Description

On sait que dans les mécaniques d'armures du genre Verdol, il est possible de réaliser l'ensemble de chaque aiguille et de son butoir, en une seule pièce, de sorte que l'on supprime les guidages de ce dernier.We know that in the armor mechanics of the Verdol genre, it is possible to make all of each needle and its stopper, in one piece, so that the guides of the latter are eliminated.

De plus l'aiguille en une seule pièce peut être placée en précontrainte en direction du haut, de manière à permettre la suppression des ressorts des aiguillettes.In addition, the needle in one piece can be pre-stressed in the upward direction, so as to allow the removal of the needle springs.

Une telle solution limitant le nombre de pièces de l'ensemble permet d'en abaisser le prix de revient. Toutefois, lorsque l'on veut nettoyer l'ensemble constitué par les aiguillettes et leur guidage, il est nécessaire de sortir ledit ensemble isolément, et de le remettre en place en engageant chaque aiguille monobloc dans l'oeillet de l'aiguillette correspondante.Such a solution limiting the number of parts in the assembly makes it possible to lower the cost price. However, when it is wished to clean the assembly constituted by the needles and their guidance, it is necessary to take out the said assembly in isolation, and to put it back in place by engaging each monobloc needle in the eyelet of the corresponding needle.

On comprend aisément qu'une telle opération est délicate et coûteuse. On a donc pensé à simplifier les opérations de telle sorte qu'on puisse effectuer le démontage de l'ensemble des aiguillettes et de leur guidage en vue de procéder à son nettoyage, puis le remontage de cet ensemble sur la mécanique sans avoir d'opérations délicates à effectuer.It is easy to understand that such an operation is delicate and costly. We therefore thought of simplifying the operations so that we can carry out the disassembly of all the needles and their guide for cleaning, then reassembly of this assembly on the mechanics without having operations delicate to perform.

Pour que les opérations précitées s'effectuent facilement, on prévoit de placer des déflecteurs contre lesquels les aiguilles viennent buter lorsqu'on les enfile dans la mécanique, de sorte qu'elles sont déviées vers le haut, si bien qu'elles viennent se disposer entre deux oreilles latérales prévues sur les aiguillettes pour remplacer les boucles usuelles de celles-ci qui sont traversées par les aiguilles.For the above operations to be carried out easily, provision is made to place deflectors against which the needles abut when they are threaded in the mechanics, so that they are deflected upwards, so that they come to be arranged between two lateral ears provided on the needles to replace the usual loops thereof which are crossed by the needles.

Il est nécessaire que le bout des aiguilles qui doit être poussé ou non par le train de barres, traverse les perforations d'une plaque de guidage verticale. La lecture du papier perforé s'effectue dans la mécanique suivant l'invention par déplacement vertical de celui-ci en direction des aiguillettes. Ainsi en remplaçant le papier perforé par un carton sans trou, on peut soulever toutes les aiguillettes vers le haut afin d'amener les bouts libres des aiguilles en face des perforations de la plaque de guidage et la déplacer en direction des aiguillettes pour que les aiguilles s'engagent dans lesdites perforations. Enfin la coquille supportant le carton est abaissée de telle sorte que les aiguilles viennent prendre appui contre la partie inférieure des perforations de la plaque de guidage en restant précon-. traintes.It is necessary that the end of the needles which must be pushed or not by the train of bars, crosses the perforations of a vertical guide plate. The perforated paper is read in mechanics according to the invention by vertical displacement thereof in the direction of the needles. So by replacing the perforated paper with a cardboard without holes, we can lift all the needles upwards in order to bring the free ends of the needles opposite the perforations of the guide plate and move it in the direction of the needles so that the needles engage in said perforations. Finally the shell supporting the cardboard is lowered so that the needles come to bear against the lower part of the perforations of the guide plate while remaining prec - . treacherous.

Bien entendu la disposition suivant la présente invention permet l'échange très facile d'une aiguille. A cet effet après retrait de l'aiguille endommagée, on en enfile une nouvelle qui passe au-dessus de l'oreille de l'aiguillette considérée. Pour la faire pénétrer dans la perforation de la plaque de guidage il suffit de soulever l'ensemble des aiguillettes comme indiqué précédemment.Of course the arrangement according to the present invention allows very easy exchange of a needle. For this purpose after removal of the damaged needle, a new one is threaded which passes over the ear of the needle under consideration. To make it penetrate into the perforation of the guide plate, it suffices to lift all the needles as indicated above.

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer :

  • Fig. 1 représente schématiquement une mécanique d'armure comportant application des perfectionnements suivant l'invention. Cette mécanique a été réduite à sa plus simple expression, c'est-à-dire qu'elle ne comporte qu'un crochet, qu'une aiguille, et qu'une aiguillette.
  • Fig. 2 illustre en perspective les différentes pièces essentielles de la mécanique d'armure suivant l'invention.
  • Fig. 3 à 9 sont des vues schématiques des différentes phases de montage d'une mécanique d'armure conforme à l'invention.
The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing:
  • Fig. 1 schematically represents an armor mechanism comprising application of the improvements according to the invention. This mechanism has been reduced to its simplest expression, that is to say that it has only one hook, one needle, and one needle.
  • Fig. 2 illustrates in perspective the various essential parts of the armor mechanics according to the invention.
  • Fig. 3 to 9 are schematic views of the different stages of mounting an armor mechanism according to the invention.

On rappellera brièvement qu'une mécanique d'armure comporte des crochets 1 (Fig. 1) dont l'extrémité inférieure est solidaire d'une lisse 2 dans l'oeillet 2a de laquelle passe un fil de chaîne 3 qui est déplacé vers le haut ou le bas pour permettre le passage d'une duite.It will be recalled briefly that an armor mechanism comprises hooks 1 (FIG. 1), the lower end of which is integral with a heddle 2 in the eyelet 2a from which passes a warp wire 3 which is moved upwards or the bottom to allow the passage of a pick.

Le crochet est élevé ou abaissé par un cadre de griffes 4 dont les lames 4a saisissent ou non le crochet suivant que celui-ci est à sa position normale ou à une position décalée engendrée par un déplacement axial d'une aiguille 5 poussée par une barre 6 à l'encontre de la réaction du ressort 7. Ce déplacement axial de l'aiguille 5 qui est appelé la "presse" dans la technique du tissage se produit en fonction de la position d'une aiguillette 8 dont l'extrémi- té inférieure coopère avec un papier perforé 9. Dans l'exemple illustré, l'aiguille 5 est d'une seule pièce, ses deux extrémités étant guidées dans des perforations de deux plaques de guidage 10, respectivement 11.The hook is raised or lowered by a frame of claws 4 whose blades 4a grasp or not the hook depending on whether the latter is in its normal position or in an offset position generated by an axial displacement of a needle 5 pushed by a bar 6 against the reaction of the spring 7. This axial displacement of the needle 5 which is called the "press" in the weaving technique occurs as a function of the position of a needle 8 whose end - lower cooperates with a perforated paper 9. In the example illustrated, the needle 5 is in one piece, its two ends being guided in the perforations of two guide plates 10, 11 respectively.

Les aiguillettes 8 sont chargées élastiquement en direction du bas par l'intermédiaire de l'aiguille 5 qui possède une certaine élasticité du fait qu'elle est précontrainte en direction du haut comme on l'expliquera mieux plus loin. Au repos, elles sont en appui par l'intermédiaire d'un épaulement 8a contre un panneau horizontal 12 dont elles traversent les perforations.The needles 8 are loaded elastically in the direction of the bottom by means of the needle 5 which has a certain elasticity because it is prestressed in the direction of the top as will be explained better below. At rest, they are supported by means of a shoulder 8a against a horizontal panel 12 of which they pass through the perforations.

Lorsqu'on veut faire lire un papier perforé, celui-ci.est élevé en direction du panneau 12. Lorsque les aiguillettes butent sur ce papier à un endroit où il n'existe aucune perforation, elles sont remontées de manière à amener le bout libre 5a.de l'aiguille 5 en face de la barre 6. Au contraire si l'aiguillette tombe en face d'un trou, elle n'est pas actionnée et la barre 6 correspondante se déplace en direction du crochet 1 sans agir sur l'aiguille.When you want to read a perforated paper, it is raised towards the panel 12. When the needles abut on this paper at a place where there is no perforation, they are raised so as to bring the free end 5a. Of the needle 5 opposite the bar 6. On the contrary, if the needle falls in front of a hole, it is not actuated and the corresponding bar 6 moves in the direction of the hook 1 without acting on the 'needle.

Chacune des aiguil lettes est avantageusement réalisée sous la forme d'un profilé plat dont la partie inférieure est solidaire d'une queue cylindrique 8b à faible diamètre, tandis qu'elle comporte une oreille latérale 8c dont l'arête supérieure est pourvue d'une encoche concave 8d.Each of the sharp needles is advantageously produced in the form of a flat profile, the lower part of which is secured to a cylindrical tail 8b of small diameter, while it comprises a lateral ear 8c, the upper edge of which is provided with a concave notch 8d.

Pour effectuer la précontraite de chaque aiguille 5, la mécanique suivant l'invention est pourvue d'une grille dont les barreaux 13 constituent un plan incliné pour des raisons qu'on expliquera mieux plus loin.To carry out the prestressing of each needle 5, the mechanism according to the invention is provided with a grid, the bars 13 of which constitute an inclined plane for reasons which will be explained better below.

En fig. 2 on a représenté une aiguille 5 en position de repos, son bout libre 5a se trouvant en dessous de la barre 6, tandis que la précontrainte de ladite aiguille est maintenue par coopération avec la partie inférieure de la perforation lla de la plaque de guidage 11.In fig. 2 a needle 5 is shown in the rest position, its free end 5a being below the bar 6, while the preload of said needle is maintained by cooperation with the lower part of the perforation 11a of the guide plate 11 .

Pour effectuer la mise en place de chaque aiguille, on l'introduit dans la mécanique à partir du guidage correspondant de la plaque 10, de telle sorte que son bout libre 5a vient buter contre le barreau incliné 13 qui, jouant le rôle de déflecteur, courbe l'aiguille en direction du haut lorsqu'on continue de lui faire subir un déplacement axial (fig. 3 et 4).To carry out the positioning of each needle, it is introduced into the mechanics from the corresponding guide of the plate 10, so that its free end 5a abuts against the inclined bar 13 which, playing the role of deflector, bends the needle upwards when it continues to undergo an axial displacement (fig. 3 and 4).

L'inclinaison du barreau 13 est telle que lorsque le bout 5a arrive à proximité de l'aiguillette correspondante 8 il passe au-dessus de son oreille latérale 8c (fig. 5). On observe sur cette figure la position de repos des aiguillettes dans laquelle l'épaulement 8a de chacune d'elles est en appui contre le panneau 12.The inclination of the bar 13 is such that when the tip 5a comes close to the corresponding needle 8 it passes over its lateral ear 8c (fig. 5). This figure shows the rest position of the needles in which the shoulder 8a of each of them bears against the panel 12.

Si l'ensemble constitué par les aiguillettes et leur organe de guidage se trouve en place comme illustré en fig. 6, la poursuite du déplacement axial de l'aiguille provoque sa coopération avec l'encoche 8d de l'oreille 8c, si bien qu'elle est courbée davantage vers le haut.If the assembly constituted by the needles and their guide member is in place as illustrated in FIG. 6, the continued axial movement of the needle causes its cooperation with the notch 8d of the ear 8c, so that it is bent more upwards.

A l'inverse, les aiguilles étant en place cambrées vers le haut par les barreaux 13, il est possible d'installer dans la mécanique l'ensemble des aiguillettes 8 car leurs oreilles latérales 8c viennent respectivement se placer en dessous de l'aiguille 5 correspondante. Un déplacement ultérieur des aiguilles en direction des barreaux 13 provoque le cambrage supplémentaire vers le haut des aiguilles 5 comme illustré en fig. 5.Conversely, the needles being in place arched upwards by the bars 13, it is possible to install in the mechanics all of the needles 8 because their lateral ears 8c are respectively placed in below the corresponding needle 5. A subsequent movement of the needles in the direction of the bars 13 causes the additional bending upward of the needles 5 as illustrated in FIG. 5.

Lorsqu'on arrive à cette phase de montage, on place en dessous des aiguillettes 8, un carton non perforé 14-sur la coquille usuelle du mécanisme qui permet le glissement du papier perforé.When we arrive at this assembly phase, we place underneath the needles 8, a non-perforated cardboard 14-on the usual shell of the mechanism which allows the sliding of the perforated paper.

Cette coquille est prévue déplaçable alternativement en direction du haut et du bas, car la sélection s'effectue dans une mécanique suivant l'invention, par déplacement du papier en direction des aiguillettes. Du fait que ce dernier a été remplacé par un carton non perforé, un déplacement vers le haut de la coquille 15 entraine l'élévation de toutes les aiguillettes si bien qu'elles provoquent un cambrage supplémentaire vers le haut des aiguilles 5 (fig. 7).This shell is provided that can be moved alternately in the upward and downward direction, since the selection is made in a mechanism according to the invention, by displacement of the paper in the direction of the needles. Since the latter has been replaced by an unperforated cardboard, an upward movement of the shell 15 causes all of the needles to rise so that they cause additional upward arching of the needles 5 (FIG. 7 ).

Le bout libre 5a vient alors en vis-à-vis des perforations lla de la plaque de guidage 11. Là encore, il existe deux possibilités. Dans la première, la plaque de guidage est en place ainsi que l'ensemble des aiguillettes, et l'élévation de la coquille 15 s'effectue avant que le déplacement axial des aiguilles soit terminé.The free end 5a then comes opposite the perforations 11a of the guide plate 11. Again, there are two possibilities. In the first, the guide plate is in place as well as all of the needles, and the raising of the shell 15 takes place before the axial displacement of the needles is completed.

Suivant l'autre hypothèse les aiguilles sont mises en place avant les aiguillettes, et dans ce cas, on fait subir à la plaque de guidage 11, une translation vers la gauche, en fig. 6 afin d'engager les aiguilles dans ses perforations lla.According to the other hypothesis, the needles are put in place before the needles, and in this case, the guide plate 11 is subjected to a translation to the left, in FIG. 6 in order to engage the needles in its perforations lla.

La fig. 8 illustre la position des différents éléments d'une mécanique d'armure suivant l'invention lorsque les aiguillettes 8 sont en position de repos ou qu'elles tombent en face d'une perforation du papier 9. On observe qu'à cette position de lecture, le bout 5a de l'aiguille 5 est hors de portée de la barre 6 qui à chaque sélection se déplace vers la gauche.Fig. 8 illustrates the position of the various elements of an armor mechanism according to the invention when the needles 8 are in the rest position or when they fall in front of a perforation in the paper 9. It is observed that at this position of reading, the tip 5a of the needle 5 is out of range of the bar 6 which at each selection is moves to the left.

Au contraire, dans la position illustrée en fig. 9, l'aiguillette 8 ne tombe pas en face d'un trou du papier 9, si bien qu'elle est remontée de sorte que le bout libre 5a de l'aiguille 5 vient en face de la barre 6 dont le déplacement entraînera une translation de l'aiguille 5 et la "presse" du crochet 1 (fig. 1).On the contrary, in the position illustrated in fig. 9, the needle 8 does not fall in front of a hole in the paper 9, so that it is raised so that the free end 5a of the needle 5 comes in front of the bar 6, the displacement of which will cause a translation of the needle 5 and the "press" of the hook 1 (fig. 1).

On observe qu'en fig. 8, c'est la plaque de guidage 11 qui détermine la position de l'aiguille du fait que cette dernière se trouve en appui contre la partie basse de la perforation lla correspondante.We observe that in fig. 8, it is the guide plate 11 which determines the position of the needle because the latter is in abutment against the lower part of the corresponding perforation 11a.

Grâce à cette disposition, le panneau 12 n'est pas chargé en direction du bas, puisque les oreilles 8c des aiguillettes 8 sont situées très légèrement en dessous de l'aiguille 5. Au contraire, lorsque l'aiguillette est élevée par le papier, elle coopère pratiquement tout de suite avec l'aiguille 5, par l'intermédiaire de son oreille, ladite aiguille constituant le moyen de rappel vers le bas de l'aiguillette quand le papier est redescendu.Thanks to this arrangement, the panel 12 is not loaded in the downward direction, since the ears 8c of the needles 8 are located very slightly below the needle 5. On the contrary, when the needle is raised by the paper, it cooperates almost immediately with the needle 5, via its ear, said needle constituting the return means towards the bottom of the needle when the paper is lowered.

En dehors des facilités de montage de l'ensemble des ; aiguillettes et de la plaque de guidage des aiguilles, lorsque celles-ci restent en place, l'on peut, comme on l'a expliqué plus haut, effectuer aisément le remplacement d'une ou plusieurs aiguilles sans déplacer les autres éléments de la mécanique.Apart from the assembly facilities of all; needles and the needle guide plate, when they remain in place, it is possible, as explained above, to easily replace one or more needles without moving the other elements of the mechanism .
