Abstract

The invention relates to an edge-protecting band (1) for protecting the edges of multilayer glass panes, particularly fire-resistant glass panes, said edge-protecting band being configured with multiple layers, i.e. an adhesive layer (3) covered by silicon paper (2), an aluminium foil (6) with an adhesive layer (7), and a sliding film (8) made of PET or PE (polyethylene), polyester or PP (polypropylene), and being outward-oriented in the use position. The aim of the invention is, amongst other things, to increase the stress resistance during installation at construction sites. Said aim is achieved by providing a layer (4 or 9) having increased vibration damping capability within the band interior.

Description

WO 2007/101499 PCT/EP200'7/000415 Edge Protecting Band for Protecting the Edges of Multilayer Glass Panes, in particular Fire Resistant Glass Panes The present invention relates to an edge protecting band of the type described in the preamble to Patent Claim 1.

Proceeding from an edge protecting band as described in the applicant's DE 20 010-U or DE-20 2005 001 617-U, which was developed for affixing to the edges of multilayer fire resistant glass panes, it is the objective of the present invention to make the border edges as resistant as possible to particles of dirt on the like.

Such resistance is necessary because the glass panes are subjected to a number of' stresses, especially during installation at construction sites. In particular, this can involve particles of dirt adhering to the edges before the glass panes are installed.
In the worst case, this could result in the destruction of the edge protecting band, so that moisture could penetrate between the individual panes and the alkali silicate or similar material that is installed between them.

In order to achieve this objective, the present invention is such that there isa type of layer that possesses increased damping capability, in particular a layer of foam within the band.
The layer of increased damping capability can also be formed from an adhesive layer that is of greatly increased thickness.

The provision of a layer of foam within the interior of the edge protecting band increases its damping capability to a particularly degree, i.e., no particles of dirt such as grains of sand or the like can be trapped without any problem without any damage being done to the outer foil that prevents the ingress of moisture. The foam acts as a sort of buffer.
Configurations of the present invention are described in the secondary claims.
Provision can be made such that the foam is formed from a PE foam film.

It is practical that the foam be formed from a closed-cell foam. Provision can also be made such that the closed-cell foam be in the form of a diffusion barrier and/or mechanical barrier as has been discussed above.

It has been shown that the polyester or polypropylene outer layer shall be provided with additional elements. One version of the present invention is such that a laminating adhesive layer is applied to the outer sliding film and an aluminum film be applied thereon.

The aluminum foil that is additionally applied can perform various functions.
According to the present invention, one such function is to make a type of adhesive agent available for a sealant that is applied at the installation site.

Additional features, details, and advantages of the present invention are described in the following description and in the drawings appended hereto. These drawings shovv the following:

Figure 1: a greatly enlarged cross section through an edge protection strip;
Figure 2: as in Figure 1, another configuration of an edge protection strip;
Figure 3: as in Figure 1, another configuration of an edge protection strip Figure 4: as in Figure 1, an additional variant of the edge protection strip according to the present invention.

The drawings show the construction of an edge protection strip in which the thickness of the individual layers is greatly exaggerated for illustrative purposes.

In the example shown in Figure 1, the construction of the edge protection strip, which bears the overall number 1, consists-as viewed from bottom to top-of a layer 1 of silicon paper 2, an adhesive layer 3, and a damping layer of PE foam 4 that is covered by an adhesive layer 5.
In the example shown according to Figure 1, wherein the construction is identical to that in Figure 2, the adhesive layer follows an aluminum foil 6, a laminating adhesive layer 7, and finally the outer layer 8 that can, for example, be of polypropylene or polyester.

Depending on the type of the outward oriented protective film 8, this can be initially treated with an adhesive lacquer, ionized, or the like in order to enhance the adhesion of the adhesive lamination. This is not unusual in the case of films of this kind.

The thickness of the respective layers can be as follows:
2 (standard thickness) 3 (20 to 100 m) 4 (10 to 500 m) (20 to 100 m) 6 (20 to 100 m) 7 (3 to 30 m) 8 (20 to 100 m) Figure 2 shows a modified example of an edge protection strip la wherein the satne elements bear the same reference numbers as in Figure 1 with an additional lower case letter "a."

In the example shown in Figure 2, a silicon-paper covering 2a follows an extra thick adhesive layer 9, the damping characteristics of which is indicated (solely for reasons of simplicity of representation) by small arrows.

The damping, extra thick adhesive layer 9 is covered by aluminum foil 9a. This is followed by a laminating adhesive layer 7a and an outer layer 8a, e.g., of propylerie. In theory, this could also be of a polyethylene material.

The thicknesses of these layers are as follows:

2a (standard thickness) 9 (50 to 300 m) 6a (20 to 100 m) 7a (3 to 30 m) 8a (20 to 100 m) In Figure 3, as far as the layers 2 to 8 are concerned, the edge protecting strip lb is built up in the same way as the edge protecting strip 1.

In addition, in this embodiment, an adhesive layer 10 is laminated on to the outer polyester or polyethylene film 8, and once again there is an aluminum film 11 on this. In this embodiment this forms the outer layer.

The thicknesses of the individual layers of the edge protecting strip 1 c are as follows:
2b (standard thickness) 3b (20 to 100 m) 4b (10 to 500 m) 5b (20 to 100 m) 6b (20 to 100 m) 7b (3 to 30 m) 8b (20 to 100 m) (3 to 50 m) 11 (5 to 100 m) Finally, Figure 4 shows the same edge protecting strip 1 c as in Figure 3, although here an outside, binary sealing compound 12 is also used. This can be applied to the prepared panes just before installation.

The thickness of this layer of butyl or binary sealing compound 12 will depend on the particular application.

The embodiments of the present invention described heretofore can, of course, be modified in many respects without departing from the underlying concept. This applies, in particular, to the above quoted thicknesses of the damping layer and the sliding film that faces outward.
