The invention is directed to improvements in synthetic "grass" coatings. The present invention, in particular, aimed at improving synthetic "grass" surfaces for sports facilities. The present invention also aims to create the th and device for carrying out the method. The present invention is further directed to the improvement of synthetic "grass" surfaces for sports facilities, containing guidelines for games, formed in their upper surface, and a method of manufacturing a lined surface.

Synthetic "grass" coatings for sports facilities are well known. They are used to replace natural turf, not sufficiently resistant to wear and require large expenditures for their maintenance in proper condition. In addition, natural turf is not enough to grow well in partially or fully enclosed sports facilities. Synthetic "grass" coating is much more resistant to wear than natural turf, do not require such high cost of care and can be used in closed structures. Some synthetic "grass" coatings contain a series of strips or ribbons of synthetic material upward from the base of the Mat, and the gaps between the ribbons on the Mat filled dispersed material. Ribbons of synthetic material are usually somewhat higher above the layer of dispersed material and represent the "stems" of grass. The bottom the name of the Haas Jr., and in U.S. patent 4 389 435, 1983, issued in the name of Haas Jr., but may contain other materials, or a mixture of sand and other materials, as shown as example in U.S. patent 4 337 283, 1982, issued in the name of Haas Jr. The dispersed material provides elasticity synthetic "grass" coatings, these coatings are often placed on an elastic substrate, providing even more flexibility to the coating.

Known sand filled synthetic "grass" coatings for sports facilities have a number of disadvantages. Coverage usually become stiff after prolonged use due to the fact that the sand between the rows of ribbons compacted. The seal is at least partly due to the fact that the rows of ribbons are located very close to each other and the sand cannot significantly be distributed to the parties in the process of use. The seal is also partly because closely spaced rows of ribbons pick up the scraps, worn and torn ribbons in the sand even when the dispersed material contains rounded sand particles. With the increase in the seal coating is becoming more rigid and less elastic. The coating worse performs its functions and pangaud progie substrate, if they are used, are gradually destroyed, becoming denser. Removing and replacing the compact dispersed material or even loosening it difficult because of the small distances between the rows of ribbons. Removal and replacement of compacted dispersed material or even to loosen it may require expensive equipment and this leads to increased maintenance costs of such coatings.

Another disadvantage of the known synthetic "grass" surfaces for sports facilities is the issue of drainage (moisture removal). Leakage of water through the coating has always been small. Ribbons are usually attached to the Mat by firmware through the Mat, followed by the floor Mat on the reverse side an adhesive layer for attaching the ends of the ribbons to the Mat. The adhesive layer is not porous. To give the desired porosity of the Mat coated is subjected to puncturing to form holes. However, the dispersed material often falls into these holes, clogging them and thus reducing the drainage quality of the coating. Leak dispersed material in through holes also requires its replacement with the top side of the Mat, causing additional maintenance costs of coverage. The sealing surface is also prapatti. When the floor is filled rounded sand particles (rather rounded than angular, as it is believed that the rounded particles are less compacted and cause less friction), the floor may be too slippery, especially when ribbons only slightly greater than the thickness of the layer of dispersed material. In addition, closely spaced thin ribbons can firmly grab the spiked footwear, if they penetrate between them, and do not break as easily as grass, thus making the release of more complex spikes and turning the game on such surfaces more complex and dangerous than playing on natural grass. If the spikes shoes of the player is not released easily, it can damage the leg (from the hip to the foot, ankle or knee. It was also found that if the spikes shoes athlete penetrate into the coating in the weld area, the probability that the shoes will not be released or will not be able to turn significantly more.

Known synthetic cover with tightly spaced rows of ribbons also contribute to the increase in the speed of rotation of the ball compared to how the ball rotates on natural grass. Tightly spaced ribbons create a nearly continuous surface with low resistance, good discharge performance the second substrate, the balls bounce more on this turf than on grass, significantly changing the nature of the game. Surface with low friction also makes it more slippery for tennis players.

Known coatings have other disadvantages. Usually used ribbons are very narrow and they can bend, creating the appearance, not similar to the grass. Narrow ribbons also easier erased, which are formed fragments, which can increase the density of coverage. The dense arrangement of the rows of ribbons also leads to skin damage players falling or postalservice on the floor.

Known synthetic coating containing elastic frame element and parallel rows of synthetic ribbons, simulating grass, upward from the frame element (Patent Canada 2095158). However, this technical solution also has all the above-mentioned disadvantages of other devices of the prior art.

The aim of the present invention is to provide an improved synthetic "grass" coatings for sports facilities, which are more resilient and retains more elasticity for a longer period of time than known sentationsteknik "herbal" surfaces for sports facilities, with improved drainage properties and superior playing qualities.

Another objective of the present invention is to provide improved synthetic slot coating, less costly to manufacture, laying and especially in the service.

Another objective of the present invention is to provide improved synthetic games coatings with greater resistance to wear, which are more easily marking of lines and greater ease of stitching.

Another objective of the present invention is to provide a manufacturing method of a variant of implementation of the present invention, different superior drainage properties, and device for implementing this method.

In accordance with the present invention it was found that improved synthetic "grass" coating can be produced by using relatively far apart rows of ribbons. More distant rows of ribbons reduce seal filler compared to a seal for a more dense arrangement of the rows, thus prolonging the service life of the coating while maintaining its elasticity. Reduced compaction and abrasion ribbons, the extension of service coverage and to minimize the formation of scraps of ribbons, which affect the sealing and drainage quality. Remoteness series also promotes better penetration of the spikes shoes and more easily release them, thereby improving game quality and reducing the risk of injury for athletes. Remoteness of rows could also contribute to the balls on the floor revolved more similarly to how they rotate on natural grass, thus improving the game quality. Remoteness series also enhances the loosening of the dispersed material, if it starts to get thicker, and easier cleaning and replacement. Remoteness series also helps to reduce skin damage players in contact with the surface. Remoteness series could facilitate crosslinking of the coating.

Thus, in accordance with the first aspect of the present invention the above objectives are achieved through synthetic coatings containing elastic frame element, parallel rows of synthetic ribbons, simulating grass, upward from the frame element, and the ranks of flax the th element, at least twice the length of the step between the rows of ribbons, the coating includes layers of dispersed material located on the frame element, support ribbons essentially in a vertical position relative to the frame element.

It is advisable that the length of the ribbons upward from the frame element, was 19,05-127,0 mm

Preferably, the layer of dispersed material has a thickness comprising at least 2/3 the length of the ribbons.

Preferably, the ribbons were on to 6.35-25.4 mm) above the layer of dispersed material.

It is possible that the ribbon had a width of about 12.7 mm

It is expedient to frame the item was a single layer of fabric or non-woven needle-punched material.

Preferably, the frame element was a two-layer fabric or non-woven needle-punched material.

It is desirable that the frame element consisted of a three-layer fabric or non-woven needle-punched material.

It is possible to frame element contains one or more layers of material, and at least one of the layers was the material processed by hypoproteinemia to create hairiness on its surface.

CE is hypoproteinemia to create hairiness on its surface.

It is preferable that the coating contained a strip of covering material on the wrong side frame element applied on each row of ribbons to secure the ribbons in the frame element and the frame element is porous and is not closed coating material between the bands.

In accordance with another embodiment of the present invention improved synthetic "grass" floor is designed in such a way that it had improved drainage quality fashion and illustration attach ribbons. In accordance with the present invention, the rows of ribbons attached by means of strips of adhesive (coating) material placed on the wrong side of the Mat. Strips of adhesive material impose with certain intervals from one another and leave uncovered areas of the Mat. Because the Mat in this embodiment, porous, open areas provide excellent water drainage. Forming a coating with a relatively large distance between the rows of ribbons, you can place a strip of adhesive material, leaving between them a relatively wide porous areas. The present invention is also directed to a device for just the t due to the use of, at least one of frame layers of needle-punched material containing fleecy fibers on one or both of its surfaces. Fleecy fibers improve drainage quality frame layer and, consequently, coverage, because the tips of the fleecy fibers away moisture.

Thus, in accordance with the second aspect of the present invention the above objectives are achieved through synthetic coatings containing elastic porous frame element, parallel rows of synthetic ribbons, simulating grass, upward from the frame element, the ranks of the coating material on the wrong side frame element, which is covered with rows of ribbons, with one row of covering material covers one row of ribbons to secure the ribbons in the frame element, the ranks of the coating material are located at a distance from each other to create a uncovered narrow zones of frame element to improve the drainage qualities.

It is desirable that the coating contained a layer of dispersed material on the upper surface of the frame element to maintain the ribbons in an upward position.

It is useful to disperse the material contained smini or non-woven needle-punched material at least one of which was needle-punched material.

In the present invention using ribbons, which are significantly longer than those used up to the present time. In the greater length of the ribbons, you can get thicker layer intended for the use of dispersed material, which may allow to eliminate the need for elastic substrate and to make the process of paving a more simple and cheap. Use a thicker layer of dispersed material or filler promotes better drainage due to the higher water pressure created by the water on the synthetic "grass".

The longer ribbons can also contribute to the formation of a thicker layer of the tape material on the surface of the filler for some sports surfaces, creating a more realistic, more like natural grass floor, coupled with the greater distance of the rows of ribbons also helps as better penetration of the spikes shoes athlete at floor (for clutch), and their best release. Spikes shoes the player can shift the ribbon and the material of the filler in order to provide easier their release.

Also the La. The filler preferably contains a mixture of quartz sand and rubber particles obtained by grinding the rubber in frozen form. Ground frozen rubber particles are much lighter than the ground in unfrozen form rubber particles, and allowing more rapid removal of moisture. The ratio of sand to the number of rubber particles can be changed depending on the final destination covering: the more elastic the required coverage, the greater use of rubber. Ground frozen rubber particles less angular than unfrozen ground up in the form of rubber particles, and have less tendency to allow connection of water and microscopic air bubbles, which carries water to these particles. Thus, there is less tendency of the rubber particles to float up when the floor is flooded with water, which could lead to loss of material and change the playing qualities of the coating.

Thus, in accordance with a third aspect of the present invention the above objectives are achieved through synthetic coatings containing elastic frame element, the parallel rows of the e layer contains dispersed material, located on the frame element, support ribbons in directed essentially upward position relative to the frame element, and the dispersed material contains a mixture of ground frozen rubber and sand.

It is advisable that at least part of the dispersed material contained particles ranging in size from 0,59-1,2 mm

Preferably, the ground frozen rubber was present in the form of rubber crumb.

It is desirable that the layer has a thickness equal to at least 2/3 the length of the ribbons from the frame element to their free ends.

In accordance with the fourth aspect of the present invention the above objectives are achieved through synthetic coatings containing elastic frame element, parallel rows of synthetic ribbons, simulating grass, upward from the frame element, the coating includes a layer of dispersed material located on the frame element, support ribbons essentially in a vertical position relative to the frame element, and ribbons are mixed and contain more rigid ribbons and softer ribbons to achieve the specified structure of the field.

Predpochtitel structure of the playing field.

It is advisable that the ratio is more rigid and softer ribbons was 1:1.

It is desirable that more rigid and softer ribbons interspersed.

It is possible to pile tufts contained areas with a more rigid and softer ribbons.

Preferably more rigid ribbons had a linear density 11000 denier and a thickness of 100 μm, and more soft ribbons had a linear density of at least 5600 to 10,000 denier denier and a thickness of 80 μm.

The coating in accordance with the present invention is also provided with means for forming lines, and lines are used for marking coatings in accordance with the game plan to spend. An example of such yard lines are the lines used in the game of football, which cross the field at regular intervals. These lines are usually applied to the surface of the field with chalk or a similar marking material. In accordance with the present invention, the coating can be equipped with permanent lines sewn in floor. Line sew in the same way as frame layers were combined with each other.

After a General description of the nature of the invention will be made with reference to the accompanying drawings, showing tolone section cover, made in accordance with the present invention; Fig. 2 is a view similar to those shown in Fig.1, which shows the free ends of the ribbons located in a natural horizontal position; Fig.3 is a side view of a device for coating; Fig.4 is a cross section of 4 - 4 of Fig.3; Fig.5 is a top view of the device of Fig.6 is a detailed top view of Fig. 7 is a view in isometric frame element after applying to a cover; Fig. 8 is a front view with the digging of a seam in the floor, and the seam forms a marking line; Fig.9 is a view of the Assembly of the bead in Fig.8.

The best option is the implementation of the present invention
Synthetic "grass" floor 1, made in accordance with the present invention, as shown in Fig.1, contains a thin elastic frame element 3 parallel rows 5 strips or ribbons 7 upward from the frame element 3. A relatively thick layer 9 fills the dispersed material is placed on the frame element 3, support ribbons 7 in a relatively vertical position on the frame element 3.

Elastic frame element 3 can, as shown, to contain two lining layers 11, 13. The bottom layer 11 may be cloth or netnanny polypropylene material. Plastic strips or ribbons 7 stitch through the frame element 3, as shown in Fig.2, passing through both layers.

Although the frame element 3 has been shown as containing two layers, it may also be formed from one or more layers. One or more layers in the frame element 3 can be cloth, punctured hypoproteinemia in order to provide the best drainage quality, and the fabric may be relatively thick, if you use only one layer. At least one of the layers 11 of the frame element 3 can be bonded hypoproteinemia with fleecy synthetic fibres 15, as shown in Fig. 2, for insertion means for removal of moisture through the layer. Fleecy fibers further improve the drainage quality of the coating.

Ribbon 7 is made from an appropriate synthetic plastic material, which ekstragiruyut in the form of a strip of relatively great width and thickness. The preferred plastic material is polyethylene, which is soft and has good resistance to abrasion. However, the polypropylene can also be used for the manufacture of ribbons. The strips can have a width of 6.35-25.4 mm, but prepost and fix the flashing frame element 3 parallel rows of 5. The density of the pile tufts in a row is 2-8 on the length of 25.4 mm, but preferably it is 4 pile beam on the length of 25.4 mm Strip mechanically fibrillary or split to ribbons with a width of approximately 3,175 mm

Fibrillation, which is produced mechanically at the time of manufacture of the strip, allows you to get a ribbon, similar to the mesh for the hair, i.e., resulting from this process, the fibers are interconnected.

The distance between the rows of ribbons depends on the intended activity of the players on the field. For example, the spikes on sports shoes for various sports are on average increments, constituting approximately 19,05 mm Studs on football boots can be wider than a baseball spikes. The step between the ribbons depends on the type of sports games, which is expected to occur on the field, and is derived from a step between spiked sports shoes players. Similarly, in sports such as horse races, as you can imagine, requires a much greater distance between rows to accommodate a wider hooves of horses. Thus, it is possible to imagine that the race step between the rows should be to 57.15 mm proportionally with the other 12.7 mm, because the wider the ribbon is not twisted as easily as thinner ribbons, and more resistant to wear and abrasion. Wider ribbon 7 is also more dim the surface of the dispersed material, when they Lodge, holding the filling material, as shown in Fig.2. At least the free ends of the ribbons 7, located on top of the layer 9 of dispersed material, fibrillated to ensure the appearance of more dense pile. If laid synthetic "grass" floor and covered the filler, the ends of the ribbons can be even more fibrillated by use of wire brushes or other mechanical fibrillary funds.

It is also assumed mix of ribbons of different thicknesses. For example, depending on the type of the field, i.e. the field where the ball would be spinning much slower than the other, can be mixed more rigid and less rigid ribbons. More rigid ribbons as would have greater memory and thus return the ribbon to the original standing position, relatively speaking. Examples of such mixtures can be thick ribbons linear density 1210 Tex at a thickness of 100-120 microns. Softer ribbons can be linear PLO is Elena specific requirements to the playing field. The ratio of hard and soft ribbons can be 1: 1. These hard and soft ribbons can be arranged in an alternating or can be in a single pile beam.

In accordance with the present invention, the series 5 ribbons 7 are arranged with a pitch "a", which is 15,875-57,15 mm Step between rows depends on the final destination of the coating, and a smaller step used in coatings intended for the less physically active sports, such as Golf on the grass, and the bigger the step used in coatings intended for more active sports, such as horse races.

Relatively larger step between the rows of ribbons gives several advantages to the floor. With a larger step reduces the tendency of the coating to the seal. If the tendency of the seal is reduced, drainage quality improved. With a larger step also reduces the amount of material required for the manufacture of ribbons. With a larger step improves game quality of the coating. The athlete who plays on this floor, has great grip, as the spikes shoes player easily penetrate into the dispersed material between the rows of ribbons. At the same time, the spikes easier released, because IMessage also easier to loosen, clear and even replace the dispersed material. Between the rows there is more space for the introduction of material air nozzle to gently loosen it slightly, to raise its level. Loosened and lifted the material can be collected, cleaned from dirt and pieces and returned to the frame element. The service life is increased and, thus, the replacement costs are reduced. With a larger step also easier to sew joined segments coating without creating thickened joints, because there is more space for the seam.

The length of the ribbons is also an important feature of the present invention. The length "L" of the ribbons 7, i.e. the distance from the frame element 3 until the free end 17 of at least twice the distance "A" between rows 5 ribbons and preferably three to six times larger than the distance "A". The length "L" of the ribbons can be 19,05-127,0 mm, and a shorter ribbons used in coatings in smaller increments between the rows and the longer ribbons used in coatings with a large pitch between rows. The relatively long ribbons in comparison with those used in known to date technical solutions that allow you to use a thicker layer Napoli eliminates the cost of purchasing the lining of the Mat and for its installation. A thicker layer of filler 9 improves drainage qualities due to the formation of a higher water level and thus create a higher water pressure on the upper surface of the coating. The use of a longer ribbons may also enable you to get a longer free ends of the ribbons over the layer of filler, even if the filler layer will be thicker, and loose ribbons provide for greater protection of players from sand and other particulate materials when they fall on the floor and reduces the risk of damage to the skin. Ribbons may protrude from the surface of the layer of filler somewhere to 6.35 to 25.4 mm, the thickness of the layer of filler may be 25,4-101,6 mm depending on the final destination of the coating. The filler layer usually has a thickness "T", comprising about 2/3 of the length "L" of the ribbons.

Layer 9 dispersed material preferably comprises a mixture of hard sand, such as quartz, and ground freezing rubber crumb. Ground freezing crumb rubber is preferred because the particles are more rounded, which reduces to a minimum the friction and also reduces the degree of compaction. Less angular rubber particles are easier to thread if the surface is washed so as microscopic air bubbles are not easily stick to rounded particles. The size of the particles can be in the range of 0.16 was 2.76 mm, but preferably in the range of 0.59-1.2 mm, for coatings intended for such sport where the friction players in contact with the floor, is a significant factor, and 0.16-1.2 mm, where it is not essential. Quartz sand can be replaced with assorted small pebbles, hard and heavy plastic granules or other solid sand. Ground freezing crumb rubber can be replaced by other elastic materials, such as cork, steren, ethylene-propylene rubber, neoprene, or other similar materials, if the particle shape matches the shape of the ground during freezing of rubber. In some cases, part or all of an elastic material may be replaced by other materials that perform specific functions. An example would be the use of perlite, which can replace the elastic material to reduce compaction and the ability to absorb moisture.

The ratio of sand and elastic material in the mixture can be changed depending on the final destination of the coating. More Chernogo material can be divided into sublayers, of which the underlayer 17 is located next to the frame element 3, as shown in Fig.2, and contains particles of a smaller size, and the upper sublayer 19 contains particles larger for initiating good drainage. Particles in the lower sublayer 17 may be composed mainly of sand with sizes in the range of 1.57 was 2.76 mm Upper sublayer 19 may contain sand particles are larger in size, mixed with particles of rubber. Use mainly or only sand in the lower sublayer allows to reduce the cost of coverage.

The cover 1 is made by attaching ribbons 7 flashing them through the frame element 3 in the form of series 5, located increments 15,875-63.5 mm, and in each row have 2-8 ribbons 25.4 mm After flashing ribbons 7 on the wrong side frame element 3 may be covered with a coating for bonding the strips to the frame element. The coating can be applied to the whole frame element.

Preferably, however, in one embodiment of the present invention, in which use porous frame element, only part of the frame element to apply coating to provide better drainage qualities and to reduce the cost of coverage. In accordance with the laws of the Sabbath. Orono down through any standard machine for coating carpets.

Machine 31 to the coating, as shown schematically in Fig.3, 4, 5 and 6, includes a support plate 33 to maintain stitched frame element 3 of the cover 1 when it passed through the machine. There is a means (not shown) to move the frame element 3 along the support plate 33 from one side to the opposite, as shown by the arrow 34 in Fig.3. When the movement of the element 3 along the support table 33 it passes under the comb-shaped device containing a series of parallel slats 37 resting on the inside surface of the frame element 3 and placed against the support plate 33. The bars 37 can be adjusted according to the distance (pitch) between them, and their position is adjusted, with each bar between each pair of adjacent rows of 5 ribbons in the frame element 3. The rod 39 is located above the slats 37 closer to the front of the bars 37, than to their rear. Means for applying 40 is intended to supply coating material "M" to granatabolu device 35, across its width just before the rod 39. As you move the element 3 to the right, as shown in Fig.3, under the device 35, covering the material "M" is carried away together with the element 3 in the direction of the squeegee 39, where the coating material raspredelyat series 5 ribbons, and the ends of the ribbons in these series cover covering the material "M" in order to glue the ribbon 7 to the frame element 3. The strap 37 protect against ingress of coating material "M" on narrow sections 43 of the frame element 3 located next to the rows of ribbons 5. When the frame element 3 is removed from under the straps 37, on his wrong side remain strips 45 covering of material "M" closing ranks 5 ribbons, but adjacent areas 43 of the frame element 3 remains open due to the straps that provides a very high porosity of the coating, which contributes to a very easy flow of water. The amount of coating material laid by a device for applying significantly less than is required for deposition on the entire surface of the frame element, and thus achieve additional savings of materials, making the floor more cheap.

Although there is described one form of coating in the form of stripes on rows of ribbons, the coating can be applied by other means. For example, adjacent nozzles can apply a thin coating lines at the rows of ribbons and using a squeegee, you can align the lines of covering material on the wrong side of the Mat, at the same time leaving otnositelnoy. Can be used for shafts of different diameter for coating.

In accordance with another embodiment of the present invention the line for marking the playing space can be made in the floor by connecting the adjacent edges of the sections covering special seam. As shown in Fig.8, stitched cloth 51 is placed under join, but distant from each other, the edges 53, 55 of the adjacent sections 57, 59 coatings, which require to connect. Stitched canvas 51 contains rows 61 stitched ribbons 63 in its middle section 65, but does not contain ribbons in sections 67, 69 width. The Central section 65 is located between the edges 53, 55 of the segments of the cover 57, 59, and stitched ribbon 63 in the Central section 65 may be of a different color and/or different heights unlike ribbons 7' in sections cover 57, 59, to form line 71 for marking the field of play. Sections 67, 69 width stitched canvas 51 can be processed by hypoproteinemia to obtain fleecy material. Glue "And" put on the front side sections 67, 69 width for bonding thereto imposed lapped sections 57, 59. Fleecy material improves the connection stitched canvas 51 with sections covering 57, 59 when gluing. Stitched canvas 51 Molino under the side sections 67, 69 also. This prevents from penetration glue "And" used to perform the stitching through the fabric 51 and, probably, from bonding to the substrate. When the canvas 51 attached to the sections of the cover 57, 59, as shown in Fig.9, and connects them with each other, ribbons 63 because of the differences from the ribbons 7' in sections cover 57, 59, determines's line 71.

In another embodiment, the present invention can be used floor with long ribbons, the length of which is at least 114.3 mm, and a layer of dispersed material may have a thickness equal to the length of the ribbons. This coating can be used as a surface for germination. The dispersed material may contain substances that promote the growth of plants, such as substances that retain moisture for plants, and substances that allow to develop the root system of plants. Improving substances can form one or more sublayers in layer of dispersed materials. In some cases, improving substances may have a specific gravity less than the specific weight of water, and the location of this substance in the lower sublayer under the top layer ensures that it is in place and it does not take away water. This pokrytiya dispersed material. The porosity of the frame material can be created to preserve moisture in the material to promote plant growth. Ribbons can minimize the amount of dispersed material, which may be gone with the wind in regions with windy weather.

Sports field, which use high pile of ribbons, a thick layer of dispersed material, including ground frozen rubber, can be used to support the growth of natural grass, the roots of which penetrate into the dispersed material. Post

FIELD: manufacture of plant covers used for beautification of streets, squares, construction of sportive grounds, as well as for landscape designing.

SUBSTANCE: method involves spraying organic adhesive onto fine-mesh basalt net by means of specially designed equipment for filling meshes to thereby create strong carrier base. Net is perfectly ecologically safe and allows seeds to be uniformly sown over the entire area of lawn. Adhesive used for providing lawn is functioning as nutritive compound for seeds and is used simultaneously for protecting seeds from external influence of moisture and air during prolonged periods. After drying in first drying chamber, mixture of lawn grass seeds is sown onto carrier base through dosing hopper, followed by applying onto given mixture of organic adhesive and drying in second drying chamber. After discharge from drying chamber, ready dry lawn is cut into parts of various lengths, wound into roll and hermetically packed in polyethylene film for further storage and transportation. Lawn is placed on site by unwinding roll onto preliminarily prepared ground and spilling nutrient mixture thereon, followed by heavy irrigation to provide for sprouts emergence. Nutrient mixture and lawn grass seed mixture compositions are worked out depending on climatic zone and composition of parent ground on which lawn is to be provided.

EFFECT: increased efficiency by providing uniform sowing of seeds over the entire lawn area, and damage-free transportation and handling of grown lawn.
