Description

La présente invention a trait à un dispositif perfectionné permettant de réaliser des lisières sur les bords latéraux de tissus obtenus sur des métiers à tisser du type "sans navette", dans lesquels la trame insérée est coupée sur au moins l'un des côtés du tissu après son insertion dans la foule.The present invention relates to an improved device for making selvedges on the lateral edges of fabrics obtained on weaving looms of the "shuttleless" type, in which the inserted weft is cut on at least one of the sides of the fabric. after being inserted into the crowd.

La solution la plus répandue à ce jour pour réaliser des lisières sur les tissus obtenus sur les métiers à tisser sans navette, consiste à faire travailler un certain nombre de fils situés à proximité des bords du tissu selon une armure pas de gaze, permettant ainsi d'emprisonner les extrémités du fil de trame de chaque côté. Pour assurer un renforcement au niveau de la lisière lors du tissage, il a été proposé de faire travailler au moins une paire de fils additionnels selon une armure toile à côté des fils travaillant en armure gaze, cette portion en armure toile étant découpée après réalisation du tissu.The most widespread solution to date for making selvedges on the fabrics obtained on the weaving looms without shuttle, consists in making work a certain number of threads located near the edges of the fabric according to a weave not gauze, thus allowing d '' trap the ends of the weft thread on each side. To ensure reinforcement at the edge during weaving, it has been proposed to make work at least one pair of additional threads in a web weave next to the threads working in gauze weave, this portion in web weave being cut after completion of the tissue.

Pour mémoire, par armure tissée "pas de gaze", on entend la technique qui, par rapport à un tissu chaîne et trame conventionnel, consiste non seulement à déplacer les fils de chaine par rapport aux fils de trame pour réaliser leur liaison, mais également à déplacer les fils de chaine les uns par rapport aux autres latéralement, deux par deux, de telle sorte que l'un des fils dits "fil de tour" passe alternativement de part et d'autre de l'autre fil dit "fil fixe", la trame étant emprisonnée et se trouvant bloquée entre ces deux fils qui ne peuvent donc pas glisser par rapport à cette dernière.As a reminder, by woven weave "no gauze" is meant the technique which, compared to a conventional warp and weft fabric, consists not only of moving the warp threads relative to the weft threads to make their connection, but also to move the warp threads relative to each other laterally, two by two, so that one of the so-called "lathe thread" passes alternately on either side of the other so-called "fixed thread"", the frame being trapped and being blocked between these two wires which cannot therefore slide with respect to the latter.

Une telle technique de tissage de type "gaze" est connue depuis fort longtemps et consiste essentiellement à adapter les métiers à tisser pour que les fils de chaine puissent non seulement recevoir des mouvements verticaux pour former la foule, mais également des mouvements transversaux pour les lier entre eux deux à deux.Such a weaving technique of the "gauze" type has been known for a very long time and essentially consists in adapting the weaving looms so that the warp threads can not only receive vertical movements to form the crowd, but also transverse movements to bind them. between them two by two.

Pour réaliser le déplacement latéral des fils de chaine deux à deux, on utilise des lisses spéciales dites "lisses gaze", constituées d'au moins deux lisses de levée associées à une culotte guidée par ces lisses et qui est entraînée à tour de rôle par l'une d'elles.To carry out the lateral displacement of the warp threads two by two, special healds known as "gauze healds" are used, consisting of at least two lifting healds associated with pants guided by these healds and which is in turn driven by one of them.

De tels dispositifs sont bien connus des techniciens et ressortent notamment du FR-A-2 273 893 et EP-A-344 536, ce dernier document décrivant plus spécifiquement l'application de cette technique pas de gaze pour la réalisation des lisières de tissu.Such devices are well known to technicians and emerge in particular from FR-A-2 273 893 and EP-A-344 536, the latter document more specifically describing the application of this no gauze technique for the production of selvedges of fabric.

Si pour les métiers à tisser conçus pour produire en permanence des mêmes articles, la formation de lisières à pas de gaze selon cette technologie ne pose pas de problème, en revanche, en ce qui concerne les machines polyvalentes, il est souhaitable que les dispositifs permettant de réaliser lesdites lisières soient indépendants du cadre de la machine.If for weaving looms designed to permanently produce the same articles, the formation of selvedges with no gauze using this technology does not pose a problem, on the other hand, as regards multipurpose machines, it is desirable that the devices allowing to make said selvedges are independent of the frame of the machine.

Pour ce faire, on utilise actuellement des systèmes à came réglable angulairement associés à une liaision mécanique avec le dispositif permettant de réaliser les lisières et autorisant des réglages en fonction du type d'articles tissés. Une telle manière de procéder ressort notamment du FR-A-2 655 359.To do this, angularly adjustable cam systems are currently used, associated with a mechanical connection with the device making it possible to make the selvedges and allowing adjustments as a function of the type of woven articles. Such a procedure is apparent in particular from FR-A-2 655 359.

De tels ensembles de réalisation de lisières indépendants des moyens permettant de réaliser le fond du tissu, présentent l'avantage d'avoir une foule minimum pour le fond, de pouvoir décaler le croisement des fils de lisière par rapport au fond ainsi que de décaler le croisement des fils de lisière entre la droite et la gauche de la machine. Ainsi, il est possible par exemple, pour un moment de croisure du fond réglable autour d'un angle machine de 305 à 345°, d'avoir une lisière droite réglable autour d'un angle machine moyen de 305° et une lisière gauche autour d'un angle machine moyen de 325°.Such sets for making selvedges independent of the means making it possible to produce the bottom of the fabric, have the advantage of having a minimum crowd for the bottom, of being able to offset the crossing of the selvedge threads relative to the bottom as well as of shifting the crossover of selvedge wires between the right and left of the machine. Thus, it is possible for example, for a bottom crossover moment adjustable around a machine angle of 305 to 345 °, to have a right selvedge adjustable around an average machine angle of 305 ° and a left selvedge around with an average machine angle of 325 °.

Les problèmes que posent les solutions techniques proposées à ce jour dans lesquelles on réalise la commande des organes permettant la formation de lisières au moyen de cames, ont cependant comme inconvénient de ne pas pouvoir permettre de modifier facilement sur un métier la largeur du tissu produit, ainsi que de ne pas pouvoir réaliser plusieurs laizes côte à côte sur un même métier. Par ailleurs, cette commande par cames ne permet pas de pouvoir piloter les réglages de la machine à partir d'un microprocesseur ni d'envisager de reproduire automatiquement et directement de tels réglages d'une machine à l'autre.The problems posed by the technical solutions proposed to date in which control of the members allowing the formation of selvedges by means of cams is carried out, however have the drawback of not being able to allow the width of the fabric produced to be easily modified on a loom. as well as not being able to make several widths side by side on the same loom. Furthermore, this cam control does not make it possible to be able to control the machine settings from a microprocessor or to envisage automatically and directly reproducing such settings from one machine to another.

Or on a trouvé, et c'est ce qui fait l'objet de la présente invention, une solution simple qui permet de résoudre l'ensemble de ces problèmes.However, we have found, and this is what is the subject of the present invention, a simple solution which makes it possible to solve all of these problems.

D'une manière générale, l'invention concerne un dispositif perfectionné permettant la réalisation d'une fausse lisière à pas de gaze sur chaque côté d'un tissu produit sur une machine à tisser sans navette, dispositif du type selon lequel au moins deux fils latéraux travaillent selon une armure à pas de gaze obtenue par l'intermédiaire de deux lisses de levée entraînant une culotte permettant de réaliser le déplacement latéral d'un fil de chaine par rapport à l'autre, ledit ensemble étant commandé indépendamment des moyens permettant d'assurer le déplacement des fils de chaine pour réaliser le fond du tissu et il se caractérise en ce que chaque ensemble de formation des lisières disposées de part et d'autre du tissu comporte au moins deux lisses à mailles culotte permettant la réalisation de l'armure gaze, lesdites lisses étant montées en parallèle entre deux supports animés d'un mouvement alternatif de monte et baisse obtenus par l'intermédiaire d'un moteur.In general, the invention relates to an improved device allowing the production of a false selvedge with no gauze on each side of a fabric produced on a weaving machine without shuttle, device of the type according to which at least two threads lateral work in a weave with a gauze pitch obtained by means of two lifting beams driving a panty making it possible to carry out the lateral displacement of one warp thread relative to the other, said assembly being controlled independently of the means allowing '' ensure displacement of the warp threads to make the bottom of the fabric and it is characterized in that each set for forming the selvedges disposed on either side of the fabric comprises at least two smooth mesh breeches enabling the gauze weave to be produced, said stringers being mounted in parallel between two supports animated by an alternating up and down movement obtained by means of a motor.

Si un tel dispositif permettant de réaliser une fausse lisière pas de gaze peut être disposé de chaque côté du métier permettant ainsi de réaliser sur ce dernier une seule largeur de tissu, il peut également être envisagé de disposer de tels dispositifs en position intermédiaire sur la largeur du métier, permettant d'obtenir ainsi deux lés de tissu par simple découpe entre les zones travaillant en armure gaze dans la zone centrale.If such a device making it possible to produce a false selvedge, no gauze can be placed on each side of the loom, thus making it possible to produce a single width of fabric on the latter, it can also be envisaged to have such devices in an intermediate position across the width. of the trade, thus making it possible to obtain two strips of fabric by simple cutting between the zones working in gauze weave in the central zone.

Par ailleurs, selon une forme de réalisation, l'ensemble de formation de chaque lisière sur les bords latéraux du métier comporte avantageusement deux paires de lisses permettant la réalisation d'une armure gaze et, à côté de ces dernières, montées sur les mêmes supports, plusieurs paires de lisses permettant la formation d'une armure toile. Cette zone en armure toile est en général éliminée par découpe et mise aux déchets avant le renvidage du tissu pour ne laisser subsister sur les côtés de ce dernier que la lisière pas de gaze.Furthermore, according to one embodiment, the formation assembly of each selvedge on the lateral edges of the loom advantageously comprises two pairs of healds allowing the production of a gauze weave and, next to these latter, mounted on the same supports , several pairs of heddles allowing the formation of a canvas weave. This area in canvas weave is generally eliminated by cutting and putting in waste before the rewinding of the fabric so as to leave on the sides of the latter only the selvedge, no gauze.

Les déplacements alternatifs de monte et baisse des lisses seront transmis par tous moyens appropriés ; selon une forme de réalisation, les supports de lisses sont portés par les deux brins d'une courroie sans fin déplacée d'une valeur prédéterminée alternativement dans deux directions opposées par l'intermédiaire d'un moteur électrique de type pas à pas.The alternative movements of raising and lowering of the beams will be transmitted by all appropriate means; according to one embodiment, the heald supports are carried by the two strands of an endless belt displaced by a predetermined value alternately in two opposite directions by means of an electric motor of the stepping type.

Grâce à une telle conception de commande, il est possible de régler aisément l'angle où se croisent les fils indépendamment pour chaque lisière, ce réglage étant programmé en fonction de l'article au moyen d'un microprocesseur au même titre que les autres réglages textiles pour un type d'article.Thanks to such a control design, it is possible to easily adjust the angle where the wires cross independently for each selvedge, this adjustment being programmed according to the article by means of a microprocessor in the same way as the other adjustments. textiles for an article type.

Par ailleurs, un tel ensemble à commande individuelle élimine les problèmes de transmission mécanique, d'usure et d'entretien que présentent les systèmes de commande par came.Furthermore, such an individually controlled assembly eliminates the problems of mechanical transmission, wear and maintenance presented by cam control systems.

Enfin, un tel ensemble peut être facilement adapté en fonction de la largeur de l'article produit.Finally, such an assembly can be easily adapted according to the width of the article produced.

L'invention et les avantages qu'elle apporte seront cependant mieux compris grâce à 1' exemple de réalisation concret décrit ci-après à titre indicatif mais non limitatif, et qui est illustré par les deux schémas annexés dans lesquels :

  • la figure 1 illustre schématiquement la structure d'une lisière réalisée grâce au dispositif conforme à l'invention ;
  • la figure 2 est une vue en perspective d'un dispositif de formation de lisières conformément à l'invention.
The invention and the advantages which it provides will however be better understood thanks to the concrete example of embodiment described below by way of indication but not limitation, and which is illustrated by the two appended diagrams in which:
  • Figure 1 schematically illustrates the structure of an edge made with the device according to the invention;
  • Figure 2 is a perspective view of a selvedge forming device according to the invention.

En se reportant aux schémas annexés, l'invention concerne donc un dispositif permettant de réaliser sur les bords d'un tissu obtenu sur un métier sans navette, des lisières (L) du type illustré à la figure 1 annexée, disposées de chaque côté du fond (F) du tissu (non représenté sur cette figure 1), et qui comportent chacune au moins une paire de fils de chaine (1,2) travaillant selon une armure gaze, et à côté desquels est disposée de préférence au moins une paire de fils (3,4) travaillant selon une armure unie par rapport aux fils de trame (5a,5b,..) qui sont coupés après insertion dans la foule.Referring to the appended diagrams, the invention therefore relates to a device making it possible to produce, on the edges of a fabric obtained on a loom without shuttle, selvedges (L) of the type illustrated in attached FIG. 1, arranged on each side of the bottom (F) of the fabric (not shown in this figure 1), and which each comprise at least one pair of warp threads (1,2) working in a gauze weave, and next to which is preferably arranged at least one pair son (3,4) working in a plain weave relative to the weft son (5a, 5b, ..) which are cut after insertion into the crowd.

En pratique, très souvent, les lisières sont réalisées de manière à comporter deux paires de fils de chaine travaillant en armure gaze et deux paires (ou plus) de fils de chaine travaillant en armure toile, ces zones latérales en armure toile étant ensuite découpées et mises aux déchets avant renvidage du tissu réalisé.In practice, very often, the selvedges are made so as to comprise two pairs of warp threads working in gauze weave and two (or more) pairs of warp threads working in canvas weave, these lateral zones in canvas weave being then cut out and put in the waste before rewinding the fabric produced.

Les déplacements des fils (1,2,3,4) pour la réalisation de la lisière, sont obtenus d'une part par l'intermédiaire d'une paire de lisses type gaze, réalisées conformément aux enseignements de l'EP 344 536, comprenant deux lisses de levée (5a,5b) associées à une maille culotte (10) à l'intérieur de laquelle passe le fil fixe (2), l'ensemble permettant donc non seulement de réaliser la foule entre le fil fixe (2) et le fil de tour (1), mais également le déplacement latéral dudit fil de tour (1), et d'autre part, par des lisses conventionnelles (6a,6b) assurant et commandant des déplacements relatifs des fils de chaine (3) et (4) formant armure toile à côté de la lisière gaze, centre que l'on découpe avant renvidage du tissu.The displacements of the wires (1,2,3,4) for the production of the selvedge are obtained on the one hand by means of a pair of gauze type healds, produced in accordance with the teachings of EP 344 536, comprising two lifting beams (5a, 5b) associated with a panty mesh (10) inside which the fixed wire (2) passes, the assembly therefore making it possible not only to create the crowd between the fixed wire (2) and the lathe wire (1), but also the lateral displacement of said lathe wire (1), and on the other hand, by conventional heddles (6a, 6b) ensuring and controlling relative displacements of the warp wires (3) and (4) forming canvas weave next to the gauze selvedge, center which is cut before the fabric is wound up.

Conformément à l'invention, les lisses (5a,6a) et (5b,6b) sont montées en parallèle entre des supports communs (7a,8a,7b,8b) pouvant recevoir un mouvement alternatif de monte et baisse.According to the invention, the heddles (5a, 6a) and (5b, 6b) are mounted in parallel between common supports (7a, 8a, 7b, 8b) capable of receiving an alternating up and down movement.

Pour ce faire, les supports (7a,8a) et (7b,8b) sont montés en opposition sur les deux brins (9a,9b) d'une courroie sans fin (9) dont le déplacement alternatif est obtenu par l'intermédiaire d'un moteur pas à pas (11) commandant un pignon (12) autour duquel passe la courroie (9).To do this, the supports (7a, 8a) and (7b, 8b) are mounted in opposition on the two strands (9a, 9b) of an endless belt (9) whose alternative movement is obtained by means of d 'a stepping motor (11) controlling a pinion (12) around which the belt (9) passes.

Grâce à un tel ensemble, chaque lisière est donc réalisée indépendamment des moyens de commande généraux permettant la formation du fond du tissu.Thanks to such an assembly, each selvedge is therefore produced independently of the general control means allowing the bottom of the fabric to be formed.

Il est donc possible de pouvoir décaler le croisement des fils de lisière par rapport à celui des fils du fond, et également de pouvoir décaler le croisement des fils de lisière entre la droite et la gauche de la machine en assurant la commande du moteur (11) au moyen d'informations fournies par un microprocesseur comportant l'ensemble des réglages textiles de l'article à réaliser.It is therefore possible to be able to offset the crossing of the selvedge wires with respect to that of the bottom wires, and also to be able to offset the crossing of the selvedge wires between the right and the left of the machine by controlling the motor (11 ) by means of information supplied by a microprocessor comprising all the textile adjustments of the article to be produced.

Un tel ensemble de conception particulièrement simple peut être adapté sur n'importe quel type de métier sans navette, et ce quelle que soit la largeur de l'article à réaliser.Such a particularly simple design assembly can be adapted to any type of loom without shuttle, regardless of the width of the article to be produced.
