METHOD OF PREHEATING LAMINATE, AND METHOD AND APPARATUS FOR PRODUCING THE SAME

摘要

A method of preheating a polymer plate by induction-heating by applying a radio frequency voltage to a laminate in the direction of its lamination through electrodes; a method of producing a laminate, comprising inductionheating a polymer plate by applying a radio frequency voltage to a laminate in the direction of its lamination through electrodes in a state where the laminate is housed in an annular container encompassing the surfaces of the laminates, and pressing the laminate in the direction of its lamination at least after completion of the application of the radio frequency voltage; and an apparatus for producing the laminate.
