Description

L'invention a trait à un dispositif d'accrochage d'une lisse sur un cordon de harnais de métier à tisser de type Jacquard ou d'un ou plusieurs cordons sur une arcade, ainsi qu'à un métier Jacquard équipé d'un tel dispositif. L'invention a également trait à un procédé de fabrication d'un tel dispositif, ainsi qu'à un procédé d'accrochage d'une lisse sur un cordon de harnais Jacquard au moyen d'un tel dispositif.The invention relates to a device for attaching a stringer to a Jacquard loom harness cord or to one or more strings on an arch, and to a Jacquard loom equipped with such a stringer device. The invention also relates to a method of manufacturing such a device, and to a method of attaching a stringer to a Jacquard harness cord by means of such a device.

Un crochet de mécanique Jacquard est classiquement associé à une arcade à laquelle est ou sont reliés un ou plusieurs cordons, l'ensemble des cordons constituant le harnais de la mécanique Jacquard. Dans sa partie inférieure, chaque cordon doit être accroché à l'extrémité supérieure d'une lisse qui comprend un oeillet de passage d'un fil de chaîne. Pour réaliser cet accrochage, il est connu de EP-A-0 915 195 de surmouler, à l'extrémité supérieure d'une lisse, un embout qui forme un orifice de passage et de coincement de la partie inférieure d'un cordon, une gaine souple en matière synthétique étant alors glissée autour de l'embout pour aider à l'immobilisation de la partie inférieure du cordon. Pour exercer un effort de serrage significatif, une telle gaine doit avoir une épaisseur relativement importante, ce qui entraîne des frottements entre les différentes gaines montées sur des lisses adjacentes lors du croisement de deux lisses animées de mouvements opposés, lorsque la densité d'implantation des lisses est élevée. Ces gaines doivent également être relativement longues pour exercer un effort de serrage suffisant. En pratique, la longueur de ces gaines est au moins supérieure à leurs courses pour éviter que leurs extrémités s'accrochent entre elles. Il en résulte que ces gaines, de longueur et de diamètre importants, forment un ensemble compact en partie supérieure des lisses, cet ensemble limitant l'accès aux fils de chaîne à travers le harnais lors des opérations de maintenance. Il arrive également que ces gaines fluent, ce qui induit un risque de glissement des cordons par rapport aux embouts.A Jacquard mechanical hook is conventionally associated with an arcade to which is or are connected one or more cords, the set of cords constituting the harness of the Jacquard mechanism. In its lower part, each bead must be hooked to the upper end of a heddle which comprises an eyelet for the passage of a warp yarn. To achieve this hanging, it is known to EP-A-0 915 195 overmolding, at the upper end of a rail, a tip which forms a passage opening and jamming of the lower part of a bead, a flexible plastic sheath then being slid around the end piece to help the immobilization of the lower part of the cord. To exert a significant tightening force, such a sheath must have a relatively large thickness, which causes friction between the different sheaths mounted on adjacent smooth at the crossing of two smooth moving with opposite movements, when the density of implantation of smooth is high. These sheaths must also be relatively long to exert sufficient clamping force. In practice, the length of these sheaths is at least greater than their races to prevent their ends cling to each other. As a result, these sheaths, of large length and diameter, form a compact assembly at the top of the rails, this assembly limiting access to the warp threads through the harness during maintenance operations. It also happens that these ducts fluent, which induces a risk of sliding cords relative to the end caps.

Il existe par ailleurs des gaines thermo-rétractables qui sont mises en place sur les extrémités supérieures des lisses après qu'un cordon ait été noué. Une fois thermo-rétractées, ces gaines ont une forme extérieure très irrégulière qui est l'image de la forme qu'elles enveloppent, cette forme extérieure présentant des protubérances génératrices d'usures prématurées, lors des contacts répétés à la croisure entre les gaines montées sur des lisses adjacentes.In addition, there are heat-shrinkable sheaths that are placed on the upper ends of the stringers after a cord has been tied. Once heat-shrunk, these sheaths have a very irregular outer shape which is the image of the shape they envelop, this outer shape having protuberances generating premature wear, during repeated contacts at the cross between the mounted sheaths on adjacent rails.

Il est également connu de FR-A-2 822 479 d'utiliser un tronçon tubulaire en matière plastique ou en métal pour serrer l'extrémité inférieure d'un cordon dans une fente longitudinale ménagée dans un embout surmoulé à l'extrémité supérieure d'une lisse. La forme en V de la fente ne permet pas un serrage efficace du cordon, qui risque de glisser lors du fonctionnement du métier, ce qui rend imprécise la commande de la lisse et peut induire des fautes dans la foule. En outre, la fente, qui s'étend sur toute la longueur de l'embout, fragilise cet embout au niveau de la zone de surmoulage de la lisse. Un embout complémentaire doit être monté en partie inférieure du tronçon tubulaire, ce qui complique le montage. Enfin, avant le coincement du cordon, le tronçon tubulaire est complètement séparé de l'embout, de sorte qu'il peut glisser jusqu'au niveau de l'oeillet ou du bas de la lisse.It is also known to FR-A-2,822,479 using a tubular section of plastic or metal to clamp the lower end of a cord into a longitudinal slot in a molded tip at the upper end of a bar. The V shape of the slot does not allow effective tightening of the cord, which may slip during operation of the trade, which makes imprecise the control of the bar and can induce faults in the crowd. In addition, the slot, which extends over the entire length of the tip, weakens this tip at the overmolding area of the smooth. A complementary tip must be mounted at the bottom of the tubular section, which complicates the assembly. Finally, before binding the cord, the tubular portion is completely separated from the tip, so that it can slide to the level of the eyelet or the bottom of the smooth.

C'est à ces inconvénients qu'entend plus particulièrement remédier l'invention en proposant un nouveau dispositif d'accrochage dont l'encombrement diamétral peut être très réduit, ce qui permet une grande densité d'implantation des lisses, qui permet un accrochage efficace et dont le montage est aisé.It is these drawbacks that the invention more particularly intends to remedy by proposing a new fastening device whose diametral size can be very small, which allows a high density of implantation of the healds, which allows effective fastening. and whose assembly is easy.

Dans cet esprit, l'invention concerne un dispositif d'accrochage d'un premier élément d'un ensemble de formation de la foule dans un métier à tisser de type Jacquard sur un second élément appartenant à cet ensemble, le dispositif d'accrochage comprenant un embout surmoulé sur l'extrémité supérieure du premier élément et comportant deux premières branches entre lesquelles est définie une ouverture de passage de l'extrémité inférieure du second élément, cette extrémité comprenant deux brins qui s'étendent vers le haut à partir d'une portion de ce second élément reçu dans cette ouverture. Ce dispositif est caractérisé en ce que l'embout comporte deux deuxièmes branches entre lesquelles est défini un logement de réception des brins précités et en ce qu'il comprend également un manchon métallique monté sur l'embout et mobile en translation sur cet embout entre une première position, où le manchon permet l'accès à l'ouverture précitée et n'interagit pas avec les deuxièmes branches, et une seconde position, où le manchon exerce sur les premières branches et sur les deuxièmes branches un effort centripète de resserrement de l'ouverture et du logement et de coincement de la portion précitée de l'extrémité inférieure du second élément et des brins adjacents, respectivement dans l'ouverture et dans le logement définis par l'embout.In this spirit, the invention relates to a device for attaching a first element of a crowd forming assembly in a Jacquard loom to a second element belonging to this assembly, the attachment device comprising a tip overmolded on the upper end of the first element and having two first branches between which is defined a passage opening of the lower end of the second element, this end comprising two strands which extend upwards from a portion of this second element received in this opening. This device is characterized in that the endpiece comprises two second branches between which is defined a receiving housing of the aforementioned strands and in that it also comprises a metal sleeve mounted on the endpiece and movable in translation on this endpiece between a first position, wherein the sleeve allows access to the aforementioned opening and does not interact with the second branches, and a second position, wherein the sleeve exerts on the first branches and on the second branches a centripetal tightening force opening and housing and wedging of the aforementioned portion of the lower end of the second element and adjacent strands, respectively in the opening and in the housing defined by the tip.

L'utilisation d'un manchon métallique permet que celui-ci demeure cylindrique avec une section prédéterminée, en pratique circulaire, après sa mise en place sur l'embout équipé du cordon. Ainsi, l'encombrement diamétral du dispositif d'accrochage peut être bien maîtrisé, ce qui limite les risques d'usure par frottement. Compte tenu de son caractère rigide, le tube peut exercer un effort de serrage suffisant, alors qu'il peut être sensiblement plus court et moins épais qu'une gaine classique. Il en résulte que l'accessibilité à la partie inférieure du harnais ou à la partie supérieure du jeu de lisses est grandement améliorée, de même que l'accessibilité aux fils de chaîne pour des réparations manuelles à travers le harnais. Compte tenu de la faible longueur du manchon, le dispositif peut être léger. Compte tenu du diamètre réduit du manchon, les forces de frottement sont fortement diminuées, voire supprimées. Du fait de la rigidité du manchon, la tenue au glissement du cordon est stable dans le temps. Le fait que les brins adjacents à la portion du second élément engagée dans l'ouverture sont reçus dans le logement défini entre les deuxièmes branches permet d'obtenir un effort de blocage réparti sur la longueur de ces brins, ce qui est particulièrement efficace.The use of a metal sleeve allows it to remain cylindrical with a predetermined section, in practice circular, after its introduction on the endpiece equipped with the cord. Thus, the diametral size of the attachment device can be well controlled, which limits the risk of wear by friction. Given its rigid nature, the tube can exert sufficient clamping force, while it can be substantially shorter and less thick than a sheath classic. As a result, accessibility to the lower portion of the harness or upper portion of the heald set is greatly improved, as well as accessibility to the warp yarns for manual repairs through the harness. Given the short length of the sleeve, the device can be lightweight. Given the reduced diameter of the sleeve, the friction forces are greatly reduced or suppressed. Due to the rigidity of the sleeve, the resistance to sliding of the cord is stable over time. The fact that the strands adjacent to the portion of the second element engaged in the opening are received in the housing defined between the second branches makes it possible to obtain a blocking force distributed over the length of these strands, which is particularly effective.

Selon des aspects avantageux mais non obligatoires de l'invention, un tel dispositif peut incorporer une ou plusieurs des caractéristiques suivantes:

  • Les secondes branches sont pourvues d'extrémités libres distantes l'une de l'autre lorsque le manchon est dans sa première position et qui forment ensemble l'extrémité supérieure de l'embout lorsque le manchon est dans sa seconde position.
  • Une première extrémité du manchon, qui se trouve vers l'avant de celui-ci lorsqu'il passe de sa première à sa seconde position, est évasée vers l'avant. Dans ce cas, la seconde extrémité du manchon peut être convergente en s'éloignant de sa première extrémité.
  • Le manchon et l'embout sont pourvus de moyens complémentaires qui forment une butée d'arrêt du mouvement de translation du manchon de sa première vers sa seconde position. Grâce aux moyens d'arrêt, un positionnement du tube est obtenu, ce qui facilite le montage et le contrôle visuel du bon positionnement en hauteur des lisses. L'esthétique du harnais est également améliorée. On peut prévoir que le manchon et l'embout sont également pourvus de moyens complémentaires formant butée d'arrêt du mouvement de translation du manchon de sa seconde vers sa première position. Les moyens formant butée comprennent avantageusement un relief ménagé sur une surface périphérique externe de l'embout et contre lequel vient en appui une extrémité du manchon lorsque le manchon parvient dans l'une de ses positions à partir de l'autre position. Le relief peut comprendre au moins une dent contre laquelle vient en appui une extrémité du manchon lorsque le manchon parvient dans sa première position à partir de sa seconde position, cette dent étant compatible avec un déplacement du manchon vers sa première position, à partir d'une position opposée à la seconde position.
  • Le manchon et l'embout sont pourvus de moyens complémentaires d'immobilisation du manchon sur l'embout dans la seconde position, par coopération de formes. Ces moyens d'immobilisation peuvent également constituer des moyens de butée d'arrêt du mouvement de translation du manchon, de sa première vers sa seconde position. Ces moyens d'immobilisation comprennent avantageusement au moins un relief rentrant formé dans une partie courante du manchon, ainsi qu'au moins un relief complémentaire ménagé sur une partie de l'embout qui est élastiquement déformable lorsque le manchon passe de sa première à sa seconde position. On peut prévoir que le relief complémentaire est ménagé sur l'une des deux premières branches.
  • Le manchon est en acier inoxydable ou en alliage à base de cuivre, avec une épaisseur de parois inférieure à 0,6 mm, de préférence inférieure à 0,3 mm, de préférence encore de l'ordre à 0,1 mm.
  • L'embout présente, au niveau ou au voisinage de chacune de ses extrémités, une zone globalement conique ou tronconique et convergente en s'éloignant de l'extrémité opposée. Ceci permet de limiter les risques d'accrochage entre des dispositifs adjacents montés sur un métier.
  • Les deuxièmes branches sont pourvues de moyens de centrage de l'un des brins selon un axe longitudinal de l'embout.
According to advantageous but non-mandatory aspects of the invention, such a device may incorporate one or more of the following features:
  • The second legs are provided with free ends distant from each other when the sleeve is in its first position and which together form the upper end of the nozzle when the sleeve is in its second position.
  • A first end of the sleeve, which is towards the front of it when it passes from its first to its second position, is flared forward. In this case, the second end of the sleeve may be converging away from its first end.
  • The sleeve and the tip are provided with complementary means which form a stop of the translation movement of the sleeve from its first to its second position. Thanks to the stop means, a positioning of the tube is obtained, which facilitates the assembly and the visual control of the correct positioning in height of the smooth. The aesthetics of the harness is also improved. It can be provided that the sleeve and the end piece are also provided with complementary means forming stop stop of the translational movement of the sleeve of its second to its first position. The means forming a stop advantageously comprise a relief formed on an outer peripheral surface of the endpiece and against which one end bears against the end of the sleeve when the sleeve reaches one of its positions from the other position. The relief may comprise at least one tooth against which one end of the sleeve comes to bear when the sleeve reaches its first position from its second position, this tooth being compatible with a displacement of the sleeve towards its first position, starting from a position opposite to the second position.
  • The sleeve and the endpiece are provided with complementary means for immobilizing the sleeve on the endpiece in the second position, by cooperation of forms. These immobilization means may also constitute stopping means for stopping the translation movement of the sleeve, from its first to its second position. These immobilizing means advantageously comprise at least one recess formed in a current portion of the sleeve, and at least one complementary relief formed on a portion of the tip which is elastically deformable when the sleeve passes from its first to its second position. It can be provided that the complementary relief is provided on one of the first two branches.
  • The sleeve is made of stainless steel or copper-based alloy, with a wall thickness of less than 0.6 mm, preferably less than 0.3 mm, more preferably of the order of 0.1 mm.
  • The tip has, at or near each of its ends, a generally conical zone or frustoconical and convergent while moving away from the opposite end. This limits the risk of snagging between adjacent devices mounted on a trade.
  • The second branches are provided with means for centering one of the strands along a longitudinal axis of the endpiece.

The invention will be better understood and other advantages thereof will appear more clearly in the light of the following description of three embodiments of a fastening device and a Jacquard loom consistent with its principle, given only by way of example and with reference to the appended drawings in which:

Le métier M représenté à la figure 1 est équipé d'une mécanique Jacquard 2 qui commande plusieurs arcades 4 dont une seule est représentée et dont l'extrémité inférieure est associée à plusieurs cordons 6, l'ensemble des cordons formant le harnais H du métier. L'extrémité inférieure 6a de chaque cordon 6 est reliée à l'extrémité supérieure 8a d'une lisse 8, chaque lisse étant pourvue d'un oeillet 8b de passage d'un fil de chaîne 10 et soumise à l'action d'un ressort de rappel' 12 fixé au cadre 14 du métier par une tige 16.The trade M represented at figure 1 is equipped with a Jacquard mechanism 2 which controls several arches 4 of which only one is shown and whose lower end is associated with several cords 6, the set of cords forming the harness H of the craft. The lower end 6a of each bead 6 is connected to the upper end 8a of a rail 8, each rail being provided with an eyelet 8b for passing a warp wire 10 and subjected to the action of a return spring '12 fixed to the frame 14 of the loom by a rod 16.

Les lisses 8 peuvent également être commandées individuellement par la mécanique 2, auquel cas chaque cordon 6 est déplacé individuellement par cette mécanique.The rails 8 can also be controlled individually by the mechanism 2, in which case each cord 6 is moved individually by this mechanism.

Au sens de la présente description, l'adjectif « supérieur » se rapporte à une partie ou un élément d'un dispositif dirigé vers le haut dans une configuration normale d'utilisation du métier M, c'est-à-dire vers le haut à la figure 1, alors que l'adjectif « inférieur » désigne une partie ou un élément dirigé vers le bas dans cette configuration.As used herein, the term "superior" refers to a portion or element of an upwardly facing device in a normal pattern of use of the loom M, i.e., upwardly to the figure 1 , while the adjective "inferior" designates a part or element directed downwards in this configuration.

Un dispositif d'accrochage 20 est utilisé pour relier l'extrémité supérieure de 8a de chaque lisse 8 avec l'extrémité inférieure 6a du cordon 6 correspondant. Ce dispositif 20 comprend un embout 22 surmoulé sur l'extrémité 8a sous la forme d'un corps 221 globalement cylindrique à section circulaire. Au-delà de l'extrémité 8a, le corps 221 se prolonge par deux branches 222 et 223 entre lesquelles est définie une ouverture 224 dont les dimensions dans le plan des figures 3 et 5 peuvent varier en fonction d'un rapprochement possible des branches 222 et 223 qui sont élastiquement déformables.An attachment device 20 is used to connect the upper end of 8a of each arm 8 with the lower end 6a of the cord 6 corresponding. This device 20 comprises a tip 22 overmolded on the end 8a in the form of a generally cylindrical body 221 with circular section. Beyond the end 8a, the body 221 is extended by two branches 222 and 223 between which is defined an opening 224 whose dimensions in the plane of the Figures 3 and 5 may vary depending on a possible approximation of the branches 222 and 223 which are elastically deformable.

Les branches 222 et 223 se rejoignent dans une zone 225 opposée au corps 221 à partir de laquelle s'étendent deux autres branches 226 et 227 dont les extrémités libres 226a et 227b s'étendent à distance l'une de l'autre lorsque l'embout 22 n'est pas contraint, comme représenté aux figures 2 et 3.The branches 222 and 223 meet in an area 225 opposite the body 221 from which extend two other branches 226 and 227 whose free ends 226a and 227b extend at a distance from each other when the tip 22 is not constrained, as shown in figures 2 and 3 .

L'extrémité 6a du cordon 6 peut être engagée dans l'ouverture 224. Les deux brins 6b et 6c formés par le cordon 6, de part et d'autre de sa partie 6d reçue dans l'ouverture 224, longent alors la zone 225 et sont engagés dans un interstice 228 traversant défini entre les branches 226 et 227. Les deux brins 6b et 6c s'étendent vers le haut à partir de la portion 6d du cordon 6 qui est reçue dans l'ouverture 224.The end 6a of the cord 6 can be engaged in the opening 224. The two strands 6b and 6c formed by the cord 6, on either side of its portion 6d received in the opening 224, then go along the zone 225 and are engaged in a through gap 228 defined between the branches 226 and 227. The two strands 6b and 6c extend upwardly from the portion 6d of the cord 6 which is received in the opening 224.

Comme représenté par les flèches F1 et F2 à la figure 2, l'extrémité 6a peut être engagée dans l'ouverture 224, puis les brins 6b et 6c peuvent être rabattus vers l'interstice 228 qui forme ainsi un logement de réception de ces brins.As represented by the arrows F 1 and F 2 at the figure 2 the end 6a can be engaged in the opening 224, then the strands 6b and 6c can be folded towards the gap 228 which thus forms a housing for receiving these strands.

On note X22 l'axe longitudinal central de l'embout 22, cet axe étant confondu avec l'axe longitudinal X8 de la lisse 8.X 22 is the central longitudinal axis of the endpiece 22, this axis coinciding with the longitudinal axis X 8 of the rail 8.

Chaque branche 222 et 223 est pourvue d'une partie 222a, 223a rentrant en direction de l'axe X22 par rapport au reste des branches 222, 223. Ces parties 222a et 223a définissent ainsi deux zones 222b et 223b en creux par rapport aux surfaces externes 222c et 223c des branches 222 et 223 sur la majeure partie de leur longueur.Each branch 222 and 223 is provided with a portion 222a, 223a returning in the direction of the X axis 22 relative to the rest of the branches 222, 223. These portions 222a and 223a thus define two zones 222b and 223b recessed relative to the external surfaces 222c and 223c of the branches 222 and 223 over most of their length.

Un manchon métallique 24 est rapporté sur l'embout 22 et destiné à verrouiller l'extrémité 6a du cordon 6 par rapport à cet embout, lorsque le réglage en hauteur de la lisse 8 a été effectué en ajustant la position de cette extrémité 6a par rapport à l'embout 22. De façon tout à fait avantageuse, le manchon 24 est en acier inoxydable ou dans un alliage à base de cuivre tel que le laiton, de sorte qu'il ne risque pas de rouiller, même si le métier M est susceptible de fonctionner dans un environnement humide ou agressif. Le manchon 24 est à section circulaire sur la majeure partie de sa longueur et sa paroi est mince, son épaisseur étant inférieure à 0,3 mm, de préférence voisine de 0,1mm. En pratique, l'épaisseur de paroi du manchon 24 peut être choisie inférieure à 0,6 mm.A metal sleeve 24 is attached to the endpiece 22 and intended to lock the end 6a of the cord 6 relative to this endpiece, when the height adjustment of the arm 8 has been made by adjusting the position of this end 6a relative at the end 22. In a very advantageous manner, the sleeve 24 is made of stainless steel or in a copper-based alloy such as brass, so that it will not rust, even if the craft M is likely to operate in a humid or aggressive environment. The sleeve 24 is of circular section over most of its length and its wall is thin, its thickness being less than 0.3 mm, preferably close to 0.1 mm. In practice, the wall thickness of the sleeve 24 may be chosen less than 0.6 mm.

L'extrémité 241 du manchon 24 est évasée, c'est-à-dire divergente en s'éloignant de sa partie courante 242. L'extrémité opposée 243 est convergente en direction de l'axe central X24 du manchon 24 et en s'éloignant de la partie 242.The end 241 of the sleeve 24 is flared, that is to say divergent away from its current portion 242. The opposite end 243 is convergent towards the central axis X 24 of the sleeve 24 and s 'away from part 242.

On note L24 la longueur du manchon 24. Cette longueur est sensiblement inférieure à celle des gaines souples utilisées, par exemple, avec le dispositif connu de EP-A-0 915 195 . En pratique, la longueur L24 est comprise entre 10 et 40 mm, de préférence de l'ordre de 20 mm.The length L of the sleeve is noted 24 24. This length is substantially less than that of the flexible sheaths used, for example, with the known device EP-A-0 915 195 . In practice, the length L 24 is between 10 and 40 mm, preferably of the order of 20 mm.

Le manchon 24 est pourvu de trois emboutis localisés 244, régulièrement répartis autour de l'axe X24 et rentrants en direction de cet axe. Ces trois emboutis ou rétreints définissent le diamètre intérieur minimal du manchon 24, c'est-à-dire le diamètre extérieur nominal d'une pièce pouvant être reçue dans ce manchon au niveau de ces emboutis.The sleeve 24 is provided with three localized stampings 244, regularly distributed around the X axis 24 and reentrants in the direction of this axis. These three stampings or necking define the minimum inside diameter of the sleeve 24, that is to say the nominal outside diameter of a piece that can be received in this sleeve at these stampings.

Le corps 221 est pourvu de deux dents 221a définies chacune entre une surface 221b perpendiculaire à l'axe X22 et une surface 221c inclinée en direction de cet axe en s'éloignant de l'ouverture 224.The body 221 is provided with two teeth 221a each defined between a surface 221b perpendicular to the X axis 22 and a surface 221c inclined towards this axis away from the opening 224.

Lorsqu'il convient de fabriquer le dispositif 20, le manchon 24 est mis en forme avec des techniques classiques de découpage et d'emboutissage. Puis, il est glissé sur l'extrémité 8a de la lisse 8 et déplacé à distance de cette extrémité, en direction de l'oeillet 8b. L'embout 22 est alors surmoulé sur l'extrémité 8a. On peut ensuite ramener le manchon 24 vers sa première position représentée aux figures 2 et 3, ce qui est possible malgré la présence des dents 221a du fait du caractère incliné des surfaces 221c qui permettent le franchissement des dents 221a par l'extrémité 243. Une fois ce franchissement réalisé, la dent 221 forme une butée à un mouvement du manchon 24 en direction de l'oeillet 8b. On est alors dans la configuration des figures 2 et 3.When the device 20 is to be manufactured, the sleeve 24 is shaped using conventional cutting and stamping techniques. Then, it is slid on the end 8a of the smooth 8 and moved away from this end, towards the eyelet 8b. The tip 22 is then overmolded on the end 8a. The sleeve 24 can then be returned to its first position shown in FIGS. figures 2 and 3 , which is possible despite the presence of the teeth 221a because of the inclined surfaces 221c which allow the crossing of the teeth 221a by the end 243. Once this crossing achieved, the tooth 221 forms a stop to a movement of the sleeve 24 in the direction of eyelet 8b. We are then in the configuration of figures 2 and 3 .

En variante, le manchon 24 peut être conservé à distance de l'embout 22 ou engagé sur cet embout sans toutefois que son extrémité 243 ne dépasse les dents 221a.Alternatively, the sleeve 24 may be kept at a distance from the tip 22 or engaged on this tip without its end 243 protruding from the teeth 221a.

Une fois l'extrémité 6a du cordon 6 mis en place et le réglage de la hauteur de la lisse réalisée, le cordon est coupé en longueur pour ménager le brin 6b, alors que le brin 6c se prolonge vers le haut pour constituer la partie intermédiaire du cordon 6. Le manchon 24 est alors déplacé dans le sens des flèches F3, c'est-à-dire selon un mouvement de translation parallèle aux axes X22 et X24 alors confondus et dans une direction d'éloignement par rapport à l'oeillet 8b de la lisse 8. Ceci permet d'atteindre la seconde position représentée aux figures 4 et 5 dans laquelle l'extrémité 241 du manchon 24 vient en appui contre un épaulement 229 formé en deux partie 229a et 229b sur les surfaces externes des branches 226 et 227. Ainsi, l'extrémité 241 et l'épaulement 229 constituent une butée au déplacement du manchon 24 de sa position de la figure 2 à celle de la figure 4. Du fait de ce déplacement, les branches 222 et 223, d'une part, et les branches 226 et 227, d'autre part sont rapprochées l'une de l'autre en resserrant l'ouverture 224 et l'interstice 228. En effet, le caractère rigide du manchon 224 lui permet d'exercer sur les branches 222, 223, 226 et 227 un effort centripète E1 en direction des axes X22 et X24, cet effort étant suffisant pour bloquer les brins 6b et 6c dans l'interstice 228, par rapprochement des extrémités 226a et 227a, et pour coincer la partie 6d de l'extrémité 6a dans l'ouverture 224.Once the end 6a of the cord 6 set up and the adjustment of the height of the smooth realized, the cord is cut in length to provide the strand 6b, while the strand 6c extends upwards to form the intermediate The sleeve 24 is then moved in the direction of the arrows F 3 , that is to say in a translational movement parallel to the axes X 22 and X 24, which are then merged and in a direction away from the eyelet 8b of the rail 8. This makes it possible to reach the second position represented in FIGS. figures 4 and 5 in which the end 241 of the sleeve 24 abuts against a shoulder 229 formed in two parts 229a and 229b on the external surfaces of the branches 226 and 227. Thus, the end 241 and the shoulder 229 constitute a stop to the displacement of the sleeve 24 of its position of the figure 2 to that of the figure 4 . Because of this movement, the branches 222 and 223, on the one hand, and the branches 226 and 227, on the other hand, are brought closer to one another by tightening the opening 224 and the gap 228. Indeed, the rigid nature of the sleeve 224 allows it to exert on the branches 222, 223, 226 and 227 a centripetal force E 1 in the direction of the X 22 and X 24 axes, this effort being sufficient to lock the strands 6b and 6c in the gap 228 by bringing the ends 226a and 227a closer together, and to wedge the portion 6d of the end 6a into the opening 224.

A ce niveau, on obtient un effet d'amplification de l'effort de serrage E1 qui est exercé par le manchon 24 au niveau des parties 222a et 223a pour « fermer » les branches 222 et 223 qui ont tendance à pivoter autour de leurs points d'attache sur la zone 225. L'extrémité 6a du cordon est ainsi fermement pincée dans l'ouverture 224 alors aplatie. Les brins 6b et 6c sont quant à eux également fermement pressés contre la zone 225 et serrés entre les branches 226 et 227 du fait de l'effort E1.At this level, an amplification effect of the clamping force E 1 is obtained which is exerted by the sleeve 24 at the portions 222a and 223a to "close" the branches 222 and 223 which tend to pivot around their attachment points on the 225 area. The end 6a of the cord is thus firmly pinched in the opening 224 then flattened. The strands 6b and 6c are themselves also firmly pressed against the zone 225 and clamped between the branches 226 and 227 due to the effort E 1 .

Comme il ressort plus particulièrement de la figure 5A, les surfaces en regard 226b et 227b des branches 226 et 227 sont concaves, avec une forme leur permettant de centrer le brin 6c sur l'axe X22 lorsque l'effort E1 les rapproche l'une de l'autre. Dans l'exemple représenté à la figure 5A, les surfaces 226b et 227b comprennent chacune deux portions parallèles reliées par une portion inclinée.As is clear from the Figure 5A , the facing surfaces 226b and 227b of the branches 226 and 227 are concave, with a shape enabling them to center the strand 6c on the X axis 22 when the effort E 1 brings them closer to each other. In the example shown in Figure 5A , the surfaces 226b and 227b each comprise two parallel portions connected by an inclined portion.

Comme représenté à la figure 5B pour une variante de l'invention, les surfaces 226b et 227b peuvent être globalement en forme de V ouvert-, ce qui permet également le centrage du brin 6c sur l'axe X22.As represented in Figure 5B for a variant of the invention, the surfaces 226b and 227b may be broadly V-shaped open, which also allows the centering of the strand 6c on the X axis 22 .

Les sections correspondantes aux figures 5A et 5B sont prises dans une partie de l'embout 22 où seul est présent le brin 6c, le brin 6b étant reçu dans le logement 228 sur une partie seulement de la hauteur de ce logement.The sections corresponding to Figures 5A and 5B are taken in a portion of the tip 22 where only the strand 6c is present, the strand 6b being received in the housing 228 on only a portion of the height of this housing.

Le déplacement du tube 24 de sa première position vers sa deuxième position permet d'amener l'un des emboutis 244 au niveau de l'une des zones 222b et 223b des branches 222 et 223, ce qui induit une immobilisation par clipsage du manchon 24 sur l'embout 22 dans la configuration des figures 4 et 5. Ainsi, l'effort de serrage du manchon 24 est pérenne.The movement of the tube 24 from its first position to its second position makes it possible to bring one of the stampings 244 at one of the zones 222b and 223b of the branches 222 and 223, which induces immobilization by clipping the sleeve 24. on the tip 22 in the configuration of the figures 4 and 5 . Thus, the clamping force of the sleeve 24 is perennial.

Les zones 222b et 223b et les emboutis 244 peuvent également servir de butée au déplacement du manchon 24 de sa première vers sa seconde position. Dans ce cas, le manchon est plus court que celui représenté sur les figures, de telle sorte que son extrémité avant 241 n'interfère pas avec l'épaulement 229, l'arrêt du déplacement F3 du manchon de sa première vers sa seconde position étant obtenu lorsque les emboutis 244 s'engagent dans les zones 222b et 223b.The zones 222b and 223b and the stampings 244 can also serve as an abutment for moving the sleeve 24 from its first position to its second position. In this case, the sleeve is shorter than that shown in the figures, so that its front end 241 does not interfere with the shoulder 229, stopping the displacement F 3 of the sleeve from its first to its second position being obtained when the embossed 244 engage in the zones 222b and 223b.

Dans tous les cas, le fait que l'extrémité avant 241 du manchon 24 est évasée évite que celle-ci ne marque ou de blesse la matière plastique constituant l'embout 22 lors du déplacement du manchon de sa première vers sa seconde position. Le caractère évasé de l'extrémité 241 est représenté sur la figure comme résultant d'une déformation vers l'extérieur de l'extrémité 241. En variante, ce caractère évasé pourrait être obtenu par un chanfrein intérieur de l'extrémité 241 dont la surface extérieure ne serait pas déformée.In all cases, the fact that the front end 241 of the sleeve 24 is flared prevents it from marking or injures the plastic material constituting the tip 22 when moving the sleeve from its first to its second position. The flared character of the end 241 is represented in the figure as resulting from an outward deformation of the end 241. In a variant, this flared character could be obtained by an inner chamfer of the end 241 whose surface exterior would not be distorted.

L'immobilisation obtenue dans la configuration des figures 4 et 5 est réversible, en ce sens qu'il est possible de déplacer à nouveau le manchon 24 vers la position des figures 2 et 3 en chassant les emboutis 244 des zones 222b et 223b par une déformation élastique des branches 222 et 223, du même type que celle qui se produit au terme de la course du déplacement du manchon 24 de sa première vers sa deuxième position.The immobilization obtained in the configuration of figures 4 and 5 is reversible, in that it is possible to move the sleeve 24 again to the position of the figures 2 and 3 by driving the stampings 244 of the zones 222b and 223b by an elastic deformation of the branches 222 and 223, of the same type as that which occurs at the end of the stroke of the displacement of the sleeve 24 from its first to its second position.

L'utilisation du manchon 24 permet de maîtriser et dé limiter l'encombrement diamétral du dispositif 20, le diamètre extérieur maximal D20 du dispositif 20 étant alors déterminé par l'épaisseur des branches 226 et 227, sans que le manchon 24 n'augmente ce diamètre.The use of the sleeve 24 makes it possible to control and limit the diametral size of the device 20, the maximum outside diameter D 20 of the device 20 then being determined by the thickness of the branches 226 and 227, without the sleeve 24 increasing. this diameter.

Les lisses peuvent donc être implantées avec une grande densité, alors que les risques d'usure prématurée des dispositifs d'accrochage sont diminués, voire supprimés.The healds can therefore be implanted with a high density, while the risk of premature wear fastening devices are reduced or even eliminated.

Le corps 221 forme, dans sa partie opposée aux branches 226 et 227, un tube de faible diamètre 221d raccordé à la partie principale du corps 221 par une zone tronconique 221e convergente en direction de l'oeillet 8b. Dans la configuration des figures 4 et 5, les surfaces d'extrémité externes 226c et 227c des branches 226 et 227 sont arrondies et convergentes vers l'axe X22, à l'opposé de la zone 225, avec une forme globalement tronconique. L'extrémité supérieure du dispositif 20 définie par ces surfaces est ainsi conformé pour limiter les chocs ou les frottements avec des dispositifs voisins lorsque ce dispositif se déplace vers le haut par rapport aux dispositifs voisins. La zone 221e a la même fonction lorsque le dispositif 20 se déplace vers le bas.The body 221 forms, in its portion opposite the branches 226 and 227, a small diameter tube 221d connected to the main body portion 221 by a frustoconical zone 221e converging towards the eyelet 8b. In the configuration of figures 4 and 5 the outer end surfaces 226c and 227c of the legs 226 and 227 are rounded and converging towards the X axis 22 , opposite the zone 225, with a generally frusto-conical shape. The upper end of the device 20 defined by these surfaces is thus shaped to limit shocks or friction with neighboring devices when the device moves upwards relative to neighboring devices. Zone 221e has the same function when the device 20 is moving down.

Compte tenu de sa faible épaisseur et de sa longueur L24 relativement modeste, le manchon 24 est léger et n'augmente pas sensiblement l'inertie de l'ensemble formé d'un cordon 6 et d'une lisse 8. Du fait de la très bonne définition de l'emplacement du tube 24 dans la position des figures 4 et 5, grâce aux moyens de butée 229 et 241 et/ou 222b et 223b il est aisé de contrôler sa bonne mise en place notamment lorsque de nombreuses lisses sont juxtaposées dans une configuration prédéterminée, dans la mesure où les manchons correspondant doivent alors être sensiblement alignés.Given its small thickness and its relatively modest length L 24 , the sleeve 24 is light and does not significantly increase the inertia of the assembly formed by a cord 6 and a smooth 8. Because of the very good definition of the location of the tube 24 in the position of figures 4 and 5 thanks to the abutment means 229 and 241 and / or 222b and 223b, it is easy to check that it is correctly positioned, particularly when a number of rails are juxtaposed in a predetermined configuration, insofar as the corresponding sleeves must then be substantially aligned.

Le mode de déplacement du manchon 24 de sa première position vers sa seconde position, voire, en sens inverse, permet d'envisager une automatisation du mouvement correspondant, ce qui induit un gain de temps et de main d'oeuvre appréciable.The mode of movement of the sleeve 24 from its first position to its second position, or even in the opposite direction, makes it possible to envisage an automation of the corresponding movement, which induces a saving of time and appreciable labor.

Compte tenu du caractère réversible de la mise en place du manchon 24 dans la position des figures 4 et 5, un ajustement en longueur du cordon peut être envisagé, le manchon 24 étant déplacé temporairement vers sa configuration des figures 2 et 3 puis remis en place dans sa configuration des figures 4 et 5, sans altération de l'effort de serrage obtenu grâce au manchon 24.Given the reversible nature of the implementation of the sleeve 24 in the position of the figures 4 and 5 , a length adjustment of the cord may be considered, the sleeve 24 being temporarily moved to its configuration of figures 2 and 3 then put back into place in its configuration of figures 4 and 5 , without alteration of the clamping force obtained by the sleeve 24.

La figure 8 concerne un second mode de réalisation pour lequel les éléments analogues à ceux du premier mode de réalisation portent les mêmes références. L'ouverture 224 de ce mode de réalisation n'est pas complètement entourée de matière, la branche 223 étant interrompue et formant une ouverture 223o d'introduction latérale de la portion 6d du cordon 6 dans l'ouverture 224. Une fois le manchon 24 en place, cette portion 6d est pincée dans l'ouverture 224 par les branches 222 et 223.The figure 8 relates to a second embodiment for which elements similar to those of the first embodiment bear the same references. The opening 224 of this embodiment is not completely surrounded by material, the branch 223 being interrupted and forming an opening 223o lateral introduction of the portion 6d of the cord 6 in the opening 224. Once the sleeve 24 in place, this portion 6d is pinched in the opening 224 by the branches 222 and 223.

Dans le dispositif de l'invention, la partie du corps 221 dans laquelle est surmoulée l'extrémité 8a de la lisse est distincte de la partie formée des éléments 222 à 229 grâce à laquelle l'extrémité 6a du cordon est bloquée. Ainsi, la structure d'accrochage du cordon ne risque pas d'affaiblir la liaison entre l'embout 22 et la lisse 8.In the device of the invention, the part of the body 221 in which is overmolded the end 8a of the bar is distinct from the portion formed of the elements 222 to 229 thanks to which the end 6a of the cord is blocked. Thus, the attachment structure of the cord does not risk weakening the connection between the tip 22 and the smooth 8.

Le manchon 24 a été représenté avec une section circulaire continue. I1 pourrait être fendu longitudinalement ou formé par enroulement d'une feuille de métal avec recouvrement partiel.The sleeve 24 has been shown with a continuous circular section. It could be split longitudinally or formed by winding a metal sheet with partial overlap.

Le dispositif peut également servir pour la liaison entre un ou plusieurs cordons 6 et une arcade 4 de métier Jacquard. Dans ce cas, la ou les extrémité(s) supérieure(s) du ou des cordon (s) 6 est ou sont surmoulée (s) dans le corps 221 et l'extrémité inférieure de l'arcade 4 est coincée dans l'ouverture 224.The device can also be used for the connection between one or more cords 6 and a Jacquard loom 4. In this case, the upper end (s) of the cord (s) 6 is or are overmolded in the body 221 and the lower end of the arch 4 is stuck in the opening 224.
