Definitions
- the present invention relates to the technical field of weaving but it relates, more particularly, to the field of fabrics having a vocation of industrial use.
- the arrangement of the fibers of a fabric has a great influence on its performances which can be of resistance, in one or more preferential directions, or of aptitude to marry surface conformations, in particular when such fabrics are used as reinforcements used in the composition of a composite material by being associated with a matrix, for example made of resin.
- the technique of manufacturing parts made of composite materials is currently particularly suited to the production of technical parts of more or less complex shapes and having to present a certain lightness as well as optimal resistance.
- this ability to marry the model is generally qualified as topping or draping, a quality that a fabric with a technical vocation must be able to present in association with the previous requirement.
- One such technique consists in passing the width of traditional fabric between pressure rollers beyond which the fabric is taken up by a receiving roller whose axis is inclined at a given angle relative to the direction of the pressure rollers.
- the fixing process generally involves the supply of a binding product, the presence of which can have a detrimental effect on the subsequent behavior of the tissue in its binding with its composite matrix.
- the prior art has known another proposal consisting in producing a fabric with traditional weft and warp threads, but which is produced in the form of a continuous tubular sheath.
- the principle then consists in cutting such a sheath along a helical trajectory, for example oriented at 45 °, so as to have, after opening and flattening, a woven sheet whose threads are oriented at an angle.
- the production of such a sheath can be ensured from a traditional loom or a circular loom.
- the prior art has also proposed using an assimilated process for obtaining a bias fabric. This involves using an open braiding machine which effectively makes it possible to produce a strip whose interlaced threads are oriented at an angle relative to the direction of production of the strip.
- an open braider consists of a supply of yarn from bobbins which are subjected to rotation on their axis, so that the same problems of yarn change are here to be taken into account.
- an open braider does not generally and practically make it possible to achieve a width of width which is large enough to respond positively to the requirements charged for a bias fabric, in particular in a technical application.
- the need is still felt to be able to have a bias fabric that can be produced continuously by being free of all faults and drawbacks which are to be taken into account currently known technical solutions.
- the bias fabric according to the invention is characterized in that it is in the form of a finished length (L) and width (1) width, made up of interlaced threads, established in respective directions oblique to the length (L) and none of which has knotting, even for an infinite length (L) of the width.
- the subject of the invention is also a process for the continuous production of a bias fabric of the above type, such a process being characterized in that it consists in: • warping a ply of direction threads (x-x ') parallel to each other by having them taken care of by a first and a second transfer means occupying parallel directions (y-y') between them which form an angle ( ⁇ ) with the direction (x-x '),
- the invention also relates, for the production of a fabric of the above type, to a weaving loom characterized in that it comprises
- a warping section of a sheet of threads established successively, parallel to each other from a border for establishing the sheet
- first and second means for taking over and oblique transverse transfer of said wires towards an edge of the so-called recovery ply, said means being established parallel to each other in an oblique direction ( ⁇ ) relative to that of the threads and this oblique direction defining the direction and the production direction of the width, • a third means established at a distance and parallel to the first and driven in the same direction as the first two, so as to support the substantially middle part of the ply yarn occupying the recovery edge,
- Fig. 1 is a schematic plan view partially showing a width of bias fabric according to the invention.
- Figs. 2 to 6 are schematic views illustrating different phases of implementation of the method.

- Figs. 13 and 14 are perspectives illustrating certain constructive details of the trade.
- Fig. 15 is a schematic elevation showing other constituent elements of the trade in an alternative embodiment.
- Fig. 16 is a plan view taken substantially along line XVI-XVI of FIG. 15.
- Fig. 17 is an elevation similar to FIG. 15 but showing another functional characteristic.
- Fig. 18 is a plan view taken substantially along line XVIII-
- Figs. 19 and 20 are plan views, similar to FIGS. 16 and 18 but illustrating another example of armor.
- the bias fabric according to the invention is illustrated diagrammatically in FIG. 1 which shows that this fabric is in the form of a width 1 of length L and width 1 finished.
- the length L must be considered to be infinite, that is to say capable of presenting a large footage while having homogeneous constructive characteristics over the entire length.
- the width is made up of threads 2 and 3 which are intertwined or intertwined according to all appropriate weaves, the most general being the taffeta frame.
- the wires 2 and 3 are established in respective directions D and d which are oblique with respect to the direction of the length L.
- the directions D and d are orthogonal and symmetrical with respect to the direction L making with respect to this last each an angle which is generally qualified in the technique of plus or minus 45 °.
- the directions D and d could have a different obliquity with respect to the direction of the length L with, understandably the incidence of a behavioral heterogeneity of the tissue obtained due to the existence of different angular directions and not symmetrical with respect to the direction L and complementary in value such as for example + 50 ° and - 40 °.
- the wires 2 and 3 are of finite lengths and are interrupted on at least one of the selvedges such as la relative to the other such as lb.
- the fabric width may include threads such as 2 which form a loop 4 every two times at one of the selvedges such as lb.
- the width 1 may also include selvedges 1a and 1b furnished with a loop 5 formed by a ribbon or cord or by a coating of suitable material, added during manufacture to trap, either the cut ends of the wires 2 and 3, either the loops 4.
- the width 1 comprises at least one straight reinforcing thread 6 which extends parallel to the direction L of the width.
- a reinforcing wire is then trapped between the wires 2 and 3 which can be of single-strand or multi-strand, monofilament or multifilament nature and have a flat section of small thickness or a different cross-sectional conformation such as circular.
- the elementary wires 2 and 3 can be of any suitable material, and in particular of carbon fibers.
- the width is produced over an infinite length L from elementary threads
- the width 1 can be produced over an infinite length L from elementary yarns 2 and 3 of flat shape and which, in such a case, are free from twisting on their entire length, even in the case where the wires 2 form an open loop 4 in line with one of the selvedges such as lb.
- the procedure according to the invention is as follows. First of all, a warping plane such as P shown in phantom in FIG. 2, so as to have a border 10 ′, called establishment and a border 10 ′′, called recovery and which is parallel to the establishment border
- the plane P is, moreover, delimited transversely to the borders 10 by a first means 11 and a second support and transfer means 12 which are parallel to each other extending over the entire width between the borders 10, while making with the direction xx 'of these latter a determined angle ⁇ , for example equal to 45 °.
- the means 11 and 12 thus occupy the same direction y-y 'which is oblique to the direction x-x'.
- the distance between the parallel means 11 and 12 is advantageously chosen at most equal, or even slightly less than twice the width taken between the edges 10 'and 10 ", perpendicular to the direction x-x' .
- the method also involves a third take-over and transfer means 13 extending in the same direction ⁇ relative to the reference xx 'from the return edge 10 "which it intercepts by its input section while being arranged parallel to the means 11.
- the means 11 to 13 can be driven, in the same direction as that of the arrow fi, by intermittent synchronous movements or step by step or even continuous.
- a wire 15 is unwound from a reel 14 which is established, under relative tension, in line with the border
- the wire 15 once established as said above, is sectioned upstream of the support means 11 relative to the direction of unwinding, so that there then remains on the warping plane P an elementary wire 15 ⁇ .
- the means 15 and 12 are then moved simultaneously by the means 11 and 12 driven simultaneously in the direction of the arrow fi, in the transverse direction to allow establishment, as described above. , a second wire 15 2 to the right of the establishment border 10 '.
- the method involves a means 13, the inlet of which is aligned with that of the means 11, so that this alignment occupies a direction zz 'which is perpendicular to the direction x-x'.
- a crowd is opened in an area such as 16 located below the aligned inlets of the means 11 and 13.
- Such an opening is carried out by suitable means for moving the sheet of wires 15
- the opening of the crowd 16 can occur, for example by raising one thread in two.
- the wire 15 ⁇ is then cut by a member 17 located just upstream from the entrance to the means of transport 13 (fig. 4), so as to leave between the entry of this means 13 and approximately the output of the first means 11, a 15 ⁇ wire segment that will be designed to constitute subsequently a wire 2 of the strip 1.
- the second part 15i b 15 ⁇ cut wire is maintained between the output of means 12 and means 18 for gripping and insertion capable of being driven at least by a movement in the direction of the arrow h.
- This segment of wire 15i b is then inserted into the shed 16 by the member 18 so as to be arranged parallel to the inputs of the support means 11 and 13 in the direction zz 'to be engaged thereafter by a striking operation can be considered classic in weaving.
- each segment of wire 15 hail b lying between the inlet of the means of transport 13 and that of the means of transport 11, is inserted into the shed 16 and taken care of by the means of transport 11 and 13 by constituting as shown in fig. 6 an elementary thread which is crossed with the threads 2 held between the conveyors 11 and 13 to give rise to the formation of a width which progresses in the direction of the arrow f 3 in the direction yy 'defining the direction L of production.
- fig. 6 that gradually establishes the width 1 composed of son 2 and 3 which are perpendicular to each other while being oriented obliquely with respect to the direction of progression y-y'-L, according to the angle ⁇ .
- the width woven at an angle can be qualified by plus or minus 45 ° for the orientation of the threads 2 and 3.
- the process implemented as described above involves various additional phases, one of which d 'they is the adaptation of the second means 12 on a sliding carriage or on an oscillating assembly capable of being moved in the direction of the arrow f to compensate for the variation in length of the wires 15 arrivingfollowing the opening of the crowd 16
- each wire, 15 n established in line with the border 10 ' corresponds to a unwinding from the coil 14 over an elementary length. close to that of the warping plane P, then to a cut by a member 19 located between the coil 14 and the means 11 and preceded by a retaining clamp or the like 20 (fig. 2).
- Each loop 5 can be formed by a ribbon, a cord or a strip of material appropriate or may result from an addition by coating, removal or molding of a coating of material chosen from those capable of possessing a residual flexibility which is compatible with that of the width 1.
- Each loop 5 can be definitively added or temporary.
- the object of the invention makes it possible to constitute a width 1 of finite width I and of infinite length L by using only one thread such as 15 from the spool 14 to constitute the elementary threads 2 and 3 which, consequently, and whatever the length of the width 1, are always free from points of junction, knotting, binding.
- the width thus obtained is of a homogeneous nature in its constitution, in its presentation and in its technical characteristics, and can be manufactured over an infinite length by the simple replacement of a reel 14 of large capacity which is simply changed when it is is no longer in the state, with the only winding remaining on it, to deliver a length of elementary wire capable of being established between the inputs of the carriers 11 and 12.
- Such a characteristic makes it possible to have rates of uninterrupted industrial production and thus to produce a width of bias fabric of infinite length without the manufacturing process experiencing phases of interruption which are made necessary, as is practiced in the technique of usual weaving, for knotting interrupted threads when changing bobbins in particular, as well as by any necessary intermediate operations, such as warping and filling of bobbins and cans. This results in a significant reduction in the cost of production.
- the wires 15 n could come from more than one coil 14, with or without alternation, each corresponding to a title and / or to a given constituent material.
- the opening operation of the crowd 16 as described above involves a local displacement of the son concerned in raising and / or lowering, so as to respect, as is traditional in weaving, the weave desired for the interlacing of the wires 2 and 3.
- Such an opening can be carried out by the implementation of a system of combs ensuring the functions of lateral guidance of each of the wires, of opening and closing of the half - tablecloths and striking each segment of wire cut from that occupying the recovery edge 10 ".
- Fig. 6 shows that, according to a variant of the process, it can be expected to take advantage of the opening of the crowd 16 to insert at least one straight reinforcing thread 6 trapped between the interlaced threads 2 and 3 and extending parallel to the direction y-y'-
- Fig. 7 shows, schematically, an example of construction of a weaving loom capable of implementing the method described above to obtain the bias fabric according to the invention.
- the weaving loom generally designated by the reference M, comprises a warping section 21 which is intended to delimit the plane P described above.
- This warping section 21 is essentially constituted by the two support conveyors 11 and 12 which form the means parallel to each other for taking over and moving direction across the different wires 15 "warped as said above.
- the conveyors 11 and 12 each consist of two duos of endless conveyor belts, the upper strands 22 and lower 23 facing each other are superimposed and pressed so as to maintain the end portions of each wire 15 acknowledged.
- the conveyor belts 22 and 23 can be simple belts or belts with pins or needles or with hooking or adhesive coating. To define a 10 'establishment border and a recovery border
- the lower conveyor belts 23 of the means 11 and 12 have a length less than that of the belts 22 to define, in a way, zones of entry and exit of the wires 15"
- the two means 11 and 12 are, as said previously, established parallel to each other having the same length and each making an angle ⁇ with respect to the direction of the borders 10 ′ and 10 ′′ of the plane P whose establishment length occupies the direction x- x '.
- the orientation of the conveyors 11 and 12 is established in the direction y-y 'which corresponds to the production direction L of the width of bias fabric.
- the means 11 and 12 are distant from each other in the direction x-x ', preferably by a measurement equal to twice the width considered perpendicular to the direction x-x', between the borders 10 'and 10 ".
- the weaving loom furthermore comprises a third means of handling and transfer designated by the reference 13 and which responds to the constructive characteristics of the means 11 and 12, or even to characteristics equivalent on the technical level.
- the means 13 therefore also comprises an upper conveyor belt 22 and a lower conveyor belt 23.
- the means 13 is located parallel to the means 11, so that its entry is able to take care of the warped wire occupying the recovery edge 10 "in the middle part of the latter.
- the entry 30 of the means 12 and that 31 of the means 13 are aligned in the direction zz 'which is orthogonal to the direction x-x'.
- the angle ⁇ is close to 45 ° and the length of the third support and transfer means 13 is calculated so that its outlet is substantially aligned with the outlet of the means 12 in a direction which is perpendicular to direction y-y '.
- the take-over and transfer means are responsible for ensuring the displacement in the oblique direction yy 'of the ply yarns warped 15 n and, to this end, are driven, by drive members not shown but conventional in the matter, for driving preferably intermittent synchronous displacements according to a pitch which corresponds, elementarily, to the spacing to be respected between each wire 15 n of the warped ply.
- the loom comprises a cylinder 32 for winding the width 1 produced.
- This distance is advantageously taken advantage of to have means 33 capable of bordering the edges of the width 1 produced by means of a strap, a ribbon, a band, etc. ..., or to ensure the filling of a coating of any suitable material. It should be considered that such a lining could also come from the prior deposition, for example at the entrance of the means 11 and 13, of a layer of adhesive product intended to support the ends of the wires and then, to be detached from the conveyor belts to form the edge coatings.
- Such a method of handling can also be adopted with regard to the conveyor belts of the means 12 by providing, in addition to the exit zone 34, a film or a peeling film, so as to strip the conveyor belts 22 and 23 as they escape from the 10 "recovery edge.
- the weaving loom also comprises a device 40 for placing each elementary yarn 15 n , in line with the establishment border 10 '.
- a device is, for example, constituted by a gripper 41 which is adapted to a carriage or other motor member capable of being guided in motorized reciprocating movement in one and / or the other direction of the arrow fs, so as to be able to take the wire 15 from a spool 14, to pass it over the inlet section of the conveyor 11 and then bring it to the inlet section of the conveyor 12.
- the stroke according to the arrow fs takes into account the presence of the cutting member 19 which is located beyond the clamp 20 taking into account the direction of wire unwinding relative to the spool 14.
- the position of the clamp 20 can be considered to be approximately that of taking over by the clamp 41 during the extension-unwinding phase of the wire 15.
- the weaving loom further comprises an opening-closing section 45 of the shed 16 by acting on the ply of warped threads to form it into two half-plies.
- a system 45 comprises, according to FIGS. 7 to 12, a plurality of combs or the like 50 loaded, to take charge of the wires 15 n to ensure lateral guidance and step-by-step transfer, if necessary, maintaining their selected relative spacing.
- These combs 50 are advantageously each constituted by two walls 51 delimiting a kind of stirrup open upwards and responsible for guiding a wire 15 n .
- the walls 51 are mounted at the end of an elastically deformable blade 52 which is linked to a displacement drive system 53 capable of adopting different structural forms.
- the system 53 is constituted by an endless belt 54 capable of being driven by an intermittent movement in the direction of the arrow f & passing over return members 55 having the effect of establishing some of the blades 52 in the same plane under the warping plane P with for said bars an orientation of the stirrups open upwards.
- the blades 52 are also associated with lifters 56 which can be controlled in any suitable manner and selectively according to the armor chosen to be raised from a position of erasure, as illustrated in figs. 9 and 10 to an elevation position, as illustrated in FIG. 11.
- Each raised pusher acts on the corresponding blade to deform it upwards, so that the comb 50 raises the corresponding wire 15 n to delimit, in relation to those held in place, the shed 16 in which the segment of wire 15 administrat b , cut from the wire 15 n occupying the recovery edge 10", is inserted, as described in connection with the process.
- the opening-closing system 45 is advantageously mounted on a chassis 57 which is carried by a bench 58 relative to which it can be moved by a suitable drive member to be driven by a displacement in the double direction of the arrow f 7 relative to the initial position in which it opens the crowd 16.
- the pushers 56 are controlled in retraction, so as to bring all the combs back to the original position in which they are aligned parallel to the warping plane P (fig. 12).
- the drive member is controlled to move the entire system on the bench 58 in the direction of alignment of the inlet sections 30 and 31 of the support means 11 and 13, so that the different combs 50 assume a flapping function for striking and pressing the inserted segment of thread 15 administrat b against the previous ones in the manner of what occurs in conventional weaving, as shown in FIG. 12.
- the weaving loom is finally provided, again, with the gripping and insertion member 18 which is intended to take charge of the free end after cutting the segment 15 " b of thread 15" occupying the recovery edge 10 " , to insert it into the crowd 16.
- a member can be constituted by a gripping pliers adapted at the end of a lance 61 capable of being introduced into the crowd, for example from the establishment border 10 ' It goes without saying that a reverse arrangement can also be envisaged. In all cases, the lance is driven by an alternative rectilinear stroke which is sufficient to insert the segment of cut wire 15 nb into the crowd 16 over the entire width. of the hatched tablecloth.
- the lance 61 can also be replaced by two opposite half-lances provided, each at the end, with complementary gripping means and driven by rectilinear displacements inversely synchronized. It is also possible to provide the member 61 in the form of an actuator with reciprocating rectilinear displacement, provided with lateral gripping means. and which would be, in a waiting position, immobilized parallel to the segment of wire to be cut in line with the recovery edge lb ".
- Such a gripping member would then be mounted on a vertical pivot located near the cutting section of the wire, so that after taking over, it can be subjected to a rotation in order to bring the gripper 18 which it comprises in the axis of the shed, inside which the segment of wire 15 n b cut, and taken in its entirety, would then be inserted
- the member 61 is arranged to support the end of the segment 15 administrat b cut by the cutting member 17 which is located near the inlet section 31 of the means 13.
- the loom is additionally provided with an inflection finger 70 which, in a embodiment, consists of a vertical cylindrical rod , located substantially in line with the recovery edge 10 "and at a distance from the cutting member 17.
- an inflection finger 70 which, in a embodiment, consists of a vertical cylindrical rod , located substantially in line with the recovery edge 10 "and at a distance from the cutting member 17.
- Such a finger is retractable, so that it can be controlled in elevation after displacement across the wire 15 n brought to the right of the border 10 "A functional sequence can then be established in the following manner.
- the gripping member such as the clamp 18, grips the wire 15 n occupying the recovery edge 10 ", then the cutting member 17 is actuated to cut said wire and leave a first segment of wire 15 na which remains is retained to the right of the outlet of the means 11 and the inlet of the means 13 to subsequently constitute a wire 2.
- the member 18 can then be controlled in displacement movement inside the shed 16 in a direction perpendicular to the direction x-x ', so that the segment of wire 15 handed b cut is driven and caused to bypass the inflection point 70 to be disposed and suitably aligned inside the shed 16.
- the wire used and unwound from the spool 14 is of the flat type, being for example constituted by a association of ultra-filaments of carbon fibers which may, for example, be of the 3K, 6K, 12K, or even 24K, 48K, 80K type.
- the inflection point 70 can then, advantageously, be produced as illustrated in FIG. 13 by being constituted by a finger 71 associated with a bar 72 delimiting with the finger a passage window of restricted width.
- the finger 71 extends, above the ply of warped thread 15 ", so that the last thread occupying the recovery edge 10" is engaged between the finger 71 and the strip 72.
- the arrangement of the inflection point 70 is made so that the finger 71 extends obliquely to the direction x-x ', being oriented at 45 ° to be directed towards the crowd 16.
- the same effect can be obtained by using dynamic rather than static components and by replacing finger 71 with a turning bar capable of possibly being rotated on its axis by 180 ° immediately after actuation of the cutting member 17, so that the end portion 15 ′ nb , comprised between the turning bar and the cutting member, is automatically, after turning, oriented in the direction favorable to being taken over by the cutting member gripping, such as 18, moving parallel to the crowd 16, as illustrated in FIG. 14.
- the inflection point 70 could also include instead of the bar
- the loom may include a device for inserting at least one straight reinforcing wire, such as the wire bearing the reference 6 in FIGS. 1 and 6.
- a device designated as a whole by the reference 80 in FIGS. 15 and 16, comprises a wire guide bar 81 carrying at least one eyelet 82 in which is engaged the wire 6 which is unwound from a superimposed coil not shown.
- the wire guide bar 81 is disposed in abutment against the combs 50 between the latter and the alignment of the inputs 30 and 31 of the handling and transfer means 11 and 13. Beyond the eyelet 82, each wire 6 is inserted into the shed 16 to be trapped in a crossover zone between a thread 2 and a thread 3 making up the width of bias fabric 1.
- the insertion device then comprises, for each reinforcing thread 6, a retractable needle 83 which ensures, in its lowering position, as illustrated in FIG. 15, maintaining the part of the reinforcing wire 6 trapped in line with the last wire 3 inserted and at a distance from the eyelets 82.
- the needles 83 are retracted, as illustrated in FIG. 17, so as to allow insertion at the bottom of the last segment 15 administrat b of inserted wire.
- the needles 83 are moved in a reverse movement in order to keep each thread 6 in the waiting position, as illustrated in FIG. 18.
- each pivoting needle 83 is offset from the eyelet 82 corresponding to it by a width of elementary wire 15 ".
- Figs. 16 and 18 show an example of weaving the width 1 in a satin weave.
- Figs. 19 and 20 illustrate an example of weaving according to the invention with the adoption of a 2/1 twill weave, with position of the eyelets 82 when inserting the segment of thread 15 nb (fig. 19) and when striking said thread segment (fig. 20).
- the invention finds a preferred application in the production of so-called technical fabrics at ⁇ 45 ° and reserved for the production of shaped parts from a matrix of synthetic material in which said fabric is embedded as a reinforcing reinforcement.
