Description

La présente invention concerne le domaine de l'industrie textile, en particulier les cardes dites "laine" travaillant les laines et les fibres longues et a pour objet une telle carde.The present invention relates to the field of textile industry, in particular the so-called "wool" cards working wool and long fibers and has for its object such a card.

Actuellement, les cardes existantes de ce type sont généralement des cardes doubles avec un peigne intermédiaire présentant une réduction de vitesse importante et un pouvoir d'épuration élévé.Currently, existing cards of this type are generally double cards with an intermediate comb having a significant reduction in speed and a high cleaning power.

Une telle configuration présente l'inconvénient de provoquer des raccourcissements des fibres, ce qui est très préjudiciable pour le produit fini, du fait que, d'une manière générale, pour l'obtention d'un fil d'une qualité optimale il faut chercher à obtenir et à conserver des fibres d'une longueur maximale.Such a configuration has the disadvantage of causing shortening of the fibers, which is very detrimental for the finished product, since, in general, to obtain a thread of optimum quality it is necessary to seek to obtain and maintain fibers of maximum length.

Dans ces cardes existantes, il est généralement fait appel à deux cylindres Morel montés en tandem ou d'autre manière.In these existing cards, it is generally used two Morel cylinders mounted in tandem or otherwise.

Pour l'obtention d'un effet de peignage, la vitesse de la nappe de fibres à traiter est réduite avant chaque cylindre Morel, entre le cylindre alimentaire et le grand tambour, de telle manière que l'orientation des impuretés contenues dans la nappe de fibres soit modifiée afin que le chasseur du cylindre Morel correspondant les élimine.To obtain a combing effect, the speed of the layer of fibers to be treated is reduced before each Morel cylinder, between the food cylinder and the large drum, in such a way that the orientation of the impurities contained in the layer of fibers are modified so that the corresponding Morel cylinder hunter eliminates them.

Toutefois, l'utilisation de ce nombre réduit de cylindres Morel présente l'inconvénient, d'une part, de ne permettre l'obtention que d'un produit relativement peu propre et, d'autre part, du fait de ce nombre réduit de cylindres, la réduction de vitesse nécessaire au niveau de chaque cylindre Morel est très importante et entraîne une casse des fibres, ce qui nuit considérablement à la qualité du produit obtenu.However, the use of this reduced number of Morel cylinders has the drawback, on the one hand, of only allowing a relatively unclean product to be obtained and, on the other hand, due to this reduced number of cylinders, the reduction in speed required at each Morel cylinder is very significant and causes fiber breakage, which considerably affects the quality of the product obtained.

Une réduction de vitesse importante au niveau de chaque cylindre Morel est plus particulièrement nécessaire du fait qu'un maximum d'impuretés, telles que des chardons, des pailles ou d'autres fibres végétales, doit être arraché de la nappe accumulée sur chaque cylindre Morel lors de son passage sous le chasseur correspondant.A significant speed reduction at the level of each Morel cylinder is more particularly necessary the fact that a maximum of impurities, such as thistles, straws or other vegetable fibers, must be torn from the tablecloth accumulated on each Morel cylinder during its passage under the corresponding hunter.

En outre, du fait de la réduction importante de vitesse au niveau de chaque cylindre Morel, la nappe de fibres est dégagée à une vitesse relativement faible, ce qui entraîne un rendement relativement faible.In addition, due to the significant reduction in speed at each Morel cylinder, the sheet of fibers is released at a relatively low speed, which results in a relatively low yield.

De plus, chaque cylindre Morel n'étant équipé que d'un seul chasseur, l'échardonnage est limité et, en présence d'une matière à l'alimentation très chargée d'impuretés, le produit sortant présente une propreté imparfaite.In addition, each Morel cylinder being equipped with only one hunter, the shredding is limited and, in the presence of a material in the feed highly charged with impurities, the outgoing product has an imperfect cleanliness.

Enfin, l'implantation de cylindres Morel en tandem, destinés à permettre l'obtention d'un produit final de meilleure qualité, entraîne un encombrement beaucoup plus important de la carde et une diminution conséquente de la vitesse de travail de cette dernière, du fait de l'augmentation du nombre de transferts entre les cylindres, d'où il résulte un rendement relativement faible.Finally, the installation of Morel cylinders in tandem, intended to allow obtaining a final product of better quality, leads to a much larger size of the card and a consequent reduction in the working speed of the latter, due to the fact the increase in the number of transfers between the cylinders, which results in a relatively low efficiency.

La présente invention a pour but de pallier ces inconvénients.The present invention aims to overcome these drawbacks.

Elle a, en effet, pour objet une carde dite "laine", comportant au moins deux cylindres Morel, caractérisée en ce que chaque cylindre Morel est pourvu d'au moins deux chasseurs, la réduction de vitesse de la nappe de fibres entre le grand tambour et le cylindre Morel suivant étant relativement faible.It has, in effect, for a card called "wool", comprising at least two Morel cylinders, characterized in that each Morel cylinder is provided with at least two hunters, reducing the speed of the web of fibers between the large drum and the following Morel cylinder being relatively small.

L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemples non limitatifs et expliqué avec référence au dessin schématique annexé, dont la figure unique est une vue en élévation latérale d'une carde conforme à l'invention.The invention will be better understood thanks to the description below, which relates to a preferred embodiment, given by way of nonlimiting examples and explained with reference to the appended schematic drawing, the single figure of which is a view in elevation. side of a card according to the invention.

Le dessin annexé représente une partie de carde dite laine, dont un cylindre Morel 1 est monté, avec interposition de cylindres communicateurs 2, entre deux grands tambours 3. Dans une telle carde, la nappe de fibres amenée par le grand tambour 3 en amont est déviée au moyen du premier cylindre communicateur 2 sur le cylindre Morel 1 en vue de son traitement d'échardonnage, un autre traitement d'échardonnage étant effectué sur au moins un deuxième cylindre Morel, non représenté.The attached drawing represents a part of a so-called woolen card, of which a Morel 1 cylinder is mounted, with interposition of communicating cylinders 2, between two large drums 3. In such a card, the sheet of fibers brought by the large drum 3 upstream is deflected by means of the first communicating cylinder 2 on the Morel cylinder 1 for its treatment of skinning, another skinning treatment being carried out on at least one second Morel cylinder, not shown.

Conformément à l'invention, chaque cylindre Morel 1 est pourvu d'au moins deux chasseurs 4 et la réduction de vitesse de la nappe de fibres entre le grand tambour 3 et le cylindre Morel 1 suivant est relativement faible. Ce mode de réalisation permet au moins de doubler les opérations d'épuration sur chaque cylindre Morel 1 et ainsi d'augmenter considérablement l'évacuation des impuretés végétales.According to the invention, each Morel cylinder 1 is provided with at least two hunters 4 and the reduction in speed of the sheet of fibers between the large drum 3 and the following Morel cylinder 1 is relatively small. This embodiment makes it possible at least to double the purification operations on each Morel 1 cylinder and thus to considerably increase the evacuation of plant impurities.

Selon une autre caractéristique de l'invention, le premier chasseur 4 de chaque cylindre Morel 1, vu dans le sens de progression de la nappe de fibres à traiter, présente avantageusement un nombre de lames restreint, tourne à une vitesse relativement faible et évacue les grosses impuretés par un effet d'arrachage, le ou les chasseurs 4 suivants présentant un nombre de lames supérieur, tournant à une vitesse supérieure et éliminant les impuretés plus fines, essentiellement par effet d'aspiration, le réglage des premiers chasseurs 4 et des autres chasseurs 4 étant effectué indépendament à des distances différentes des cylindres Morel 1 correspondants. Ainsi, il est possible d'échardonner toutes les matières végétales de finesse différente, de manière optimale.According to another characteristic of the invention, the first hunter 4 of each Morel cylinder 1, seen in the direction of progression of the sheet of fibers to be treated, advantageously has a limited number of blades, rotates at a relatively low speed and evacuates the large impurities by a lifting effect, the following hunter (s) 4 having a higher number of blades, rotating at a higher speed and eliminating finer impurities, essentially by suction effect, the adjustment of the first hunters 4 and of the others hunters 4 being carried out independently at different distances from the corresponding Morel 1 cylinders. Thus, it is possible to split all vegetable materials of different fineness, optimally.

Conformément à une autre caractéristique de l'invention, les cylindres Morel 1, équipés de plusieurs chasseurs 4, sont disposés à différents endroits de la carde et sont, soit accouplés entre eux, soit entraînés séparément.In accordance with another characteristic of the invention, the Morel 1 cylinders, equipped with several hunters 4, are arranged at different locations on the card and are either coupled to one another, or driven separately.

Le regroupement de plusieurs chasseurs 4 sur un même cylindre Morel 1 permet l'obtention d'un ensemble beaucoup moins encombrant qu'une disposition de deux cylindres Morel en tandem. En outre., il est possible de réaliser une construction de cardes plus compacte avec plus grande efficacité des chasseurs 4.The grouping of several hunters 4 on the same Morel 1 cylinder makes it possible to obtain an assembly much less bulky than an arrangement of two Morel cylinders in tandem. In addition, it is possible to produce a more compact card construction with greater efficiency of the hunters 4.

L'augmentation des chasseurs 4 dans une carde permet la réduction du nombre de points de transfert et, ainsi, une augmentation de la vitesse périphérique des cylindre Morel 1 et donc une augmentation des plages de vitesse de ces derniers et des chasseurs 4.The increase in hunters 4 in a card allows the number of transfer points to be reduced and, therefore, an increase in the peripheral speed of the Morel 1 cylinders and therefore an increase in the speed ranges of the latter and of the hunters 4.

Grâce à l'invention, il est possible de réaliser une carde présentant un pouvoir d'épuration important tout en préservant les fibres de la casse, ces dernières étant, de ce fait, de meilleure qualité. Il en résulte que le produit obtenu est un produit mieux raffiné.Thanks to the invention, it is possible to produce a card having a significant cleaning power while preserving the fibers of the breakage, the latter being, therefore, of better quality. As a result, the product obtained is a better refined product.

En outre, la prévision d'un nombre important de chasseurs 4 permet une importante répartition du dégagement des chardons et autres impuretés et donc de limiter la réduction de la vitesse tangentielle de la nappe de fibres avec une accumulation sur une moindre épaisseur, de sorte que la vitesse de traitement d'une nappe est augmentée, ce qui entraîne une augmentation correspondante du rendement de la machine.In addition, the provision of a large number of hunters 4 allows a large distribution of the release of thistles and other impurities and therefore to limit the reduction in the tangential speed of the sheet of fibers with an accumulation on a lesser thickness, so that the processing speed of a sheet is increased, which results in a corresponding increase in the efficiency of the machine.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté au dessin annexé. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments, ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawing. Modifications remain possible, in particular from the point of view of the constitution of the various elements, or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
