  • Patent number: 10104784
    Abstract: A method for making an electronic product. The method includes processing a flexible substrate (e.g., a web) with the use of a tensioner having a vacuum plate and an indexer that intermittently moves the flexible substrate for processing. While a designated location of the flexible substrate is stopped at a processing location, a process is performed on the designated location. Wherein while the designated location is stopped at the processing location, the vacuum plate of the tensioner moves in an opposite direction of the transport direction.

  • Patent number: 9815262
    Abstract: The invention relates to a method of joining substrates. It is the object of the invention in this respect to join substrates of substrate materials together without having to exert an increased effort for a coating with additional coating processes to be carried out and to be able to achieve a good quality of the join connection in so doing. In the method in accordance with the invention a pretreatment of at least one join surface of a substrate to be joined is carried out in low pressure oxygen plasma prior to the actual joining. On the joining, a contact force acts on the substrates to be joined in the range 2 kPa to 5 MPa and in this process a heat treatment is carried out at an elevated temperature of at least 100° C. and at under pressure conditions of a maximum of 10 mbar, preferably <10?3 mbar.

  • Patent number: 5350469
    Abstract: To fill insulating glass panes with a heavy gas, one of the glass plates (40) of which the insulating glass pane is formed is initially only partly joined to the other glass plate (42) during assembly and to that end is flexed along one edge so that a gap is temporarily left between the glass plate (40) and the spacer (41) and a heavy gas can be introduced through that gap to fill the interior space of the insulating gas pane.

  • Patent number: 5282911
    Abstract: For the manufacture of curved insulating glazing panes having close tolerances of form, surface and thickness, the curved single glass sheets (2; 22) are brought to their desired shape via rigid suction mold plates (1; 21) and are glued together in this condition. A device suitable for carrying out this method consists of a press having two rigid plates (3; 23), template strips (4, 5; 24, 25) and positioning stops (8, 10; 28, 30) corresponding to the theoretical shape of the glass sheets, and also retractable suckers (15; 26) disposed between the template strips (4, 5; 24, 25), being mounted on the rigid plates (3; 23).

  • Patent number: 4747896
    Abstract: A protective superposed layer composite glass structure includes at least one glass plate, a polyurethane film, and a polyvinyl butyral sheet between the glass plate and the polyurethane film for attaching the polyurethane sheet to the glass plate. A polycarbonate plate is superposed against the polyurethane film. Alternatively, a polyester sheet can be superposed against the polyurethane film. A process for making a superposed layer composite glass structure includes surrounding the various layer elements with bands formed of a thermo-retractable material, calendering the layered elements surrounded by the bands at a temperature approximately in the range of 120.degree. to 200.degree. C. and subsequently subjecting the layered elements surrounded by the bands to the action of an autoclave at a temperature approximately in the range of 120.degree. to 200.degree. C. under a pressure approximately in the range of 10 to 15 bars.

  • Patent number: 4557776
    Abstract: A method of preliminarily pressing a bent assembly comprising a pair of bent glass sheets and a flexible interlayer comprising a first heating step performed without vacuum, a biasing step, an unbiasing step and followed by a second heating step performed simultaneously with an application of vacuum. When the assembly so prepressed is further laminated under heat and pressure, it develops fewer bubbles after a heat stability test involving exposure to high temperature for an extended period than assemblies further laminated under such heat and pressure conditions after a prepressing step that includes passing the assembly between rollers prior to the further lamination step.

  • Patent number: 4504341
    Abstract: The present invention relates to the simultaneous shaping and lamination of lightweight laminated transparencies, particularly those that are suitable for use in aircraft. The plies of an assembly to be shaped and laminated are assembled with additional elements to form a flexible cell of air impervious material. The cell includes an air impervious flexible wall defining a peripheral space around the assembly and porous material in the space. The cell containing the assembly is mounted over a vacuum mold and heated to sag the cell and its assembly to the contour of the mold while evacuating the cell while the cell and said assembly are exposed to atmospheric pressure.The cell is cooled while still under evacuation until the shape of the assembly is set, then is separated from the vacuum mold. The resulting assembly thus shaped and laminated is separated from the cell.

    Abstract: A method of bonding a first, vitreous sheet to a second sheet to form a laminate which includes the steps of bonding together the sheets using an adhesive material which is at most 250 .mu.m thick and has a viscosity in the range 15 to 300 poises, the adhesive being such that it is settable by evaporation of solvent or by hot or cold curing. The assembly is degassed by subjecting it to sub-atmospheric pressure at a temperature such as to maintain the adhesive viscosity within that range whereafter it is exposed to atmospheric pressure and the adhesive is caused or allowed to set.

    Abstract: A laminate assembly having rigid sheets about a thermoplastic interlayer has interfacial surfaces evacuated and peripheral edges sealed by applying localized vacuum and heat to only the periphery and marginal edge portions. A flexible heating blanket having marginally embedded heating elements overlies the laminate assembly and is biased theretoward by a flexible channel-shaped ring. The channel-shaped ring establishes a conduit about the periphery of the laminate assembly which is evacuated to remove entrapped air, and the heating element is energized to bond and seal the marginal edge portions of the assembly.

  • Patent number: 4364786
    Abstract: A process is disclosed for producing multi-layer laminates of glass and plastic of the type subject to nonsymmetrical thermal shear stress, such as flat or curved glass-plastic laminates or curved glass-plastic-glass sandwiches. Use of difunctional silane-treated glass and an aliphatic polyether polyurethane interlayer allows curing at temperatures low enough to minimize shear stresses which tend to cause delamination or shattering of the thin layer of glass in the finished part. The interlayer of aliphatic polyether polyurethane can be replaced by cured-in-place polyurethane having a polyether backbone, allowing processing at even lower temperatures.
