    Cable tray section, cable tray and associated mounting method
    The present invention relates to a section of cable tray, formed by a welded wire mesh, an associated cable tray and a method of mounting such a cable tray.
    In particular, the invention relates to cable tray sections, which are designed to form a cable tray once assembled with each other. EP-A-0 973 238 discloses a wire mesh cable duct welded together, having a U-section. This cable tray is formed by a succession of assembled sections. Each section has a reduced section end adapted to be introduced into an enlarged section end of another adjacent section. The enlarged section end has two weft yarns arranged closely to define a slot that has the same width as a weft yarn. Thus, a weft yarn of the reduced section end is inserted into this notch to assemble the sections together. The insertion of the end of a section into the end of the adjacent section is thus done by translation of one section relative to the other in a transverse direction directed towards the inside of the U-section of the section of which the end is of stronger section.
    This cable tray has the disadvantage of being relatively expensive to manufacture insofar as several weft son are necessary to form the notch. FR-A-3 003 098 discloses a lattice and U-section cable duct formed by sections each having a male end and a female end. A weft yarn of the female end includes slots that extend inward in the plane of the bottom of the stump. The male end comprises, in turn, a narrowed section, both in height and width, and a weft thread provided with central off-hooks which have a curvature protruding from the plane of the bottom of the section. The slots of a first section are thus able to pick the central stalls of a second section. On the other hand, the weft yarn of the male end includes side stalls that are designed to snap into warp yarns of the female end of an adjacent stub. The assembly of the sections is thus carried out in two steps: a first step of latching the lateral unhookings, then a step of longitudinal translation of one section with respect to the other to cause picking of the hook by the crenel.
    This cable tray has the disadvantage of being relatively expensive to manufacture, since many wires must be shaped, and to be relatively long to assemble, to the extent that at least two relative movements of the sections in directions different are required to secure these. FR-A-3,007,592 discloses a U-shaped cross-section cable tray defining a bottom and wings. This cable tray is formed by sections each having lateral assembly parts attached to the wings and the bottom at the end of the section. The connecting pieces comprise a hook defining a concavity turned towards the outside of the section and in which a weft thread of the adjacent section can be received, which enables the sections to be assembled together.
    This cable tray is expensive and complex to manufacture taking into account assembly parts that must be reported on the trellis. FR-A-2 966 987 discloses a cable tray comprising wire mesh sections, section U, and can be coupled with each other. The two ends of each section are different from each other. A first of them comprises two U-shaped weft yarns. In the vicinity of this first end, each warp yarn is provided with a re-entrant elbow and an inner nipple. The second of them also includes two weft son, whose deviation distance is the same as that of the weft son of the first end. One of the weft yarns of the second end is also provided with external nipples disposed near the intersections between the weft yarn and the end of the warp yarns. The latter are provided with double re-entrant elbows. To assemble two adjacent sections, it is necessary to translate a section relative to the other in a transverse direction, by engaging the pairs of weft son of the respective ends of the sections against each other. The coupling of the sections is then blocked using reported meeting devices.
    It is understood that the structure of this cable tray is relatively complex, which causes a relatively high manufacturing cost. In addition, its assembly requires reporting separate meeting devices, which represents a substantial loss of time.
    Accordingly, the invention aims to overcome the drawbacks mentioned above by proposing a new section of cable tray particularly easy and inexpensive to manufacture and assemble. The invention relates to a section of cable tray, formed by a welded wire mesh which comprises at least two weft son, which each comprise a central portion and two side portions having an inclination relative to the central portion while being arranged in U, so that the central parts define a bottom of the lattice and the lateral parts define two wings of the lattice, two of the weft yarns respectively forming a first terminal yarn and a second terminal yarn of the lattice, each of the lateral parts of the lattice. second terminal wire comprising a detent vane directed away from the other side portion of the second terminal wire. The mesh also comprises warp yarns, which each connect the weft yarns together and have an end connected to the second terminal yarn, the warp yarns including two edge yarns, which each connect the weft yarns to each other by the yarn. intermediate of one of their respective lateral parts. According to the invention, each edge wire comprises, from the end, a hook portion which forms a concave zone for receiving a first terminal wire of another cable tray section, the concave zone of home having its concavity oriented, in a direction opposite to the other edge wire.
    Thanks to the invention, only one of the ends of the section needs to be shaped in a particular way, the lattice forming the remainder of the section may consist of repeated patterns, so that the section is particularly easy and inexpensive to manufacture. In addition, the latching of the ends between them, provided by the snap-in wings, associated with the hooking of the ends together, by means of the hook parts, allows a particularly simple, fast and reliable assembly of the sections between them.
    According to other advantageous features of the invention, taken singly or in combination: the edge wires each define a trestle axis of the trellis, each of the lateral portions of the second terminal wire comprises an inner sub-part, which extends between the central portion and the latching vane, the inner sub-portions being separated from each other by a first distance, the first distance and the center distance being measured parallel to the bottom of the lattice and perpendicular to the edge, each ratchet wing comprising an oblique sub-part, which extends the inner sub-part, the oblique sub-parts moving away from the central part diverging from one another, an extremal bend ending the sub-part -part oblique, the extremal elbows being separated by a second distance which is greater than the center line spacing, the second distance being measured parallel to the center distance , and a shoulder sub-portion, which extends the extremal elbow and extends towards the other lateral portion, and then opposite the central portion, about the edge axis; each warp thread is provided with a hook portion which forms a concave zone for receiving a first terminal thread of another section of cable tray, each concave receiving area having its concavity open towards the outside the lattice, concave reception areas being distributed along a hook profile corresponding to a profile of the first terminal wire; each of the warp yarns includes a steered bridge portion extending from the hook portion outwardly of the lattice; each hook portion extends between the second terminal wire and another intermediate weft wire closest to the second terminal wire; the weft threads all have an identical profile, except for the second terminal thread which has a profile different from that of the other weft threads; The invention also relates to a cable tray comprising at least a first section and a second section as defined above, the first terminal wire of the second section being hooked into the hook portions of the first section.
    According to an advantageous characteristic of the invention, each edge wire of the second section is in radial abutment on one of the snap-in fins of the first section. The subject of the invention is, moreover, a method of mounting a cable tray as defined above, in which the following steps are carried out: a) placing in radial bearing a first of the wires of the bank of the second section against a first latching wing between the two latching vanes of the first section, b) tilting, around a center line defined by the first edge wire, the second section relative to the first section, by means of the radial support of the first edge wire on the ratchet of the first section, until introduction of the first terminal wire of the second section in the concave reception areas of the first section.
    According to an advantageous characteristic of the invention, the step b) of switching comprises the following substeps: b1) elastic deformation of the second terminal wire of the first section so as to bring the lateral parts of this second terminal wire one of the other, under the action of the second edge wire of the second section exerting a bearing on the second ratchet of the first section as it progresses along the second fin when tilting, b2) back the second terminal wire of the first section in its initial shape by elasticity of the second terminal wire, once the second fin crossed by the second edge wire. The invention will be better understood on reading the description which follows, given solely by way of non-limiting and non-exhaustive example and with reference to the drawings in which: FIG. 1 is a perspective view of a section of cable tray according to a first embodiment according to the invention, - Figure 2 is a top view of the section of Figure 1, - Figure 3 is a side view of the section of Figures 1 and 2, FIG. 4 is a front view on a larger scale of the section of FIGS. 1 to 3; FIG. 5 is a perspective view of a cable tray comprising two sections identical to that of FIGS. 1 to 4; FIG. 6 is a cross-section of the cable tray of FIG. 5, shown during assembly, and FIG. 7 is a perspective view of a cable tray section according to a second embodiment according to FIG. invention.
    FIG. 1 shows a section of cable tray 3 which is designed to form, by assembly with other compatible sections, of the same type or the same, a cable tray 1 as illustrated for example in FIG. 5.
    The cable tray 1 illustrated in Figure 5 is formed by two identical sections 3 and 103 assembled end to end. The reference signs of the section 103 are the same as those of the section 3, increased by 100, to designate the similar or identical elements of the sections 3 and 103.
    In general, the cable tray 1 is modular and can be formed by at least two sections 3 and 103. The number of sections thus assembled determines the length of the cable tray.
    The cable tray 1, and in particular the sections 3 and 103, are formed by welded wire mesh, that is to say a mesh. Each wire is made of metal optionally covered by a protective outer layer, being folded and twisted permanently in a profile. The overall shape of the lattice is obtained by combining the different profiles of the son that constitute it.
    Each section 3 comprises weft threads 5, that is to say transverse threads, and warp threads 7, that is to say longitudinal threads, which are welded to each other so as to form the mesh. In practice, the weft threads 5 each have a curved profile and are preferably regularly spaced from each other. The warp threads 7 each connect the weft threads 5 to each other and are substantially parallel to each other. The lattice is thus formed by a mesh of regular patterned threads. In general, each weft thread 5 is perpendicular to the warp threads 7 with which it is welded.
    Each of the weft threads 5 comprises a central portion 9 and two lateral portions 11 which each extend the central portion 9 from the ends of the latter. As illustrated in FIGS. 1 to 4, the central portion 9 is preferably rectilinear, the two lateral portions 11 having an inclination with respect to the central portion 9 so as to define therewith a U-shape of the weft yarn 5 Preferably, the lateral portions 11 are also substantially rectilinear over at least the majority of their length and each form a right angle with the central portion 9. As a variant, the central portion 9 is curved, as well as, optionally, the Lateral portions 11. In the example of the figures, the rectilinear central portions 9 define a bottom 13 of the grid, which is itself substantially plane and defines a plane tt13 visible in Figure 4. The side portions 11 form two wings 15 of the lattice projecting laterally from the bottom 13 so that the lattice forms an inverted U-shaped tunnel, in which cables or pipes can be arranged substantially parallel to the warp threads 7. If the wings 15 are shown perpendicular to the bottom 13, however, they may have a different orientation, for example divergent or convergent, as long as they are directed on the same side of the plane of the bottom 13 The wings 15 each define a plane tt1 perpendicular to the plane tt1 3.
    Two of the weft threads 5 form respectively a first terminal wire 17 of the mesh, shaped according to a profile P1, and a second terminal wire 19 of the mesh, shaped with a profile P2. The terminal son 17 and 19 are special weft son which are respectively located at the longitudinal ends of the trellis. Each of the intermediate weft threads 7, located between the end wires 17 and 19, is shaped according to a PN profile. The profiles P1 and PN are identical, whereas the profile P2 is different from that of the other weft threads 5 and especially that of the first terminal thread 17. Nevertheless, the profile P1 of the first terminal thread 7, the PN profile of the threads intermediate weft 5 and P2 profile of the second terminal wire 19 generally have a shape of U.
    The profile P1 extends in a transverse plane tt1, the profile P2 in a transverse plane π2, and the transverse profiles PN in transverse planes πΝ, as illustrated in Figures 2 and 3. The planes ττ1, π2 and πΝ are preferably parallel to each other and arranged at an equal distance from each other.
    The warp threads 7 are each connected to each of the weft threads 5, or at least a majority of them, and each extends in a profile PL which is predominantly orthogonal to the transverse planes defined by the threads 5. In particular, a first end 21 of each of the son 7 is connected to the first terminal wire 17 and does not extend beyond the latter. A second end 23 of each warp 7 is, in turn, connected to the second terminal wire 19 and does not extend beyond the latter.
    Each of the PL profiles of the warp threads 7 is included in a longitudinal plane, each longitudinal plane being orthogonal to the set of transverse planes.
    As illustrated in FIGS. 1 to 4, three warp threads 7 form the bottom 13 with the central portions 9 of the weft threads 5. Each wing 15 is itself formed by two warp threads 7 and by the lateral parts 11 Weft yarns 5. The warp yarns 7 include two edge yarns 25, which each connect the weft yarns 5 to each other through one of their respective side portions 11. The edge wires 25 are located at the ends of the weft threads 5 and form a longitudinal edge of the lattice. The edge yarns 25 are welded to the ends of the weft yarns 5. Preferably, the weft yarns 5 are crooked at their ends so as to each form a curved fastener 27 surrounding the edge yarn 25. The particular form of this curved fastener 27 prevents any risk of scratching by the end of the side portions 11. As a variant, the end of the weft threads 5 may on the contrary not be curved, so that the lateral portions 11 of the threads frame 5 are completely straight, which simplifies the manufacture of section 3.
    As illustrated in FIGS. 2 to 4, the PL profiles of the wires 7 and 25 which form the wings 15 each define a plane ttL in which they extend. Similarly, the PL profiles of the son 7 which form the bottom 13 each define a plane tt'L in which they extend.
    The planes πΤ are parallel to each other and perpendicular to the planes ttL. In addition, the planes ttL are perpendicular to the planes π15 and the planes πΤ are perpendicular to the planes π13.
    Each edge wire 25 is coaxial, on at least the majority of its profile PL, to a bank axis X25. The edge wires 25 thus each define a bank axis X25, which bank axes X25 are parallel to each other and perpendicular to the transverse planes π1, π2 and πΝ defined by the weft threads 5. Each edge thread 25 comprises from its end 23, a hook portion 29 which forms a U-shaped concave reception area 31, the concavity of each concave reception area 31 being oriented in a direction opposite to the other edge wire 25, c ' that is to say outside the section 3. The concave reception areas 31 are thus open towards the outside of the U-shaped cross section of the section 3 and are sufficiently wide to accommodate a wire whose diameter is equal to the wire used in the trellis of section 3. As shown in Figure 5, the section 3 is intended to be assembled with a second section 103, the first terminal wire 117 of the second section 103 being hooked in the zones The hook portions 29 are formed by the edge wire 25, the PL profile having a corresponding curvature at this point. The planes of the edge wires 25 are preferably coplanar, so that the hook portions 29 extend in the same plane ttL.
    Each warp thread 5 is advantageously provided with a hook portion 29, as defined above, which forms a concave receiving zone 31 which opens on the outside of the U-shaped cross section of the section 3. In the same way that the X25 edge axes are defined for the edge threads 25, longitudinal axes X7 are defined along which the PL profiles of the other warp threads extend predominantly. in the longitudinal plane ttL or tt'L of the associated PL profile. Each hook portion 29 extends between the second terminal wire 19 and the intermediate weft wire 5 closest to the second terminal wire 19.
    The hook parts 29 extend off-axis with respect to the longitudinal axis X7 or the respective associated axis X25, in the direction of the inside of the U-shaped cross-section of the section 3. The end 23 which ends the hook portion 29 is itself coaxial with the longitudinal axis X7 or the axis of bank X25 respectively. A wire of the same thickness, or the same diameter, as the wires forming the lattice can thus be admitted into each concave receiving zone 31 so that its profile is orthogonal with the longitudinal axis X7 or the axis of bank X25 respectively . In this case, all the concave reception areas 31 are open towards the outside of the trellis being distributed along a hanging profile PA which corresponds to the profile P1 of the first terminal wire 17. Thus, as this is illustrated in FIG. 5, the first terminal wire 117 of the second section 103 is hooked by all the hook portions 29 of the first section 3 while being received in the concave reception areas 31. This first terminal wire 117 is in particular inserted from outside the section 3 until it comes into contact with the bottom of the concave reception areas 31. In this configuration, the second terminal wire 19 of the first section 3 extends parallel and close to the first wire terminal 117 of the second section 103. The sections 3 and 103 are then connected with each other in the direction of the X25 or X7 longitudinal axes, via the hook portions 29.
    Optionally, each of the warp yarns 7, including the edge yarns 25, comprises a bridge portion 33 which is directed outwardly of the lattice and extends from the hook portion 29 by being formed. by a local curvature of the PL profile of the warp thread 7 concerned. The bridge portion 33 is coplanar with the hook portion 29 and extends opposite the latter relative to the longitudinal axis X7 or the axis of the bank X25 respectively. The bridge portion 33 thus extends the reception concavity 31 towards the outside of the U-shaped cross-section. The bridge portion 33 makes it possible to increase the depth of the concave zone 31 by extending the latter over the axis. longitudinal X7 or the axis of bank X25 respectively, which improves the maintenance of the terminal wire 117 of the section 103 within the concave zones 31 parallel to the longitudinal axes X7.
    Furthermore, each lateral portion 11 of the second terminal wire 19 comprises an inner sub-portion 35 which extends from the central portion 9 of this terminal wire 19. Parallel to one of the axes X7, the lateral portions 11 are aligned with the inner sub-portion 35. Thus, the parts 11 and the subpart 35 of the same wing 15 extending in a common plane parallel or coincides with the plane tt15 of the wing 15 concerned. The inner sub-portions 35, as well as each of the side portions 11 of each of the intermediate weft yarns and the first terminal yarn 17, are separated from each other by a first distance d1 which is less than a center distance d X25 shore axes. The first distance d1 and the center distance da are measured parallel to the bottom 13 and perpendicular to the edge wires 25, as can be seen in FIG. 4.
    Each of the lateral portions 11 of the second terminal wire 19 comprises a ratchet wing 37 which is formed by the profile P2 of the terminal wire 19. The ratchet wings 37 extend in the transverse plane defined by the terminal wire 19 and are directed away from each other. In other words, each of the fins 37 is directed away from the opposite side portion 11 of the terminal wire 19. In practice, the inner sub-portion 35 extends between the central portion 9 and the blade fin. latching 37 adjacent.
    Each latching vane 37 comprises an oblique sub-portion 39, which extends the inner sub-portion 35, so that the oblique sub-portions 39 move away from the central portion 9 by diverging from each other according to a gentle and straight slope. The oblique sub-portions 39 are thus arranged in V in the transverse plane of the terminal wire 19. Each oblique sub-portion 39 is terminated by an end elbow 41 of the ratchet blade 37. As illustrated in FIG. the bends 41 are separated by a second distance d2 which is greater than the center distance of the X25 edge axes, the second distance d2 being measured parallel to the center distance da. The extreme elbows 41 are bent inwardly of the U-shaped cross section of the lattice, in the plane of the terminal wire 19.
    Each detent flap 37 further comprises a shoulder subpart 43. Each shoulder subpart 43 extends the end elbow 41 inwardly of the U-shaped cross section and extends in the plane of the yarn. terminal 19, towards the opposite side portion 11 of the terminal wire 19 and then opposite the central portion 9, about the axis of bank X25. In practice, the shoulder sub-portion 43 has substantially a shape of an arc of a circle, for example a quarter circle, and ends with an end which is placed in the axis of the inner sub-portion 35. L the end of the shoulder subpart 43 is merged with one end of the second terminal wire 19. Thus, when the first section 3 and the second section 103 are assembled, as illustrated in FIG. 5, each edge wire 125 of the second section 103 is supported radially, relative to their respective axis X125, on one of the latching wings 37 of the first section 3, and in particular on the shoulder subpart 43 of the fin 37 concerned, which comes into practice surround the edge wire 125 on part of its circumference. In this situation, the edge wires 25 and 125 are coaxial. In general, the warp threads 7 are each coaxial with one of the warp threads 107. The transverse planes of the threads 5 and 105 are parallel to each other. In this situation, the latching fins 37 hold, together with the hook portions 29, the section 3 relative to the section 103 in all directions of space parallel to the planes πΝ. Finally, the sections 3 and 103 are secured to one another in all directions of space.
    To obtain the cable tray shown in Figure 5, it implements a mounting method of this cable tray which is described in the following. In a first step, a first edge wire 125 of the second section 103 is placed in radial abutment against the shoulder sub-portion 43 of a first ratchet blade 37 of the first section 3, as illustrated in FIG. FIG. 6. In this figure, the cable tray 1 is cut in the transverse plane defined by the second terminal wire 19 of the first section 3. During this step, it is arranged to axially align the edge axis 25 with the edge wire 125 which is placed in radial abutment against the ratchet blade 37. During this radial abutment step, the section 3 is inclined with respect to the section 103 about the axis X25, so that the respective extension planes of the wings 15 and 115 are intersecting and intersecting along an axis which is coaxial or parallel with the axis X25.
    In a second step, to secure the sections 3 and 103, the second section 103 is tilted around the axis of bank X25 with respect to the first section along the arrow β in FIG. 6, so as to bring the bottom 13 closer to the background 113 until they become coplanar. If it is placed in the section plane of Figure 6, the first section 3 is thus tilted from the outside to the inside of the U-shaped cross section of the second section 103. The tilting is performed via radial support of the first edge wire 125 of the second section 103 on the ratchet blade 37 of the first section 103 and in particular on the inner sub-portion 35 of the fin 37. The opposite edge wire 125 then in contact with the oblique sub-portion 39 of the second fin 37, which is opposite to the first fin 37 on which the tilting rests. The contacting of this second edge wire 125 with the oblique sub-portion 39 causes an elastic deformation of the second terminal wire 19 of the section 3, which has the effect of bringing its lateral portions 11 towards each other. In practice, the first terminal wire 117 of the second section 103 is also deformed, so that the side portions 111 of the wire 117 are spaced from one another. Indeed, the second edge wire 125 bears against the second ratchet wing 37 as the second edge wire 125 progresses along the oblique sub-portion 39 concerned during tilting. As the second edge wire 125 progresses along the oblique sub-portion 39, the deformation of the second terminal wire 19, and the first terminal wire 117, increases to a maximum value which is reached at the arrival of the second edge wire 125 at the extreme elbow 41. Once the second ratchet wing 37 crossed, and in particular once the extremal elbow 41 crossed, by the second edge wire 125 of the second section , the second terminal wire 19 resumes its initial shape, that is to say takes again the shape of the profile P2 described in the foregoing, by elasticity of the second terminal wire 19. The two edge wires 125 are then each in radial support on one of the shoulder sub-parts 43 associated with one of the ratchet wings 37 of the first section 3. The section 103 and the section 3 are then snapped and secured. This snap-in phenomenon is obtained in particular by virtue of the ratio that exists between the distances d1, d2 and the center distance da defined above.
    Furthermore, thanks to the spatial arrangement of the hook portions 29, when the sections 3 and 103 are snapped, the first terminal wire 117 of the second section 103 is also introduced into the concave reception areas 31 of the first section 3. Thus, at the same time as the latching, the tilting along the arrow β of the section 3 relative to the section 103 also allows the introduction of the first terminal wire 117 in the concave reception areas 31. It is understood that the section 3 can be joined at the section 103 by means of a single operation of switching one section relative to the other. The assembly of sections 3 and 103 is thus particularly fast and easy to perform.
    Disassembly is just as easy. Indeed, as shown in Figure 4, to remove the sections 3 and 103 from one another, it is sufficient to apply a force F1, directed towards the inside of the cross section of the section 3, on one of the lateral portions 11 of the second terminal wire 19 of the first section 3, while applying a force F2, visible in FIG. 5, of opposite direction on the lateral part 111 of the corresponding first terminal wire 117 of the second section 103. thus brings the extreme elbows 41 of the locking lugs 37 towards each other until one of these two bends 41 can be crossed by one of the edge wires 125 of the second section 103. then performs a tilting of the section 3 relative to the section 103 in the opposite direction of the arrow β.
    Advantageously, as illustrated in FIG. 4, the distance d1 separating the internal sub-portions 35 is smaller than a distance d3, measured parallel to d1, separating the lateral portions 11 from the first terminal wire 17. Moreover, the central portion 9 of the second terminal wire 19 is shifted relative to the plane tt13 of the bottom 13, towards the edge son 25, this central portion 9 being parallel to the plane tt13. The internal sub-portions 35 of the section 3 are thus slightly recessed with respect to the lateral portions 111 of the first terminal wire 117 of the adjacent section 103. Similarly, the central portion 9 of the second terminal wire 19 of the section 3 is set back relative to the central portion 109 of the first terminal wire 117 of the adjacent section 103. This allows assembly of the section 3 with the section 103 despite the thickness of the welds of the trellis
    FIG. 7 represents a section 203 according to a second embodiment according to the invention. The reference numbers associated with this second embodiment of FIG. 7 have been increased by 200 relative to those of the first embodiment of FIG. 1 to designate similar or identical elements.
    The section 203 is also formed by a wire mesh which comprises warp yarns 207 and weft yarns 205, which each comprise a central portion 209 and two lateral portions 211 having an inclination with respect to the central portion while being disposed in U, so that the central portions 209 define a bottom 213 and that the side portions define two wings 215. Two of the weft son 205 form respectively a first terminal wire 217 and a second terminal wire 219, each of the side portions of the second terminal wire 219 comprising a latching vane 237.
    Each wing 215 of the section 203 includes only one warp formed in this case by a side wire 225 which connects each of the weft son 205 between them and has an end 223 connected to the second terminal wire 219. wings 215 of the section 203 are thus lower than the wings 15 of the section 3. As a result, the inner sub-portion 235 is of reduced length relative to the inner sub-portion 35.
    Each edge wire 225 comprises, from the end 223, a hook portion 229 which forms a concave receiving zone 231 of a wire, which is open in a direction opposite to the other edge wire 225.
    As a variant, the mesh of the section comprises more or less weft and warp threads than in the two embodiments described in the foregoing. At least each wing of the section comprises a warp wire forming a wire edge and each bottom of the section comprises a warp.
    Alternatively, the constituent son of the section 3, 103 or 203 may be made of synthetic materials.
    The embodiments and variants described in the foregoing may be combined to create new embodiments.
