When being sealed, insulating glass blanks (5) are held in a sealing station (2) gripped at the base by grippers (17) of a gripper arrangement (16) and/or by suction heads (15) and rest at the top against a roller beam (7) fitted with rollers (8). As the insulating glass blank (5) is sealed, only the nozzle (11) of a sealing assembly (10) moves along the outer edge of the insulating glass blank (5), which is stationary during the sealing process. When the lower edge of an insulating glass blank (5) is sealed, grippers (17) engaging the lower edge are released and move away downwards. Sealed insulating glass is removed from the sealing station (2) by a removal robot (24) onto the side opposite the sealing assembly (10), moved to a temporary store and placed therein on A-bearing supports (29) and fan frames (30) sorted according to production lots.

Disclosed are a method and device for sealing insulated glass blanks, wherein the insulated glass blank is moved substantially continuously through a sealing station. When sections of the edge joint of the insulated glass blank that are oriented transverse or oblique to the conveying direction are filled with sealing mass exiting from a filling nozzle, the filling nozzle is likewise moved in the conveying direction. When sealing mass is introduced from the filling nozzle into sections of the insulated glass blank that are parallel to the conveying direction, the filling nozzle is not moved in the conveying direction or is moved in the conveying direction at a velocity V2 deviating from the velocity V1 at which the insulated glass blank is moved.

An apparatus for sealing an insulating glass unit includes a frame for supporting first and second clamping arrangements. The clamping arrangements support the insulating glass unit during a sealing operation. First and second dispensing assemblies are connected to the frame and movable relative to the frame. Each first and second dispensing assembly includes a nozzle for controlled dispensing of a sealant along a prescribed portion of the supported insulating glass unit during the sealing operation.

An insulating glazing unit having a first pane, a second pane, a third pane arranged between the first pane and the second pane, an outer pane interspace, an inner pane interspace, and a spacer is described. The spacer having a plastic profile with a first glazing interior surface and a second glazing interior surface, a first pane contact surface, a second pane contact surface, a primary sealing means, and a main member containing a sealing material and a drying material. The plastic profile includes a groove, into which the third pane is inserted and which runs parallel to the first pane contact surface and to the second pane contact surface. The plastic profile separates the outer pane interspace from the inner pane interspace. The main member is arranged in the outer pane interspace between the plastic profile and the primary sealing means, the main member being adjacent the plastic profile and the primary sealing means.

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.

A strand of sealing compound is expelled from a nozzle into an edge joint of an insulating glass element to form around it a contiguous sealing compound bead. The sealing compound bead is formed discontinuously from several segments. At least one first segment is formed by the relative movement in a first circumferential direction of the insulating glass element, and at least one second segment is formed by the relative movement in a second, opposite circumferential direction. Each connection of segments of the sealing compound bead which is situated on a longitudinal side section of the circumference of the insulating glass element is formed such that the strand of the sealing compound is applied in the region of the end of a sealing compound bead already situated in the edge joint and is formed by the relative movement away from the end.

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.

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.

The plastic profile includes a groove, into which the third pane is inserted and which runs parallel to the first pane contact surface and to the second pane contact surface. The plastic profile separates the outer pane interspace from the inner pane interspace. The main member is arranged in the outer pane interspace between the plastic profile and the primary sealing means, the main member being adjacent the plastic profile and the primary sealing means.
