    专利说明:

    The invention relates to a method for assembling insulating glass blanks, in which the glass sheets are connected to the spacer by a heat-activatable adhesive, in particular a hot-melt adhesive.
    So far, an assembly of insulating glass of the above type has been proceeded so that the package of two or three discs with spacer joined between them or
    Spacers was placed in a hot press and after heating the glass sheets and the adhesive was pressed to its activation temperature to bring the glass sheets in contact with the heated adhesive.
    This method of operation has the disadvantage that in the interior of the insulating glass during cooling suppressing arises, resulting in a concave bulging of the glass sheets result.
    Another disadvantage is that in this operation a filling of the insulating glass with a gas other than air is not possible.
    The invention is based on the object to provide a method of the type mentioned available with the insulating glass of the type mentioned can be easily produced.
    This object is achieved according to the invention with a method having the features of claim 1. * · · «· * · # · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · t · «·· φ« «· ·
    Preferred and advantageous embodiment of the invention are the subject of the dependent claims.
    Since in the method according to the invention not the entire disc pack is heated by being introduced into a heated press, but only the spacer, the above-mentioned problems of known working techniques do not occur.
    Further details and features of the method according to the invention will become apparent from the following description with reference to the schematic drawings. It shows:
    Fig. 1 is a package of glass sheets and spacers prior to assembly of an insulating glass blank and
    2 shows an insulating glass blank after assembly according to the method of the invention,
    Fig. 3 shows a first variant, as can be applied to a spacer voltage and
    Fig. 4 shows a second variant, as can be applied to a spacer voltage.
    A package 1 for producing an insulating glass blank consists of two glass panes 2 (glass panels) and a spacer 3 interposed therebetween. Both side surfaces of the spacer 3 which face the glass panes 2 are lined with a layer 4 (strand) heat-activatable adhesive, for example a hot-melt adhesive, which is placed in a press for the assembly of insulating glass blanks 1. This press can at the same time be a press in which the insulating glass blank is mixed with a gas other than air (eg a noble gas) is filled.
    In order to heat the spacer 3 (of electrically conductive metal or at least partially of metal) and thus also applied to it adhesive strands 4 to activate them by heat, this is connected to a power source, so that this by the by the spacer 3 flowing current because of the electrical resistance of the material of the spacer 3 (this is an electrically conductive material) is heated directly. The heating is continued until the adhesive strands 4 have reached the temperature required for activating the adhesive 4. Then, optionally after filling of a gas other than air in the space in the press, the glass sheets 2 pressed against the side surfaces of the spacer 3 and the strands 4 provided there of adhesive and after cooling the adhesive 4 of the insulating glass blank from the Press removed.
    The insulating glass blank 6 is then conveyed, as is usual for the manufacture of insulating glass, to a sealing station, in which the outwardly open edge joint 5 of the insulating glass blank is filled with the * * • · m · · · · · »t«
    a sealant, such as a polysulfide-based mass is filled.
    In the embodiment shown in Fig. 3, the spacer 3 is bent into a frame which is still open at a corner 7, or there by a current non-conductive (electrically insulating) corner connector (for example, a corner bracket made of plastic) is connected. In the area of the corner 7, in which the two leading to this corner 7 leg 8 of the (frame-shaped)
    Spacer 3 electrically non-connected, so are electrically isolated from each other, the spacer 3, as explained above, connected to a power source 9 (DC or AC), so that the spacer frame for activating the applied to him, heat-activated adhesive 4 (Hot-Melt ) can be heated.
    In the variant shown in Fig. 4, the spacer 3 is a frame which is closed at all four corners, wherein the corners may have been made for example by integrally bending a spacer profile strip. In this case, voltage is applied to opposite corners 10, 11 (diagonally opposite corners), so that the spacer 3 is heated by the current flowing therethrough in the manner of resistance heating to activate the adhesive 4 applied thereto.
    The heat-activatable adhesives which can be used in the context of the present invention are known as hot-melt * ft * * * * «·· * ··« »« «* * * c * * ft · ·« * ··· · · «· · ·« «Ft ft« ·· known in the insulating glass industry. This is typically a thermoplastic sealant that can be processed at high temperatures (150 to 180'C).
    Considered in the present case are also butyl-based hotmelt adhesives as well as solvent-free hot-melt adhesives based on butyl rubber.
    In summary, an embodiment of the invention can be described as follows:
    In order to perform the assembly of insulating glass blanks 6, in which the spacer 3 is covered on both sides with a strand 4 of a heat-activated adhesive, the adhesive is thereby heated to its activation temperature, that the spacer 3 is heated by applying voltage in the manner of electrical resistance heating ,
