description

Field of application of the invention

The invention relates to the field of artificial Gleitläehen, that is on flat pads or mats, for example made of plastic. These are mainly used to be able to practice winter sports independently of winter sports. Another application is the use as a sliding surface for conveying applications.

Background of the invention

Artificial sliding surfaces for driving on winter sports equipment have been known for several decades. There are a variety of systems with more or less good snowplough-like properties. These features include above all the leadership of the sports equipment, the Gieitverhalten, the absorption of shocks and the risk of injury of the coating. The systems are installed on the level for cross-country skiing or on slopes for use on alpine skis, snowboards, ski jumps, toboggans and tubes. The base on which the artificial sliding surface is placed can be made of natural soil, concrete, etc. or scaffolding components.

State of the art

Artificial Gleitfläehen consist for example of injection-molded plastic grid plates. On the approximately 2 cm wide webs of the grid equally high plastic pins are arranged, which should form the snow substitute function. For ski-jumping and tubing applications, mats of lasts with plastic rods attached thereto are known. Large-area mats made of tufted or woven pile fabric (GB 2 394 902) are also known. The pile thread consists of synthetic monofilament or foil yarns. [0004] Document FR 2 772 053 describes an artificial sliding surface based on a latticed knit fabric using monofilament yarns.

In document DE 2318415 A a cross-country track for the classical technique is presented. The tracks are laid individually on the ground. Each track has as a sliding surface on plastic plates, which are provided with scales to increase the leg friction between the stiction between ski and plastic plate. The leadership of the track is done by open at an angle upwards laterally mounted square sections. In the profiles grooves for fixing the shape of the plastic plates are introduced.

Document DE 102005062711A1 describes a sliding surface formed from knobs. The sliding surface is coated by fluoropolymers. In the wet test and the use of lubricants, a coefficient of friction of less than μ = 0.06 is achieved compared to the ski.

The document DE 288982A5 relates to artificial ski tracks especially for ski jumps. Described therein are special modules have the air outlet openings to create between ski and pad friction-reducing air cushion.

A base made of plastic with it in Gilter shape arranged knobs of ceramic material is described in DE 20211137 Ul. In the further development by WO 2008151748 AI, the surveys can be exchanged. In the nubs material and shape is varied.

The utility model DE 1871540 U describes a cross-country skiing track for training the classic. Technology. The track is formed from a plastic profile and has grooves on the sliding surface in the sliding direction. In all systems, the irrigation of the sliding surface or the treatment with lubricants causes friction. However, irrigation must be permanent, as these systems have no water storage function. [001 1] The disadvantage of known artificial sliding surfaces is that these systems are not sufficiently adapted to the requirements of the practice. What can be summarized in the following points:

- The frictional resistance is very high in all systems.

- The leadership property of sports equipment is insufficient.

- Due to design and material, most systems have a high to very high risk of injury.

- The installation of the systems is sometimes enormously expensive.

- For most of the system, permanent irrigation is necessary to achieve a suitable lubricating effect. The systems have no water storage function.

Summary of the Invention In view of the above drawbacks, the present invention therefore has the object of providing an artificial sliding surface which enables cost-effective manufacture and installation.

The object is achieved by the objects specified by the features in the independent claims. Advantageous embodiments are the subject of the dependent claims.

The textile runner sliding surface segment according to the invention or a textile runway essentially formed therefrom consists mainly of a fabric which forms the sliding surface, an intermediate layer and an underlying back coating. The artificial sliding surface is also referred to below as a textile slope due to the predominantly textile construction.

The fabric is a flat woven fabric which has warp threads and weft threads around asst and in a fabric direction floating and non-floating warp thread. Textile runner Gleitflächensegment of flat fabric, wherein the flat fabric comprises warp threads and weft and in a fabric direction floating and non-floating warp thread has. Furthermore, the warp threads can form a surface.

Furthermore, the warp threads can be made of a material or a mixture of materials, from the group: PE, PP, PBT, PET or PA. Furthermore, the material mixture or the material of the segment may be added slip additives.

Furthermore, the flat fabric of the segment of splice yarn, Moni Ii lamentgarn, monofilament, braid monofilament or monofilament can be constructed.

Furthermore, the flat fabric of the segment may comprise a back coating.

Furthermore, the back coating of the segment can be formed from at least one of: PVC, styrene-butadiene, PUR, latex, PES, PE, PP or hotmelt adhesive.

Furthermore, in the textile piste, the outer skin of the band elements are formed of film or nonwoven. Furthermore, in the textile piste the webs of pliable material or Kunststoßprofi! be attached to the textile slope.

The invention can also be used for transport purposes. For one thing, e.g. Goods can be slidably transported over the segments and, on the other hand, e.g. Conveyor belts are equipped with the invention, so that in a jam of the goods to be transported on the same band can slide without great frictional resistance among the goods.

DETAILED DESCRIPTION

Hereinafter, a detailed description of the invention will be given, which is described below with examples. First, general features will be given with reference to the drawings. A textile piste is essentially formed of segments having an artificial sliding surface (Figures 1, 1 and 2). The sliding surface continues to have a

Fabric (Figures 1, 2, 2) forming the sliding surface, an intermediate layer (Figures 1, 2, 3) and an underlying backing (Figures 1, 2, 4). An artificial sliding surface is also referred to below as a textile slope due to the predominantly textile construction.

The fabric is a flat weave having a canvas or body weave in a simple design. The fabric is preferably oriented so that the direction of travel (Fig. 1; 7) and

Orientierenimg the warp threads (Fig 1, 6) match. Especially in this arrangement The following constructions come to bear with regard to favorable snow piste-like properties.

The sliding surface (Figure 1; 2) of the fabric or segment is formed from warp threads (Figures 1, 6, 8) which float over 5 weft threads (Figures 1, 5), so that the floatations 1, 3 to 1.6cm. In a further embodiment, the sliding surface of the fabric is formed from over 2 to 20 weft threads floating warp threads, so that the float is 3mm to 10cm. The floating warp threads (Fig. 1, 6) lie in the weft direction (Fig. 1, 9) close to each other, so that a nearly closed surface (Fig. 1, 10) is formed and the warp threads form a large volume of wear.

In another embodiment, the floating warp threads are arranged in the weft direction at a certain distance (Fig. 1, 1 1), which is formed by one or many non-floating warp threads. As a result, raised areas extending in the weaving direction alternate with offset areas, and webs (FIGS. 1, 13) and grooves (FIGS. The raised areas, formed by floating warp threads, have a width of 0.5 cm to 5 cm. The remote areas without floating warp threads are 0.2 cm to 5 cm wide. The webs and grooves stabilize the sports equipment sliding on it and support its guidance in the direction of travel. When ski jumping, this tissue surface has a positive effect, especially when jumping on and off.

In an embodiment based on this fabric surface (Figure 1: 14), the floats (Figure 1; 15) are interrupted in the weaving direction by non-floats (Figures 1, 16). The areas without floatation (Figure 1, 16) have a length of 3cm to 10cm and alternate with floating. Areas (Figure 1, 15) with a length of 3cm to 12cm from. This surface texture makes it suitable for installations in the landing area and the ski jumping hill run-off area, as the fabric provides a safe and decongesting snowplough shelter.

The floating warp yarns serving as and as a sliding surface (Figures 1, 6) are formed from a particularly slippery material, preferably from PET or FBT. In further

Designs made of PE, PP, or PA as well as mixtures of these substances or with sliding additives, carbon black, graphite, molybdenum disulfide and silicone-added plastic. The preferred textile constructions of the warp yarns are splicing yarn (Figures 2, 17) and monofilament yarns or monofilament yarns (Figure 2, 18). In further embodiments, the warp threads are formed from ribbon yarn (Fig. 2; 19), from monofilament braids (Fig. 2; 20), or individually lying monofilaments (Fig. 2; 21). The thickness of these warp threads is at least 1 mm and at most 4 mm.

Alternatively, the floating warp threads are formed in the weft direction of different material and / or differ by the textile construction of the warp thread. Thus, smooth warp threads (Figures 2, 22), which carry 60% to 90% of the weight of the sports equipment, are arranged next to lubricant-storing and / or water-storing warp threads (Figure 2, 23) which lubricate the sliding surface of the sports equipment with lubricant or water wet. The smooth supporting warp yarns are preferably formed from splice yarns (Figure 2; 17) or monofilament yarns (Figures 2, 18). In another embodiment, the warps are formed of ribbon yarn (Figure 2; 1), monofilament braids (Figure 2; 20), or single monofilaments (Figures 2, 21). The preferred material is PET or PBT. Alternatively, the yarn is made of PE, PP, or PA or a mixture of these or with slip additives. Carbon black, graphite, molybdenum disulfide and silicone offset plastic formed. The adjacent warp yarns (Figures 2, 23) with water or lubricant storage function are preferably formed of multifilament yarn (Figures 2, 25) and alternatively of open cell foam (Figures 2, 26), nonwoven webs (Figure 2, 27) ) or multi-filament mesh.

Alternatively, the floating warp threads are formed from a core-shell construction (Figure 2, 24). Wherein the core consists of a lubricant-storing or water-storing construction of multifilament yarn (Fig. 2; 28), staples of yarn and in further embodiments of fleece (Fig. 2; 29), open-pore foam (Fig. 2; 30), multilayer braid or splice yarn can be formed. The sheath is preferably formed from monofilaments (Figure 2, 31) which helically encircle the core or from monofilaments which surround the core as a braid.

The artificial sliding surface is preferably by weaving, but can also be produced by tufting. A second layer (Fig. 1, 3) with water retention and / or damping and / or wear and / or stiffening function is arranged under the fabric.

The second layer (Figures 1, 3) is bonded to the overlying textile layer by gluing, riveting, welding, sewing or needling.

The second layer (Figures 1, 3) may comprise a plastic grid (Figures 1, 32).

The second layer (Fig. 1; 3) alternatively comprises a three-dimensional fiber-fabric covering (Fig. 1; 33) made of plastic.

The second layer (Figures 1, 3) may further comprise a plastic grid having a mat disposed therebetween or below or above.

The second layer may further comprise an open or closed cell (Figure 1, 34) foam. The second layer alternatively comprises a nonwoven (Fig. 1: 35).

The second layer further comprises alternatively a nubbed foil (Figure 1, 36).

On the underside of the sliding surface, a fixing, stabilizing and / or wear-protecting and / or providing good adhesion to the floor providing back coating (FIG. 2) can be attached to the second layer or, without the second layer I, 4). This layer can be made of styrene-butadiene, PVC. PURE.

Latex or a hot melt adhesive may be formed. The artificial sliding surface (Fig. 3; 1) can be provided on the edge (Fig. 3; 2) or concealed on the underside (Fig. 3; 3) with fastening straps. The connection of the tabs to the ground is done with, for example, pegs (Figures 3, 4), ground anchors (Figures 3, 5), Cable ties (Figures 3, 6) or similar connectors. The connectors are thereby inserted through loops formed on the tab or in the tab located holes (Fig. 3, 7). The holes can be reinforced by eyelets (Fig. 3; 8). If dowels are used in combination with pegs or ground anchors (Figures 3, 9, 10), attachment can be made directly through holes in the clothipiste because the pegs are in the dowel lie hidden and thus pose no risk of injury. It is also useful to attach the piste holes in the diameter of 2 to 10cm (Figure 3, 1 1) to cut into the mat, to close the opening from below with a strip of tissue or Textiipiste and sew it around the side, glued or welded ( Fig, 3, 12). In this strip, a hole with a diameter of 0.5 to 2 cm (Fig. 3; 13) is pushed and can be reinforced by an eyelet. Through the hole, a connector such as a peg or ground anchor is beaten or screwed into the ground. The connector does not protrude beyond the sliding coating in this arrangement and thus prevents injuries. The connector can also be covered with a strip of piste covering beyond (Figure 3, 14).

To the overlying, underlying or laterally adjoining connection of a plurality of artificial sliding surfaces (Fig. 4; 1 A. 2) are Velcro (Velcro) (Fig. 4; 3C, 4), pushbuttons (Fig. 4; B , 6) or a zipper (Fig. 4, C, 7) to the

Tabs or the tab (Figure 4, 5) or attached directly to the sliding surface.

The Textiipiste can be provided by embroidery, sewing, embossing, printing or weaving with patterns, coats of arms, logos, images and logos and signal and spur markers. To guide gliding sports equipment, such as toboggans or tubes and limitation of ski and toboggan runways, these are provided at the edge with bands (Figure 5, 1). The band is of a closed surface, eg PVC as a shell (Figure 5, 2) and a light and flexible or rigid forming core as a filler, eg foam (Figure 5; 3) or plastic (Figure 5; Straw (Fig. 5; 5) or plastic pipe (Fig. 5; 6) or sand formed so that it is foldable old (Fig. 5; 7) or rigid. j 0069] In addition, at the edge of the band or concealed at the bottom tabs can be attached for attachment. The connection of the tabs to the ground, for example, with pegs, ground anchors, cable ties or similar connectors. The connectors are thereby inserted through loops formed on the tab (Fig. 3; 2) or holes (Fig. 3; 7) located in the tab. The holes (Fig. 3; 7) can be reinforced by eyelets. To above, underlying or laterally adjacent connection with the downhill are also Velcro or Velcro (4, 3 and A), Druckknopf e (4, 6 and B) or a zipper (Fig 7 and C) are provided on the tabs (Figure 4; 5) or tab.

Alternatively, the band can also be made directly from the piste material (Figure 6; 1) by repacking the same and sewing, gluing or welding a tube-like cavity (Figure 6, 2). The cavity is filled by foam (Figure 6; 4), plastic, straw (Figure 6; 5), flexible tubing, rigid tube (Figure 6; 3), or bulk plastic or biomass. In a further embodiment, a tube (Fig. 6; 6) is introduced into the cavity, which is filled with filling material such as air, water (Fig. 6; 7), sand, etc. and conveyed via a drain valve (Figs ) can be emptied again. It makes sense a profiled modular tracking for gliding sports through the

Folding the piste material itself (Fig. 7; 1) or enclosing a filler material by additional profiles (Fig. 7; 2). The guide may be designed in such a way that it jumped cross-country skis, alpine skis or skis, each one individually (Fig. 7; 3), that is to say one ski each, or can lead genieinsam (Fig. 7; 4). The track can be made in a further embodiment for more than 1 pair of skis or for one or more snowboards. Furthermore, the track can lead to leadership. Tobogganing equipment can be used.

The tracking system is formed by fixing one or more folds or the trace profile of filling material having a height of 0.5 cm to 4 cm (FIG. 8; 1), through the piste material itself. The fixing of the fold / folds or the enclosure of the filling material takes place by gluing (Figure 8, Figure 2), welding (Figure 8, Figure 2), sewing (Figure 8, Figure 3),

Stapling (Figures 8, 4) or rivets (Figures 8, 5). In another embodiment, the fold / folds are held in shape by a support profile of plastic, metal, foam or wood. The fixation is done as already mentioned above by gluing, welding, sewing, tacking or riveting. In addition, an attached profile of an enclosing, moldable material such as fabric-reinforced PVC film or PE film, in combination with a filling material in a formed loop makes sense. The sole use of the material without filling is possible. In a further embodiment, the patch profile made of plastic, plastic recycling material, wood or KunststolTschaum can be produced. All variants of the fixation of the attached profile mentioned here can be carried out by gluing, welding, sewing, nailing, tacking or riveting.

In an alternative, the track-forming folds may be interrupted at regular and irregular intervals. The interruptions of the track-guiding folds are mainly used in the lift-off and lift-out area as well as in intermediate entrances and exits, or serve for safety, e.g. to the transverse position of the sports equipment.

The frontal fixation of the modules takes place on an attached tab with eyelets. Wherein connectors such. Ground anchors, pegs (Figure 3, 4) and cable ties are beaten through the eyelets into the ground. In a first embodiment, the tab along the front side at the bottom of the textile slope by gluing, sewing. Riveting or welding attached and flush with the front side. At the bottom of the mat and the top of the tab velcro or Velcro tape is attached to fix the textile piste in the flap.

In an alternative embodiment, the tab along the front side on the underside of the textile slope by gluing, sewing, riveting or welding is attached and protrudes with the eyelets on the front side. After attaching the slope, the visible part of the tab can be replaced by a. Covered piece of Gieitbelag. The sliding coating is preferably releasably connected by a Velcro connection with the tab or inextricably linked with adhesive A tracking for ski jumping, cross-country skiing, alpine skiing and snowboarding as well

Tobogganing is also achieved by covering a track profile made of wood, plastic, metal, soft foam, hard foam or Puren it. In this case, a base plate (Fig. 10, 1) may be included. On the base plate, strip-shaped profiles are attached to the left and right-hand guides of the sports equipment. The strips are semicircular in profile (Fig. 10; 2), rectangular, square or triangular (Fig. 10; 3) and connected to the grand plate by screwing, gluing, riveting or tacking. The base plate is flush with the profiles on the right and left sides. If the outer profiles 10 cm to 50 cm formed (Figure 9), they can be used at the same time as a landing surface for the pole tips in cross-country skiing. In one alternative, the base plate extends beyond the edge profiles 10 cm to 50 cm (Fig. 10; 11). Here too, the Grandplatte can be used at the same time as cross-country use for cross-country skiing. The track guide may also be formed of the textile track (FIGS. 11, 2) in one piece, for example, from a formed track-profiled plate (FIG. 11) of sheet steel or plastic. The execution of a piece of solid wood, plastic, hard foam, soft foam makes sense.

The textile sliding lining or at least one sliding surface segment is attached at least to the grand of the track or spans the entire or only a part of the surface. The strip profiles can be used at the same time for attachment of the sliding coating by clamping it laterally. The top surface for pole tips can also be covered with a particularly wear-resistant material. The possibility of Auswechseins the wear material and the textile sliding coating is ensured by adhesive, screw, clamp or Velcro connection.

example 1

Example 1 relates to the textile piste, which is used as toboggan and tubing track (Fig. 5, 1).

The textile piste is made up of 2 layers. The upper layer on which the tube or sled glides forms the sliding surface (FIGS. 1 and 2; made of flat fabric. The lower layer (Figures 1 and 2, 4) is a return coating.

The sliding surface of the fabric is formed from warp yarns floating over 5 weft threads (Fig. 1 and Fig. 2, 6), so that the float is 1.3 to 1.6 cm. The floating warp threads lie in the weft direction (Fig. 1, 9) close to each other, so that an almost closed surface (Fig. 1, 10) is formed and the warp threads form a large volume of wear. The fabric is oriented in the textile piste in such a way that the longitudinal orientation of the warp threads coincides with the direction of travel (FIG. 1, 7).

The floating warp yarns serving as a sliding surface are made of the particularly lubricious material polyester. The textile construction of the warp yarn is monofilament yarn or twine (Figures 2, 18). The strength of these warp threads is 2mm.

The weft threads (Figures 1 and 2, 5) are of 2.5mm. made of strong Polycstermul- tifilamentgarn.

For fixation and stabilization of the upper layer and as a wear and adhesion layer to the ground, a 2.1 mm thick return coating (FIGS. 1 and 2, 4) made of PVC is used.

Twenty pieces of the two-meter-wide and ten-meter-long modules of the textile runway are assembled one behind the other into a 200-meter toboggan and tubing track.

On the right and left side of the textile slope, bands for guiding the toboggan or tubes are arranged (Fig. 6; 1). For this purpose, the edges of the textile track are turned over, so that a tubular cavity (Fig. 6) forms on the right and left. These turns are fixed by sewing (Fig. 6; A; 3). The cavity is filled by flexible plastic tubes with a diameter of 125mm (Figure 6, A, 3). As a result, the bands have a circular profile shape. At the upper edge of the modules, a tab with a length of 5 cm is arranged over the entire width. In this tab there are five eyelet-reinforced holes. The outer holes are arranged 10cm from the right edge. The remaining holes are distributed over the tab at a distance of 45 cm. At the bottom are 10cm from the right and left edge, each 5 tabs with eyelets (Fig 3, 3 and 7). The lugs have a distance of 2m in the direction of travel. The fixation on the ground is done by pegs (Fig. 3; 4) or screws.

The modules are arranged overlapping in the direction of travel 20cm, so that the tabs eyelets and pegs or screws are covered at the top by the slope arranged above.

The modules weigh around 50kg and are similar to a carpet rolled up. This makes it very easy to transport the train. The assembly and disassembly can be realized quickly and easily due to the fixation with Lrdnägeln.

Example 2

Example 2 describes the textile piste, for use as ski jumping mat. The textile runway will be installed on the landing slope of ski jumps.

The sliding surface (Figures 1, 2) is formed by a web of floating and non-floating warp yarns (Figures 1, 12 and 13). The fabric is provided with a coating on the underside (Figures 1 and 2, 4).

The textile piste is installed so that the longitudinal orientation of the warp threads coincide with the direction of travel (Figure 1, 7).

The floats of the warp threads (Figures 1, 6) are made via 5 weft threads (Figures 1, 5) and is 1.3 cm to 1.6 cm. In the weft direction, regions with floating warp threads (FIGS. 1, 13) alternate in a ratio of 1: 1 with non-fasting warp threads (FIGS. This results in webs and grooves that stabilize the ski when jumping on and off. The webs have a width dimension of about 2cm and are made of 5 nebenei- formed lying, floating warp threads. The grooves with a width of about 2cm result from 8 non-floating warp thread.

The floating warp threads are formed from particularly smooth polyester monofilament yarn twine (Figures 2, 18) with a yarn thickness of 2.5 mm. The non-floating warp yarns are formed of polypropylene splice yarn (Figures 2, 17) having a yarn gauge of 2.5mm to 3mm.

The weft yarns (Figures 1 and 2, 5) are formed from 2.5 mm thick polyester multifilament yarn (Figure 2, 25).

The fabric is coated on the underside (Figures 1 and 2, 4) with a 1 mm thick PVC layer. The ski jumping mats with a width of 2m and a length of 5m. are put together to cover large slopes. For this purpose, the mats are laterally butted against each other and connected at the bottom by Velcro (Fig. 4, A). In the direction of travel, which coincides with the longitudinal orientation of the mats, the mats are arranged overlapping 20 cm.

At the upper edge of the modules five eyelets reinforced holes are arranged over the entire width. The outer holes are arranged 10cm from the right edge. The remaining holes are distributed over the tab at a distance of 45cm. At the top of the mats a flap with a length of 5cm is arranged over the entire width. In this tab there are five eyelet-reinforced holes. The outer holes are arranged 10cm from the right edge. The remaining holes are distributed over the tab at a distance of 45cm. At the bottom are 10cm from the right and left edge of each 5 tabs (Fig. 3, 3) with eyelets. The lugs have a distance of 2m in the direction of travel. The fixation on the ground is done by pegs (Fig. 3; 4) or screws.

The overlapping of the mats in the direction of travel covers the tabs located at the upper edge of the mats. Example 3

[00100] Example 3 relates to the textile ski slope for use as a sliding surface for the exit of ski jumps or also towed ski tows.

The sliding surface (Figures 1, 2) is defined by a fabric of floating (Figure 1;

15) and non-floating warp threads (Figures 1, 16 and 12). The fabric is provided on the underside with a coating (Figures 1 and 2, 4).

The textile piste is installed so that the Längsorientierang the warp with the direction of travel (Fig. 1; 7) match.

The floats of the warp threads (Figures 1, 6) are made via 5 weft threads (Figures 1, 5) and is 1.3 cm to 1.6 cm. In the weft direction (FIGS. 1, 9), regions with floating warp threads (FIGS. 1, 14) alternate with non-floating warp threads in a ratio of 1: 1 (FIGS. The flotation (Fig. 1, 15) is also interrupted in the direction of travel in the ratio 1: 1 by non-floating regions (Fig. 1, 16). This results in webs and grooves, both in the direction of travel, as well as transversely to the direction of travel. The webs and grooves in the direction of travel stabilize the ride, while the grooves and webs transverse to the direction of travel, increase the braking effect when Schneepflugiahren. The webs have a width and length dimension of about 2cm. The grooves have a width of about 2cm.

The warp yarns (Figures 1, 6) are polypropylene splicing yarn or mono filament

(Fig. 2, 12, 17) formed with a yarn thickness of 0.5mm to 33mm.

The weft threads (Figures 1 and 2, 5) are formed of 2.5 mm thick polyester multifilament yarn (Figure 2, 25). The fabric is coated on the underside with a 0.5 mm thick PVC layer (Fig. 1: 4).

[00109] The covering of the outlet area of a towlift route is effected by the laying on of the 2m wide and 10m long mats. Laterally, the mats are butted against each other and connected at the bottom by Velcro (Figure 4, A). In the direction of travel, which coincides with the longitudinal orientation of the mats, the mats are arranged overlapping 20 cm. [001 10] At the left and right edges the mats are in the direction of travel at a distance of

In fixed by pegs or screws (Fig. 3; 4). The position of the nails to the fabric edge is 5cm. At the top of the mats a flap with a length of 5cm is arranged over the entire width. In this tab there are five eyelet-reinforced holes. The outer holes are arranged 10cm from the right edge. The remaining holes are distributed over the tab at a distance of 45cm. At the bottom are 10cm from the right and left edge each 5 tabs with eyelets (Fig. 3, 3). The lugs have a distance of 2m in the direction of travel. The fixation on the ground is done by pegs (Fig. 3, 4).

[001 1 1 1 The overlapping of the mats in the direction of travel covers the tabs located at the upper edge of the mats.

Example 4

[00111] Example 4 is the textile piste which is used as a sküanglaufmat- te.

[001 13] The mat is made up of 2 layers. The sliding surface (Figures 1, 2) is formed by a web of floating warp yarns (Figures 1, 6 and 10). Underneath a fleece protective layer is arranged (Fig. 1, 34). [001 14] The sliding surface of the fabric (Figures 1, 2) is formed from warp yarns floating over 5 weft yarns (Figures 1, 5) so that the float is 1.3 to 1.6 cm. The floating warp threads lie in the weft direction (Fig. 1, 9) close to each other, so that a nearly closed surface is formed and the warp threads form a large volume of wear. The fabric is oriented in the textile piste so that the longitudinal orientation of the warp threads coincide with the direction of travel (Fig. 1, 7).

[00115] The floating warp threads serving as the sliding surface are formed from the polypropylene material which is particularly slippery. The textile construction of the warp threads is monofilament yarn or splicing yarn (FIGS. 2, 187). The strength of this

Warp threads is 2mm ..

[001 16 j The weft yarns (Figures 2, 5) are made of 2.5 mm polypropylene splicing yarn

(Figure 2, 17).

For the practice of the classic cross-country skiing technique is in the sliding surface a

Double track incorporated. Every lane leads a ski. The distance of the tracks from the track center is 23cm. The track width is 6cm to 7cm. The formation of the track and the guidance of the skis is done by webs, e.g. be formed by folding the piste material. The ridges are 2.5 cm high and are used e.g. fixed by sewing (Figure 8; B; 3).

The total width of the mat is 50cm. The tracks are arranged so that the left and right the same distance to the edge is formed.

The modified by tracks sliding surface is sewn to the underlying nonwoven layer. The fleece is 6mm thick and is made of meshed polypropylene fibers. A cross-country ski run of 400m length is composed of 20 modules or mats, which have a length of 20m, by juxtaposing the end faces. The fixation to the ground takes place on the right and left as well as in the middle of the front sides at a distance of 5cm from the edge by pegs (Fig. 3, 10) and plate dowels (Figure 3, 9). The right and left sides of the mat are anchored at a distance of 5 cm from the edge of each 2m with a peg (Fig. 3; 10) and plate dowels (Fig. 3; 9) to the ground.

From the foregoing description, it will be apparent to those skilled in the art that the individual independent features of the examples may be combined as desired with one another or may occur in several examples.
