Description

IntroductionIntroduction

La présente invention concerne un procédé de fabrication de produits textiles touffetés tels que par exemple des dalles textiles touffetées.The present invention relates to a method for manufacturing textile products tufted such as for example tufted textile tiles.

Etat de la techniqueState of the art

Le touffetage est aujourd'hui la technique la plus courante pour la production de moquettes. Les moquettes touffetées sont fabriquées en piquant une multiplicité de fils à travers une couche de fond pour former des boucles, laissées intactes ou coupées, qui constituent alors le velours de la moquette.Tufting is the most common technique for production today carpets. Tufted carpets are made by stitching a multiplicity of threads through a base layer to form loops, left intact or cut, which then constitutes the velvet of the carpet.

La technique de touffetage permet de réaliser des motifs colorés en agissant sur l'implantation des fils par les barres à aiguilles de la machine à touffeter, qui s'étendent sur toute la largeur de la couche de base. Les motifs réalisables avec les machines classiques sont toutefois extrêmement répétitifs et très limités.The tufting technique makes it possible to produce colored patterns by acting on the implantation of the threads by the needle bars of the tufting machine, which extend over the entire width of the base layer. The achievable patterns with conventional machines are however extremely repetitive and very limits.

Dans les machines à touffeter plus évoluées, chaque fil est muni d'un contrôle d'alimentation, ce qui permet de créer des hauteurs de boucle différentes. Les fils utilisés sont de coloris différents et leur implantation sur la barre à aiguilles, combinée à la différence de hauteur des boucles, permet de créer des dessins.In more advanced tufting machines, each thread has a feed control, allowing you to create different loop heights. The wires used are of different colors and their location on the bar needles, combined with the difference in height of the loops, creates drawings.

Ces dessins sont moins systématiquement répétitifs du fait que certaines boucles, présentant une coloration différente de leurs voisines, peuvent quelquefois apparaítre dans un dessin si elles ont la même hauteur que leurs voisines, ou disparaítre si elles ont une hauteur de boucle inférieure, en étant recouverte dans ce cas par leurs voisines.These drawings are less systematically repetitive because some curls, presenting a different coloring from their neighbors, can sometimes appear in a drawing if they have the same height as their neighbors, or disappear if they have a lower loop height, being covered in this case by their neighbors.

Un désavantage de la technique de touffetage est l'instabilité dimensionnelle de la couche de base, qui est particulièrement problématique dans la fabrication de dalles textiles touffetées. Les dalles sont généralement fabriquées en réalisant une nappe touffetée de grande dimension, qui est ensuite découpée au format des dalles. Comme la couche de base n'est pas stable au niveau dimensionnel, la nappe touffetée a tendance à s'étirer, notamment dans le sens longitudinal (sens de fabrication). Cela est problématique pour la production de dalles car il est alors difficile de garantir qu'après découpe, les dalles pourront être proprement raccordées entre elles. C'est pourquoi la plupart des dalles de moquette touffetées sont à motifs dits "all-over" pour pose dans le "même sens" ou bien à motifs comprenant des dessins géométriques avec pose obligatoire en damier, ce qui limite les possibilités décoratives.A disadvantage of the tufting technique is dimensional instability of the base layer, which is particularly problematic in the manufacture of tufted textile tiles. The tiles are generally made by making a large tufted tablecloth, which is then cut to the format of the tiles. As the base layer is not stable at dimensional level, the tufted sheet tends to stretch, especially in the longitudinal direction (manufacturing direction). This is problematic for the production of slabs because it is then difficult to guarantee that after cutting, the slabs can be properly connected together. This is why the most tufted carpet tiles have so-called "all-over" patterns for laying in the "same direction" or with patterns including geometric designs with mandatory checkerboard installation, which limits the decorative possibilities.

Le document EP 1 148 171 A1 décrit un procédé de fabrication de produits textiles touffetés pourvus de décorations sous forme de dessins géométriques ou non, dans lequel on produit au départ d'au moins deux fils des structures uniformes et régulières et on dépose ensuite, selon un motif préétabli, différentes pâtes de colorations différentes et d'affinité spécifique pour chaque type de fil. Pour la fabrication de dalles, la nappe touffetée est d'abord découpée au format des dalles, puis les pâtes de coloration sont appliquées sur les dalles. Ce procédé permet donc de fabriquer des dalles raccordables à dessins géométriques, puisque l'opération de coloration se fait directement sur la dalle après découpage. Toutefois, un tel procédé est relativement complexe, puisqu'il implique de traiter individuellement chaque dalle, et fait intervenir une étape supplémentaire de coloration.Document EP 1 148 171 A1 describes a process for manufacturing products tufted textiles with decorations in the form of geometric designs or not, in which at least two wires are produced from structures uniform and regular and then deposit, according to a pre-established pattern, different pastes of different colors and specific affinity for each wire type. For the production of tiles, the tufted sheet is first cut in the format of the tiles, then the coloring pastes are applied to the slabs. This process therefore makes it possible to manufacture slabs which can be connected to drawings. geometric, since the coloring operation is done directly on the slab after cutting. However, such a process is relatively complex, since it involves treating each slab individually, and involves a step additional coloring.

Objet de l'inventionSubject of the invention

L'objet de la présente invention est de proposer un procédé amélioré de fabrication de produits textiles touffetés, qui permet notamment la fabrication de dalles textiles touffetées à dessins géométriques pouvant être raccordées. Cet objectif est atteint par un procédé selon la revendication 1.The object of the present invention is to provide an improved method of manufacture of tufted textile products, which allows in particular the manufacture of Tufted textile tiles with geometric designs that can be connected. This objective is achieved by a method according to claim 1.

Exposé de l'inventionStatement of the invention

Conformément à l'invention, on propose un procédé de fabrication de produits textiles touffetés, dans lequel on implante une multiplicité de fils dans une couche de base par une technique de touffetage. L'implantation des fils est réalisée de sorte à former une nappe touffetée comprenant au moins un motif décoratif, une ligne de guidage parallèle à la direction de fabrication de la nappe touffetée, ainsi que des repères de coupe placés à des positions prédéterminées de la nappe touffetée. On découpe ensuite la nappe touffetée sur base de la position de la ligne de guidage et des repères de coupe pour former des produits textiles touffetés, tels que par exemple des dalles textiles touffetées.In accordance with the invention, a method of manufacturing products is proposed. tufted textiles, in which a multiplicity of threads are implanted in a base layer by a tufting technique. The implantation of the wires is produced so as to form a tufted sheet comprising at least one pattern decorative, a guide line parallel to the manufacturing direction of the tufted tablecloth, as well as cutting marks placed at predetermined positions of the tufted tablecloth. Then cut the tufted tablecloth on base of guide line position and cut marks to form tufted textile products, such as for example tufted textile tiles.

On appréciera que, dans le présent procédé, les repères de coupe et la ligne de guidage sont implantés dans la couche de base en même temps que les motifs décoratifs. Les touffes formant la ligne de guidage, respectivement les repères de coupe, constituent donc un système d'indexation de la nappe touffetée qui fait partie intégrante du touffetage réalisé. Dans la technique de touffetage, l'implantation des fils se fait typiquement par des barres à aiguilles qui s'étendent sur toute la largeur de la couche de base. La couche de base est avancée sous les barres à aiguilles (dans le sens de fabrication) et l'implantation se fait rangée après rangée (transversalement au sens de fabrication). En implantant la ligne de guidage et les repères de coupe en même temps que le ou les motifs décoratifs, il est donc possible de les positionner avec une grande précision par rapport à ces motifs décoratifs. Ainsi, malgré les déformations que peut subir la nappe touffetée en raison du manque de stabilité dimensionnelle de la couche de base, les repères de coupe sont toujours positionnés de la même manière par rapport aux motifs décoratifs. La nappe touffetée peut alors être découpée avec une grande précision par rapport aux motifs, ce qui permet de garantir la qualité du raccord entre dalles.It will be appreciated that, in the present process, the cutting marks and the guide line are implanted in the base layer at the same time as decorative patterns. The tufts forming the guide line, respectively the cutting marks, therefore constitute a system for indexing the web tufted which is an integral part of the tufting carried out. In the technique of tufting, the implantation of the threads is typically done by needle bars which extend over the entire width of the base layer. The base layer is advanced under the needle bars (in the manufacturing direction) and installation is done row after row (transversely to the manufacturing direction). In setting out the guide line and the cutting marks at the same time as the or decorative patterns, so it is possible to position them with great precision in relation to these decorative patterns. So, despite the distortions that may undergo the tufted web due to lack of dimensional stability of the base layer, the cut marks are always positioned from the same way compared to decorative patterns. The tufted tablecloth can then be cut with great precision in relation to the patterns, which allows to guarantee the quality of the connection between slabs.

En outre, en réalisant le marquage de la nappe touffetée lors de sa fabrication conformément à l'invention, on élimine toute étape de marquage postérieure à la fabrication de la nappe touffetée, qui serait moins précise et allongerait le procédé de fabrication.In addition, by marking the tufted web during its manufacture in accordance with the invention, any subsequent marking step is eliminated to the manufacture of the tufted tablecloth, which would be less precise and would lengthen the manufacturing process.

Comme souligné par ex. dans EP 1 148 171 A1, la réalisation de dalles textiles à motifs géométriques requiert une découpe précise afin de garantir le raccord entre dalles. Dans ce procédé connu, on pallie le problème du raccord des dalles en réalisant les motifs géométriques au moyen de pâtes colorées, une fois les dalles découpées. On appréciera que le procédé selon la présente invention permet de réaliser une nappe touffetée à motifs géométriques, qui, sur base du système d'indexation formé par la ligne de guidage et les repères de coupe, peut être découpée avec précision en dalles. Le présent procédé permet donc de fabriquer des dalles textiles touffetées à motifs géométriques qui peuvent être correctement raccordées.As pointed out e.g. in EP 1 148 171 A1, the production of slabs textiles with geometric patterns requires precise cutting to guarantee connection between slabs. In this known method, the problem of the connection is overcome slabs by making the geometric patterns using colored pastes, once the tiles have been cut. It will be appreciated that the method according to the present invention makes it possible to produce a tufted tablecloth with geometric patterns, which based on the indexing system formed by the guide line and the marks cutting, can be precisely cut into slabs. The present process therefore allows the production of tufted textile tiles with geometric patterns which can be correctly connected.

On comprendra que la ligne de guidage et les repères de coupe sont de préférence placés dans des zones de la nappe touffetée qui feront partie des chutes de découpe. Dans une variante préférée, la ligne de guidage est implantée en bordure de la nappe touffetée. Les repères de coupe peuvent être disposés adjacents à la ligne de guidage, à des intervalles prédéterminés. On peut ainsi obtenir, en bordure de la nappe touffetée, une indication de l'axe longitudinal de la nappe touffetée par la ligne de guidage, ainsi qu'une indexation dans le sens transversal de la nappe touffetée par les repères de coupe. Pour un repérage plus facile, on pourra aussi prévoir une deuxième ligne de guidage sur le bord opposé de la nappe touffetée, ainsi qu'une série de repères de coupe.It will be understood that the guide line and the cutting marks are of preferably placed in areas of the tufted tablecloth that will be part of cutting scraps. In a preferred variant, the guide line is located on the edge of the tufted sheet. The cutting marks can be arranged adjacent to the guide line, at predetermined intervals. We can thus obtain, at the edge of the tufted sheet, an indication of the axis longitudinal of the sheet tufted by the guide line, as well as an indexing in the transverse direction of the sheet tufted by the cutting marks. For easier identification, we can also provide a second line of guidance on the opposite edge of the tufted web, as well as a series of marks cutting.

La découpe de la nappe touffetée se fait de préférence dans une presse à découper équipée de moyens de détection optiques pour un guidage automatisé de la nappe touffetée. A cet effet, la ligne de guidage, respectivement les repères de coupe, sont avantageusement formés par des touffes de couleurs contrastantes, ce qui facilite leur détection. On emploiera par exemple le blanc ou le jaune pour la ligne de guidage et les repères de coupe lorsque les touffes voisines sont noires, grises ou bleues.The cut of the tufted web is preferably done in a press cutting equipped with optical detection means for automated guidance of the tufted tablecloth. For this purpose, the guide line, respectively the cut marks, are advantageously formed by tufts of colors contrasting, which facilitates their detection. We will use for example white or yellow for the guide line and the cut marks when the tufts neighbors are black, gray or blue.

De préférence, on découpe d'abord la nappe touffetée en bandes transversales selon les repères de coupe; puis on découpe chaque bande transversale en produits textiles touffetés en se basant sur la ligne de guidage.Preferably, the tufted sheet is first cut into transverse strips according to the cutting marks; then we cut each cross strip in tufted textile products based on the guide line.

Afin de protéger l'envers des produits textiles touffetés, on pourra soumettre la nappe touffetée à une enduction classique à base de latex avant de la découper. On peut ainsi former une couche inférieure stabilisatrice pour une utilisation en revêtement de sol.In order to protect the back of tufted textile products, the tufted tablecloth with a conventional latex-based coating before the cut. It is thus possible to form a lower stabilizing layer for a use in flooring.

Le présent procédé est particulièrement intéressant pour la fabrication de dalles textiles touffetées, car il permet de garantir le raccordement des dalles produites. Suivant la technique de touffetage employée pour l'implantation des fils, on peut fabriquer des dalles à velours coupés ou velours bouclés unis et simples. Il est également possible de touffeter un dessin géométrique (technologies graphics ou hydrashift) ou de former un dessin par une différence de hauteur du velours (technologies scroll et cutloop).The present process is particularly interesting for the manufacture of tufted textile tiles, as it guarantees the connection of the tiles produced. According to the tufting technique used for the implantation of yarn, you can make slabs of cut pile or plain loop pile and Simple. It is also possible to tuft a geometric design (technologies graphics or hydrashift) or to form a design by a difference of velvet height (scroll and cutloop technologies).

La Fig.1 est utilisée pour décrire plus en détail, à titre d'illustration de la présente invention, le déroulement d'un procédé de fabrication de dalles textiles touffetées. On y voit schématiquement une machine à touffeter 10 alimentée par une multiplicité de fils 12. Ces fils 12 sont implantés dans une couche de base 14 au moyen d'une série d'aiguilles, placées sur une ou plusieurs barres à aiguilles (non montrées) s'étendant sur toute la largeur de la couche de base 14, pour former une nappe touffetée 16. Cette série d'aiguilles, dont chacune est préférablement alimentée par une bobine de fil séparée, pique les fils 12 à travers la couche de base 14. Les fils 12 sont alors maintenus quelques instants par des crochets afin de former des bouclettes, ou touffes, qui constitueront le velours des dalles.Fig. 1 is used to describe in more detail, by way of illustration of the present invention, the progress of a process for manufacturing textile tiles tufted. We can see schematically a tufting machine 10 powered by a multiplicity of wires 12. These wires 12 are implanted in a layer of base 14 by means of a series of needles, placed on one or more bars needles (not shown) extending over the entire width of the base layer 14, to form a tufted ply 16. This series of needles, each of which is preferably powered by a separate wire spool, pricks wires 12 to through the base layer 14. The wires 12 are then held for a few instants by hooks in order to form loops, or tufts, which will constitute the velvet of the tiles.

Chaque fois que la série d'aiguilles se rétracte, une nouvelle rangée de bouclettes de velours est formée. C'est ainsi que l'on obtient un velours bouclé. Pour obtenir un velours coupé, un couteau est placé à côté de chaque crochet afin de sectionner les bouclettes ainsi formées.Each time the needle series retracts, a new row of velvet curls is formed. This is how you get a loop pile. To obtain a cut pile, a knife is placed next to each hook in order to cut the loops thus formed.

On comprendra donc que pendant l'implantation, la couche de base 14 défile progressivement de la gauche vers la droite (par rapport à la Fig.1) dans la machine à touffeter 10, avec un pas correspondant à la largeur d'une rangée de touffes, qui sont implantées rangée après rangée sur la largeur de la couche de base 14, c'est-à-dire transversalement. Cette direction dans laquelle la couche de base 14, respectivement la nappe touffetée 16, progresse dans la machine à touffeter 10 est appelée "direction de fabrication". En général, on fabrique des nappes touffetées de grande dimension et la direction de fabrication est alors aussi la direction longitudinale de la nappe touffetée.It will therefore be understood that during the implantation, the base layer 14 gradually scrolls from left to right (compared to Fig. 1) in the tufting machine 10, with a step corresponding to the width of a row tufts, which are planted row after row across the width of the layer base 14, that is to say transversely. This direction in which the base layer 14, respectively the tufted layer 16, progresses in the tufting machine 10 is called "manufacturing direction". In general, we manufactures large tufted tablecloths and the manufacturing direction is then also the longitudinal direction of the tufted sheet.

On appréciera que, selon le présent procédé, l'implantation des fils 12 dans la couche de base 14 se fait de telle sorte que la nappe touffetée 16 comprend un motif décoratif, une ligne de guidage parallèle à la direction de fabrication de la nappe touffetée et préférablement en bordure de celle-ci, ainsi que des repères de coupe. Dans la présente variante, le motif décoratif est réalisé sur la couche de base en bandes transversales, qui ont des dimensions correspondant à deux rangées de quatre dalles indiquées 17. Ces bandes transversales sont espacées dans la direction de fabrication, ce qui laisse des marges pour compenser l'élongation éventuelle de la couche de base et pour faciliter la découpe. Sur les deux bords longitudinaux de la couche de base 14, des lignes de guidage 18 et des repères de coupe 20 sont implantés en même temps que les motifs décoratifs. Ces lignes de guidage 18 et ces repères de coupe 20 sont donc implantés rangée après rangée, de la même manière que les motifs décoratifs, et servent à indexer la nappe touffetée 16 en vue de son découpage ultérieur.It will be appreciated that, according to the present method, the implantation of the wires 12 in the base layer 14 is made so that the tufted ply 16 includes a decorative pattern, a guide line parallel to the direction of manufacture of the tufted tablecloth and preferably on the edge thereof, thus as cutting marks. In the present variant, the decorative pattern is made on the base layer in transverse bands, which have dimensions corresponding to two rows of four slabs indicated 17. These bands are spaced apart in the manufacturing direction, which leaves margins to compensate for the possible elongation of the base layer and for facilitate cutting. On the two longitudinal edges of the base layer 14, guide lines 18 and cutting marks 20 are located at the same time decorative patterns. These guide lines 18 and these reference marks section 20 are therefore placed row after row, in the same way as the decorative patterns, and serve to index the tufted tablecloth 16 for its subsequent cutting.

Comme on peut le voir, les lignes de guidage 18 sont préférablement implantées en bordure de la nappe touffetée 16. Les repères de coupe 20 sont implantés adjacents aux lignes de guidage 18, et s'étendent perpendiculairement à celles-ci afin de donner les directions de coupe transversales. En effet, les repères de coupe sont placés avant, respectivement après, une bande transversale à découper en dalles. De manière générale, les lignes de guidage 18 sont de préférence implantées de manière à indiquer la direction longitudinale de la nappe touffetée 16. Les repères de coupe 20 sont implantés à des positions prédéterminées par rapport aux motifs décoratifs et en relation avec le format des dalles 17.As can be seen, the guide lines 18 are preferably located at the edge of the tufted ply 16. The cutting marks 20 are located adjacent to the guide lines 18, and extend perpendicularly to these in order to give the transverse cutting directions. Indeed, the cutting marks are placed before, respectively after, a strip cross to cut into slabs. Generally speaking, the guide lines 18 are preferably located so as to indicate the longitudinal direction of the tufted ply 16. The cutting marks 20 are located at predetermined positions in relation to the decorative patterns and in relation to the format of the tiles 17.

Ces repères de coupe et la ligne de guidage constituent donc un système d'indexation de la nappe touffetée 16 pour sa découpe ultérieure. Comme la ligne de guidage et les repères de coupe sont implantés en même temps que le ou les motifs décoratifs, il est possible de les positionner avec une grande précision par rapport aux motifs décoratifs. Cela est visible sur la Fig.2 qui montre la bordure d'une nappe touffetée au niveau d'un repère de coupe 120 adjacent à une ligne de guidage 118. Ainsi, malgré les déformations que peut subir la nappe touffetée en raison du manque de stabilité dimensionnelle de la couche de base, les repères de coupe sont toujours positionnés de la même manière par rapport aux motifs, et fournissent donc des repères fiables permettant de découper la nappe touffetée avec une grande précision. Dans le cas de la Fig.2, on comprend bien que même si la nappe touffetée 16 subit un étirement dans le sens longitudinal, le repère de coupe 120 sera toujours en face de la pointe du triangle du motif dessiné. La présente méthode est donc particulièrement avantageuse pour la réalisation de dalles à motifs géométriques, car elle garantit une découpe précise, ce qui est nécessaire pour le raccord entre dalles.These cut marks and the guide line therefore constitute a system for indexing the tufted ply 16 for its subsequent cutting. As the guide line and the cut marks are established at the same time as the or decorative patterns, it is possible to position them with great precision with respect to decorative patterns. This can be seen in Fig. 2 which shows the edge of a tufted tablecloth at a cut mark 120 adjacent to a guide line 118. Thus, despite the deformations that may undergo the tufted web due to the lack of dimensional stability of the base layer, the cut marks are always positioned the same way relative to the patterns, and therefore provide reliable benchmarks allowing to cut the tufted tablecloth with great precision. In the case of Fig.2, it is clear that even if the tufted ply 16 undergoes a stretch in the longitudinal direction, the cutting mark 120 will always be opposite the tip of the triangle of the pattern drawn. The present method is therefore particularly advantageous for producing tiles with geometric patterns, because it guarantees a precise cut, which is necessary for the connection between slabs.

Dans la pratique, une telle nappe touffetée comprenant sur ses bordures longitudinales un système d'indexation à lignes de guidage et repères de découpe est réalisée en prévoyant dans la machine à touffeter une série d'aiguilles pour l'implantation du système d'indexation. Sur la Fig.2, le repère 120 et la ligne 118 sont obtenus en jouant sur les hauteurs de boucle lors de l'implantation afin de faire ressortir les bouclettes claires par rapport aux bouclettes de couleur sombre. La ligne 118 est obtenue en faisant ressortir, à la même position transversale, des bouclettes de couleur claire, alors qu'on fait sortir des bouclettes voisines de couleur sombre. Pour la réalisation des repères de coupe, ce n'est qu'à certain intervalles prédéterminés que l'on fait ressortir un plus grand nombre de bouclettes claires dans une même rangée.In practice, such a tufted sheet comprising on its edges longitudinal indexing system with guide lines and benchmarks cutting is carried out by providing in the tufting machine a series needles for setting up the indexing system. In Fig. 2, the mark 120 and line 118 are obtained by playing on the loop heights during the layout in order to bring out the clear curls in relation to the dark colored curls. Line 118 is obtained by highlighting, at the same transverse position, light colored loops, while doing take out neighboring dark curls. For the realization of cutting marks, it is only at certain predetermined intervals that one makes bring out more clear curls in the same row.

Une fois la nappe touffetée 16 achevée, elle est ensuite découpée dans une presse à découper (non représentée) au format des dalles 17. La presse à découper est avantageusement munie de moyens de détection optiques pour un guidage automatisé de la nappe touffetée 16 dans la presse, en vue de la découpe précise des dalles.Once the tufted sheet 16 is finished, it is then cut from a cutting press (not shown) in the format of slabs 17. The cutting is advantageously provided with optical detection means for automated guiding of the tufted ply 16 in the press, with a view to precise cutting of the tiles.

Dans la présente variante, la nappe touffetée 16 est d'abord découpée en bandes transversales, c'est à dire perpendiculaires au sens de fabrication, en se basant sur la position des repères de coupe 20. Puis, chaque bande transversale est découpée dans la direction de fabrication en se basant sur la position des lignes de guidage 18.In the present variant, the tufted ply 16 is first cut into transverse bands, i.e. perpendicular to the manufacturing direction, in based on the position of the cutting marks 20. Then, each transverse strip is cut in the direction of manufacture based on the position of the guide lines 18.

Les repères 20 et lignes de guidages sont avantageusement disposés par rapport aux motifs décoratifs des dalles dans des zones de la nappe touffetées 16 qui formeront les chutes de découpe.The marks 20 and guide lines are advantageously arranged by relative to the decorative patterns of the tiles in tufted areas of the tablecloth 16 which will form the scraps of cut.

Reste à noter qu'avant la découpe de la nappe touffetée 16, son envers, opposé au touffetage, est de préférence soumis à une enduction, pour former une couche inférieure stabilisatrice.Remain to note that before the cutting of the tufted ply 16, its reverse side, opposite to the tufting, is preferably subjected to a coating, to form a stabilizing bottom layer.
