Abstract
The invention relates to a weaving method that can be used to produce articles which have a warp made up of yarns directly using a weaving beam (2). The inventive method consists in: producing a warped chain comprising a total number of threads (1) that corresponds to the article to be made, said chain being produced directly on a beam (2) which can be adapted to the weaving loom; and, subsequently, using one such beam (2) to form a fabric in the conventional manner. Said method is characterised in that the sheet of warp (1) is subdivided into two basic sheets (1a, 1b) immediately after said sheet of warp (1) has been taken up from the storage beam (2) and before it is passed around the turning roll (3). The aforementioned basic sheets are subjected individually to a sizing or finishing treatment and are subsequently combined to form a single sheet after drying and before being passed around the turning roll (3).
Description
PROCEDE DE REALISATION D'UN TISSU CHAINE ET TRAME ET MACHINE A TISSER PERMETTANT SA MISE EN ŒUVRE. PROCESS FOR PRODUCING A CHAIN AND WEFT FABRIC AND WEAVING MACHINE FOR IMPLEMENTING IT.
La présente invention a trait à un procédé perfectionné permettant la réalisation d'un tissu chaîne et trame ; elle a trait également à une machine à tisser perfectionnée permettant la mise en œuvre d'un tel procédé.The present invention relates to an improved process for producing a warp and weft fabric; it also relates to an improved weaving machine allowing the implementation of such a process.
La réalisation de tissus chaîne et trame implique, avant l'opération de tissage proprement dite, que l'on doit procéder à une succession d'opérations de préparation tant en ce qui concerne les fils de trame que les fils de chaîne.The production of warp and weft fabrics implies, before the actual weaving operation, that a succession of preparation operations must be carried out both with regard to the weft threads and the warp threads.
Concernant les fils de trame qui, en général, sont stockés sous la forme d'une bobine, il est impératif qu'ils se dévident facilement et très régulièrement. Par suite, lors de l'opération de bobinage, notamment dans le cas de filés de fibres, on améliore les propriétés de glissement du fil en le recouvrant d'une fine pellicule lubrificatrice qui, pendant très longtemps, était obtenue par une opération de paraffinage ou encirage en faisant passer le fil au cours de l'opération de bobinage entre deux blocs de paraffine. Une telle opération relativement délicate à mettre en œuvre, est pratiquement abandonnée de nos jours et a été remplacée par des systèmes faisant appel à des lubrifiants liquides dits "ensimage".Concerning the weft threads which, in general, are stored in the form of a reel, it is imperative that they unwind easily and very regularly. As a result, during the winding operation, in particular in the case of fiber yarns, the sliding properties of the wire are improved by covering it with a thin lubricating film which, for a very long time, was obtained by a waxing operation. or drawing by passing the wire during the winding operation between two blocks of paraffin. Such a relatively delicate operation to implement, is practically abandoned nowadays and has been replaced by systems using liquid lubricants called "sizing".
Concernant les fils de chaîne, si certains peuvent être utilisés sans traitement particulier, notamment lorsqu'ils ont reçu une torsion suffisante ou un traitement spécifique, tel qu'un traitement d'entrelaçage dans le cas de fils à filaments continus, il est bien connu que pour résister aux contraintes dues aux frottements lors de l'opération de tissage, qu'après ourdissage, la nappe de fils doit recevoir un traitement d'encollage réalisé simultanément sur l'ensemble des fils de chaîne par passage à l'intérieur d'un bain de composition approprié permettant d'une part, d'agglomérer les brins élémentaires des filés, sans cependant nuire à leur élasticité de façon à avoir une bonne résistance aux frottements et aux variations de tension imposés sur le métier à tisser, et d'autre part, qui permet de lubrifier correctement les fils pour améliorer leurs caractéristiques de glissement lors de la phase de tissage.
Une telle opération d'encollage est délicate à réaliser, complique le cycle de fabrication et implique donc deux phases successives d'enroulement de la nappe de fils de chaîne, l'une lors de l'ourdissage proprement dit, la seconde qui consiste à dérouler la nappe préalablement ourdie lors de l'opération d'encollage pour la renvider, après encollage, sur l'ensouple destinée à être montée sur le métier à tisser.Regarding warp yarns, if some can be used without particular treatment, in particular when they have received sufficient twist or a specific treatment, such as an interlacing treatment in the case of yarns with continuous filaments, it is well known that to resist the stresses due to friction during the weaving operation, that after warping, the ply of threads must receive a sizing treatment carried out simultaneously on all of the warp threads by passing inside a bath of suitable composition making it possible, on the one hand, to agglomerate the elementary strands of the yarns, without however harming their elasticity so as to have good resistance to friction and to the variations in tension imposed on the loom, and on the other hand, which allows the threads to be properly lubricated to improve their sliding characteristics during the weaving phase. Such a gluing operation is delicate to carry out, complicates the manufacturing cycle and therefore involves two successive phases of winding the web of warp yarns, one during the actual warping, the second which consists of unwinding the tablecloth previously warped during the sizing operation to return it, after sizing, on the beam intended to be mounted on the loom.
Pour surmonter ces inconvénients, il a été proposé, depuis des décennies, ainsi que cela ressort des brevets français 687 510, 394 862, et éventuellement du brevet suisse 107 592, de réaliser l'encollage directement sur la machine à tisser.To overcome these drawbacks, it has been proposed for decades, as is apparent from French patents 687,510, 394,862, and possibly Swiss patent 107,592, to make the sizing directly on the weaving machine.
Ces solutions proposées antérieurement sont cependant difficiles à mettre en œuvre efficacement compte tenu du fait que l'opération d'encollage se réalise dans un espace réduit et que l'on arrive pas vraiment à imprégner une chaîne dans la masse en la faisant passer simplement sur un rouleau ou dans un bac de liquide.These solutions proposed previously are however difficult to implement effectively taking into account that the sizing operation is carried out in a reduced space and that it is not really possible to impregnate a chain in the mass by simply passing it over a roller or in a liquid container.
Or on a trouvé, et c'est ce qui fait l'objet de la présente invention, un procédé de tissage perfectionné qui permet de réaliser des articles dont la chaîne est constituée notamment de filés de fibres, et pour lesquels le tissage est réalisé directement à partir d'une ensouple d'ourdissage sans avoir à réaliser une opération d'encollage préalable.Now we have found, and this is what is the subject of the present invention, an improved weaving process which makes it possible to produce articles the warp of which consists in particular of fiber yarns, and for which the weaving is carried out directly from a warping beam without having to perform a prior gluing operation.
D'une manière générale, le procédé conforme à l'invention consiste :In general, the process according to the invention consists:
- à réaliser une chaîne ourdie comportant le nombre total de fils correspondant à l'article à réaliser, et ce directement sur une ensouple adaptable sur le métier à tisser ;- to make a warped warp comprising the total number of threads corresponding to the article to be produced, and this directly on a beam adaptable on the loom;
- puis, à partir d'une telle ensouple, à former de manière conventionnelle un tissu par :- then, from such a beam, to form a fabric in a conventional manner by:
. déroulement de la nappe de fils de chaîne,. unwinding of the warp ply,
. passage de ladite nappe sur des rouleaux de détour l'amenant dans le plan horizontal de tissage, . formation de la foule par tous moyens appropriés, lisses notamment, . insertion de la trame et battage au moyen du peigne contre la façure du tissu,. passage of said ply on detour rollers bringing it into the horizontal weaving plane,. crowd formation by all appropriate means, particularly smooth,. insertion of the weft and threshing by means of the comb against the fabric facade,
. renvidage de l'étoffe formée.
Le procédé selon l'invention se caractérise en ce que on réalise une opération d'encollage de la chaîne immédiatement après l'appel de la nappe de fils de chaîne à partir de l'ensouple de stockage, et avant passage autour du rouleau de détour l'amenant dans le plan horizontal, ladite opération d'ensimage ou d'encollage étant réalisée en séparant les fils de chaîne en deux nappes élémentaires, chaque nappe étant traitée indépendamment l'une de l'autre et recevant un liquide d'ensimage, d'encirage ou d'encollage par léchage par passage sur un rouleau immergé partiellement dans un bain de liquide. Après dépôt du liquide, la nappe de fils de chaîne est soumise à un traitement de séchage réalisé immédiatement en aval de la zone d'imprégnation, et avant que les fils de chaîne arrivent au niveau du rouleau de détour du métier à tisser formant l'entrée du plan de tissage proprement dit.. rewinding of the fabric formed. The method according to the invention is characterized in that a chain gluing operation is carried out immediately after the ply of warp threads has been called up from the storage beam, and before passing around the detour roller bringing it into the horizontal plane, said sizing or sizing operation being carried out by separating the warp threads into two elementary layers, each layer being treated independently of one another and receiving a sizing liquid, gluing or gluing by licking by passing over a roller partially submerged in a liquid bath. After the liquid has been deposited, the warp ply is subjected to a drying treatment carried out immediately downstream of the impregnation zone, and before the warp yarns reach the level of the detour roller of the weaving loom forming the entrance to the weaving plan itself.
De préférence, conformément à l'invention, les deux nappes élémentaires sont obtenues en sélectionnant un fil sur deux de l'ensemble des fils de chaîne destinés à constituer le tissu.Preferably, in accordance with the invention, the two elementary plies are obtained by selecting one thread out of two from the set of warp threads intended to constitute the fabric.
La mise en œuvre du procédé conforme à l'invention est obtenue par une simple adaptation d'un métier à tisser conventionnel en adaptant à l'entrée dudit métier un module amovible comportant l'ensemble des moyens permettant de réaliser le traitement conforme à l'invention.The implementation of the process according to the invention is obtained by a simple adaptation of a conventional weaving loom by adapting to the entry of said loom a removable module comprising all the means making it possible to carry out the treatment in accordance with invention.
Pour réaliser la séparation de la nappe de fils de chaîne en deux nappes élémentaires, ladite nappe comporte à chacune de ses extrémités une "enverjure" permettant d'obtenir sans aucune adaptation particulière la séparation de l'ensemble des fils de chaîne en deux nappes élémentaires au niveau de la zone de traitement.In order to separate the chain son ply into two elementary plies, said ply comprises at each of its ends a "spine" making it possible to obtain, without any particular adaptation, the separation of all the warp son into two elementary plies in the treatment area.
En conséquence, compte tenu du fait que pendant l'opération d'imprégnation, le nombre de fils de chaîne se trouve divisé par deux par rapport au nombre total nécessaire pour réaliser le tissu et que les deux nappes sont traitées séparément, les fils sont imprégnés de manière beaucoup plus régulière. La réunion des deux nappes élémentaires est ensuite réalisée avant l'entrée dans la machine à tisser.
L'invention et les avantages qu'elle apporte sera cependant mieux comprise grâce à l'exemple de réalisation qui suit, donné à titre indicatif mais non limitatif, et qui est illustré par les schémas annexés dans lesquels :Consequently, taking into account that during the impregnation operation, the number of warp threads is divided by two compared to the total number necessary to make the fabric and that the two plies are treated separately, the threads are impregnated much more regularly. The two elementary layers are then brought together before entering the weaving machine. The invention and the advantages which it brings will however be better understood thanks to the embodiment which follows, given by way of indication but not limitation, and which is illustrated by the appended diagrams in which:
. la figure 1 est une vue schématique, de côté, montrant l'alimentation en chaîne d'un métier à tisser adapté pour mettre en œuvre le procédé conforme à l'invention ;. Figure 1 is a schematic side view showing the chain feed of a weaving loom adapted to implement the method according to the invention;
• la figure 2 est une vue de détail montrant la manière dont est réalisée la séparation de la nappe de chaîne en deux nappes élémentaires ;• Figure 2 is a detail view showing the manner in which the separation of the chain ply into two elementary plies is carried out;
• la figure 3 illustre de manière schématique comment est réalisée l'imprégnation des nappes élémentaires de fils de chaîne par contact sur un rouleau lécheur.• Figure 3 illustrates schematically how the impregnation of the elementary plies of warp yarns is carried out by contact on a wetting roller.
Pour réaliser le tissu, de manière conventionnelle, on réalise une chaîne ourdie comportant le nombre total de fils (1) correspondant à l'article à réaliser, et ce directement sur une ensouple, désignée par la référence générale (2), montée sur le métier à tisser.To make the fabric, in a conventional manner, a warped chain is produced comprising the total number of threads (1) corresponding to the article to be produced, and this directly on a beam, designated by the general reference (2), mounted on the loom.
En se reportant à la figure 1 annexée, le procédé conforme à l'invention est mis en œuvre sur un métier à tisser conventionnel adapté pour sa mise en œuvre.Referring to Figure 1 attached, the method according to the invention is implemented on a conventional weaving loom suitable for its implementation.
Pour la réalisation du tissu, à partir de l'ensouple (2), on procède de manière conventionnelle par :For the production of the fabric, starting from beam (2), the procedure is conventional:
. déroulement de la nappe de fils de chaîne (1),. unwinding of the warp ply (1),
• passage autour d'un rouleau de détour (3) amenant la nappe de chaîne (1) dans le plan horizontal de tissage.• passage around a detour roller (3) bringing the warp ply (1) in the horizontal weaving plane.
De manière connue, et cela n'est pas représenté à la figure 1 , les fils de chaîne maintenus à plat sont donc amenés aux moyens permettant la formation de la foule, moyens constitués par des lisses comportant des œillets pour le guidage du fil de chaîne. La foule étant formée, le fil de trame est introduit et l'on procède ensuite au battage au moyen d'un peigne contre la façure du tissu produit, tissu qui après passage autour d'un rouleau de détour de sortie, est renvidé sous la forme d'un rouleau.
Conformément à l'invention, immédiatement après l'appel de la nappe de fils (1) à partir de leur ensouple de stockage, et avant passage autour du rouleau de détour (3), la nappe de fils de chaîne (1) est divisée en deux nappes élémentaires (l a, lb). Ces deux nappes élémentaires (la, lb) passent sur deux ensembles de traitement similaires, permettant de déposer autour de chaque fil de chaîne une composition d'ensimage, encirage, voire encollage, permettant d'agglomérer les brins élémentaires en les lubrifiant.In a known manner, and this is not shown in FIG. 1, the warp threads kept flat are therefore brought to the means allowing the formation of the crowd, means constituted by heddles comprising eyelets for guiding the warp thread . The shed being formed, the weft thread is introduced and then threshing is carried out by means of a comb against the face of the fabric produced, fabric which after passing around an exit detour roll, is returned under the shape of a roll. According to the invention, immediately after calling up the ply of threads (1) from their storage beam, and before passing around the detour roller (3), the ply of warp threads (1) is divided in two elementary layers (la, lb). These two elementary layers (la, lb) pass over two similar treatment assemblies, making it possible to deposit around each warp yarn a composition for sizing, drawing, or even sizing, making it possible to agglomerate the elementary strands by lubricating them.
De manière simple, ainsi que cela ressort de la figure 2, la division de la nappe de fils de chaîne (1) en deux nappes élémentaires (la, lb) est réalisée en prévoyant à chaque extrémité de la chaîne ourdie des enverjures (3a, 3b ; 4a, 4b) permettant aussi d'obtenir directement sur le métier deux nappes élémentaires comportant le même nombre de fils.In a simple manner, as can be seen from FIG. 2, the division of the ply of warp threads (1) into two elementary plies (la, lb) is carried out by providing at each end of the warped chain spines (3a, 3b; 4a, 4b) also making it possible to obtain directly on the loom two elementary plies comprising the same number of wires.
Pour réaliser l'opération d'ensimage ou d'encollage, de préférence on utilise deux ensembles similaires montés en aval du rouleau de détour (5) prévu immédiatement à la sortie de l'ensouple (2).To carry out the sizing or sizing operation, preferably two similar assemblies are used mounted downstream of the detour roller (5) provided immediately at the exit of the beam (2).
Chacun de ces ensembles, désignés par les mêmes références, comporte, montés sur un bâti, ledit rouleau de détour (5) et deux systèmes d'imprégnation désignés par la référence générale (6).Each of these assemblies, designated by the same references, comprises, mounted on a frame, said detour roller (5) and two impregnation systems designated by the general reference (6).
Chaque système d'imprégnation comporte un bac contenant le liquide (ensimage ou encollage), liquide qui est déposé sur les fils par contact tangentiel contre des rouleaux immergés (7).Each impregnation system comprises a tank containing the liquid (sizing or sizing), liquid which is deposited on the wires by tangential contact against immersed rollers (7).
Un moyen additionnel peut être utilisé pour assurer le séchage de la nappe après imprégnation.An additional means can be used to ensure the drying of the sheet after impregnation.
Un tel séchage peut par exemple être réalisé simplement à l'air libre, un rouleau réglable additionnel étant prévu entre l'ensemble de dépose du produit d'encollage et le rouleau de détour (3). Lorsque les fils des deux nappes élémentaires (la, lb) sont secs,
ils sont rassemblés sous la forme d'une nappe unique (1) qui est amenée au niveau de la zone de tissage proprement dite.Such drying can for example be carried out simply in the open air, an additional adjustable roller being provided between the assembly for depositing the sizing product and the detour roller (3). When the threads of the two elementary layers (la, lb) are dry, they are brought together in the form of a single sheet (1) which is brought to the level of the weaving area proper.
Ainsi que cela ressort de la figure 3, l'un des principaux avantages que présente le procédé conforme à l'invention, est de permettre de diviser par deux les fils lors de la phase d'imprégnation, ce qui permet d'obtenir une meilleure répartition du liquide d'encollage.As shown in Figure 3, one of the main advantages of the process according to the invention, is to allow to halve the son during the impregnation phase, which allows to obtain a better distribution of the sizing liquid.
Bien entendu, l'invention n'est pas limitée à l'exemple de réalisation donné précédemment, mais elle en couvre toutes les variantes réalisées dans le même esprit.
Of course, the invention is not limited to the embodiment given above, but it covers all the variants produced in the same spirit.
