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 induction- heating 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.
Cette invention se rapporte à un procédé de préchauffage d'une plaque polymère consistant à chauffer par induction un stratifié en lui appliquant une tension R.F., suivant sa direction de stratification, par l'intermédiaire d'électrodes. L'invention se rapporte également à un procédé de production d'un stratifié, consistant à chauffer par induction une plaque polymère en appliquant une tension R.F. à un stratifié, suivant sa direction de stratification, par l'intermédiaire d'électrodes, ledit stratifié étant logé à l'intérieur d'un contenant annulaire qui entoure ses surfaces, et à comprimer le stratifié suivant sa direction de stratification, après l'application de la tension R.F. L'invention se rapporte également à un appareil de fabrication de stratifié.
