Abstract
Abstract This apparatus includes a horizontal conveyor (3, 4) that has separate supporting elements (9; 11, 12) to support the two panes of glass (31, 32), some of which define a plane of movement of the panes (10), whereas the others define a plane that is parallel to this, and which can be moved out of engagement with the pane of glass (31) that is arranged at a distance from the plane of movement of the panes (10), this being done either synchronously or in groups. In order to inject a paste-like material between the two panes of glass (31, 32) there is at least one nozzle (36) which can be moved parallel to the plane of movement of the panes (10) transversely to the direction of movement (x) of the horizontal conveyor (3, 4). A separator that precedes the nozzle orifices of the nozzle (36) at a constant distance is provided, this penetrating into the space between the two panes of glass (31, 32).
