The scope of the invention

The invention concerns a method of laying a carpet that has a lining with an exhaust loops through the device laying the hook - loop.

Prior art

Usually carpets, intended for laying wall-to-wall, glued to the concrete flooring (commercial systems) or stretched between spaced staggered rows of steel pins (as, for example, Roberts stacking "smooth edge").

In U.S. patent N 4822658 from 18 April 1989 proposed a new method of installation, according to which made the carpet with pad, essentially consisting of loops and stack it with the supplied hooks ribbon, sealed with Paul sensitive to davieebee, concerning the constancy of sizes with variable atmospheric conditions, in particular, this applies to carpets, which used synthetic nylon fiber.

These problems are the consequence of the fact that nylon, absorbing moisture, increases in weight by approximately 6% and extends approximately 30% of its size.

With carpets industrial production is due more problems, such as problems caused by such factors as, for example, the type of production process and material type (latex, polyurethane, and so on), which is used for flashing the pile of bundles of fibers via the primary lining. The main problem is that the stacker carpet in the process of laying it in place cannot anticipate the impact of the atmosphere, while it is not already too late. When the carpet is laid around the perimeter and the danger that it will stretch around the perimeter seems to be resolved, any tendency of the increase of the carpet will manifest as subtle folds and wrinkles. The increase of the carpet around the perimeter is often caused by humidity fluctuations occurring in the atmosphere. Such fluctuations are common in buildings that are not controlled by climate and temperature.

were the following operations: (a) the carpet was glued bottom along its bottom surface; (b) was performed correction nylon fiber by increasing the weight and stiffness of the Mat reinforced by fiberglass as a stabilizing factor; or (C) used a system of hook and loop for attaching a carpet over its entire bottom surface.

Intensive use of fiberglass can provide greater stability of the original dimensions of the carpet, but does not resolve the problem. In fact, in some cases, the amount of glass fiber is likely to exacerbate the occurrence of deformation, if the carpet does not have sufficient rigidity to withstand tensile strength. More importantly, the increased rigidity complicates the manipulation of the carpet, rolling, smoothing and cutting Mat. It may also be difficulty in ensuring consistency in the pattern of such rugs, as they are "drawn" very slightly or not at all amenable to manipulation if necessary, appropriate pattern.

Efforts were also attempted with varying degrees of success to smooth out irregularities of hand-sewn seams woolen carpets processing jute lining seam area with a small amount of hot water. Splashing hot water on jute is in this case when there are changes in humidity and dryness occurred deformation of the Mat and the appearance of irregularities especially near seams.

The basis of the invention the task is to create a method of laying a carpet, which would exclude the deformation of the Mat in the process of its operation in the presence of variable cycles of wet and dry environment.

This task is solved in that a method of laying a carpet that has a lining with an exhaust loops, comprising the following stages: (a) floor-mounted tape having upward-directed hooks, closed circuit coverage, in order to avoid untimely clutch hooks with carpet; (b) a free arrangement of carpet having a lining with an exhaust loops on top of the tape, according to the invention additionally comprises the following stages: (I) the application of water on the carpet to absorb water carpet fibers; (d) holding period, allowing the carpet to achieve essentially the maximum extension; (d) removing the coating from the tape for attaching the carpet to the floor essentially in its expanded condition.

Preferably after stage (d) carpet trim and fit them to the bathroom or to adjacent strips of carpet in its expanded condition.

It is advisable to stage (b) included free packing of multiple strips of carpet, overlapping, and furnish such strips together which you can use carpet, with nylon tufted cover.

In this case, the period of incubation required for the stage (g), it is advisable to select equal to at least two hours, and preferably equal to at least four hours.

Even more preferably, the period of incubation did not exceed six hours.

It is advisable water is applied by spraying or sprinkling on top of the carpet.

It is advisable water to put in the amount of not less than 3.5 l 80 m2.

In another aspect the problem is solved in that a method of laying a carpet that has a lining with an exhaust loops, comprising the following stages: (a) floor-mounted tape having upward-directed hooks closed with a removable cover, in order to avoid untimely clutch hooks with carpet; (b) a free arrangement of carpet having a lining with an exhaust loops on top of the tape; according to the invention additionally comprises the following stages: (I) removing at least some portion of the cover tape for attaching the carpet to the floor; (g) application of water on the carpet to absorb water carpet; (d) holding period, allowing the carpet to achieve essentially the maximum ID is controlled by the expansion of the Mat; (g) re-mount carpet to the tape in its essentially the expanded state.

It is advisable water is applied by spraying or sprinkling on top of the carpet.

It is advisable water to put in the amount of not less than 3.5 l 80 m2.

It is preferable that the period of incubation is for at least three hours and does not exceed six hours.

You can carpet be laid in strips, and tape set on the floor to align the bottom longitudinal edges of the strips of carpet.

It is reasonable that at least some of the longitudinal edges of the strips of carpet overlap and attach to the floor at the stage (C) in overlying relationship.

It is also desirable that the overlapping strips separated in stage (e) and then install it again in overlying relationship on stage (W), and the method includes the additional step (C), which creates a joint between the overlapping strips by cutting two strips along the overlap to obtain the corresponding seam and remove unused pieces of the edges.

In the third aspect the problem is solved in that a method of placing a nylon carpet having to connect the hooks, covered by a removable coating to prevent untimely clutch hooks with carpet; (b) a free arrangement of strips of carpet that has a lining with an exhaust loops on top of the tape so that at least some of the strip overlapping the adjacent strip along the longitudinal edges of the band, according to the invention additionally comprises the following stages: (I) removing at least some portion of the cover tape for attaching strips of carpet to the floor essentially along their longitudinal edges; (d) spraying water on the carpet in the amount of at least 3.5 l 80 m2; (d) the holding period of at least four hours and not more than six hours, allowing the carpet to achieve essentially the maximum extension; (e) separating the strips of carpet tape at least in some areas to relieve pressure and strain created by the expansion of the Mat; (g) re-fastening strips of carpet on the merits in the expanded state to the tape with an overlap of adjacent strips; (C) cutting a longitudinal edges of both strips of carpet along the overlap to get a smooth joint and remove scraps.

And, finally, in the fourth aspect the problem is solved in that way ukladki is within the fiber, which expands in wet form, further includes the following stages: (a) wetting the carpet; (b) waiting for its extension; (C) laying it on the floor in still an expanded condition for its fastening.

The invention is further explained in the description of specific variants of its implementation and the accompanying drawings, on which:

Fig. 1 depicts stacker carpet, obrushivshego carpet;

Fig. 2 is a view in section, showing two overlapping strips of carpet after wetting to relieve strain extension;

Fig. 3 is a view in section, showing two overlapping strips of carpet after removing the deformation of the expansion and before the final cutting of the carpet.

The essence of the method of laying a carpet according to the invention is that first the carpet is subjected to acclimatization on the possible extension under the influence of humidity by adding water on the carpet and then fixed to the floor in its expanded condition.

The amount of moisture needed to expand, for example, nylon, and the time required to ensure that the carpet has reached its maximum expansion, such that it is possible to apply the water on the carpet during installation, without causing a significant delay when laying carpet. To the carpet, and without complying with this operation, the carpet has a tendency to shrink to its original state. This allows you to retain the shape of the carpet even after drying. In addition, it was found that the carpet is no longer expanding and is not deformed even when subsequent cycles of wet and dry.

In Fig. 1 shows a carpet 1, freely laid on located on the floor of the ribbon 3. The first tape has a coating 5, which prevents the coupling loops on the bottom of the carpet 1 with hooks on tape 3 (best seen in Fig. 2) up until the coating 5 is not removed from the tape 3. In Fig. 1 stacker 7 rug has a simple canister 9 with water under pressure from the hose 11 and a spray nozzle 13. Such cans with water usually have a hand pump 15 from the top of the canister and easily fits one gallon ( ~ 4 l) of water. Stacker 7 just leads a spray nozzle 13 on the carpet in several passes, sufficient for the application of about one gallon of water per 100 square yards ( ~ 3.5-4 liters at 80 m2).

In Fig. 1, because the carpet is not secured to the strip 3, it will just increase in size after wetting, assuming that it is made of artificial or synthetic material that increases in size in the wet. Nylon is the most what is the absorption occurs in these carpets when spraying them with water from above during the period of time of about 4 hours.

Water also can be applied from the bottom of the carpet if the carpet does not have a waterproof lining) or directly on the floor as rolling carpet. Nylon fiber will easily absorb moisture.

An experiment was conducted using nylon carpet company Perles carpet, Montreal, Canada. This nylon was sent to the factory textile rubber end for securing the lining of elastomeric polyurethane and was then provided with a layer of woven lining with an exhaust loops.

The carpet was attached to the concrete floor around the perimeter using a tape with hooks, then moistened with water from the canister 9 (Fig. 1) while pressing on the pile finger stood out water.

Within hours there was a noticeable deformation of the carpet. Held on the perimeter of the carpet is deformed in one direction only. Folds continued to occur within 4 hours, during which the carpet has reached its maximum expansion or deformation. Folds remained in the carpet about two hours, and then began to fall.

Subsequent experiments showed that in most nylon carpets maximum expansion takes 4 hours. Further, if the carpet is mounted similarly on the edges of its perimeter, or not attached, the extension omanikega resistance. Thus, the strips of carpet extending generally occurs across the width of the strip, and not along its length.

In subsequent experiments, the carpet was attached to the floor, as described in the first example. After the maximum deformation after 4 hours, the carpet was removed from the tape to relieve the pressure created by the deformation, and then fastened to the ribbon. After drying, it did not leave the tape and remained in its domesticated state, even after repeated wetting and drying.

Further experiments with this acclimatized carpet on the humidity and temperature showed that the carpet is not deformed and does not move, even if he is 90% humidity for three days.

It should be understood that under normal conditions, the carpets are in controlled climatic conditions and humidity up to 90% within three days, indicate a problem in the air conditioning system.

The carpet is mostly in one direction (usually the width of the roll). Thus, it is possible to lay carpet tape to reflect this increase. If the carpet is attached to the floor after application, water can be seen immediately deformation and wrinkling, which indicates expansion. Fig is the number of strips) are placed on top of the tapes and coatings so, that seams meet on tape.

Since it is often necessary to alter only one seam to remove stress from expansion, for example, in a strip 23 of the carpet seam 27 may be completed between the strip 23 of the Mat and strip 25 of the carpet. Stacker usually leaves the seam slightly overlapped, that is, the seam through the following one, for example, between the strip 23 of the Mat and strip 21 of the carpet. It provides a place for overlap and create a smooth seam, even if the carpet is not enough increases after wetting.

Usually strips of carpet are attached at least to the tapes under longitudinal seams. However, the strip 21 of the carpet, for example, will be only partially attached to the tape 18, as shown, to provide overlap.

Fig. 2 shows the layout after the preliminary installation and after wetting with water the surface of the carpet. Water damage on the carpet (Fig. 1), forms folds 29 across the width of the Mat (Fig. 2). The carpet, as the length and width will be stretched across the width (respectively width of machine template), the line of least resistance. May increase in length, but in these experiments, no such data. However, this can be avoided by relaxing the tension of the carpet and re-fixing its ends, as Tr is edit, (a) wetted necessary strip of carpet, and (b) the band has reached its maximum extension. The stacker can then remove the pressure deformation, for example, in the band 21 and the belt 23 by removing the strip of carpet tape 18 and smoothing them to eliminate folds 29. Strips 21 and 23 thus overlap then on the tape 18 (Fig. 3) and the stacker can then cut the carpet along the top of the tape (item 31) to create a smooth seam. Extra pieces 33 and 35 are then removed and the result is a smooth seam.

This invention is applicable to any natural and artificial fibers used in carpets, which increases or expands when you add water. Nylon is the most common such synthetic fiber.
