<p>PURPOSE:To carry out the heat-treatment in the preliminary pressing of a pair of glass plates interposed with an interlayer, continuously, in high efficiency, by using far infrared rays having specific wavelength. CONSTITUTION:An interlayer composed mainly of an ethylene-vinyl acetate copolymer is interposed between a pair of glass plates. Air bubbles existing between the glass plate and the interlayer are expelled, and the glass plates and the interlayer are integrated with each other to complete the preliminary pressing process. The above process is carried out under irradiation with far infrared rays having a main wavelength range of 2-50mu. The preliminarily integrated glass plates are pressed under high temperature and pressure to complete the bonding and obtain the objective laminated glass.</p> |
