Abstract: An insulating glass pane structure including two glass panes is formed by providing an elastoplastic strip from a delivery reel, where the elastoplastic strip has a varying dimension along its width including a first, nominal width section and a second, reduced width section that is smaller in width than the nominal width section. Side surface area portions of the nominal width section of the strip are coated with a first adhesive glue, and side surface area portions of the reduced width section of the strip are coated with a second adhesive glue that is diffusion-proof against water vapor. One side surface of the strip is pressed against a first glass pane to form a spacer, the strip being pressed close to an edge of the first glass pane, and the second glass pane is applied and pressed to form the glass pane structure.

Abstract: A device for testing tempered glass plates using a heat-up phase, a holding phase and a cooling phase has at least one chamber in which the glass plates which are to be tested, standing in harp racks, are placed. The device has a fan with a heating and cooling elements which is connected on the intake side to the top end of the chamber and on the pressure side to the bottom end of the chamber underneath a perforated bottom which borders the chamber to the bottom. The perforated bottom can be a stationary, sloped bottom or a conveyor element with a perforated transport belt. Next to the bottom is a discharge channel for glass pellets which form when a glass plate breaks during the test cycle.

Abstract: To ensure that the support force which is dependent on the pressure of a support fluid is essentially the same also in the edge area of an article (9), especially sheets of (flat) glass, which is to be held or transported, as the support force in the middle area of the surface of the article (9), the device (1) as claimed in the invention on at least one support wall (3 or 5) provides for feed openings (21) to which drain openings (23) are directly assigned.

Abstract: A blade is used to cut through a film between the panes of laminated glass in the area of a gap produced in the laminated glass the blade is provided on a holding device and can move along the gap. The holding device includes swiveling carrier on which there is a holding part for the blade with a vertical adjustment capacity. The blade is first placed next to the gap on the top of the top pane of the laminated glass. The vertical alignment of the blade is ascertained with a rule for determining the thickness of the laminated glass. Then the holding device is adjusted by a motor such that the blade falls into the gap. When a sufficient immersion depth of the blade into the gap is ascertained via the rule, the film is cut.

Abstract: A device for the dimensionally accurate application of an elastoplastic spacer strip onto a glass pane is disclosed. The device includes a compensating or tailback section between a first adjustably driven pair of rollers and a second adjustably driven pair of rollers, as well as a sensor for recognizing the position of the strip in the compensating section. The device is designed such that the spacer strip is not withdrawn from the storage drum but, instead, is unwound in a manner free from any tensile stress. The spacer strip, furthermore, is kept free from tensile and shearing stresses on the route up to being pressed onto a glass pane, despite the fact that the application speed will inevitably fluctuate several times between zero and a maximum value while edges of the glass pane are covered mechanically.

Abstract: A method for the dimensionally accurate application of an elastoplastic spacer strip onto a glass pane intended for producing an insulating glass unit is that the spacer strip is not withdrawn from the storage drum but instead it is unwound in a manner free from any tensile stress and that the same is kept free from tensile and shearing stresses on the further route up to the pressing onto the glass pane, this being despite the fact that the application speed will inevitably fluctuate several times between zero, and a maximum value while edges of the glass pane are covered mechanically. The apparatus for performing the method therefore comprises a compensating or tailback section (3) between a first adjustably driven pair of rollers (1) and a second adjustably driven pair of rollers (9) as well as a sensor for recognizing the position of the strip in the compensating section.

Abstract: A device for heating plates of glass (3) which are hardened or deformed, includes two ceramic heating plates (1) between which a plate of glass (3) is arranged. Compensation plates (20) are associated with the heating plates (1) at a distance therefrom, in addition to heaters (6) which are arranged close thereto. The heaters (6) are accommodated in housings (11) which are defined on one side of the heating plates (1). Holes (8) are provided in the heating plates (1). Gas is fed through the holes into the housing between the heating plates (1) and the compensating plates (2). The gas is heated by flowing past the compensating plates (20) and forms gas cushions (7) on both sides of the plate of glass (3) which hold the plate. The plate of glass (3) is heated in a homogenous manner by radiation and convection.

Abstract: A method and apparatus for applying an elastoplastic strip as a spacer in the production of insulating glass panes comprising a supply winder for the strip, several driven strip guide rollers, and a pressing head for the strip which is movable relative to a first glass pane. In contrast to the state of the art, an elastoplastic band is used whose side surfaces are not yet coated with an adhesive. The adhesive is applied only shortly before the application of the strip onto its two side surfaces. For this purpose, mutually opposing nozzles that coat the side surfaces of the strip with an adhesive are arranged between the supply winder and the pressing head.

Abstract: A device for working of glass panes (1) has a support (5) for the glass panes (1) and a nozzle (2) from which a water jet emerges for cutting the glass panes (1). The nozzle (2) can be moved on a guide (8) parallel to the plane of the support (5). The tool (12) for working of the cut edges of the material plates (1) can likewise be moved on the guide (8) of the nozzle (2) and is preferably mounted on the same carriage (9) which can be moved on the guide (8), as the nozzle (2). This simplifies not only the technical structure of the device, but also shortens the working time, since the glass pane (1) need not be transported to another device for finishing. Moreover, essentially the same control program as for the water jet cutting can be used for finishing.

Abstract: A device for machining a glass plate (5) is provided with a lifting element (10, 11) which is used to lift the glass plate (5) from a transport device (3) located on a lower edge of a supporting wall (1), during the machining process. The lifting element (10, 11) includes lifting fingers (10) provided with clips (15) which can be applied to the lower horizontal edge (7) of the glass plate (5), in order to positively connect the lifting element (10, 11) to the glass plate (5). Both a drive for lifting and lowering the lifting element and a drive for horizontally displacing the same are associated with the lifting element (10, 11), such that the glass plate (5) can be displaced during the machining process, without slipping and without any time delay.

Abstract: To prevent formation of a welding bead in the area of the weld on at least one wall when hollow section strips (1) are being joined by butt welding, on at least one wall of the ends of the hollow section strips (1) to be joined to one another by welding, edges (7) are produced which are set back relative to the end faces (5) of the hollow section strips (1) and the ends of the hollow section strips (1) are moved so close to one another in the execution of the welding process that the edges (7) touch and the welding process ends as soon as the edges (7) touch one another.

Abstract: A device for working of material plates (1), such as glass panes, has a supporting member (25, 26, 29) for the material plate (1) and a tool (12, 18) for working the material plates (1). The supporting member (25, 26, 29) has paired supporting elements (25?, 25?, 26?, 26?, 29?, 29?) with supporting surfaces (27?, 27?, 30?, 30?) facing one another, between which the material plate (1) is held. There are openings (31) for liquid emerging under pressure in the supporting surfaces (27?, 27?, 30?, 30?). The material plate (1), especially the glass pane, is therefore not mechanically supported, as is conventional in the prior art, but uses a liquid film which is formed under pressure in the gap between the material plate (1) and the supporting surfaces (27?, 27?, 30?, 30?) of the supporting elements (25?, 25?, 26?, 26?, 29?, 29?).

Abstract: In a system for cutting glass sheets into shapes there is at least one cutting site (A, B). In order to align the glass sheet which is to be cut or the glass sheet shape into a defined position, on the edge of the support surfaces (I and II) there are contact edges (21, 44, 45). In order to move the glass sheets and the glass sheet shapes along the contact edges (21, 44, 45), the glass sheets or glass sheet shapes which adjoin the contact edges (21, 45) are coupled by force-fit to the conveyor belts (20) which are provided in the area of the contact edges (21, 45) and then moved for example to the cutting sites (A, B).

Abstract: In a system for cutting glass sheets into shapes there is at least one cutting site (A, B). In order to align the glass sheet which is to be cut or the glass sheet shape into a defined position, on the edge of the tables I and II there are contact edges (21, 44, 45). In order to move the glass sheets and the glass sheet shapes into contact with the contact edges (21, 44, 45) the tables I, II are aligned sloping down toward the contact edges (21, 44, 45) so that the glass sheets and glass sheet shapes slide on air cushions produced between the glass sheets or glass sheet shapes and the tables (I, II) in contact with the contact edges (21, 44, 45). The glass sheets or glass sheet shapes which adjoin the contact edges (21, 45) are coupled by force-fit to the conveyor belts (20) which are provided in the area of the contact edges (21, 45) and then moved to the cutting site (A, B) which is located following the table (I, II).

Abstract: In order to allow a glass plate (26) to fall over out of the position which is tilted somewhat to the vertical into an essentially horizontal position, the glass pane (26) standing up with its lower edge (28) on the conveyor device (22) and with its upper edge (29) resting against a support member (40) with rollers (44) is moved into the initial position. By moving the support member (40) away from the upper edge (29) of the glass pane (26) it is allowed to fall down to the rear so that it comes to rest on the support surface of the table (2). From this support surface which can be made as an air cushion or as a span with transport belts or rollers, a glass pane (26) which points up with its “nicer” side (27) can be delivered to further treatment, for example to a downstream device (18).

Abstract: A unit for dividing glass sheets has two tables (I) and (II) and two separation sites (A) and (B). The table (I) which is located in front of the first separation site can be aligned to slope obliquely down toward the contact edge for moving the glass sheets located on it in the direction to this contact edge. The glass sheets adjoining the contact edge are moved gradually to the separation site and are divided there in the X direction. On table (II) there are two conveyor devices which can be independently actuated. Using these two conveyor devices, glass sheet shapes which travel onto the table (II) can be independently but simultaneously supplied to the separation site (B) so that it is possible to further divide these glass shapes on the given dividing lines in the separation site (B) at the same time or overlapping in time into glass shapes.

Abstract: A device for producing heavy gas-filled insulating glass sheets (62, 64, 60) has two plates (4, 6), between which the insulating glass sheet (62, 64, 60) which is to be filled can be located. On the vertical edges of the plates (4, 6) there are sealing devices (12) to seal the space (10) between the plates (4, 6). On the lower edge of the plates (4, 6) there are a conveyor means (40) for insulating glass and a channel (44) for the supply of heavy gas into the space (10) between the plates (4, 6) and into the interior (60) of the insulating glass sheets (62, 64, 60). In one of the plates (4, 6) there is a seal (20) which extends solely transversely to the plane of the plate (4) from bottom to top essentially vertically and which is located for example in the (lengthwise) middle of the plate (4).

Abstract: A bending head for bending of metallic hollow profile strips (2) in the production of spacer frames for insulating glass panes has a bending abutment (5) and a bending cheek (7). The bending abutment (5) can be placed by swivelling against one side of the section of the hollow profile strip (2) to be bent, conversely the bending cheek (7) can be placed from the outside against the hollow profile strip (2). In the execution of the bending process the bending abutment (5) and the bending cheek (7) are moved at the same time and hold the section of the hollow profile strip (2) to be bent between themselves.
