In the embodiment according to claim 12, the double-sided adhesive spacer strip each has a different thickness, which allows the distance between the discs can be individually adapted to the requirements. In addition, the differently thick double-sided adhesive spacer strip is arranged in an indefinite scheme and / or in an indefinite order from disc to disc, which can be customized depending on the application, the distance and the arrangement of the discs individually.

Several Embodiments of the invention are in the drawings and will be described in more detail below. Show it:

1 schematic sectional view of a laminated glass packet packet fragment,

2 schematic sectional view of a laminated glass packet fragment with different decency between the panes,

3 schematic sectional view of a laminated glass packet fragment with foil laminated disc packages and with different decency between the discs and different thickness discs.

The laminated glass and / or bulletproof glass consists of at least two panes 1 whose spaces between the discs 1 with a multi-component cast resin 4 bubble-free and the thickness of the individual slices 1 vary among each other. To further increase the strength of the laminated glass, a second or further disc 1 and / or a second or further foil laminated laminated core 8th congruent to the first or previous disc 1 and / or to the first or previous foil laminated disc package 8th be laid on, with regularly or irregularly changing a casting resin layer 4 or a film layer 7 is available.

To further increase the strength of the laminated glass, the individual discs exist 1 made of float glass and / or chemically tempered glass and these discs 1 are arranged regularly and / or irregularly alternating in the composite and / or at least one disc 1 is through a polycarbonate disc 9 or by a polycarbonate film 9 replaced. The chemically hardened glass is added by internal exchange on the surface under compressive stress. A flat glass containing sodium ions, e.g. B. float glass, is immersed in a potassium nitrate melt. During the residence time of the glass in this salt solution at about 450 degrees C, the exchange of small sodium ions from the glass surface with the larger potassium ions from the salt solution occurs. This leads to an increase in the surface tension of the glass. This achieves a considerably higher breaking strength. For example, untreated float glass has a mechanical load capacity of approx. 50 N / mm. On the other hand, chemically tempered glass is 300 to 350 N / mm.

Thus, this disc composite is better able to absorb the projectile energy of a projectile. The breakthrough of Scheibenver Federal by a bullet is thus much more difficult or completely prevented.

The Combination of chemically tempered flat glass with the high Breaking strengths of at least 300 N / mm with polycarbonate sheets, z. B. 1 mm to 3 mm, or increase corresponding polycarbonate films the strength essential. Depending on the application, so several Packages of this type laminated with various glass thicknesses, optionally with 0.36 mm PVB film or multiples thereof or in cast resin lamination, z. B. with a layer thickness of 2 mm.

The laminated glass package and / or bulletproof glass package 5 can also additionally a frame 6 own, with the frame 6 at least the cumulative width of a spacer band 2 and a circumferential groove 3 has.

In the method of making laminated glass and / or bulletproof glass from at least two slices 1 or at least two discs superimposed with an introduced release agent, bent at about 550 ° C to 600 ° C and cleaned after cooling 1 with a glass thickness of 2 to 6 mm becomes a double-sided adhesive spacer tape 2 from about 0.25 mm to 10 mm thick on a disc 1 glued at about 0.5 to 20 mm from the edge. Thereafter, the protective strip on the spacer strip 2 away. A second or further disc 1 becomes congruent with the first or previous disc 1 hung up. In the resulting circumferential groove 3 from about 0.5 mm to 20 mm is silicone 3 injected. The silicone 3 binds off chemically for about 24 hours. The space between the discs 1 is made with a multi-component cast resin 4 filled bubble-free. The casting resin 4 is manually mixed with a cannula with a cartridge and a hand gun and / or with a known automated mixing station and a pneumatic spray gun in the space between the discs 1 pressed and / or sprayed. During filling with casting resin 4 will be the disc package 5 tilted. There are air escape openings at the upper end. The air bubbles collecting at the edge can be sucked off with a known vacuum method. After filling with the casting resin 4 the curing process takes place. This takes about 24 hours. The disk packages remain 5 in a stable position. To underpin the curing process are the disk packages 5 heated to 50 ° C for about 24 h.

As in 2 can be seen, has the double-sided adhesive spacer tape 2 each a different thickness. The differently thick double-sided adhesive spacer tape 2 can in a certain scheme and / or an indefinite order of disc 1 to disc 1 be arranged. Laminated glass or armored glasses produced by this process have good thermal shock resistance and high impact strength. The casting resin 4 binds with glass breakage all glass splinters. The cast resin layer 4 has a certain thermal insulation effect and thus leads to energy savings when used accordingly. Temperature differences in rooms do not cause dew point drops. Laminated glasses with cast resin lamination are considered soundproof glasses, since the casting resin layer 4 sound-absorbing effect. This laminated glass is machinable. It can be cut, sawn, drilled and sanded. Laminated glasses with cast resin lamination have a high transparency.

In 3 is on a single disc 1 and / or on a laminated with foil package 8th from at least two slices 1 a double-sided adhesive spacer tape 2 from about 0.25 mm to 10 mm thick on the top disc 1 of the laminated with laminated disk package 8th or on the single disc 1 glued at about 0.5 mm to 20 mm from the edge. After removing the protective strip on the spacer strip 2 becomes a second or further disc 1 or a polycarbonate disc 9 and / or a second or further foil laminated laminated core 8th congruent to the first or previous disc 1 and / or to the first or previous foil laminated disc package 8th applied, with regularly or irregularly changing a Gießharzschicht 4 or a film layer 7 is present and the thickness of the film layer between 0.2 mm and 7 mm. At least one foil layer 7 consists of a polycarbonate film 9 , In the circumferential groove 3 of the spacer band of about 0.5 mm to 20 mm becomes silicone 3 injected. After a setting time of the silicone 3 by about 24 h, the space between the panes becomes 1 with a multi-component cast resin 4 filled bubble-free. The air bubbles collecting at the edge are sucked off. The entire laminated glass package and / or bulletproof glass package 5 remains stable for about 24 hours for the curing process. The disks 1 consist of float glass and / or chemically tempered glass. They can be arranged regularly and / or irregularly depending on the application.
