ABSTRACT:
An automatic device for perimetric sealing of an insulating glazing unit composed of at least two glass panes and at least one spacer frame supported and movable in a slightly inclined position with respect to the vertical on a conveyor. A sealing head movable with relative motion with respect to the glazing unit has at least one sealing nozzle suitable to deliver a sealant flow. In order to maintain the correct mutual position of said at least one sealing nozzle with respect to the cavities of the glazing unit to be sealed and to allow the spacing of the nozzle therefrom, a sensor is provided transversely to the plane of the insulating glazing unit that detects the distance from the glass pane. An actuation mechanism is further provided for the relative motion between the sealing head and nozzle and the glazing unit.
