PROCEDE DE SOUDAGE PAR HAUTE FREQUENCE DE FEUILLES THERMOSOUDABLES DONT AU MOINS UNE EST EN POLYCARBONATE

摘要

The invention relates to a method for welding thermoweldable sheets of which at least one is made of polycarbonate. The method is characterized in that the sheets to be welded are separated from the metal electrodes (4, 5) of the high frequency press by means of a glass plate (2, 3). Application to the fabrication of high density magnetic cards.
