Patent ID: 7101455

Claim:
A method of continuously forming a laminate by thermally laminating a plurality of laminating materials including a thermally fusible laminating material and a laminating material comprised of a metal, including the steps of: continuously assembling a plurality of layers of laminating material, including a thermally fusible laminating material and a laminating material comprised of a metal, into a continuous laminate; providing, as at least one of two outermost layers of said plurality of layers of laminating material, a layer of said laminating material comprised of a metal; preheating a protective material to a predetermined temperature and continuously arranging said protective material in contact with said layer of laminating material comprised of a metal; engaging said preheated protective material with the pressing surface of a thermal-press forming device to continuously bond said assembled layers of laminating material together into said laminate and adhere said protective material to said layer of laminating material comprised of a metal by thermal pressure at a temperature of not lower than 200° C., said predetermined preheating temperature being higher than said thermal pressure temperature; cooling the bonded laminating materials with the protective material adhering to said outermost layer whereby said adhered protective layer restrains said laminate from shrinking to the extent shrinking would occur if the bonded laminating material was not restrained in such a manner; and peeling off the protective material form the bonded laminating materials after said laminate has cooled.
