A method for the production of a frame-shaped spacer for insulating glass panes which includes individual glass plates spaced by adhering the spacer to them, including the steps of selecting a metallic hollow profile bar, which includes an outer wall, an inner wall opposite the outer wall and two flanks which are parallel to one another, the inner wall and the outer wall being narrower than the hollow profile bar, and forming the spacer from the hollow profile bar, so that their flanks face the glass plates.

Spacer for insulating glass panes

The invention relates to a method for producing a corner of a frame-type spacer for insulating glass panels by (a) making a metal hollow profile rod available, which rod has an outer wall, two parallel flanks, and an inner wall, (b) indenting the inner wall and the two flanks in the position of the hollow profile rod where the corner is supposed to be formed, and (c) bending the hollow profile rod by a defined angle.

In order to configure an insulated glass pane, two individual glass panes are glued to each other by means of a frame-shaped spacer. For this purpose, a sealant is provided in joints between two flanks of the spacer and the two adjoining glass panes. The joints on the interior of the insulated glass pane are open and contain a mass, which has a surface facing the interior of the insulated glass pane and in which a drying agent is embedded.

What is described is a linear connector for connecting two opposing ends of a hollow profile member for the purposes of forming a frame-like spacer for the production of insulating glass panes. The linear connector includes a top side, a bottom side and two side surfaces, connecting the top side and the bottom side of the linear connector. The linear connector is provided with a midsection in a middle area of the linear connector, with the midsection extending at least along an entire width of the top side or of the bottom side of the linear connector.

According to the invention, a suspended blade () is provided as a seal which is active between the plates (,), said blade comprising a suspension () which can be displaced along the upper edge of the first of the two plates (), the distance of the suspension from each plane being changeable. The front side of the first plate () lies in said suspension and the blade () is provided, at least on one side, with a reversible yielding sealing compound.

A method for providing a molded body and for inserting said molded body into a hollow bar section with a cross-section of a predetermined width and height that remains constant over its length, from which a frame-type spacer for insulating glass panes is subsequently configured, the molded body bridging a gap in said spacer. According to said method, a strand-type semi-finished product with a cross-section that remains constant over its length is provided; the semi-finished product is positioned in relation to a separation tool in such a way that a predefined section of the semi-finished product lies on one side and the remaining section of the semi-finished product lies on the other side of a separation plane of the separation tool and the length of the predefined section that is measured in the longitudinal direction of the semi-finished product is adapted to the inner width of the hollow bar section.

A device for conveying insulating glass panes, which are slightly inclined from the perpendicular, is provided with a horizontal conveyor ( ) on which the insulating glass panes stand, and with a supporting device ( ), which extends above and parallel to the horizontal conveyor ( ). The supporting device ( ) defines by one or more supporting elements a pane movement plan ( ) against which rest the insulating glass panes of the horizontal conveyor ( ). The horizontal conveyor ( ) has two parallel and synchronously drivable conveying elements ( ), supporting surfaces ( ), which are aligned substantially vertical to the pane movement plane ( ). The distance of one of the conveying elements ( ) from the other conveying elements ( ) is variable. The conveying elements ( ) are movable independently of one another transverse to the pane movement plane ( ).

The invention describes a machine for filling the edge joint of insulating glass panes with a semi-liquid to paste-like sealing compound, consisting of a main constituent and a secondary constituent, which are different in chemical terms and in terms of their viscosity, having two pumps (,) which convey the two constituents from two reservoirs (,) into separate intermediate storage chambers (,), and having separate, synchronously driven volumetric feed metering pumps (,) for conveying the constituents in a predetermined composition to a mixer (,) and then on to a nozzle (,), the nozzle and the mixer belonging to one sub-assembly which is movably mounted as a whole on a frame of the machine. According to the invention, there is provided a gear pump (,), driven by a servomotor, as metering pump for the main constituent in combination with a piston pump (,), which serves as a metering pump for the secondary constituent and whose piston (,) is driven by a second servomotor (,), both of which preferably are part of the movable sub-assembly.

For filling the insulating glass panes with a heavy gas, one of the glass plates (40) which are to constitute the insulating glass pane is only partly joined to she other glass plate (42) before the assembling, particularly in that said one glass plate is bent so that a gaplike opening temporarily remains between the glass plate (40) and the spacer (41) and the interior space of the insulating glass pane can be filled with a heavy gas through said gaplike opening.

Process and apparatus for assembling insulating glass panes which are

The apparatus comprises a buffer container (1) for receiving the pasty substance of high viscosity, a feed line (11), through which the buffer container (1) can be refilled with the substance, a pressure generator (2 to 5), by which the substance in the buffer container (1) can be pressurizes, a nozzle (10), which is close to the buffer container (1), a pressure sensor (43) downstream of the pressure generator, and a controller (44). As a result, the metering rate can exactly be controlled close to the nozzle (10).
