Description

La présente invention a trait aux cadres de lisses qui sont montés sur les métiers à tisser et qui sont reliés à une ratière ou autre mécanique pour la formation de la foule, en vue de la réalisation d'un tissu con­formément à l'armature désirée.The present invention relates to heald frames which are mounted on the looms and which are connected to a dobby or other mechanical for the formation of the crowd, for the production of a fabric in accordance with the desired reinforcement.

On sait que ces cadres sont constitués par l'assemblage de quatre élé­ments séparés, à savoir deux traverses horizontales superposées et deux montants latéraux, le bord desdites traverses qui est tourné vers l'intérieur étant équipé d'un rail pour la fixation des crochets prévus aux extrémités des lisses guide-fil. Afin de faciliter la mise en place de l'ensemble de ces lisses, l'assemblage montant-traverse aménagé au niveau de chacun des angles du cadre est établi sous forme aisément démontable et la présente invention se fonde justement sur l'observation que le choix du mode d'assemblage est plus délicat qu'il peut paraître à première vue.We know that these frames are constituted by the assembly of four separate elements, namely two superimposed horizontal crosspieces and two lateral uprights, the edge of said crosspieces which is turned inwards being equipped with a rail for fixing the hooks provided. at the ends of the thread guide bars. In order to facilitate the installation of all of these heddles, the upright-transom assembly arranged at each of the angles of the frame is established in easily removable form and the present invention is based precisely on the observation that the choice of the assembly method is more delicate than it may seem at first glance.

Certaines construction ont adopté un système d'asemblage permettant l'obtention d'une rigidité parfaite du cadre, mais un tel système fait le plus souvant intervenir un nombre relativement élevé de pièces sépa­rées et d'organes de fixation, en rendant ainsi fastidieuses les manoeu­vres de démontage et de remontage. A l'inverse, d'autres solutions pro­posées ont bien assuré une facilité opératoire remarquable, mais cet avantage est généralement acquis au détriment de la solidité.Certain constructions have adopted an assembly system allowing the perfect rigidity of the frame to be obtained, but such a system most often involves a relatively large number of separate parts and fixing members, thus making maneuvers tedious. disassembly and reassembly. Conversely, other solutions proposed have indeed provided remarkable ease of operation, but this advantage is generally acquired at the expense of solidity.

Dans le Brevet Europe N° 0189216 est décrit un système d'assemblage démontable dans lequel chaque montant comporte un nez qui fait latéra­lement saillie sur la paroi dudit montant tournée vers l'intérieur du cadre et dont les bords horizontaux forment portées propres à coopérer avec une pièce fixe et une lame de ressort, ces deux pièces étant reliées l'une à l'autre par une vis de serrage afin d'agir à la manière de mâchoires pour immobiliser le nez précité.In the European Patent N ° 0189216 is described a removable assembly system in which each upright has a nose which projects laterally on the wall of said upright turned towards the inside of the frame and whose horizontal edges form clean enough to cooperate with a fixed part and a leaf spring, these two parts being connected to each other by a clamping screw in order to act in the manner of jaws to immobilize the aforementioned nose.

On notera que si un tel agencement permet bien l'obtention de la simplicité de manoeuvre par suite de l'unicité de la vis assurant la fermeture des mâchoires, il comporte l'inconvénient d'appliquer aux montants du cadre des moments de flexion par suite du déport latéral du nez en saillie par rapport à l'axe vertical desdits montants.It will be noted that if such an arrangement makes it possible to obtain simplicity of maneuver as a result of the uniqueness of the screw ensuring the closing of the jaws, it has the disadvantage of applying bending moments to the uprights of the frame as a result. lateral offset of the projecting nose relative to the vertical axis of said uprights.

C'est à l'ensemble de ces inconvénients qu'entend remédier la présente invention, laquelle a pour objet le cadre de lisses tel que défini à la revendication 1.It is to all of these drawbacks that this present intends to remedy invention which relates to the heald frame as defined in claim 1.

En fait l'invention consiste à définir les portées contre lesquelles s'appliquent les mâchoires, par les bords d'au moins une ouverture pratiquée dans la paroi du montant qui fait face auxdites mâchoires, afin que ces portées se trouvent disposées dans l'axe du montant en vue d'éviter tout moment de flexion au niveau de celui-ci.In fact the invention consists in defining the bearing surfaces against which the jaws apply, by the edges of at least one opening made in the wall of the upright which faces said jaws, so that these bearing surfaces are arranged in the axis amount in order to avoid any bending moment at this level.

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 est une vue en perspective avec arrachements, illustrant l'agencement des pièces qui concourrent à l'assemblage situé au niveau de l'un des deux angles supérieurs d'un cadre de lisses éta­bli conformément à l'invention.
  • Fig. 2 est la vue de côté correspondanten, également avec arrache­ments.
  • Fig. 3 reproduit fig. 2 après assemblage du montant et de la traverse envisagée.
  • Fig. 4 illustre une variante de mise en oeuvre de 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 is a perspective view with parts broken away, illustrating the arrangement of the parts which contribute to the assembly situated at one of the two upper angles of a heald frame established in accordance with the invention.
  • Fig. 2 is the corresponding side view, also with cutouts.
  • Fig. 3 reproduced fig. 2 after assembly of the upright and the envisaged crosspiece.
  • Fig. 4 illustrates a variant implementation of the invention.

Sur ce dessin, la référence 1 désigne l'une des deux extrémités de la traverse horizontale supérieure du cadre considéré, laquelle traverse est formée, à la façon en soi connue, par un profilé creux raidi par des cloisons horizontales intérieures. Dans l'extrémité envisagée de cette traverse 1 est engagée une mâchoire fixe 2 pourvue d'un talon horizontal 2a immobilisé en place à l'aide des deux vis 3 qui assurent la fixation de l'oreille classique 4 (non représentée en fig. 1) destinée à l'amarrage de l'organe de tirage associé à la ratière.In this drawing, the reference 1 designates one of the two ends of the upper horizontal cross member of the frame in question, which cross member is formed, in the manner known per se, by a hollow profile stiffened by internal horizontal partitions. In the proposed end of this cross member 1 is engaged a fixed jaw 2 provided with a horizontal bead 2 has locked in place using the two screws 3 which ensure the fixing of the ear vector 4 (not shown in fig. 1) intended for mooring the pulling member associated with the dobby.

A l'opposé du talon 2a, la mâchoire 2 comporte un bec en saillie 2b propre à former mors de serrage, ainsi qu'on le comprendre mieux plus loin. A ce bec ou mors fixe 2b fait face un bec ou mors mobile 5a prévu en bout d'une mâchoire basculante 5 convenablement profilée et réunie à la mâchoire fixe 2 par une vis 6, comme illustré en fig. 2 et 3. Il con­vient d'observer que les mors 2b et 5a définissent entre eux un logement 2c qui présente en section un profil substantiellement trapézoïdal dont la petite base est tournée vers l'extérieur de l'extrémité considérée de la traverse 1.Opposite the heel 2 a , the jaw 2 has a protruding beak 2 b capable of forming a clamping jaw, as will be better understood below. At this spout or fixed jaw 2 b faces the mouthpiece or movable jaw 5 is provided at the end of a tilting jaw suitably profiled 5 and joined to the fixed jaw 2 by a screw 6, as illustrated in fig. 2 and 3. It should be observed that the jaws 2 b and 5 a define between them a housing 2 c which has in section a substantially trapezoidal profile whose small base is turned towards the outside of the considered end of the cross-member. 1.

Ce logement 2c est destiné à accueillir un organe d'asemblage 7a présen­tant le même profil trapézoïdal, lequel organe est solidaire de l'extré­mité supérieure du montant correspondant 7 du cadre de lisses. A cet effet ce montant 7, présentant en section un profil en forme de U, est découpé au niveau de son voile central, d'une ouverture 7b qui définit ainsi l'organe 7a sus-mentionnée, lequel comporte deux portées opposées 7c orientées obliquement pour coopérer avec les mors 2b et 5a.This housing 2 c is intended to accommodate an assembly member 7 a having the same trapezoidal profile, which member is integral with the upper end of the corresponding upright 7 of the heald frame. To this end, this upright 7, having a U-shaped profile in section, is cut at its central veil, with an opening 7b which thus defines the member 7 a mentioned above, which has two opposite bearing surfaces 7 c oriented obliquely to cooperate with jaws 2 b and 5 a .

On comprend dans ces conditions que lorsque la mâchoire mobile 5 a été amenée, après dévissage de la vis 6, à la position basse illustrée en fig. 1 et 2 pour laquelle elle repose contre une cloison 1a de la tra­verse 1, l'organe 7a est susceptible d'être introduit à l'intérieur du logement 2c moyennant le rapprochement du sommet du montant 7. Il suffit alors de manoeuvrer au vissage la vis 6 pour opérer le déplacement de la mâchoire mobile 5 vers le haut, le mors 5a venant refermer en quelque sorte la partie inférieure ouverte du logement trapézoïdal 2c de la mâchoire fixe 2.It is understood under these conditions that when the movable jaw 5 has been brought, after unscrewing the screw 6, to the low position illustrated in FIG. 1 and 2 for which it rests against a partition 1 a of the cross-member 1, the member 7 a is capable of being introduced inside the housing 2 c by bringing the top of the upright 7 closer together. It then suffices to maneuver when screwing the screw 6 to operate the displacement of the movable jaw 5 upward, the jaw 5 a somehow closing the open lower part of the trapezoidal housing 2 c of the fixed jaw 2.

Comme illustré en fig. 3, en fin de vissage l'organe 7a se trouve alors emprisonné à l'intérieur de ce logement 2c, la solidarisation ainsi as­surée présentant une rigidité parfaite par suite du profil substantiel­lement trapézoïdal dudit organe. On observera que l'assemblage mutuel est opéré dans l'axe du montant 7, sans aucun porte-à-faux et sans créa­tion de moment de flexion.As illustrated in fig. 3, at the end of screwing the member 7 a is then trapped inside this housing 2 c , the connection thus ensured having perfect rigidity as a result of the substantially trapezoidal profile of said member. It will be observed that the mutual assembly is operated in the axis of the upright 7, without any overhang and without creation of bending moment.

Bien évidemment, ce mode d'assemblage est avantageusement adopté au ni­veau des quatre angles du cadre de lisses qui, en dépît de sa résistance à la déformation, est susceptible d'être aisément démonté en vue du rem­placement des lisses guide-fil usuelles engagées sur un rail horizontal 8 prévu immédiatement au-dessous ou au-dessus du bord horizontal inté­rieur de chaque traverse 1. Les opérations de montage et de démontage sont simplifiées puisqu'elles ne nécessitent que la manoeuvre d'une seule vis 6 au niveau de chacun des angles du cadre de lisses, étant observé que cette vis est apte à être aisément rendue imperdable.Obviously, this method of assembly is advantageously adopted at the four angles of the heald frame which, despite its resistance to deformation, is capable of being easily disassembled with a view to replacing the usual yarn guide hoses engaged on a horizontal rail 8 provided immediately below or above the internal horizontal edge of each cross member 1. The assembly and disassembly operations are simplified since they only require the operation of a single screw 6 at each of the heald frame angles, being observed that this screw is able to be easily made captive.

Il va de soi que les montants 7 peuvent présenter en section tout profil désiré, le profil en U envisagé ci-dessus n'ayant été indiqué qu'à titre d'exemple.It goes without saying that the uprights 7 can have any desired profile in section, the U-profile envisaged above having been indicated only by way of example.

Dans la variante de réalisation illustrée en fig. 4, la mâchoire fixe, ici référencée 12, comporte un bec ou mors 12b tourné vers le haut, alors que le bec ou mors 15a de la mâchoire mobile 15 est tourné vers le bas. Les deux mâchoires 12 et 15 sont reliées l'une à l'autre par un ressort 19 qui tend à appliquer la mâchoire mobile 15 contre la cloison intérieure 1a de la traverse, et l'on comprend que les becs ou mors 12b et 15a sont propres à être introduits dans une ouverture 17b du montant 17 adjacent. La manoeuvre subséquente de la vis 16 au vissage assure l'écartement des deux mors précités qui viennent ainsi prendre appui contre les portées 17a formées par les deux bords opposés de l'ouverture 17b, en assurant de la sorte l'assemblege rigide des deux éléments 1 et 17 considérés du cadre de lisses.In the variant embodiment illustrated in FIG. 4, the fixed jaw, here referenced 12, comprises a beak or jaw 12 b turned upwards, while the beak or jaw 15 a of the movable jaw 15 is turned downwards. The two jaws 12 and 15 are connected to each other by a spring 19 which tends to apply the movable jaw 15 against the internal partition 1 a of the cross member, and it is understood that the beaks or jaws 12 b and 15 a are adapted to be introduced into an opening 17 b of the adjacent amount 17. The subsequent operation of the screw 16 when screwing ensures the spacing of the two aforementioned jaws which thus come to bear against the bearing surfaces 17 a formed by the two opposite edges of the opening 17 b , thereby ensuring the rigid assembly of the two elements 1 and 17 considered of the heald frame.
