Description

MECANISME DE FORMATION DE LA FOULE ET METIER A TISSER EQUIPE D'UN TEL MECANISME L'invention a trait à un mécanisme de formation de la foule pour un métier à tisser. Elle concerne, notamment, les mécanismes de tirage dans lesquels des bielles sont utilisées pour transmettre à des cadres de lisse un mouvement généré par une ratière ou une mécanique d'armure. L'invention concerne également un métier à tisser équipé d'un mécanisme du type précité. Dans le domaine de formation de la foule sur les métiers à tisser, il est connu d'utiliser des bielles qui assurent l'accouplement des organes mobiles d' actionnement ' avec des cadres de lisses à déplacement vertical montés sur le métier. Il est connu, par exemple de FR-A-2 836 488, qu'une bielle de transmission d'effort peut comprendre une partie tubulaire dans laquelle est engagé un embout pourvu d'un œillet d'attelage à un levier oscillant ou un bras d'entraînement. Pour tenir compte des nombreuses configurations d' installation des mécanismes de formation de la foule, il est par ailleurs connu de prévoir des bielles réglables en longueur, avec une partie portant un œillet et formant une tige destinée à être introduite et verrouillée à l'intérieur d'une partie tubulaire, grâce à une vis coopérant avec un écrou prisonnier dans la partie tubulaire et exerçant sur la tige un effort de pression contre une barrette également disposée dans la tige. Cette approche impose de prévoir des moyens de retenue, à l'intérieur de l'extrémité de la partie tubulaire, à la fois pour l' écrou et pour la barrette de réception de l'effort d'appui. Une telle approche impose également de prévoir des moyens de guidage de la tige pour éviter des déplacements parasites selon une direction transversale perpendiculaire à celle selon laquelle est appliqué l'effort d'immobilisation obtenu grâce à l' écrou. Ces contraintes induisent une construction élaborée pour l'extrémité de la partie tubulaire de la bielle, ce qui augmente son prix de revient sans que la précision obtenue soit, en pratique, satisfaisante. En outre, ces dispositions constructives peuvent gêner l'introduction totale de la tige dans la partie tubulaire, ce qui induit que la longueur minimale de la bielle ne peut pas être diminuée en deçà d'une valeur limite. C'est à ces inconvénients qu'entend plus particulièrement remédier l'invention en proposant un nouveau mécanisme de formation de la foule dont la ou les bielles peuvent être aisément réglée (s) en longueur selon la configuration du métier à tisser, alors que son prix de revient demeure économique et que la précision de l'ajustement en longueur des bielles et sa fiabilité sont conformes aux exigences du domaine technique et permettent un fonctionnement du métier à tisser à haute vitesse. Dans cet esprit, l'invention concerne un mécanisme de formation de la foule pour métier à tisser, ce mécanisme comprenant au moins une bielle réglable en longueur et/ou démontable comportant une première partie pourvue d'une tige apte à coulisser dans une partie tubulaire, ainsi que des moyens d' immobilisation de cette tige en position dans cette partie tubulaire, caractérisée en ce que cette bielle est équipée d'un fourreau dont le volume interne forme un logement de réception et de centrage de la tige par rapport à la partie tubulaire, ce fourreau étant disposé à l'intérieur de cette partie tubulaire et assurant le maintien en position par rapport à cette partie tubulaire d'au moins un des moyens d'immobilisation de la tige en position dans la partie tubulaire. Grâce à l'invention, le fourreau qui est introduit dans l'extrémité de la partie tubulaire de la bielle assure plusieurs fonctions, à savoir le centrage de la tige par rapport à la partie tubulaire et le positionnement d'un ou de plusieurs moyens d'immobilisation, alors que la partie tubulaire est lisse et dépourvue de reliefs, ce qui facilite grandement sa fabrication. Selon des aspects avantageux mais non obligatoires, un mécanisme de formation de la foule peut incorporer une ou plusieurs des caractéristiques suivantes prises dans toute combinaison techniquement admissible : Le fourreau est au moins en partie élastiquement déformable. - Le fourreau porte ou forme au moins un organe de centrage par rapport à la surface intérieure de la partie tubulaire. Cet organe est avantageusement constitué par une patte élastiquement déformable et monobloc avec une partie du fourreau formant le logement précité de réception et de centrage de la tige, cette patte étant prévue pour venir en appui contre la surface intérieure de la partie tubulaire . - Le fourreau est réalisé en matière synthétique, de préférence injectée, notamment en matière plastique injectée. - Les moyens d'immobilisation précités comprennent une barrette immobilisée par le fourreau dans partie tubulaire, par coopération de formes, cette barrette étant prévue pour recevoir en appui la tige. Dans ce cas, la face de cette barrette destinée à recevoir la tige en appui ainsi que la face de cette barrette tournée vers la surface intérieure de la partie tubulaire sont pourvues de reliefs destinés à augmenter l'adhérence entre cette barrette et la tige, d'une part, et la partie tubulaire, d'autre part. Ces reliefs comprennent, de préférence, des dentures dont les dents s'étendent selon une direction globalement transversale par rapport à un axe longitudinal de la partie tubulaire. En variante, ces reliefs peuvent être des pointes, des rainures croisées, un moletage ou autre. On peut en outre prévoir que la dureté de ces reliefs est supérieure à la dureté de surface de la tige et/ou de la partie tubulaire, au moins au niveau des zones de ces tige et partie tubulaire qui sont destinées à être en contact avec ces reliefs. Cet aspect de l'invention permet d'augmenter le coefficient de frottement entre la barrette et la tige et/ou entre la barrette et la partie tubulaire par micro-incrustation des reliefs dans les surfaces de la tige et de la partie tubulaire. On peut ainsi transmettre de fortes charges au moyen du mécanisme de l'invention. Les moyens d'immobilisation comprennent un étrier monté sur le fourreau et/ou la partie tubulaire, ainsi qu'une vis apte à exercer sur l' étrier, à travers une ouverture ménagée dans le fourreau, un effort de blocage de la tige, cet effort étant dirigé selon une direction globalement transversale par rapport à un axe longitudinal de la partie tubulaire. L'invention concerne également un métier à tisser équipé d'un mécanisme de formation de la foule tel que décrit ci-dessus. Un tel métier est plus facile à installer et à faire fonctionner que ceux de l'état de la technique. En particulier, le réglage du mécanisme de formation de la foule est facilité. L' invention sera mieux comprise et d' autres avantages de celle-ci apparaîtront plus clairement à la lumière de la description qui va suivre d'un mode de réalisation d'un mécanisme conforme à son principe, donnée uniquement à titre d'exemple et faite en référence aux dessins annexés dans lesquels : - la figure 1 est une représentation schématique de principe d'un métier à tisser conforme à l'invention ; la figure 2 est une coupe longitudinale de principe d'une des bielles du métier de la figure 1 ; - la figure 3 est une vue analogue à la figure 2 et représente la bielle en cours de montage ; - la figure 4 est une vue en perspective éclatée d'une partie de la bielle des figures 2 et 3. A la figure 1, une ratière 1 est destinée à entraîner plusieurs cadres de lisses d'un métier à tisser M, un seul cadre de lisses étant représenté avec la référence 2. Le cadre 2 est entraîné avec un mouvement vertical oscillant Fi. Pour ce faire, un bras d' actionnement la de la ratière 1 est attelé, par une bielle 3 orientée obliquement, à un premier levier oscillant 4 lui-même relié par une bielle 3' à un second levier oscillant 4' . Les deux leviers 4 et 4' sont articulés respectivement autour d'axes 5 et 5' fixes par rapport au bâti 6 du métier. Les leviers 4 et 4' sont chacun reliés au cadre 2 par des bielles 3' ' . II est prévu autant de bras la et d'ensembles de bielles 3, 3' et 3'' et de leviers 4 et 4' que de cadres de lisses à entraîner. Une bielle 3'' est représentée sur les figures 2 à 4 et comprend une partie tubulaire 31 destinée à recevoir dans son volume intérieur V3χ une tige 32 appartenant à une pièce allongée 33 qui définit un œillet 34 d'attelage au cadre 2. La partie 31 définit quant à elle un œillet 35 d'attelage de la bielle 3 sur le levier 4. La bielle 3'' est réglable en longueur et démontable. Un fourreau 40 est destiné à être introduit dans la zone d'extrémité V 3ι du volume V3χ, c'est-à-dire la partie de ce volume la plus proche de l'extrémité 36 de la partie 31 opposée à l'œillet 35, extrémité par laquelle la tige 32 pénètre dans le volume V31. Le fourreau 40 est réalisé par injection de matériau synthétique, notamment de polyamide ou de polyacétal, et présente de ce fait une certaine élasticité. Ce fourreau est monobloc et son corps principal 41 définit une ouverture allongée et traversante dont les dimensions transversales sont adaptées à la section transversale de la tige 32 et permettent le guidage à jeu réduit en translation de cette tige lors de son introduction dans cette ouverture, alors que le fourreau 40 est monté dans la partie 31. Le volume interne V41 de l'ouverture centrale du corpsThe invention relates to a crowd formation mechanism for a weaving loom. It relates, in particular, to the pulling mechanisms in which connecting rods are used to transmit to heald frames a movement generated by a dobby or an armor mechanism. The invention also relates to a weaving loom equipped with a mechanism of the aforementioned type. In the field of crowd training on weaving looms, it is known to use connecting rods which ensure the coupling of the movable actuating members with heald frames with vertical displacement mounted on the loom. It is known, for example from FR-A-2 836 488, that a force transmission rod can comprise a tubular part in which is engaged a nozzle provided with a grommet for coupling to an oscillating lever or an arm drive. To take into account the numerous installation configurations of the crowd formation mechanisms, it is also known to provide rods adjustable in length, with a part carrying an eyelet and forming a rod intended to be introduced and locked inside. a tubular part, thanks to a screw cooperating with a captive nut in the tubular part and exerting on the rod a pressure force against a bar also disposed in the rod. This approach requires to provide retaining means, inside the end of the tubular part, both for the nut and for the bar for receiving the support force. Such an approach also requires providing means for guiding the rod to avoid parasitic movements in a transverse direction. perpendicular to that according to which is applied the immobilization force obtained by means of the nut. These constraints induce an elaborate construction for the end of the tubular part of the connecting rod, which increases its cost price without the precision obtained being, in practice, satisfactory. In addition, these constructive arrangements can hinder the total introduction of the rod into the tubular part, which means that the minimum length of the connecting rod cannot be reduced below a limit value. It is to these drawbacks that the invention more particularly intends to remedy by proposing a new shedding mechanism, the rod (s) of which can be easily adjusted in length according to the configuration of the loom, while its cost remains economic and that the precision of the length adjustment of the connecting rods and its reliability comply with the requirements of the technical field and allow the loom to operate at high speed. In this spirit, the invention relates to a shedding mechanism for a loom, this mechanism comprising at least one rod adjustable in length and / or removable comprising a first part provided with a rod capable of sliding in a tubular part , as well as means for immobilizing this rod in position in this tubular part, characterized in that this connecting rod is equipped with a sheath whose internal volume forms a housing for receiving and centering the rod relative to the part tubular, this sheath being disposed inside this tubular part and ensuring the maintenance in position relative to this tubular part of at least one of the means for immobilizing the rod in position in the tubular part. Thanks to the invention, the sheath which is introduced into the end of the tubular part of the connecting rod performs several functions, namely the centering of the rod relative to the tubular part and the positioning of one or more means of immobilization, while the tubular part is smooth and devoid of reliefs, which greatly facilitates its manufacture. According to advantageous but not compulsory aspects, a shedding mechanism can incorporate one or more of the following characteristics taken in any technically admissible combination: The sheath is at least partially elastically deformable. - The sleeve carries or forms at least one centering member relative to the inner surface of the tubular part. This member is advantageously constituted by an elastically deformable and integral piece with a part of the sheath forming the aforementioned housing for receiving and centering the rod, this tab being intended to come into abutment against the internal surface of the tubular part. - The sheath is made of synthetic material, preferably injected, in particular of injected plastic. - The aforementioned immobilization means comprise a bar immobilized by the sheath in the tubular part, by cooperation of shapes, this bar being designed to receive the rod in support. In this case, the face of this bar intended to receive the bearing rod as well as the face of this bar facing the interior surface of the tubular part are provided with reliefs intended to increase the adhesion between this bar and the rod, d on the one hand, and the tubular part on the other. These reliefs preferably include toothing whose teeth extend in a generally transverse direction relative to a longitudinal axis of the tubular part. As a variant, these reliefs can be points, crossed grooves, knurling or the like. It can also be provided that the hardness of these reliefs is greater than the surface hardness of the rod and / or of the tubular part, at least at the level of the zones of these rod and tubular part which are intended to be in contact with these landforms. This aspect of the invention makes it possible to increase the coefficient of friction between the bar and the rod and / or between the bar and the tubular part by micro-incrustation of the reliefs in the surfaces of the rod and of the tubular part. It is thus possible to transmit high loads by means of the mechanism of the invention. The immobilization means comprise a stirrup mounted on the sheath and / or the tubular part, as well as a screw capable of exerting on the stirrup, through an opening made in the sheath, a force for locking the rod, this force being directed in a generally transverse direction relative to a longitudinal axis of the tubular part. The invention also relates to a weaving loom equipped with a shedding mechanism as described above. Such a loom is easier to install and operate than those of the prior art. In particular, the adjustment of the crowd formation mechanism is facilitated. The invention will be better understood and other advantages thereof will appear more clearly in the light of the following description of an embodiment of a mechanism in accordance with its principle, given solely by way of example and made with reference to the accompanying drawings in which: - Figure 1 is a schematic representation of the principle of a weaving loom according to the invention; Figure 2 is a longitudinal section in principle of one of the connecting rods of the trade of Figure 1; - Figure 3 is a view similar to Figure 2 and shows the connecting rod during assembly; - Figure 4 is an exploded perspective view of part of the connecting rod of Figures 2 and 3. In Figure 1, a dobby 1 is intended to drive several heald frames of a loom M, a single frame stringers being shown with the reference 2. The frame 2 is driven with an oscillating vertical movement Fi. To do this, an actuating arm 1a of the dobby 1 is coupled, by a connecting rod 3 oriented obliquely, to a first oscillating lever 4 itself connected by a connecting rod 3 'to a second oscillating lever 4'. The two levers 4 and 4 'are articulated respectively around axes 5 and 5' fixed relative to the frame 6 of the loom. The levers 4 and 4 'are each connected to the frame 2 by 3''connecting rods. There are as many arms 1a and sets of connecting rods 3, 3 'and 3''and levers 4 and 4' as heald frames to be driven. A connecting rod 3 '' is shown in Figures 2 to 4 and comprises a tubular part 31 intended to receive in its internal volume V 3 χ a rod 32 belonging to an elongated part 33 which defines an eyelet 34 for coupling to the frame 2. Part 31 defines an eye 35 for coupling the connecting rod 3 to the lever 4. The connecting rod 3 '' is adjustable in length and removable. A sheath 40 is intended to be introduced into the end zone V 3 ι of the volume V 3 χ, that is to say the part of this volume closest to the end 36 of the part 31 opposite to the eyelet 35, end by which the rod 32 enters the volume V 31 . The sheath 40 is produced by injection of synthetic material, in particular polyamide or polyacetal, and therefore has a certain elasticity. This sheath is in one piece and its main body 41 defines an elongated and through opening, the transverse dimensions of which are adapted to the cross section of the rod 32 and allow the reduced clearance guide in translation of this rod when it is introduced into this opening, then that the sleeve 40 is mounted in part 31. The internal volume V 41 of the central opening of the body
41 constitue un logement de réception et de guidage de la tige 32, lors de sa mise en place et postérieurement à cette mise en place. Le fourreau 40 est également pourvu d'une collerette41 constitutes a housing for receiving and guiding the rod 32, during its positioning and after this positioning. The sleeve 40 is also provided with a collar
42 destinée à venir en appui contre l'extrémité 36 de la partie 31 afin de limiter le mouvement d'introduction du fourreau 40 dans le volume V3ι, dans le sens de la flèche F2. La partie 31 est à section transversale globalement rectangulaire et l'on note 311 et 312 ses grands côtés, 313 et 314 ses petits côtés. Les dimensions transversales du fourreau 40 sont prévues pour permettre un centrage de ce fourreau par appui contre la surface interne 37 de la partie 31. Pour ce faire, le fourreau 40 est équipé de deux pattes élastiquement déformables 43 et 44 monoblocs avec le corps 41 et prévues pour venir respectivement en appui contre les petits côtés 313 et 314, ce qui permet de conserver globalement parallèle l'axe médian X4ι du logement V41 avec l'axe longitudinal X3ι-X'3ι de la partie 31. La largeur l4o du fourreau 40 est sensiblement égale à la distance d31 entre les grands côtés 311 et 312, de telle sorte que le fourreau est maintenu latéralement en appui contre les faces internes de ces côtés lorsqu'il est introduit dans la partie 31. L'ajustement précis en largeur du fourreau 40 dans le volume V3ι est obtenu grâce à quatre coins obliques par rapport à l'axe X4ι, divergents vers la collerette 42 et répartis deux par deux sur les faces latérales du corps 41 et dont deux sont visibles avec la référence 47 sur la face latérale 41a du corps 41 tournée vers l'observateur à la figure 4. Le fourreau 40 est également pourvu de deux ouvertures 45 et 46 destinée à être respectivement tournées vers les petits côtés 313 et 314 lorsque le fourreau 40 est en place dans la partie 31. Un étrier 50 est rapporté sur le fourreau 40 et comprend une première branche 51 destinée à venir en appui sur l'extérieur du côté 313 lorsque le fourreau est en place dans la partie 31. L' étrier 50 comprend également une seconde branche 52 qui s'étend globalement selon une direction parallèle à l'axe X4ι et se termine par un retour 53 globalement perpendiculaire à la branche 52. Lorsque 1' étrier 50 est en place, sa branche 52 s'étend au niveau de l'ouverture 45 et son retour 53 est dirigé vers le côté 313. Un écrou rectangulaire 60 est disposé entre la branche 52 et le côté 313 et reçoit la tige 61 d'une vis 62 qui traverse un perçage 38 ménagé dans le côté 313. Ainsi, le vissage de la vis 62 dans le taraudage 63 de l' écrou 60 permet de contrôler la position de cette vis selon une direction Y-Y' perpendiculaire à l'axe X-X' et parallèle aux côtés 311 et 312. Ceci permet d'exercer sur la branche 52 un effort de poussée F3 dirigé vers le côté 314, cet effort étant transmis à la tige 32 lorsqu'elle est engagée dans le volume V4χ. Une barrette 70 est disposée au niveau de l'ouverture 46 et l'on note 71 sa face orientée vers le volume V41 et 72 sa face orientée vers le côté 314. Les faces 71 et 72 sont parallèles et pourvues de dentures 71a, respectivement 72a, dont la dureté est supérieure à la dureté superficielle de la surface 37, au moins au niveau de la zone du côté 314 la plus proche de l'extrémité 36, d'une part, et de la surface de la tige 32, d'autre part. Les dents des dentures 71a et 72a s'étendent selon une direction A-A' perpendiculaire à l'axe Xι-X'3ι et à la direction Y-Y' . La barrette 70 est pourvue de deux talons 73 par lesquels elle peut venir en appui contre des talons 48 et 49 formés par le fourreau 40, de telle sorte que la barrette 70 ne peut pas passer à travers l'ouverture 46, alors même que sa surface 71 est exposée à travers l'ouverture 46 et en direction du volume V4ι dans la configuration de la figure 3, ce qui lui permet de recevoir en appui la tige 32 sous l'effet de l'effort F3. Ainsi, le volume V4i constitue un logement de réception de la tige 32, alors que les éléments 50, 60, 62 et 70 permettent d'exercer sur cette tige l'effort d'immobilisation F3 exercé selon la direction Y-Y'. Sous l'effet de l'effort F3, la tige 32 est fermement plaquée contre la denture 71a de la barrette 70, alors que la denture 72a est fermement plaquée contre le côté 314 de la partie 31. Compte tenu des duretés relatives de ces dentures par rapport aux duretés superficielles des pièces 31 et 32, il se produit des micro-incrustations des dents des dentures dans les parties en regard, ce qui permet d'augmenter sensiblement le coefficient de frottement entre les pièces 32 et 70, d'une part, 70 et 31, d'autre part, selon la direction longitudinale des pièces 31 et 32 et ce, d'autant plus que la direction A-A' est perpendiculaire à l'axe X31- X'31. On peut cependant obtenir de bons résultats en remplaçant les dentures 71a et/ou 72a par des dentures obliques ou croisées, par un moletage ou par des pointes. Les pattes 43 et 44 et les coins 47 permettent de centrer le fourreau 40 dans le volume V31. Ils peuvent se déformer élastiquement pour tenir compte d'un éventuel défaut d'alignement de l'axe central X32- '32 de la tige 32 avec l'axe X3ι-X'3ι. La longueur Li de l'ouverture du corps 41 est suffisante pour guider et soutenir efficacement la tige 32 à la fois lors de son mouvement d' introduction dans le sens de la flèche F4 et lorsqu'elle est immobilisée par l'effort F3. En pratique, cette longueur Li est au moins supérieure à la plus grande dimension de l' écrou 60 ou de la barrette 70. Le montage et le réglage en longueur de la bielle 3' ' ont lieu en insérant partiellement la barrette 70 dans l'ouverture 46 d'une part, alors que l' étrier 50 est accroché sur le fourreau 40 et que l' écrou 60 est en appui sur la branche 52. Les éléments 50 et 60 sont maintenus en position grâce à l'accrochage de la branche 51 sur le fourreau 40. La barrette 70 ne risque pas de migrer vers le volume V4χ car elle est retenue par la coopération des parties 48, 49 et 73. Ensuite, le fourreau 40 ainsi équipé est introduit dans la partie 31, dans le sens de la flèche F2. Puis la vis 62 est amenée en prise avec le taraudage 63, ce qui rend imperdable les éléments 40, 50, 60 et 70. Ensuite, la tige 32 est introduite dans le fourreau 40 et la partie 31 dans le sens de la flèche F jusqu'à obtenir la longueur désirée pour la bielle 3' ' dont la vis 62 est alors serrée pour exercer l'effort F3 d'immobilisation. En desserrant la vis 62 il est possible de modifier ultérieurement la longueur de la bielle ou de la démonter. La partie tubulaire 31 est particulièrement simple à réaliser, donc économique. Les autres bielles 3 et 3' du métier M peuvent êtres prévues selon le même principe que les bielles 3''. En variante, certaines de ces bielles peuvent ne pas être réglables en longueur ou démontable. L'invention n'est pas limitée aux métiers à ratière positive mais s'applique aux métiers à ratière négative, avec des bielles situées au-dessus des cadres, et au métiers à mécanique à cames. 42 intended to come into abutment against the end 36 of the part 31 in order to limit the movement of introduction of the sheath 40 into the volume V 3 ι, in the direction of the arrow F 2 . Part 31 has a generally rectangular cross section and there are 311 and 312 its long sides, 313 and 314 its short sides. The transverse dimensions of the sheath 40 are provided to allow centering of this sheath by pressing against the internal surface 37 of the part 31. To do this, the sheath 40 is equipped with two elastically deformable lugs 43 and 44 integral with the body 41 and intended to come into abutment respectively against the short sides 313 and 314, which makes it possible to keep overall parallel the median axis X 4 ι of the housing V 41 with the longitudinal axis X 3 ι-X ' 3 ι of the part 31. The width l 4 o of the sheath 40 is substantially equal to the distance d 31 between the long sides 311 and 312, so that the sheath is held laterally in abutment against the internal faces of these sides when it is introduced into part 31. The precise adjustment in width of the sheath 40 in the volume V 3 ι is obtained by means of four oblique corners with respect to the axis X 4 ι, divergent towards the flange 42 and distributed two by two on the lateral faces of the body 41 and two of which are visible with the reference 47 on the lateral face 41a of the body 41 facing the observer in FIG. 4. The sheath 40 is also provided with two openings 45 and 46 intended to be respectively turned towards the short sides 313 and 314 when the sheath 40 is in place in the part 31. A stirrup 50 is attached to the sheath 40 and comprises a first branch 51 intended to come to bear on outside the side 313 when the sheath is in place in the part 31. The stirrup 50 also includes a second branch 52 which extends generally in a direction parallel to the axis X 4 ι and ends in a re tower 53 generally perpendicular to the branch 52. When the stirrup 50 is in place, its branch 52 extends at the opening 45 and its return 53 is directed towards the side 313. A rectangular nut 60 is disposed between the branch 52 and the side 313 and receives the rod 61 of a screw 62 which passes through a bore 38 formed in the side 313. Thus, the screwing of the screw 62 in the thread 63 of the nut 60 makes it possible to control the position of this screw in a direction YY 'perpendicular to the axis XX' and parallel to the sides 311 and 312. This allows to exert on the branch 52 a thrust force F 3 directed towards the side 314, this force being transmitted to the rod 32 when it is engaged in volume V 4 χ. A bar 70 is arranged at the opening 46 and there is noted 71 its face oriented towards the volume V 41 and 72 its face oriented towards the side 314. The faces 71 and 72 are parallel and provided with teeth 71a, respectively 72a, the hardness of which is greater than the surface hardness of the surface 37, at least at the zone on the side 314 closest to the end 36, on the one hand, and the surface of the rod 32, d 'somewhere else. The teeth of the teeth 71a and 72a extend in a direction AA 'perpendicular to the axis Xι-X' 3 ι and to the direction YY '. The bar 70 is provided with two heels 73 by which it can bear against heels 48 and 49 formed by the sheath 40, so that the bar 70 cannot pass through the opening 46, even when its surface 71 is exposed through the opening 46 and in the direction of the volume V 4 ι in the configuration of FIG. 3, which allows it to receive the rod 32 in support under the effect of the force F 3 . Thus, the volume V 4i constitutes a housing for receiving the rod 32, while the elements 50, 60, 62 and 70 make it possible to exert on this rod the immobilizing force F 3 exerted in the direction Y-Y ' . Under the effect of the force F3, the rod 32 is firmly pressed against the toothing 71a of the bar 70, while the toothing 72a is firmly pressed against the side 314 of the part 31. Taking into account the relative hardness of these toothing compared to the surface hardnesses of the parts 31 and 32, micro-incrustations of the teeth of the teeth occur in the facing parts, which makes it possible to significantly increase the coefficient of friction between the parts 32 and 70, on the one hand , 70 and 31, on the other hand, in the longitudinal direction of the parts 31 and 32, all the more so as the direction AA ′ is perpendicular to axis X 31 - X '31 . However, good results can be obtained by replacing the toothing 71a and / or 72a by oblique or crossed toothing, by knurling or by spikes. The legs 43 and 44 and the corners 47 make it possible to center the sheath 40 in the volume V 3 1. They can deform elastically to take account of a possible misalignment of the central axis X 32 - '32 of the rod 32 with the axis X 3 ι-X ' 3 ι. The length L i of the opening of the body 41 is sufficient to effectively guide and support the rod 32 both during its introduction movement in the direction of the arrow F 4 and when it is immobilized by the force F 3 . In practice, this length L i is at least greater than the largest dimension of the nut 60 or of the bar 70. The assembly and length adjustment of the connecting rod 3 '' takes place by partially inserting the bar 70 into the opening 46 on the one hand, while the stirrup 50 is hooked on the sheath 40 and the nut 60 is in abutment on the branch 52. The elements 50 and 60 are held in position by hooking the branch 51 on the sheath 40. The bar 70 does not risk migrating to the volume V 4 χ because it is retained by the cooperation of the parts 48, 49 and 73. Then, the sheath 40 thus equipped is introduced into the part 31, in the direction of arrow F 2 . Then the screw 62 is brought into engagement with the internal thread 63, which makes the elements 40, 50, 60 and 70 captive. Then, the rod 32 is introduced into the sheath 40 and the part 31 in the direction of the arrow F until 'to obtain the desired length for the rod 3''whose screw 62 is then tightened to exert the force F 3 immobilization. By loosening the screw 62 it is possible to subsequently modify the length of the connecting rod or to disassemble it. The tubular part 31 is particularly simple to produce, therefore economical. The other rods 3 and 3 'of the loom M can be provided according to the same principle as the rods 3''. Alternatively, some of these connecting rods may not be adjustable in length or removable. The invention is not limited to trades with positive dobby but applies to trades with negative dobby, with connecting rods located above the frames, and to trades with mechanical cams.
