  • Patent number: 4778504
    Abstract: Method for bonding the edges of all-glass multiple panes, particularly all-glass double panes, whereby the individual panes moving through an elongated tunnel furnace or the like are cut to size, may potentially be washed, are subjected to an at least partial edge smoothing, are aligned with one another and, after being pre-heated to a pre-heating temperature lying below the deformation temperature of the glass, are bonded to one another at the horizontal and vertical pane edges, being bonded while standing upright, characterized in that individual panes cut to size and potentially washed are individually pre-heated lying on their surface facing away from the pane interspace of the all-glass multiple pane to be manufactured, and in that the individual panes are subsequently placed upright and are placed together to form groups of individual panes in accord with an all-glass multiple pane to be manufactured, whereupon the edge bonding ensues; further, apparatus for the implementation thereof.

  • Patent number: 4259135
    Abstract: A technique for factory glazing of glass panes in window frames is provided. Each frame has a pane receiving groove which corresponds in its depth approximately to the thickness of the glass pane. This groove is filled with a pane edge and a hardenable sealing mass. The invention further relates to a process for factory glazing of glass panes, in particular, glass panes which have been individually inserted into a window frame groove that is open or accessible on one side and that corresponds in its depth approximately to the thickness of the glass pane. When such groove is filled with a hardenable sealing mass, the latter is subsequently hardened.
