Description

La présente invention est relative des perfection nements apportés aux machines da traitemerts aqueux, tels the teinture ou blanchiment par exemple de tissus en pièces, et elle concerne plus particulièrement des perfectionnements ar- portés aux systèmes de circulation, de pliage, de stockage et de déchargement des tissus en pièces dans de telles machiner. L'on entend par "tissus en pièces", aussi bien les tissus chaine et trame que les tissus tricotés ouverts ou en boyaux ou rectilignes.The present invention relates to improvements made to aqueous processing machines, such as dyeing or bleaching, for example, of fabrics in pieces, and it relates more particularly to improvements made to circulation, folding, storage and unloading systems. piece fabrics in such a machine. The term "piece fabrics" means both warp and weft fabrics as well as knitted fabrics, open or in gut or straight.

Les machines de teinture de tissus en pièces connt dans l'Art antérieur, qu'il s'agisse des barques de teinture à rapport de bain très long, des machines à tuyère ou à boits de débordement qui utilisent un rapport de bain long, ou des machines récentes à rapport de bain court, sont équipées de moyens destinés à assurer la circulation des pièces de tissu dans la machine et leur pliage. C'est ainsi que les barques, qui ont un rapport de bain de l'ordre de 1:20 à 1:30, sont généralement équipées, pour le pliage du tissu, d'un rouleau ovale ou triangulaire qui dépose le tissu en plis sur un plan incliné en plein bain. Toutefois, dans ce type de machines de teinture, la circulation du tissu, qui est introduit à raison d'une multiplicité de brins de faible longueur (200 m au maximum), et son déplacement jusqu'au compartiment de stockage, sont assurés par le bain de teinture, qui perturbe le pliage et qui provoque la formation de boucles et de noeuds dans le tissu, qui genent la circulation de celui-ci et cnt une incidence défavorable sur la qualité de la teinture.Machines for dyeing fabrics in pieces known in the prior art, whether they are dyeing boats with a very long bath ratio, nozzle or overflow box machines which use a long bath ratio, or recent machines with short bath ratio, are equipped with means intended to ensure the circulation of the pieces of fabric in the machine and their folding. This is how the boats, which have a bath ratio of the order of 1:20 to 1:30, are generally equipped, for folding the fabric, with an oval or triangular roller which deposits the fabric in folds on an incline in the middle of the bath. However, in this type of dyeing machine, the circulation of the fabric, which is introduced at the rate of a multiplicity of short strands (200 m maximum), and its movement to the storage compartment, are ensured by the dye bath, which disrupts folding and causes the formation of loops and knots in the fabric, which impede the circulation of the latter and adversely affect the quality of the dye.

Dans les machines de teinture à tuyère ou à boite de débordement classiques, qui utilisent un rapport de bain de l'ordre de 1:8 à 1:10, le déplacement du tissu est également assuré par le bain de teinture, le pliage étant réalisé à la sortie du système de teinture à l'aide de moyens mécaniques tels que coude, cône, perforé ou non, plan incliné ou en utilisant l'espace intérieur meme de la machine ; dans ces machines, l'intervention du bain de teinture pour assurer le déplacement du tissu a également pour effet de perturber le pliage et d'etre à l'origine de la formation de boucles et de noeuds qui genent la circulation du tissu et altèrent la gu lité de la teinture.In conventional nozzle or overflow box dyeing machines, which use a bath ratio of the order of 1: 8 to 1:10, the movement of the fabric is also ensured by the dye bath, folding being carried out. at the outlet of the dyeing system using mechanical means such as elbow, cone, perforated or not, inclined plane or by using the same interior space of the machine; in these machines, the intervention of the dye bath to ensure the movement of the fabric also has the effect of disturbing the folding and of being at the origin of the formation of loops and knots which hinder the circulation of the fabric and alter the quality of the dye.

Les machines à rapport de bain très court (1:1,5 à 1:2) du type des machines qui font l'objet de la Demande de Brevet n° 77 19068 du 22 Juin 1977, de la Demande de certificat d'Addition n° 77 19747 du 28 Juin 1977 et de la Demande de Brevet n° 77 38577 du 21 Décembre 1977, au nom de la Demanderesse, permettent un stockage du tissu sensiblement plus satisfaisant que les autres machines de teinture connues dans l'Art antérieur, en ce que la matière textile y est stockée en dehors du bain et n'est, de ce fait, soumise à aucune perturbation due au bain, puisque ce n'est plus ce dernier qui fait avancer le tissu, celui-ci étant déplacé uniquement par des moyens mécaniques. Toutefois, dans le cas du traitement de tissus légers et/ou du traitement dans la machine de plusieurs brins à la fois, par un même système de teinture, avec le stockage du tissu dans un meme compartiment de stockage, il peut encore néanmoins se former des boucles et des noeuds dans le tissu, qui gênent la circulation de ce dernier et altèrent la qualité de la teinture, malgré l'emploi de moyens mécaniques, qui sont généralement constitués soit par la rotation du compartiment de stockage, soit par un plan incliné sur lequel tombe le stock de tissu, qui en est déchargé par pivotement du plan incliné.Machines with a very short bath ratio (1: 1.5 to 1: 2) of the type of machines which are the subject of Patent Application No. 77 19068 of June 22, 1977, of the Request for Certificate of Addition n ° 77 19747 of June 28, 1977 and of Patent Application n ° 77 38577 of December 21, 1977, in the name of the Applicant, allow storage of the fabric significantly more satisfactory than the other dyeing machines known in the prior art, in that the textile material is stored there outside of the bath and is therefore not subject to any disturbance due to the bath, since it is no longer the latter which advances the fabric, the latter being moved only by mechanical means. However, in the case of the treatment of light fabrics and / or the treatment in the machine of several strands at the same time, by the same dyeing system, with the storage of the fabric in the same storage compartment, it can still nevertheless be formed. loops and knots in the fabric, which impede the circulation of the latter and alter the quality of the dye, despite the use of mechanical means, which are generally formed either by the rotation of the storage compartment, or by an inclined plane on which falls the stock of fabric, which is discharged by pivoting the inclined plane.

De plus, meme dans des machines dans lesquelles le déplacement du tissu n'est pas provoqué par le bain de teinture, comme c'est le cas dans les machines à rapport de bain très court connues mentionnées plus haut, le bain de teinture vient néanmoins interférer avec le pliage'et le stockage du tissu, pour les gener : en effet, le système de teinture est placé à la descente du tissu, juste avant le retour de ce dernier dans le compartiment de stockage, en sorte que le bain projeté hors du système de teinture situé à la descente du tissu, perturbe, même dans de telles machines, les opérations de pliage, notamment dans le cas où deux brins sont en circulation dans le même système, dans lequel le bain de teinture projeté hors du système de teinture situé à la descente du tissu peut provoquer la séparation des deux brins, lors des opérations de pliage et de stockage, une telle séparation pouvant entrainer, à la remontée, la formation de boucles ou de noeuds.In addition, even in machines in which the displacement of the fabric is not caused by the dye bath, as is the case in the very short known bath ratio machines mentioned above, the dye bath nevertheless comes interfere with folding and fabric storage, for gener: in fact, the dye system is placed at the descent of the fabric, just before the return of the latter in the storage compartment, so that the bath projected out of the dyeing system located at the descent of the fabric, disrupts, even in such machines, the folding operations, in particular in the case where two strands are circulating in the same system, in which the dye bath sprayed out of the dye located at the descent of the fabric can cause the separation of the two strands, during folding and storage operations, such separation can lead, on the rise, to the formation of loops or knots.

Pour minimiser les perturbations enrésultant sur le pliage, on a tendance àreduire le débit du bain dans le système de teinture en vue de l'optimisation des opérations de pliage et de stockage, mais au détriment des opérations de teinture.To minimize the disturbances resulting from folding, there is a tendency to reduce the flow rate of the bath in the dyeing system with a view to optimizing the folding and storage operations, but to the detriment of the dyeing operations.

Par ailleurs, dans les machines de traitement aqueux, et notamment de teinture, connues dans l'Art antérieur, le déchargement du stock de tissu traité est réalisé à l'aide d'un anneau et d'un rouleau de déchargement. Toutefois, la solution existante n'est satisfaisante que pour autant que les dispositifs de déchargement du tissu traité ne déchargent qu'un seul brin, car au-delà d'un brin, les brins de tissu à décharger s'amalgament en formant des torsions qui gênent considérablement le déchargement et peuvent même provoquer son arrêt.Furthermore, in aqueous treatment machines, and in particular dyeing machines, known in the prior art, the stock of treated fabric is unloaded using a ring and an unloading roller. However, the existing solution is only satisfactory insofar as the devices for unloading the treated fabric unload only one strand, because beyond one strand, the strands of fabric to be unloaded amalgamate forming twists. which considerably hamper unloading and can even cause it to stop.

La présente invention a en conséquence pour but de pourvoir à une machine de traitement aqueux, notamment de teinture, de blanchiment ou autres, des tissus en pièces, qui répond mieux aux nécessités de la pratique que les machines visant aux mêmes buts antérieurement connues, notamment en ce qu'elle est pourvue de systèmes de circulation, de pliage, de stockage et de déchargement qui éliminent les inconvénients des systèmes correspondants connus dans l'Art antérieur.The present invention therefore aims to provide an aqueous treatment machine, in particular for dyeing, bleaching or other, fabrics in pieces, which better meets the needs of practice than machines for the same purposes previously known, in particular in that it is provided with circulation, folding, storage and unloading systems which eliminate the drawbacks of the corresponding systems known in the prior art.

Selon un mode de réalisation avantageux de la machine objet de la présente invention, le dispositif de réception et de guidage du tissu vers le compartiment de stockage, est constitué par une boite en forme de J.According to an advantageous embodiment of the machine object of the present invention, the device for receiving and guiding the fabric towards the storage compartment, is constituted by a J-shaped box.

Selon encore un autre mode de réalisation de la machine objet de la présente invention, cette dernière comporte un deuxième système de teinture monté sur le parcours de retour du tissu vers le compartiment de stockage, entre lesdits moyens mécaniques de retour du tissu et le dispositif de réception et de guidage du tissu vers le compartiment de stockage.According to yet another embodiment of the machine which is the subject of the present invention, the latter comprises a second dyeing system mounted on the path for returning the fabric to the storage compartment, between said mechanical means for returning the fabric and the device for receiving and guiding the fabric to the storage compartment.

Conformément à l'invention, des moyens de pliage du tissu sont associés aux moyens mécaniques de retour du tissu susdits. , .According to the invention, means for folding the fabric are associated with the mechanical means for returning the aforementioned fabric. ,.

Egalement conformément à l'invention, dans le cas où la machine objet de la présente invention, comprend un premier système de teinture disposé à la remontée du tissu et un deuxième système de teinture disposé à la descente du tissu, elle peut également être pourvue de moyens de pliage, qui, dans ce cas, sont intercalés entre le deuxième système de teinture monté à la descente du tissu, et le dispositif de réception et de guidage du tissu vers le compartiment de stockage.Also in accordance with the invention, in the case where the machine which is the subject of the present invention comprises a first dyeing system arranged at the ascent of the fabric and a second dyeing system arranged at the descent of the fabric, it can also be provided with folding means, which, in this case, are interposed between the second dyeing system mounted when the fabric is lowered, and the device for receiving and guiding the fabric to the storage compartment.

Selon un autre mode de réalisation de la machine objet de la présente invention, les moyens de pliage du tissu font partie intégrante des moyens de retour du tissu dans le compartiment de stockage.According to another embodiment of the machine which is the subject of the present invention, the means for folding the fabric form an integral part of the means for returning the fabric to the storage compartment.

Conformément à une disposition avantageuse de ce mode de réalisation, les moyens intégrés de retour et de pliage du tissu sont constitués par un rouleau moteur de section non cylindrique, et en particulier de section ovale, polygonale, ou par un disque plat, ou bien encore ils sont constitués par un rouleau cylindrique d'axe incliné sur l'horizontale dont le flasque opposé à celui associé à l'extrémité du rouleau qui repose sur l'horizontale, peut éventuellement être dissocié de l'extrémité correspondante du rouleau et être disposé sur l'axe horizontal sur lequel le rouleau est incliné.In accordance with an advantageous arrangement of this m ode embodiment, the integrated means for return and folding the fabric are constituted by a drive roller non-cylindrical section, in particular oval, polygonal, or a flat disk, or still they are constituted by a cylindrical roller with an axis inclined to the horizontal, the flange opposite to that associated with the end of the roller which rests on the horizontal, can optionally be dissociated from the corresponding end of the roller and be arranged on the horizontal axis on which the roller is tilted.

Selon un autre mode de réalisation de la machine objet de la présente invention, les moyens de pliage du tissu sont distincts des moyens de retour du tissu dans le compartiment de stockage.According to another embodiment of the machine which is the subject of the present invention, the means for folding the fabric are distinct from the means for returning the fabric to the storage compartment.

Dans ce cas, conformément à une disposition avantageuse de ce mode de réalisation, les moyens de retour du tissu dans le compartiment de stockage sont constitués par un rouleau moteur cylindrique d'appel du tissu, auquel sont associés des moyens de pliage du tissu, lesquels sont avantageusement constitués, conformément à l'invention, par un anneau ou par un double-entonnoir animé d'un mouvement circulaire ou d'un mouvement de.va-et-vient avantageusement linéaire. ces moyens de pliage sont avantageusement montés à la suite du rouleau d'appel. Ils peuvent toutefois également être montés avant le rouleau d'appel, c'est-à-dire entre la sortie du système de teinture disposé à la remontée du tissu et le rouleau d'appel.In this case, in accordance with an advantageous arrangement of this embodiment, the means for returning the fabric to the storage compartment are constituted by a cylindrical driving roller for drawing the fabric, with which are means for folding the fabric, which are advantageously constituted, in accordance with the invention, by a ring or by a double funnel animated with a circular movement or with a movement back and forth advantageously linear. these folding means are advantageously mounted following the take-up roller. However, they can also be mounted before the take-up roller, that is to say between the outlet of the dyeing system arranged at the raising of the fabric and the take-up roller.

Conformément à l'invention, dans le cas où la machine objet de la présente invention est équipée de deux systèmes de teinture montés respectivement à la remontée et à la descente du tissu, de part et d'autre des moyens mécaniques de retour du tissu vers le compartiment de stockage, tels que rouleau cylindrique par exemple, elle peut également être équipée des moyens de pliage précités, tels qu'anneau ou double-entonnoir, par exemple, ces moyens de pliage étant alors avantageusement prévus entre la sortie du deuxième système de teinture et l'entrée du dispositif de réception et de guidage du tissu vers le compartiment de stockage.In accordance with the invention, in the case where the machine which is the subject of the present invention is equipped with two dyeing systems mounted respectively for raising and lowering the fabric, on either side of the mechanical means for returning the fabric to the storage compartment, such as a cylindrical roller for example, it can also be equipped with the aforementioned folding means, such as a ring or double funnel, for example, these folding means then being advantageously provided between the outlet of the second system of dyeing and entry of the fabric receiving and guiding device to the storage compartment.

Selon un mode de réalisation avantageux de la boite en forme de J de réception et de guidage du tissu vers le compartiment de stockage, cette dernière est équipée d'un dispa- sitif de sécurité qui détecte un stockage trop haut du tissu dans la boite en forme de J et provoque l'arrêt des moyens de retour du tissu et éventuellement l'inversion de leur sens de fonctionnement jusqu'à l'évacuation du trop-plein de ladite boite.According to an advantageous embodiment of the box in the form of a J for receiving and guiding the fabric towards the storage compartment, the latter is equipped with a safety device which detects too high storage of the tissue in the J-shaped box and causes the stopping of the means for returning the fabric and possibly reversing their direction of operation until the overflow from said box is removed.

Selon encore un autre mode de réalisation avantageux de la machine objet de la présente invention, celle-ci est pourvue d'un dispositif de sécurité associé au compartiment de stockage, qui comporte des moyens de détection de toute anomalie de l'avancement du stock de tissu dans ledit compartiment et des moyens pour le réglage de la vitesse de déplacement du stock de tissu dans le ou les compartiments de stockage.According to yet another advantageous embodiment of the machine object of the present invention, it is provided with a safety device associated with the storage compartment, which comprises means for detecting any anomaly in the progress of the stock of tissue in said compartment and means for adjusting the speed of movement of the tissue stock in the storage compartment (s).

Conformément à une disposition avantageuse de l'invention, un tel dispositif de sécurité est constitué par une paroi pivotante associée à un interrupteur de fin de course, lui-même éventuellement associé à un variateur de vitesse qui règle la vitesse de fonctionnement des moyens mécaniques de déplacement du tissu associés au compartiment de stockage, laquelle paroi pivotante détecte le passage du stock de tissu en plis, prêt à la remontée, et dont le pivotement provoque l'arrêt et/ou le réglage de la vitesse de fonctionnement desdits moyens de déplacement du tissu.In accordance with an advantageous arrangement of the invention, such a safety device is constituted by a pivoting wall associated with a limit switch, itself possibly associated with a variable speed drive which regulates the operating speed of the mechanical means of movement of the fabric associated with the storage compartment, which pivoting wall detects the passage of the stock of folded fabric, ready for the ascent, and whose pivoting causes the stop and / or the adjustment of the operating speed of said means for moving the tissue.

Selon encore un autre mode de réalisation de la machine objet de l'invention, la circulation'du tissu et l'écoulement du bain, de teinture par exemple, dans le système de teinture ou autre, ont lieu à contre-courant l'un de l'autre.According to yet another embodiment of the machine which is the subject of the invention, the circulation of the fabric and the flow of the bath, of dye for example, in the dye system or the like, take place against the current one the other.

Conformément à l'invention, les moyens de déchargement du stock de tissu traité, de la machine, comprennent autant d'anneaux qu'il y a de brins à décharger et au moins un rouleau moteur de déchargement monté en aval des anneaux, et sont caractérisés en ce qu'ils sont en outre pourvus d'au moins un organe apte à être entraîné en rotation ou en pivotement en présence d'une torsion pour défaire celle-ci, et d'au moins un bac de réception du ou des brins de tissu déchargé(s).According to the invention, the means for discharging the stock of treated fabric from the machine comprises as many rings as there are strands to be discharged and at least one unloading drive roller mounted downstream of the rings, and are characterized in that they are further provided with at least one member capable of being rotated or pivoted in the presence of a twist to undo it, and at least one container for receiving the strand (s) of discharged tissue (s).

Selon une disposition avantageuse de ce mode de réalisation, l'organe apte à être entrainé en rotation ou en pi- votement, est constitué par un entonnoir solidaire de la machine, auquel est ou sont solidarisés l'anneau ou les anneaux destinés au passage d'un brin du tissu, lequel entonnoir est entrainé en rotation ou en pivotement par la détection de la présence de torsions et s'arrête en l'absence de passage de torsions.According to an advantageous arrangement of this embodiment, the member capable of being rotated or tilted v otement, is constituted by a funnel integral with the machine, to which is or are secured the ring or rings intended for the passage of a strand of fabric, which funnel is rotated or pivoted by detecting the presence of twists and stops when no twists pass.

Selon une autre disposition avantageuse de ce mode de réalisation, l'organe apte à etre entraîné en rotation ou en pivotement est constitué par deux tiges solidaires entre elles d'une part et de l'anneau ou des anneaux d'autre part.According to another advantageous arrangement of this embodiment, the member capable of being driven in rotation or in pivoting is constituted by two rods integral with each other on the one hand and the ring or rings on the other hand.

Selon encore une autre disposition avantageuse de ce mode de réalisation, l'organe apte à être entrainé en rotation ou en pivotement est constitué par une plaque rotative ou pivotante sur laquelle est monté au moins un bac de réception du ou des brins de tissu déchargé(s), laquelle plaque porte une tige axiale qui supporte à son extrémité supérieure, respectivement l'anneau ou les anneaux et le ou les rouleaux moteurs de déchargement, l'entraînement en rotation de l'ensemble étant déterminé par la détection de la présence de . torsions.According to yet another advantageous arrangement of this embodiment, the member capable of being driven in rotation or in pivoting consists of a rotary or pivoting plate on which is mounted at least one container for receiving the strand (s) of unloaded fabric ( s), which plate carries an axial rod which supports at its upper end, respectively the ring or rings and the unloading drive roller or rollers, the rotational drive of the assembly being determined by detecting the presence of . twists.

Conformément à l'invention, le bac de réception du tissu déchargé comprend, dans le cas de l'application du dispositif de déchargement conforme à l'invention, au déchargement d'une pluralité de brins, autant de compartiments que de brins à décharger, ou bien il est remplacé par une pluralité de chariots indépendants contigüs.In accordance with the invention, the tray for receiving the unloaded fabric comprises, in the case of the application of the unloading device according to the invention, when unloading a plurality of strands, as many compartments as strands to be unloaded, or it is replaced by a plurality of contiguous independent carriages.

L'on comprendra aisément que le bac de réception du tissu, ou compartiment de stockage, peut etre multiple et notamment comporter plusieurs compartiments concentriques ou superposés comportant soit un seul rouleau d'appel coopérant avec les compartiments multiples, soit autant de rouleaux d'appel que de compartiments.It will be easily understood that the tissue receiving tray, or storage compartment, can be multiple and in particular comprise several concentric or superimposed compartments comprising either a single roll of appeal cooperating with the multiple compartments, or as many rolls of call than compartments.

Il doit etre bien entendu, toutefois, que ces dessins et les parties descriptives correspondantes, sont donnés uniquement à titre d'illustration de l'objet de l'invention, dont ils ne constituent en aucune manière une limitation.It should be understood, however, that these drawings and the corresponding descriptive parts, are given solely by way of illustration of the subject of the invention, of which they do not in any way constitute a limitation.

Bien qu'on ait représenté très schématiquement aux dessins, et notamment aux figures 1 à 4, 7-et 8, une machine de traitement aqueux, et plus particulièrement de teinture de tissus en pièce, à tuyère ou à injecteur 1, à boite de débordement 2, à tube de guidage et d'imprégnation 3, et comportant au moins un compartiment de stockage 4 réalisé sous forme de couronne, rotatif autour de son axe vertical et perforé au moins dans ses parties basses, dont les caractéristiques sont celles de la machine conforme à la Demande de Brevet n° 77 19068 du 22 Juin 1977 et à la Demande de Certificat d'Addition n° 77 19747 du 28 Juin 1977, déjà mentionnées, à rapport de bain très court, l'on comprendra cependant aisément que les systèmes de circulation, de pliais, de stockage et de déchargement qui font l'objet de la présente invention, conviennent à tous les types de machines de traitement aqueux de tissus en pièce, c'est-à-dire aussi bien aux machines susdites à rapport de bain très court, dont les nouveaux systèmes conformes à l'invention améliorent encore le fonctionnement et les performances, qu'aux machines à rapport de bain long ou très long. A noter que ledit ou lesdits compartiments de stockage est ou sont montés à l'intérieur d'un cylindre fixe 35.Although there has been shown very schematically in the drawings, and in particular in FIGS. 1 to 4, 7 and 8, an aqueous treatment machine, and more particularly for dyeing fabrics in the piece, with a nozzle or with an injector 1, with a overflow 2, with guide and impregnation tube 3, and comprising at least one storage compartment 4 produced in the form of a crown, rotatable around its vertical axis and perforated at least in its lower parts, the characteristics of which are those of the machine conforms to Patent Application n ° 77 19068 of June 22, 1977 and to the Certificate Request Addition n ° 77 19747 of June 28, 1977, already mentioned, with a very short bathing ratio, it will however be easily understood that the circulation, folding, storage and unloading systems which are the subject of the present invention, suitable for all types of aqueous piece processing machines, that is to say both to the above machines with very short bath ratio, whose new systems according to the invention further improve the operation and performance, than with machines with a long or very long bath ratio. Note that said storage compartment (s) is or are mounted inside a fixed cylinder 35.

Conformément à la présente invention, le système de teinture qui peut comprendre, à titre d'exemple non limitatif, une tuyère ou une rampe d'injecteurs 1, un tube de guidage et d'imprégnation 3, une boite de débordement 2, est monté à la remontée du tissu 5, à proximité de sa sortie du compartiment de stockage, désigné d'une façon générale par la référence 4. Une telle disposition présente de grands avantages par rapport aux machines de l'Art antérieur où le système de teinture se trouve à la descente du tissu, c'est-à-dire à proximité du compartiment de stockage, et où le bain projeté hors du système de teinture, interfère avec le pliage du tissu et rend le pliage et le stockage erratiques, notamment dans le cas où deux brins sont en circulation dans le même système de teinture pour aboutir dans un même compartiment de stockage. Au contraire, dans la machine conforme à 1,'invention, dans laquelle le système de teinture est situé à la remontée du tissu, c'est-à-dire avant les moyens de retour du tissu vers le compartiment de stockage, le bain de teinture sortant du système de teinture s'écoule ou est projeté sur le tissu 5 à sa sortie du compartiment de stockage 4, en sorte que lorsqu'il entre dans la zone de pliage et de stockage, il n'y a plus possibilité d'interférence du bain avec le pliage du tissu.In accordance with the present invention, the dyeing system which may comprise, by way of nonlimiting example, a nozzle or an injector manifold 1, a guide and impregnation tube 3, an overflow box 2, is mounted when the fabric 5 is raised, near its exit from the storage compartment, generally designated by the reference 4. Such an arrangement has great advantages compared to the machines of the prior art where the dyeing system is found at the descent of the fabric, that is to say near the storage compartment, and where the bath projected outside the dyeing system, interferes with the folding of the fabric and makes folding and storage erratic, especially in the case where two strands are circulating in the same dyeing system to end up in the same storage compartment. On the contrary, in the machine according to 1, the invention, in which the dyeing system is located at the rise of the fabric, that is to say before the means for returning the fabric to the storage compartment, the dye coming out of the dye system flows or is projected onto the fabric 5 as it leaves the storage compartment 4, so that when it enters the folding and storage area, there is no longer any possibility of interference of the bath with the folding of the fabric.

A noter que la circulation du tissu 5 dans le système de teinture a lieu à contre-courant de la circulation du bain de teinture, dans l'exemple considéré. Il est cependant possible d'orienter la tuyère 1 de manière à provoquer la circulation du tissu et du bain dans le même sens,c'est-à-dire à faire remonter le bain en même temps que le tissu, dans la machine.Note that the circulation of the fabric 5 in the dyeing system takes place against the flow of the circulation of the dye bath, in the example considered. It is however possible to orient the nozzle 1 so as to cause the circulation of the fabric and the bath in the same direction, that is to say bring the bath up at the same time as the fabric in the machine.

A sa sortie de la boite de débordement 2, l'avancement du tissu 5 est assuré par un rouleau d'appel moteur. Selon l'un des modes de réalisation de l'invention, le rouleau d'appel moteur joue en même temps le rôle de dispositif de pliage ; il est alors nécessaire de donner à ce rouleau une forme autre que cylindrique : cf. par exemple les figures 2, 4, 5 et 7 où le rouleau d'appel moteur 6 présente une section ovale, étant entendu qu'un rouleau présentant une section polygonale, par exemple triangulaire, permettrait d'obtenir un pliage comparable. La section non circulaire du rouleau 6 provoque la formation de plis réguliers. Ces plis peuvent être obtenus, selon un autre mode de réalisation de l'invention en associant un rouleau d'appel moteur 7 cylindrique, qui joue uniquement le rôle de rouleau de déplacement du tissu à sa sortie du système de teinture, à un dispositif de formation de plis qui peut être constitué par un anneau (non représenté) ou par un double entonnoir 8 (cf. figure 6) dans lequel passe le tissu en aval du rouleau d'appel 7. Conformément à l'invention, pour obtenir la formation de plis réguliers, il est avantageux que le dispositif tel qu'anneau ou double entonnoir, soit animé d'un mouvement circulaire ou d'un mouvement de va-et-vient, ce dernier de préférence linéaire. On obtient, avec ce dispositif à rouleau d'appel cylindrique et à système de formation de plis tel qu'un anneau ou un double entonnoir 8, une formation dé plis plus réguliers encore, en disposant l'anneau ou le double entonnoir 8 avant le rouleau d'appel 7,. entre la boite de débordement et ce dernier, car une telle disposition confère au tissu sur le rouleau d'appel 7 un double mouvement d'avancement et de va-et-vient.At its exit from the overflow box 2, the advancement of the fabric 5 is ensured by a motor call roller. According to one of the embodiments of the invention, the motor take-up roller simultaneously plays the role of folding device; it is then necessary to give this roller a shape other than cylindrical: cf. for example Figures 2 , 4 , 5 and 7 where the motor call roller 6 has an oval section, it being understood that a roller having a polygonal section, for example triangular, would make it possible to obtain a comparable folding. The non-circular section of the roller 6 causes the formation of regular folds. These folds can be obtained, according to another embodiment of the invention by associating a cylindrical drive roll 7, which only acts as a roll for moving the fabric as it leaves the dyeing system, with a device for formation of folds which can be constituted by a ring (not shown) or by a double funnel 8 (cf. FIG. 6) in which the fabric passes downstream of the take-up roller 7. According to the invention, to obtain the formation with regular folds, it is advantageous for the device such as a ring or double funnel to be driven in a circular movement or in a reciprocating movement, the latter preferably linear. One obtains, with this cylindrical roll call device and pleat forming system such as a ring or a double funnel 8, a formation of even more regular folds, by arranging the ring or the double funnel 8 before the call roller 7 ,. between the overflow box and the latter, because such an arrangement gives the fabric on the take-up roller 7 a double movement of forward and back and forth.

Conformément à l'invention, la formation de plis peut être obtenue par d'autres moyens que ceux qui viennent d'être décrits, et notamment en utilisant un disque plat 9 tel que celui représenté à la figure 5, ou en utilisant un rouleau cylindrique incliné sur l'horizontale. Dans ce dernier cas, des gorges doivent être ménagées sur le rouleau, au voisinage de ses extrémités, pour assurer le maintien en place du tissu sur le rouleau. Il n'est pas nécessaire de ménager des gorges au voisinage des extrémités du roulean lorsqu'on utilise un rouleau cylindrique incliné sur l'horizontale, dont les flasques sont disposés parallèlement entre eux dans des plans perpendiculaires à l'axe horizontal sur lequel le rouleau est incliné, les flasques jouant alors le rôle de maintien du tissu précédemment dévolu aux gorges. Les plis formés par le dispositif de pliage conforme à l'invention (6 des figures 1,2,4 et 7 ; 9 de la figure 5 ; 7-8 de la figure 6, ou des dispositifs équivalents) tombent dans la boite en forme de J, 10, qui est disposée immédiatement au-dessous du dispositif de pliage, dans laquelle ils sont emmagasinés régulièrement sur toute la largeur de cette dernière, sans subir de modification, puisqu'il n'y a aucune circulation de bain. La partie inférieure du J de la boite en forme de J, 10, débouche dans le compartiment de stockage 4 dans lequel elle dépose le tissu en plis 11 qu'elle a commencé à emmagasiner. Dans le compartiment de stockage 4, le tissu conserve pendant toute sa phase de stockage, sa forme en plis 11 sans perturbations, puisqu'il n'y a aucune circulation de bain. Dans certains cas, la formation de plis dans la boite 10 en forme de J est suffisamment régulière, du fait de la conformation particulière de ladite boite, pour pouvoir renoncer à la disposition de moyens de pliage particuliers, le rouleau d'appel 7 étant alors choisi de forme cylindrique.According to the invention, the formation of folds can be obtained by other means than those which have just been described, and in particular by using a flat disc 9 such as that shown in FIG. 5, or by using a cylindrical roller. tilted horizontally. In the latter case, grooves must be provided on the roller, in the vicinity of its ends, to keep the fabric in place on the roller. It is not necessary to provide grooves in the vicinity of the ends of the roller when using a cylindrical roller inclined on the horizontal, the flanges of which are arranged parallel to each other in planes perpendicular to the horizontal axis on which the roller is inclined, the flanges then playing the role of maintaining the tissue previously assigned to the grooves. The folds formed by the folding device according to the invention (6 of Figures 1,2,4 and 7 ; 9 of Figure 5; 7-8 of Figure 6, or equivalent devices) fall into the box in shape J, 10, which is arranged immediately below the folding device, in which they are stored regularly over the entire width of the latter, without undergoing modification, since there is no bath circulation. The lower part of the J of the J-shaped box, 10, opens into the storage compartment 4 in which it deposits the folded fabric 11 that it has started to store. In the storage compartment 4, the fabric retains, during its entire storage phase, its folded shape 11 without disturbances, since there is no bath circulation. In certain cases, the formation of folds in the J-shaped box 10 is sufficiently regular, due to the particular conformation of said box, to be able to dispense with the provision of particular folding means, the take-up roller 7 then being chosen cylindrical.

La remontée du tissu dans le système de teinture, pour subir un nouveau traitement dans la machine, est obtenue non pas à l'aide du bain de teinture lui-meme, comme dans l'Art antérieur, mais essentiellement par les moyens mécaniques de retour du tissu décrits dans ce qui précède.The raising of the fabric in the dyeing system, to undergo a new treatment in the machine, is obtained not using the dyeing bath itself, as in the prior art, but essentially by the mechanical return means. of the fabric described in the above.

Du fait qu'il n'y a aucune interférence entre le bain et le processus de pliage, on obtient une continuité et une rapidité satisfaisantes du déplacement, du pliage et du stockage du tissu dans la machine conforme à la présente invention, et, par suite, des vitesses de circulation extrêmement élevées du tissu dans la machine. La disposition du système de teinture à la remontée du tissu permet en outre d'aua- menter de façon optimale du point de vue des exigences de la teinture, les débits du bain de teinture dans le système de teinture de manière à améliorer la qualité de la teinture dans une mesure impossible à atteindre avec les techniques de l'Art antérieur, l'amélioration de la qualité de la teinture à chaque passage du tissu dans la machine étant de nature à réduire le nombre de ces passages et, par voie de conséquence, à réduire le prix de revient des opérations réalisées dans la machine et à augmenter le rendement de cette dernière.Since there is no interference between the bath and the folding process, satisfactory continuity and rapidity of movement, folding and storage of the fabric in the machine according to the present invention are obtained, and, by as a result, extremely high speeds of circulation of the fabric in the machine. The arrangement of the dyeing system for raising the fabric also makes it possible to increase optimally from the point of view of the requirements of the dyeing, the dye bath flow rates in the dyeing system so as to improve the quality of the dye to an extent impossible to achieve with the techniques of the prior art, improving the quality of the dye each time the fabric in the machine being such as to reduce the number of these passages and, consequently, to reduce the cost price of the operations carried out in the machine and to increase the output of the latter.

Il y a lieu de mentionner, en outre, que le dispositif de circulation, pliage et stockage conforme à l'invention, permet d'augmenter considérablement la capacité de la machine, en permettant de réaliser simultanément le traitement aqueux de plusieurs brins de tissu dans un seul et même système de teinture et leur stockage dans un seul et même compartiment. Toutes les tentatives faites avec les machines conformes à l'Art antérieur, pour faire circuler plus d'un brin à la fois dans un seul et même système de teinture, et réaliser le stockage dans un seul et même compartiment, se sont soldées par des échecs, en particulier, lorsque les brins soumis au traitement étaient des tissus légers ou des tissus à mailles: en effet, la circulation de plusieurs brins de tissus légers dans un même système de teinture, puis dans un même système de pliage et de stockage, entraine la formation de boucles et de noeuds qui non seulement gênent et parfois même empêchent la circulation des brins, en provoquant l'arrêt de la machine, mais nuisent en outre à la qualité du traitement appliqué, de teinture en particulier. Or, les perfectionnements introduits conformément à la présente invention permettent d'obtenir une qualité parfaite du pliage et du stockage, non seulement dans le cas d'un seul brin de tissu, mais, surtout, lorsque deux brins, et même trois, sont simultanément en circulation à travers le même système de teinture et aboutissent, après pliage, dans le même compartiment de stockage. En multipliant le nombre de brins traités, pliés et stockés simultanément, on obtient une augmentation considérable de la capacité de la machine conforme à l'invention et, par suite, de son rendement, en même temps qu'une réduction sensi- blé du prix de revient des traitements réalisés dans la machine.It should also be mentioned that the circulation, folding and storage device according to the invention makes it possible to considerably increase the capacity of the machine, by making it possible to simultaneously carry out the aqueous treatment of several strands of fabric in one and the same dyeing system and their storage in one and the same compartment. All the attempts made with machines conforming to the prior art, to circulate more than one strand at a time in a single dyeing system, and to carry out storage in a single and same compartment, have resulted in failures, in particular, when the strands subjected to treatment were light fabrics or knitted fabrics: in fact, the circulation of several strands of light fabrics in the same dyeing system, then in the same folding and storage system, causes the formation of loops and knots which not only hamper and sometimes even prevent the movement of the strands, causing the machine to stop, but also adversely affect the quality of the treatment applied, dyeing in particular. However, the improvements introduced in accordance with the present invention make it possible to obtain perfect quality of folding and storage, not only in the case of a single strand of fabric, but, above all, when two strands, and even three, are simultaneously circulating through the same dyeing system and end up, after folding, in the same storage compartment. By multiplying the number of strands treated, folded and stored simultaneously, a considerable increase is obtained in the capacity of the machine according to the invention and, consequently, in its efficiency, at the same time as a significant reduction. wheat of the cost price of the treatments carried out in the machine.

Il peut être avantageux, pour certains traitements aqueux, de teinture notamment, appliqués à certaines catégories de tissus, de pouvoir disposer de deux systèmes de teinture dans une même machine. En pareil cas, représenté schématiquement à la figure 8, le premier système de teinture 1, est disposé à la remontée du tissu 5, comme dans le mode de réalisation précédemment décrit, tandis que le deuxième système de teinture 33 est disposé à la descente du tissu, précédant la boite 10 en forme de J de réception et de guidage du tissu vers le compartiment de stockage 4, c'est-à-dire que les systèmes de teinture 1 et 33 sont disposés de part et d'autre du rouleau d'appel moteur cylindrique 34 qui a pour rôle d'appeler le tissu à sa sortie du système de teinture 1, pour le ramener au compartiment de stockage 4 par l'intermédiaire de la boite en forme de J, 10 et du système de teinture 33.It may be advantageous, for certain aqueous treatments, in particular of dyeing, applied to certain categories of fabrics, to be able to have two dyeing systems in the same machine. In such a case, represented diagrammatically in FIG. 8, the first dyeing system 1 is disposed on the rise of the fabric 5, as in the embodiment described above, while the second dyeing system 33 is arranged on the descent of the fabric, preceding the J-shaped box 10 for receiving and guiding the fabric towards the storage compartment 4, that is to say that the dyeing systems 1 and 33 are arranged on either side of the roller d call cylindrical motor 34 which has the role of calling the fabric at its exit from the dyeing system 1, to bring it back to the storage compartment 4 via the J-shaped box, 10 and the dyeing system 33 .

Une telle machine, équipée de deux systèmes de teinture respectivement à la remontée et à la descente du tissu, peut, si on le désire, être équipée de moyens de pliage, tels qu'anneau ou tels que le double-entonnoir représenté à la figure 6, lesquels sont alors interposés entre la sortie du système de teinture 33 et l'entrée de la boite 10 en forme de J.Such a machine, equipped with two dyeing systems respectively for raising and lowering the fabric, can, if desired, be equipped with folding means, such as a ring or such as the double funnel shown in the figure. 6, which are then interposed between the outlet of the dyeing system 33 and the inlet of the J-shaped box 10.

La disposition de deux systèmes de teinture, l'un à la remontée du tissu et l'autre à la descente du tissu, a pour résultat d'augmenter l'effet d'imprégnation du tissu en bain de teinture, au cours d'une même opération, sans présenter les inconvénients des machines connues, grâce à la disposition d'un système de teinture à la remontée du tissu.The arrangement of two dyeing systems, one at the ascent of the fabric and the other at the descent of the fabric, results in increasing the effect of impregnation of the fabric in the dye bath, during a same operation, without having the drawbacks of known machines, thanks to the provision of a dyeing system for raising the fabric.

Conformément à l'invention, le deuxième système de teinture, disposé à la descente du tissu est avantageusement un système amovible dont l'alimentation en bain de teinture est, de préférence, faite suivant un débit réduit, notamment dans le cas du traitement de brins simultanément dans la .machine.According to the invention, the second dyeing system, disposed at the descent of the fabric is advantageously a removable system, the supply of dye bath is preferably made at a reduced rate, especially in the case of strand treatment simultaneously in the machine.

La machine conforme à l'invention est dotée de dispo-sitifs de sécurité associés respectivement à la boite 10 en forme de J et aux moyens de déplacement mécaniques du tissu dans le compartiment de stockage 4. Le dispositif de sécurité 13 monté à l'extrémité supérieure de la boite 10 en forme de J a pour rôle de détecter un stockage du tissu à un niveau trop élevé dans la boite 10, qui serait le signe d'une vitesse de déplacement inadaptée dans le compartiment de stockage 4, à la remontée. Le dispositif de sécurité 13 peut être constituée par exemple, par un entonnoir pouvant pivoter autour d'un axe horizontal, en cas de détection d'un stockage trop haut, pour déclencher un contacteur qui arrête le rouleau d'appel 6, 7, 9 ou analogue et, en cas de besoin, peut inverser le sens de fonctionnement de celui-ci jusqu'à ce que le stockage ait atteint, dans la boite 10, un niveau plus bas compatible avec les nécessités du fonctionnement de la machine, l'entonnoir 13 reprenant alors sa position de repos et libérant le contacteur de déclenchement.The machine according to the invention has to say p o sitifs security associated with the box 10 respectively J-shape and the mechanical means for moving the fabric in the storage compartment 4. The safety device 13 mounted at the upper end of the J-shaped box 10 has the role of detecting a storage of the fabric at too high a level. high in the box 10, which would be a sign of an inappropriate speed of movement in the storage compartment 4, on the ascent. The safety device 13 can be constituted for example, by a funnel which can pivot around a horizontal axis, in the event of detection of a storage too high, to trigger a contactor which stops the take-up roller 6, 7, 9 or the like and, if necessary, can reverse the operating direction thereof until the storage has reached, in the box 10, a lower level compatible with the requirements of the operation of the machine, the funnel 13 then resumes its rest position and releasing the trip switch.

Un autre dispositif de sécurité, désigné par la référence 14, est associé au compartiment de stockage ; il peut être constitué, par exemple, par une paroi 14 pivotante, dont le pivotement est provoqué par un avancement trop important du tissu dans le compartiment, au voisinage de la remontée du tissu, dans une mesure propre à risquer de provoquer une interférence avec le tissu en plis 11 sortant de la boite 10 en forme de J (cf. figure 7) ou avec la boite 10 elle-même (cf. figure 4). Le pivotement de la paroi 14 entraîne un réglage de la vitesse de fonctionnement des moyens mécaniques de déplacement du tissu dans le compartiment,4, en particulier un réglage de la vitesse du tapis roulant (figure 7) ou un réglage de la vitesse de rotation du cylindre rotatif ou de la couronne rotative qui constitue le compartiment de stockage.Another security device, designated by the reference 14, is associated with the storage compartment; it may be constituted, for example, by a pivoting wall 14, the pivoting of which is caused by too great advancement of the fabric in the compartment, in the vicinity of the ascent of the fabric, to an extent likely to cause interference with the pleated fabric 11 emerging from the J-shaped box 10 (see Figure 7) or with the box 10 itself (see Figure 4). The pivoting of the wall 14 results in an adjustment of the operating speed of the mechanical means for moving the fabric in the compartment, 4, in particular an adjustment of the speed of the conveyor belt (FIG. 7) or an adjustment of the speed of rotation of the rotary cylinder or rotary crown which constitutes the storage compartment.

A leur sortie de la machine de traitement aqueux, à l'issue du dernier passage dans les systèmes de teinture,de pliage et de stockage, les brins de tissus sont déchargés de la machine à l'aide d'un dispositif de déchargement qui peut être soit fixé à la machine (cf. figure 9), soit indépendant de celle-ot et fixé au sol (cf. figures 10 et 11). Le dispositif de déchargement de tissu conforme à l'invention est monté à la sortie de la machine de traitement aqueux. Bien qu'il soit propre à décharger un nombre quelconque de brins et notamment un seul brin ou plus de deux brins à la fois, il sera décrit ci-après en se référant à un exemple d'application au déchargement de deux brins, un tel exemple étant de nature a illustrer clairement l'efficacité dudit dispositif. En effet, lorsque deux brins (ou plus) ont circulé simultanément en une pluralité de passages, à travers le système de teinture, puis ont été soumis aux opérations de pliage et de stockage, un certain nombre de torsions peuvent s'être produites et empêcher une séparation aisée des deux brins (ou plus) à la fin du traitement, lors du déchargement. Le dispositif de déchargement conforme à la présente invention a peur but de défaire lesdites torsions simultanément aux opérations de déchargement et comporte, à cet effet, les organes suivants: selon un premier mode de réalisation dans lequel le dispositif est monté sur la machine de traitement aqueux, il comporte un entonnoir 15 rotatif à la paroi interne duquel sont solidarisés deux anneaux 16 prévus pour le passage d'un brin 18 dans chacun d'eux après détorsion des brins torsadés 17. Un rouleau moteur 19 solidaire de l'entonnoir 15 est monté au-dessous de chacun des anneaux 16 ; le contact de torsions des brins avec l'entonnoir 15 détermine la mise en rotation de ce dernier jusqu'à l'élimination des torsions et l'arrêt des rouleaux moteurs 19 pendant le même temps. Les deux brins sont reçus soit dans deux chariots distincts 20 de préférence montés sur une plaque rotative 21 dont la rotation est coordonnée à celle de l'entonnoir 15, soit dans un chariot unique fixe, à deux zones de sotckage concentriques. Bien entendu, l'entonnoir rotatif 15 de détorsion ne constitue qu'un exemple non limitatif de réalisation, bien d'autres solutions équivalentes pouvant lui être substituées, notamment deux tiges solidaires et rotatives.On leaving the aqueous treatment machine, after the last pass through the dyeing, folding and storage systems, the strands of fabric are discharged from the machine using an unloading device which can be either fixed to the machine (see figure 9), or independent of it and fixed to the ground (see figures 10 and 11). The fabric unloading device according to the invention is mounted at the outlet of the aqueous treatment machine. Although it is suitable for discharging any number of strands and in particular a single strand or more than two strands at a time, it will be described below with reference to an example of application to the unloading of two strands, such example being of a nature to clearly illustrate the effectiveness of said device. Indeed, when two (or more) strands circulated simultaneously in a plurality of passages, through the dyeing system, then were subjected to the folding and storage operations, a certain number of twists may have occurred and prevent easy separation of the two strands (or more) at the end of the treatment, during unloading. The unloading device according to the present invention is afraid of defeating said twists simultaneously with the unloading operations and comprises, for this purpose, the following members: according to a first embodiment in which the device is mounted on the aqueous treatment machine , it comprises a funnel 15 rotatable to the internal wall of which are secured two rings 16 provided for the passage of a strand 18 in each of them after untwisting the twisted strands 17. A drive roller 19 integral with the funnel 15 is mounted below each of the rings 16; the contact of twists of the strands with the funnel 15 determines the rotation of the latter until the elimination of twists and the stopping of the driving rollers 19 during the same time. The two strands are received either in two separate carriages 20 preferably mounted on a rotary plate 21 whose rotation is coordinated with that of the funnel 15, or in a single fixed carriage, with two concentric sotcking zones. Of course, the rotary twist funnel 15 constitutes only one nonlimiting example of embodiment, many other equivalent solutions which can be substituted for it, in particular two integral and rotary rods.

Selon un autre mode de réalisation des moyens de déchargement, dans lequel le dispositif est indépendant de la machine, lesdits moyens comprennent une plaque rotative 22 qui porte une tige axiale 23 qui supporte à son extrémité supérieure une tige de support 24 des deux anneaux 25 et au-dessous de la tige 24, une deuxième tige 26, parallèle à la première, sur laquelle sont montés deux rouleaux moteurs de déchargement 27, l'ensemble 26-27 pouvant éventuellement être remplacé par un rouleau moteur unique. La torsion des brins 28 parvenant au niveau des anneaux 25 déterminera, par l'in- tcrmédiaire de la tige axiale 23, l'entraînement en rotation de la plaque rotative 22 jusqu'à la disparition des torsions, et le déchargement des brins séparés 29, dans les chariots 30 (figure 10). Suivant une variante de réalisation de ce dispositif, représentée schématiquement à la figure 11, les chariots 30 sont remplacés par un chariot unique 31 monté sur une plaque pivotante 32, à laquelle est solidarisée la tige axiale 23 qui porte les anneaux 25 et les rouleaux moteurs 27.According to another embodiment of the unloading means, in which the device is independent of the machine, said means comprise a rotary plate 22 which carries an axial rod 23 which supports at its upper end a support rod 24 of the two rings 25 and beyond under the rod 24, a second rod 26, parallel to the first, on which are mounted two unloading drive rollers 27, the assembly 26-27 possibly being replaced by a single drive roller. The torsion of the strands 28 arriving at the level of the rings 25 will determine, through the axial rod 23, the rotation drive of the rotary plate 22 until the disappearance of the twists, and the unloading of the separate strands 29 , in the carriages 30 (Figure 10). According to an alternative embodiment of this device, shown schematically in Figure 11, the carriages 30 are replaced by a single carriage 31 mounted on a pivoting plate 32, to which is secured the axial rod 23 which carries the rings 25 and the drive rollers 27.

La motorisation du ou des rouleaux moteurs de déchargement 19 ou 27 est assurée soit par une alimentation électrique rotative, soit par un système à crémaillère.The motorization of the unloading motor roller (s) 19 or 27 is ensured either by a rotary electrical supply or by a rack and pinion system.

Il résulte de la description qui précède que, quels que soient les modes de réalisation et d'application adoptés, l'on obtient des perfectionnements apportés aux machines de traitement aqueux des tissus en pièces qui présentent par rapport aux machines de traitement aqueux visant au même but antérieurement connues, des avantages importants dont certains ont été mentionnés dans ce qui précède et dont d'autres avantages ressortiront de l'utilisation desdites machines de traitement aqueux.It follows from the foregoing description that, whatever the embodiments and application adopted, improvements are made to the machines for aqueous treatment of fabrics in pieces which have, compared to the aqueous treatment machines, aimed at the same previously known purpose, important advantages, some of which have been mentioned in the foregoing and other advantages of which will emerge from the use of said aqueous treatment machines.

.Ainsi que cela ressort de ce qui précède, l'invention ne se limite nullement à ceux de ses modes de réalisation et d'application qui viennent d'être décrits de façon plus explicite ; elle en embrasse au contraire toutes les variantes qui peuvent venir à l'esprit du technicien en la matière, sans s'écarter du cadre, ni de la portée, de la présente invention..As is apparent from the above, the invention is in no way limited to those of its embodiments and of application which have just been described more explicitly; on the contrary, it embraces all the variants which may come to the mind of the technician in the matter, without departing from the framework, or the scope, of the present invention.
