Title: Welding the edges of glass panels in mfg. double glazing - with simultaneous correction of any curvature in the panes
Inventor: WORTMANN HANS-JUERGEN
IPC: C03B23/24
Filed: 1975-09-27
Abstract: On each side of the double pane is a pair of guide rods, which can be moved at 90 degrees to the panes and laid on the outside surface of each pane. The uide rods are fitted with suction pads. The novelty is that the top ends of the guide rods are located on pivots above the double pane and inside the furnace, the suction pads are located towards the lower ends of the guide rods, which can be driven towards or away from the panes by work cylinders located outside the furnace. The two panes can thus be moved towards or away from each other. After the horizontal edges of the panes have been welded the panes either bulge outwards or have sunk inwards. The guide rods correct these defects during the welding of the vertical edges, which is the next operation after welding the horizontal edges.
