<p>Separation of glass and foils, especially of laminated glass panes, involves breaking the panes (8) in a breaker device (3), heating the broken panes in a hot bath (7) and separating the residual glass (8.1) from the foils (8.2) by means of a detaching device (9). Preferably, the breaker device (3) is an encapsulated energy transducer, especially for directly coupling high power pulses (15) to the panes (8), or a roller mill and the detaching device (9) employs a high pressure water jet or a scraper. Preferably, the high power pulses (15) comprise 10-40 pulses with an energy of 2-8 kJ per pulse. The hot bath (7) is preferably at 40-70 degrees C. The panes (8) are preferably transported to the individual stations by a screen-like conveyor (2, 6) having, at its side edges, gripper systems for holding the panes (8). An installation for separating laminated panes (8) into glass (8.1) and PVC foils (8.2) has perforated conveyors (2, 6) for transporting the panes to a breaker device (3) which breaks the glass into less than 50 mm<2> pieces; a hot water bath (7) at 40-70 degrees C for heating the panes for 10-30 mins. to reduce adhesion of the glass to the foils; and a high pressure (up to 6 bars) water jet or scraper device (9) for detaching the remaining glass from the foils.</p> |
