Self-adhesive fabric for full-surface, removable bonding

of carpeting

1. Purpose of the invention

Carpets are increasingly part of the standard equipment of or multi-family houses, apartments, offices, restaurants and cafes, public buildings etc ..

The laying out or laying of the carpets can and will be different Methods carried out as follows:

a) full surface adhesive bonding

b) Bracing on a nail!

c) Installation on double-sided self-adhesive tape

d) Laying on recovery adhesive

e) Laying on grid-like materials completely impregnated with adhesive or partially coated, weakly adhesive nonwovens.

The purpose of this invention is characterized in that with this self-adhesive fabric for full-area, removable bonding of Carpet the laying method mc), d) and e) in one laying material can be summarized, carried out in one operation and all three advantages combined.

2. State of the art of laying carpet

2.1. Full-surface adhesive bonding

The most common method of laying a carpet is full-surface Bonding. The disadvantage is working with adhesives, which are often dangerous and contain highly flammable solvents.

However, it is particularly difficult to later pick up the firmly bonded Carpeting. Destroying the carpet and impairing the sub-floor cannot be avoided.

2.2. Tension on nail bars

Probably the best method. The disadvantage - very high costs due to complex work Accessories such as felt pads, etc. There is also damage to the sub-floor not to be prevented by fastening the nail ridges.

2.3. Installation on double-sided self-adhesive tape

This laying method is very dependent on the dimensional stability of a Carpeting. Large rooms can only open if the carpeting is very well located Laying tape to be glued. Is a good dimensional stability of the carpet not given, laying on laying tape is only carried out in smaller rooms of up to 20-30 square meters. A resumption is in use the correct installation tape is guaranteed.

2.4. Laying on recovery adhesive

This laying method is still controversial because it will be resumed at a later date could not always be guaranteed one hundred percent. The disadvantage is also working with adhesives and being very precise Dosage of the amount of adhesive per square meter, depending on the subfloor and carpet backing must be very precise.

2.5. Laying on grid-like materials or partially coated, weak adhesive fleece

This relatively new installation method is still viewed very critically in some cases, because the materials that are offered for this are not always the best.

The lattice-like materials, completely soaked in glue, have of course an even and equally thick adhesive coating on both sides, which is a disadvantage in many cases, because the adhesion to the carpet should be greater.

Some of the edges of these laying grids are not trimmed, which is the case with the Laying additional work such as cutting the edges and overlapping areas makes necessary.

The double-sided adhesive, strip-coated nonwovens have the disadvantage that the adhesive strength at the edges and at the butt seams of the carpet can be too weak. Here's a two-sided adhesive carpet tape is additionally required for backup. A major disadvantage of a fleece, however, is the possibility of splitting, i.e. the visible dividing of the fleece, when it is picked up again.

3. Description of the invention

The self-adhesive fabric for full-area, removable bonding von Carpet is supplied in roll form with different roll lengths.

So that the material doesn't stick together, it's on one side with a Protective paper (4) siliconized on both sides is covered. Can also be used as a cover a plastic film can be used.

The three main characteristics are:

Sheet 3

3.1. The carrier (1) for the adhesive is a fabric made of rayon or Cotton taken with special equipment. This special finish gives the fabric a stiffness so that it can withstand the Laying is adjustable.

Fabric can easily be cut to specific dimensions if this is for door entrances, Window and heating niches is necessary. Upon resumption, splitting or separation of the tissue is impossible.

3.2. The adhesive coating is applied in strips in parallel and lengthways. FIG. I shows the side which becomes free when the roll is unrolled and which is glued to the sub-floor during processing.

The number and spacing of adhesive coated strips (2a) is not identical with the number of strips and with the spacing of the other side of the fabric covered with protective paper.

Fig. II shows the side of the covered with siliconized protective paper (4) Fabric for full-surface, removable gluing of carpets. The carpet will later be glued to this side after removing the protective paper.

The connection between the carpet and the laying material should be larger than the connection of the laying material to the sub-floor.

For this reason the number of adhesive coated strips (2b) larger and the distance between each other smaller.

The greater adhesion of the laying material to the carpet is necessary, because at a later resumption of the carpet together with the laying material is lifted off the sub-floor.

Carpet and the fabric for full, removable gluing are rolled up together in a plastic film that was previously spread over the entire carpet.

3.3. Located on both edges (3a + 3b), i.e. on the left and right of the fabric On both sides there is a completely flat, continuously coated, wide adhesive strip.

These wide, fully and continuously coated strips of adhesive guarantee that the carpet also has sufficient adhesion to the sub-floor at the outer edges or door entrances.

The size and type of rooms to be carpeted do not matter Role. By having the wide strip on each side of the laying material can also be used when cutting or reducing the original width of the fabric Always ensure that a wide side strip comes to the outer edge or another desired location.

Sheet 4

A suitable arrangement can also be used for the seams of the carpet of the installation material to ensure that the carpet seam comes to rest on the wide coating surface and thus provides additional protection for the often critical carpet seam joints is.

An additional fixation with a double-sided adhesive tape such as in 2.5. is therefore not necessary.
