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 drawback 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, so 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 disadvantage, on the one hand, of only allowing the production of a relatively not very clean product 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.
On connaît également, par DE-C-165 596, qui constitue l'état de la technique le plus proche, un dispositif échardonneur comportant trois ensembles qui échardonnent la laine avant de l'envoyer sur le grand tambour. Ce dispositif permet, certes, de bien échardonner, paralléliser, retourner et nettoyer les fibres, mais les vitesses des différents échardonneurs vont en s'accélérant d'un cylindre à l'autre pour arriver à un maximum sur le grand tambour, de sorte que le redressement des impuretés n'est effectué que de manière imparfaite.Also known, from DE-C-165 596, which constitutes the closest state of the art, a skimmer device comprising three assemblies which slag the wool before sending it to the large drum. This device allows, of course, to properly shell, parallelize, turn and clean the fibers, but the speeds of the different scalers are accelerating from one cylinder to another to reach a maximum on the large drum, so that the rectification of impurities is only carried out imperfectly.
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", équipée d'au moins trois cylindres Morel et ne présentant pas de peigneur intermédiaire, caractérisée en ce que les vitesses tangentielles des cylindres alimentaires et du grand tambour sont égales, la réduction de vitesse de la nappe de fibres entre le grand tambour et le cylindre Morel suivant étant relativement faible, de telle sorte que la nappe est freinée et a tendance à accumuler les fibres sur une plus forte épaisseur et, de ce fait, à favoriser un redressement des impuretés permettant leur arrachage par le chasseur.It has, in fact, for a card called "wool", equipped with at least three Morel cylinders and not having an intermediate comber, characterized in that the tangential speeds of the food cylinders and the large drum are equal, the reduction of speed of the ply of fibers between the large drum and the following Morel cylinder being relatively low, so that the ply is braked and tends to accumulate fibers over a greater thickness and, therefore, to favor a straightening impurities allowing their removal by the hunter.
L' invention sera mieux comprise grâce à la description ci-après, qui se rapporte à des modes de réalisation préférés, donnés à titre d'exemples non limitatifs et expliqués avec référence aux dessins schématiques annexés, dans lesquels :
- la figure 1 est une vue en élévation latérale d'une carde conforme à l'invention et,
- les figures 2 et 3 sont des vues analogues à celle de la figure 1 de variantes de réalisation de l'invention.
- FIG. 1 is a side elevation view of a card according to the invention and,
- Figures 2 and 3 are views similar to that of Figure 1 of alternative embodiments of the invention.
Les figures 1 à 3 des dessins annexés représentent une carde dite "laine", équipée d'au moins trois cylindres Morel 1 et dont les vitesses tangentielles des cylindres alimentaires 2 et du grand tambour 3 sont égales, la réduction de vitesse de la nappe de fibres entre le grand tambour 3 et le cylindre Morel 1 suivant étant relativement faible. En outre, cette carde ne présente pas de peigneur intermédiaire.Figures 1 to 3 of the accompanying drawings show a so-called "wool" card, equipped with at least three Morel 1 cylinders and the tangential speeds of the
Comme le montre la figure 1 des dessins annexés, la carde conforme à l'invention peut présenter la disposition suivante : un bac 4 suivi par un grand tambour 3 avec quatre groupes travailleurs 5, ce grand tambour coopérant, par l'intermédiaire d'un cylindre alimentaire 2 avec un premier cylindre Morel 1 comportant un chasseur 6 et suivi, avec interposition d'un autre cylindre alimentaire 2 d'un deuxième cylindre Morel 1.As shown in Figure 1 of the accompanying drawings, the card according to the invention may have the following arrangement: a
A la suite de ce cylindre Morel 1 est prévu un deuxième grand tambour 3 muni de trois groupes travailleurs 5, ce grand tambour 3 étant à nouveau raccordé à un cylindre Morel 1 avec chasseur 6 au moyen d'un autre cylindre alimentaire 2, ce dernier cylindre Morel 1 étant lui-même relié par l'intermédiaire d'un cylindre alimentaire 2 à un dernier grand tambour 3 muni de cinq groupes travailleurs 5.Following this Morel
Dans ce mode de réalisation, la nappe de fibres provenant du bac 4 est amenée par le grand tambour 3 et le cylindre alimentaire 2, à vitesse constante, au premier cylindre Morel 1 dont la vitesse tangentielle est inférieure à celle dudit cylindre alimentaire 2, de sorte que la nappe est freinée et à tendance à accumuler les fibres sur une plus forte épaisseur et, de ce fait, à favoriser un redressement des impuretés permettant leur arrachage par le chasseur 6.In this embodiment, the sheet of fibers coming from the
La nappe peut alors être transmise à vitesse constante au deuxième cylindre Morel 1 en vue d'une deuxième opération d'enlèvement des impuretés dite échardonnage. A la sortie de ce deuxième cylindre Morel, la nappe, reprise par le cylindre alimentaire suivant 2, est accélérée et donc étirée pour être travaillée sur le grand tambour 3 suivant avant de subir une nouvelle décélération en vue du traitement sur le troisième cylindre Morel 1. A la sortie de ce dernier, la nappe est à nouveau accélérée pour subir son étirage définitif.The ply can then be transmitted at constant speed to the second Morel 1 cylinder for a second operation of removal of impurities, known as dehardening. At the exit of this second Morel cylinder, the ply, taken up by the
La figure 2 des dessins annexés représente une variante de réalisation de l'invention, dans laquelle la disposition des cylindres Morel 1 par rapport au grand tambour 3 pourvu de trois groupes travailleurs 5 est inversée.Figure 2 of the accompanying drawings shows an alternative embodiment of the invention, in which the arrangement of Morel
Enfin, la figure 3 représente une autre variante de réalisation de l'invention mettant en oeuvre quatre cylindres Morel 1 disposés en tandem entre le premier grand tambour 3 et le dernier grand tambour 3. Dans ce mode de réalisation, la nappe de fibres peut être travaillée à une vitesse plus élevée du fait que l'échardonnage est réparti en quatre opérations correspondant aux quatre cylindres Morel.Finally, FIG. 3 represents another variant embodiment of the invention using four Morel 1 cylinders arranged in tandem between the first
Selon une variante de réalisation de l'invention, non représentée aux dessins annexés, il est également possible de disposer les cylindres Morel 1 par paire superposée entre deux grands tambours 3. Un tel mode de réalisation permet une limitation importante de l'encombrement de la carde dans le sens longitudinal.According to an alternative embodiment of the invention, not shown in the accompanying drawings, it is also possible to arrange the Morel
Grâce à l'invention, il est possible de réaliser une carde ne nécessitant pas de peigneur intermédiaire et 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 not requiring an intermediate comber and having a significant cleaning power while preserving the fibers from 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 de cylindres Morel au moins égal à trois, 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 number of Morel cylinders at least equal to three, allows a large distribution of the release of thistles and other impurities and therefore limits the reduction of the tangential speed of the fiber web with an accumulation on a lesser thickness, so that the processing speed of a web is increased, which results in a corresponding increase in the efficiency of the machine.
Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés aux dessins annexés. 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 embodiments described and shown in the accompanying drawings. 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.
