Workpiece for attachment to a work surface and method for manufacturing the workpiece

130061/0338

The invention relates to a workpiece for attachment to a work surface and to a method for the production of the workpiece.

The invention relates in particular to workpieces in the form of carpets and carpets and generally on workpieces that are attached to a work surface or support surface, such as a floor surface will.

When fastening workpieces in the form of coverings, such as carpets and carpet tiles, on supporting surfaces, such as floor surfaces, an adhesive which has a property of becoming tough becomes in many cases and harden to a hard joint, applied to the soil. The carpet pieces or carpet tiles will be then placed on top of the glue and moved into position before the glue becomes too tough or sticky for a processing will. The adhesive is then allowed to dry out hard, leaving the carpet or carpeting is connected in a substantially permanent manner to the ground. Removal of the carpet after a certain amount of time Longevity is difficult because the carpet backing material is very firmly adhered to the floor. A removal of the Carpet or carpeting causes the backing of the carpet to tear, leaving parts on the floor and the adhesive that is glued to the floor remains on the floor and only with difficulty to be removed.

130061/0336

In order to avoid these disadvantages, it is also known to use a dry adhesive bonding material with a lattice construction which is inserted between the floor and the carpet or carpet to ensure all adhesive surface contact with both the floor and with
decrease the carpet. Such a method and a connecting material is disclosed in DE-OS 27 23 239
by the same applicant, to whom reference is expressly made.

This known connecting material is used in the form of either separate sheets or tapes, and the
Threads or strands of the bonding material are coated with a dry or pressure sensitive adhesive which allows the bonding material to be easily removed from the floor along with the carpet that is laid over it
without damaging the floor. Of the
Carpet is firmly anchored to the floor and the properties of the connecting material brought about by the use of the dry adhesive or pressure-sensitive adhesive enable precise alignment of seams and precise
Laying out individual pieces of carpet because they are easy
Lifting the carpet from the connecting material during
of laying. It has been found that such a bonding material remains on the ground for a long time
Periods of time and still can be removed without undesirable damage to the floor or tearing of the carpet.

The invention is based on the object of an improved Workpiece of this type for attachment to a work surface and a method for producing this workpiece create a further simplified handling of the work

130061/0336

Piece allows for laying and, if necessary, for a later removal.

This object is achieved by the invention specified in claims 1 and 12, respectively.

Advantageous refinements and developments of the invention emerge from the subclaims.

According to one embodiment, the workpiece according to the invention forms a one-piece connection material-Z carpet construction, wherein the section of bonding material is permanently embedded in the lower surface of the carpet section and is made to adhere to it. In this way the connection material / carpet construction attached to or removed from the floor without the bonding material separating from the carpet.

According to a preferred embodiment of the invention, the carpet section and the connecting material section essentially permanently adhered to one another at the time the carpet material was cut is used to form carpet tiles.

In one embodiment of the invention, the connecting material section is substantially permanently bonded directly to the first or main carpet backing layer of the carpet.

The invention is explained below with reference to exemplary embodiments which show a workpiece in the form of a piece of carpet, explained in more detail.

In the drawings is an embodiment of the invention in the form of a connecting material-Z-carpet construction 1, including a section of carpet A and a section of bonding material B, which are essentially are constantly made to adhere to one another.

The carpet section A has the usual pile 2, which can be cut open or not and which can be knotted, woven or otherwise manufactured and embedded in a primary carpet backing layer, supported or anchored, which can consist of a woven or non-woven material. Under the primary or first carpet backing layer 3 is a secondary or second carpet backing layer permanently attached thereto 4 ", which consists or is made of elastic material, such as foam rubber, a fabric., made of jute or woven synthetic material or made of smooth rubber or in the form of a plastic cover.

The connecting material section B is embedded in the underside of the carpet section A and is permanent on this attached. The connecting material portion B comprises a connecting material 5 and a removable release protective layer 11. The connecting material 5 preferably consists of strands or threads 8 made of a natural or synthetic fiber (such as paper) or from other raw material that is woven, knitted or otherwise in the form of a lattice-like or any other suitable construction. It is understood that the connecting material from any may be made of another suitable material.

The connecting material 5 forms a plurality of spaced apart frame members 6 and a plurality of Foot or rib parts 7. These foot or rib parts 7

130061/0336

are designed so that they form the frame elements of the connecting material 5 a short distance from a floor 10 or any other work surface. The strands 8 of the connecting material are coated with a dry adhesive or pressure-sensitive adhesive 9, as shown in FIG. 6 is shown.

The connecting material 5 has an upper surface, which is adhered to the lower surface of the carpet backing layer 4 of the carpet section A, and it also has a lower surface which is made to adhere to the floor 10. Because of the glue and. of the intense pressure exerted is the upper surface of the bonding material 5 into the lower surface of the carpet backing 4 embedded and essentially permanently attached to this. The glue between the top surface of the bonding material 5 and the lower surface of the carpet backing layer 4 is substantially permanent and forms a strong connection (as will be explained in more detail below), so that as a result the connecting material section B and the carpet section A become an integral part.

The dry glue or pressure sensitive adhesive 9 »which is on the bottom Surface of the connecting material 5 is located, allows a secure anchoring of the connecting material 5 to the ground

10 and at the same time enables the connecting material / carpet construction to be easily lifted off the floor 10.

With this arrangement, after peeling off the protective film

11 to expose the connecting material 5 coated with the dry adhesive, the connecting material-Z carpet-

130061/0336

Construction are placed on the floor 10 so that the dry adhesive 9 on the lower surface of the connecting material 5 rests on the floor so that the entire connecting material / carpet construction on the Floor 10 is made to adhere. Because the foot or rib parts 7 of the connecting material 5 on the The floor 10 rest, and the frame elements 6 of the connecting material 5 are slightly above the floor, the connecting material 5 is merely made to adhere slightly to the floor. The adhesive effect is sufficient to create a secure connection so that the connection material / carpet construction does not get under the normal load, but it is easily enough for the workpiece, i.e. the carpet, to be easily removed and can be lifted off without tearing or damaging the floor.

When the carpet section A is to be removed, the connecting material 5 is lifted from the floor 10, and because this connecting material forms an integral assembly with the carpet section A, that entire connecting material 5 together with the carpet section A, with which the connecting material. one piece is formedj away. excess amounts of dry glue or pressure-sensitive adhesive 9 on the connecting material 5 do not remain on the floor 10, and neither do they like parts of the pile 2 or the carpet backing layers 3 or 4, so that the floor after the removal of the bonding material / carpet construction is relatively clean.

In order to protect the dry adhesive or pressure-sensitive adhesive 3 on the connecting material 5 and to prevent permanent adhesion of the adhesive 9 to other carpets or objects, the protective separating layer 11 is a thin one

130Ö61 / Q336

Polyethylene film can be placed over the bonding material 5 until the carpet is to be used. on an arrow 12 can be arranged on this protective separating layer 11, which shows the weaving direction and serves as an indication, so that the carpet is laid in the right way.

The preferred method of making the one-piece tie / carpet construction is shown in the figures 7 and 8 and comprises pressing together a section of carpet A and a section of bonding material B under high pressure so that the adhesive 9 on the upper surface of the bonding material 5 into the lower surface the carpet backing layer 4 is securely embedded and made to adhere to it. As shown in Figures 7 and 8 is a preferred embodiment of the Method of making the joint / carpet construction for use in the form of a carpet tile in applying pressure during the carpet cutting process. The carpet section A is under one Cutting mechanism 15 moved with a movable pressure plate 16, which is divided into a number of printing squares 16A; is divided, with a number of knives arranged around the circumference of each printing square 16A of the printing plate 16 around is. The connecting material section B is placed on a support plate Ϊ8, which is at a distance below the pressure plate arrangement 16 is arranged and has devices for receiving the knives 17 when the pressure plate 16 is lowered. The carpet section A and the connecting material section B can be supplied from a roll (not shown) can be fed out.

When the joining material section B and the carpet section A in their position under the cutting mechanism

are located, the pressure plate 16 of the cutting mechanism depressed so that the Meseer 17 cut the carpet and bonding material sections into squares The extent of the pressure of the pressure plate 16 is such that each pressure square 16A exerts a pressure on the carpet and exerts connecting material sections A and B and these two sections firmly between the print squares 16A and the plate 18 together. This pressure is such that the adhesive on the strands 8 of the connecting material 5 is firmly attached to the second carpet backing layer 4 adheres to and is embedded in them so that an essentially permanent relationship results in such a way that that an integral assembly is formed.

It can be seen without further ado that the square shape of the knife 17 of the printing plate according to the drawings serves only to explain the case when carpet tiles are to be produced. The shape of the knife for making the combined assembly can of course be changed to any desired To achieve the shape of the carpet pieces.

The one on the joining material section B and the carpet section A pressure exerted is sufficient to force the connecting material 5 onto the second carpet backing layer with great force 4 to be attached and embedded in this, so that there is a permanent one-piece arrangement. this can be achieved without the application of heat. However, it is also possible to apply heat to the connecting material and to adhere the carpet sections to one another so that there is a firm connection "in this" case the heat can be applied to the connecting material section and the. ·. Carpet section are supplied, and / or the heat can be fed to the printing plate mechanism 15 of the cutter, if desired.

130061/0336

FIG. 9 shows a method for producing a similar connection material-Z carpet construction for carpet material with wide loom widths instead of individual carpet tiles, as in FIGS. 7 and 8. In this case, the carpet section A with the pile 2, the first and second carpet backing layers 3 and 4 as well as the connection material arrangement B with the connection material 5 and the protective separating layer 11 both moved through between two pressure rollers 19. The pressure rollers 19 exert sufficient pressure on the two sections A and B so that the bonding material is adhered to and embedded in the lower surface of the second carpet backing layer k with great force to form a practically permanent one-piece assembly. In this case too, the connection can be carried out without the application of heat, the pressure being sufficient to connect the connection material to the carpet backing layer with high strength. In this case too, however, heat can be supplied to either the sections A or B and / or the rollers 19, if this is desired.

FIG. 10 shows an embodiment of a carpet construction 21 in which the carpet part AA does not have a second carpet backing layer has, as was the case in FIG. The connecting material 25 of the connecting material section BB is applied directly to the first or primary carpet backing layer 23 in which the pile 22 passes through a latex coating is anchored. The spaced apart frame members 26 and the ribs 27 of the connecting material 25 and the protective separating layer 31 act in the same way as those based on FIGS. 1 ″ to 6 described. Arrangement.

130061/0336

When using the embodiment of the connecting material V-carpet construction (independent whether they are in the form of carpet tiles or in the form of wide strips and with or without a second carpet backing layer 4), the release protective layer 11 is removed to form the adhesive-coated bonding material layer 5 expose. The lower surface of the connecting material is placed on the floor 10. The arrow on the protective separating layer shows the installer the weaving direction of the pile 2 so that the carpet in can be laid in the right way. If necessary, adjust the position of the carpet when laying it correct, so allows the dry glue or pressure sensitive adhesive 9 on the lower surface of the connecting material 5 that the carpet can easily be lifted off and reapplied.

If the carpet has been lying for a period of time and it is desired to lift it off the floor, so be it is only necessary to lift the edge of the one-piece construction and the connecting material 5 after to pull up. The connecting material 5 takes up the entire one-piece connecting material / carpet construction with. Because the connecting material 5 on the carpet backing layer 4 (or 23 - in the embodiment according to FIG 10) is attached in a substantially permanent manner, the lifting of the connecting material 5 causes a lifting of the entire connecting material together with the carpet section supported by these, so that the entire Connection material / carpet construction is lifted off.

Because the only points of attachment to a floor 10 are formed by the dry adhesive or pressure-sensitive adhesive 9 on the connecting material 5, the floor 10 remains in place

Lifting off the connecting material-Z carpet construction undamaged, and furthermore, since the connecting material 5 is an integral part, the carpet backing layer remains 4 of the carpet is not attached to the floor and will not be torn and the like.

The dry adhesive or pressure sensitive adhesive laying system described above can be used for laying all types of carpets as well as wooden tiles, ceramic tiles and resilient flooring materials are used. Carpets can be laid with a back layer through Sponge rubber, foam rubber, vinyl (foam or solid) polyethylene, jute or through a clear latex compound layer is formed. The carpet products can take the form of carpet tiles, carpeting, bath mats and wide loom grades that can be woven, knitted, knotted, fused or sewn. The laying method according to the invention and the connecting material can also be applied to elastic coverings, such as e.g. Vinyl asbestos pleating and vinyl sheet material, etc. applied will. Wooden floor coverings, in particular wooden tiles or parquet sections, and ceramic tiles can also be used be used.

In all cases there are advantages in terms of easy and economical laying and ease of installation Removal of laid materials from the floor or other work surface without the need for special equipment are required and without residues of the carpet, the resilient floor covering or the adhesive system on the Floor remain. In other words, this means that according to the invention a self-adhesive component with its own integral part is created instead of the usual Glue or other laying systems can be used that were normally required heretofore.

The connecting material-Z carpet construction according to the invention withstands the heaviest loads including heavy traffic, of those equipped with wheels Vehicles, wheelchairs and combinations of these loads without losing the possibility of the connection material / carpet construction peeled cleanly from plywood-cement and vinyl floor coverings, to which this construction was applied. The connection material / carpet construction remains intact even when exposed to extremely high or low temperatures, and it can even withstand moisture, the connection being re-established on drying (if it has failed). Normal maintenance procedures, such as vacuum cleaning, wet cleaning and the like have no adverse effects.

In addition to the usual flat floor surfaces, the connecting material system described above can also be used in a variety of other applications, such as wallcovering, fastening of Pictures, tapestries, templates, ceiling tiles and the like. Another essential application arises in the area of the interior trim of vehicles, where carpets, door panels, ceiling panels and even truck linings made of stretch fabrics can be molded and attached at the same time. Another possible application is in the area of upholstery, where lighter weight fabrics and unstable to scale Tissue attached to and easily removed from cushioning systems.
