be laminated inserted between two running belts 1a, 1b running in upper and lower sides under pressure, are arranged above and below the running belts 1a, 1b and a piercing hole 4 communicating with the side surface of each running belt 1 is provided to each hot plate 3 and an oil recirculating hydraulic pump 5 is connected to said piercing hole 4 to recirculate oil to the piercing hole 4 and an oil film layer 6 is provided to the side surface of the running belt 1 of each hot plate 3. This oil film layer 6 functions as a slip and cushion material and the running property of the running belt 1 can be secured to a good state over a long period of time even under high molding pressure and productivity can be enhanced.</p> |
