Definitions
- the invention relates to the field of coated textiles, in particular used in tensile structures such as tents, marquees and other modular constructions, but also as cladding or roofing.
- the invention relates more particularly to specific provisions making it possible to facilitate the positioning of this type of canvas in rigid supports, while retaining good properties of resistance to soiling and to ultraviolet rays.
- a set of metal structures generally forming pillars and a frame are used between which the fabrics are stretched.
- various methods of attachment there is known that which consists in equipping the edges of the fabrics with elements called "ropes" comprising a rod extending on the edge of the canvas. This rod is introduced into a groove made in one of the metal beams of the rigid structure.
- these ropes are made from elements added to the canvas at its edges. More specifically, a textile ribbon is folded back on itself so as to trap the retaining rod.
- This tape generally has a coated face, typically of PVC, and a textile face, for example based on polyester. This ribbon is welded by its coated side at its edges, trapping the edge of the canvas.
- polyester In addition, the sensitivity of polyester to ultraviolet radiation is a factor which causes premature wear of the lines made from polyester.
- a problem which the invention proposes to solve is that of facilitating the sliding of the fabrics when they are placed in a rigid frame, while retaining excellent properties of resistance to soiling, and more generally excellent visual qualities.
- the invention therefore relates to a coated textile sheet whose surface has at least one strip having a lower coefficient of friction than the rest of this same surface. It is characterized in that the strip of lower coefficient of friction is formed by the partial absence of a coating layer present on the rest of the surface.
- the invention consists in producing on the coated textile sheets zones having a lower coefficient of friction, in particular with respect to aluminum. According to the invention, when these sheets are folded back on themselves, they present towards the outside a surface whose thickness of the coating layer is less than that of the rest of the surface. It is this zone which comes into contact with the retaining profiles, in this way, the sliding of this zone trapping the retaining ring is improved, compared to the solutions in which the slings are made from the same coated textile.
- the strip of lower coefficient of friction can be obtained in different ways.
- the strip of lower coefficient of friction can be produced by the non-deposition of a layer present on the rest of the surface of the sheet.
- several elementary layers are deposited successively.
- One or more of these elementary layers may be absent in the zones of the characteristic bands.
- masks can be attached to the coating machine so as to prevent the liquid PVC from some of these elementary layers from depositing in this area, thereby producing a strip with a lesser coating layer thickness compared to the rest of the surface.
- the threads forming the textile core of the sheet may be partially visible at the level of the strip or strips of lesser thickness. Indeed, it is possible to leave a part of the woven threads flush, so as to take advantage of the low coefficient of friction of the textile core, and in particular when it is made of polyester.
- the strip or strips of lower coefficient of friction may be located near the edges of the sheet, so as to allow the flap of the edge of the sheet to fall on itself, and thus form the headline directly from the sheet.
- the sheet after manufacture has a zone folded back on itself which traps a rod, and the strip of lower coefficient of friction is located on all or part of the external surface of the folded zone which traps the rod, and which is intended to come into contact with the groove receiving the canvas.
- the characteristic sheet may comprise several strips of low coefficient of friction, arranged in parallel, so as to allow the manufacture of independent elements, obtained by cutting this sheet. Ribbons are thus obtained which are then folded back on themselves to trap the rod.
- Each strip therefore comprises a strip of lower coefficient of friction which is located on all or part of the outer surface of the zone of the strip trapping the rod.
- FIG. 1 is a cross-sectional view of a sheet of coated textile according to the invention.
- FIG. 2 is a cross-sectional view of an alternative embodiment of FIG. 1.
- Figure 3 is a cross-sectional view of the sheet of Figure 2.
- Figure 4 is a cross-sectional view of a coated textile sheet according to another embodiment of the invention.
- FIG. 5 is a cross-sectional view of a sling forming element produced from a ribbon extracted from the sheet of FIG. 4.
- Figure 6 is a cross-sectional view of a fabric equipped with the rope of Figure 5, placed in a rigid structure.
- the invention relates to coated textiles which are intended to be placed in rigid structures, preferably being kept under transverse tension.
- a coated textile (1) comprises a textile core (2) covered, on each of its faces, with a coating layer (3, 4), based on polymeric material, for example polychloride of vinyl (PVC).
- a coating layer for example polychloride of vinyl (PVC).
- the textile core can for example be made of polyester threads.
- the sheet (1) of coated textile comprises two strips (10, 11) produced on the upper face (6) of the upper coating layer (3). These strips (10, 1 1) are in the example illustrated in Figure 1 made near the edges (12, 13) of the sheet 1.
- these strips (10, 11) can be produced according to different operating modes.
- This trimming can be carried out using abrasive wheels which can equip specific machines, or else be placed at the outlet of the coating machines, upstream from the winding.
- the characteristic strips (10, 1 1) can also be produced not by removing material, but by a partial absence of deposition of the coating layer.
- This coating layer (3) can itself be produced by the superposition of a plurality of elementary layers, some of which are not deposited at the location of the strips (10, 11).
- the trimming depth can be determined as a function of the thickness of the coating layer, and it may for example be sufficient to allow a slight portion of the threads of the textile core to be exposed, especially at the level where the woven threads are most prominent.
- the value of the coefficient of friction of the strip (11) is then influenced by the nature of the threads of the textile core, and this in a direction of decreasing this coefficient.
- the strips (10, 11) are obtained by not depositing a coating layer, it is for example possible to deposit the elementary coating layer which makes it possible to almost completely cover the textile reinforcement ( 3), without however forming any additional thickness. In this case, the threads of the textile core are flush with this elementary layer (21) as shown in FIG. 3.
- the strips (10, 1 1) do not extend to the edge of the sheet itself, but delimit the edges having the same structure as the central portion of the sheet ( 1).
- a coated textile sheet (30) illustrated in FIG. 4 can undergo a treatment allowing it to define several characteristic bands (31, 33,35,37).
- These strips can be produced as already mentioned either by adding a layer of specific material, or by removing part of the coating layer or else by depositing only part of the upper coating layer.
- These different bands (31, 33, 35, 37) are separated by zones (32, 34, 36, 38) in which the coated textile has its nominal composition and thickness.
- the coated textile (30) is cut into several parallel ribbons (50) each comprising a characteristic strip (31, 33, 35, 37), and approximately half of the zone of nominal thickness (32, 34, 36) separating two consecutive characteristic bands.
- Each of these ribbons (50) can then be folded back on itself to trap a rod (54) so that the outer face of this ribbon is formed by the characteristic strip (33), of lower coefficient of friction.
- the two portions of nominal thicknesses (32, 34) are then welded at the level of a zone (52) allowing the portions (32, 34) to be released for their replacement at the edge of a fabric.
- the rope when it is constituted by a flap of the edge of the canvas itself, the rope therefore obviously has the same properties mechanical and aesthetic than the rest of the canvas, which is advantageous in terms of resistance to soiling and other external factors, as well as aesthetically; the rope has the same reaction to fire classification as the rest of the canvas, which is a major advantage compared to the reported rope made generally of PVC and polyester; the extra thickness at the headline is reduced compared to existing solutions, which facilitates the operations of placing the fabric in rigid structures.
