<p><P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a synthetic resin bubble sheet laminate with improved productivity of the synthetic-resin bubble sheet laminate without limiting a dimension of a completed product. <P>SOLUTION: At least an uneven sheet 11 and a flat sheet 12 are joined to each other, and are fed downstream of the sheet flow in a state of laminating synthetic-resin bubble sheets 10 formed with a large number of bubble parts 13 sealing gas therein. The laminated synthetic-resin bubble sheets 10 are pressurized from outside to make facing surfaces contact each other, the synthetic-resin bubble sheets 10 in a pressurized state are heated to the melting temperature of the synthetic resin or higher, and the facing surfaces of the laminated synthetic-resin bubble sheets 10 are fused to each other. In a heating process, high-temperature air at the melting temperature of the synthetic resin or higher is supplied to the synthetic-resin bubble sheets 10 in the pressurized state. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
