A dosage device for extruding a bicomponent or a monocomponent sealant, particularly for an automatic machine for sealing a perimetric edge of an insulating glazing unit constituted by at least two glass sheets and by at least one spacer frame, having a finite width, is arranged proximate to the perimeter at a finite distance from the margin of the glass sheets, includes a first dosage assembly and a separate second dosage assembly for the dosage and feeding of the sealant, which can be activated alternately, in a first feeding step and in a third feeding step, so that one of them provides flow continuity to an extrusion nozzle while the other one is in the reloading step. The first and second dosage assemblies are activatable, in a second swapping step that is intermediate with respect to the first and third feeding steps, simultaneously and jointly, one of them having a flow-rate ramp that passes from the steady-state value to zero and the other one complementarily having a flow-rate ramp that passes from zero to the steady-state value.

A dosage device for extruding a monocomponent or a bicomponent polymeric product, particularly for an automatic machine for forming a spacer frame, includes a first dosage assembly and a separate second dosage assembly for the dosage and feeding of the product, which can be activated, in a first feeding step and in a third feeding step, alternately so that one of them provides continuity of flow to an extrusion nozzle while the other one is in the reloading step. The first and second dosage assemblies are activated, in a second swapping step that is intermediate with respect to the first and third feeding steps, simultaneously and jointly, one of them having a flow-rate ramp that passes from the steady-state value to zero and the other one complementarily having a flow-rate ramp that passes from zero to the steady-state value.

An insulated glass assembly line generally includes a first and second automated lite picker, a washer, a vertical gas filling and wetting station, a robot, and an applicator station.

The invention relates to a multi-pane insulated glass (10), including at least two panes (15, 16), between which an edge seal (13) is inserted. The edge seal (13) has a peripheral spacer (14). The edge seal (13) separates a pane intermediate space (11) from a pane exterior space (12). A primary sealant (17) is provided between the peripheral spacer (14) and the panes (15, 16). The primary sealant seals the pane intermediate space (11) from the pane exterior space (12). An elastic seal (19) is provided which, seen from the pane intermediate space (11), is located in front of the primary sealant (17). The elastic seal provides sealing between the spacer (14) and a pane (15, 16).

A device for delivering a sealant material includes a first nozzle having a first nozzle head and a second nozzle having a second nozzle head. The first and second nozzle heads each independently have an outlet, an inlet opposite the outlet, and an open channel that extends through a body of the nozzle heads from the inlet to the outlet. The first nozzle is spaced apart from the second nozzle to form a space between the nozzle heads to allow a component to enter a first side of the device and exit a second side of the device while passing by the first and second nozzle heads. A notch is formed through the body of each of the first and second nozzle heads at a side where the component exits the device to distribute a sealant material onto each side of the component.
