The process is characterised in that it involves separating the fleece (1), from the start of its formation on the stripping leather (3), by means of stripping cylinders (2) which are in at least two parts, by means of compressed-air jets directed perpendicularly to the direction of advance of the fleece (1), so as to form various small parallel divisional fleeces (8), progressively winding the selvedges of the small fleeces (8) on themselves, in order to produce small strips, and freeing the latter downstream of the stripping leather (3) in order to bring them into at least one funnel (5) which combines them to form at least one large emerging strip. The invention can be used more particularly in the sector of the textile industry. <IMAGE>

Description

La présente invention concerne le domaine de l'industrie textile, en particulier les peigneuses rectilignes pour fibres longues, notamment la formation du voile à la sortie au niveau du cuir arracheur avant sa transformation en ruban, et a pour objet un procédé de séparation du voile à la sortie des peigneuses rectilignes pour fibres longues.The present invention relates to the field of textile industry, in particular the rectilinear combing machines for long fibers, in particular the formation of the veil at the exit at the level of the tearing leather before its transformation into ribbon, and relates to a process of separation of the veil at the exit of straight combers for long fibers.

L'invention a également pour objet un dispositif pour la mise en oeuvre de ce procédé.The invention also relates to a device for implementing this method.

Sur une peigneuse rectiligne les fibres peignées sont amassées sur le cuir d'arrachage pour former le voile. A la partie aval de ce cuir d'arrachage, le voile ainsi formé est actuellement réuni intégralement dans un entonnoir, afin de former le ruban sortant de la peigneuse.On a rectilinear combing machine the combed fibers are gathered on the tearing leather to form the veil. At the downstream part of this tear-away leather, the veil thus formed is currently completely assembled in a funnel, in order to form the ribbon emerging from the combing machine.

Cependant, ce procédé de réalisation connu, consistant à faire entrer le voile entier sur le cuir d'arrachage et à ne pas le séparer, présente plusieurs inconvénients. D'une part, toutes les soudures se retrouvent, à intervalles réguliers, aux mêmes endroits, de sorte qu'il en résulte des points faibles aux rubans et donc une mauvaise tenue et une cohésion médiocre de ce dernier et, d'autre part, du fait que lesdites soudures se répètent à intervalles réguliers, la régularité, de même que l'aspect et la présentation du ruban, ne donnent pas entière satisfaction en fonction des matières utilisées.However, this known production method, consisting in bringing the entire veil onto the tearing leather and not separating it, has several drawbacks. On the one hand, all the welds are found, at regular intervals, in the same places, so that this results in weak points in the ribbons and therefore poor resistance and poor cohesion of the latter and, on the other hand, the fact that said welds are repeated at regular intervals, the regularity, as well as the appearance and presentation of the tape, are not entirely satisfactory depending on the materials used.

La présente invention a pour but de pallier ces inconvénients en proposant une séparation du voile en au moins deux parties, dès le début de sa formation sur le cuir d'arrachage, et une reprise de ces parties, à l'extrémité aval du cuir d'arrachage, dans un entonnoir.The present invention aims to overcome these drawbacks by proposing a separation of the web in at least two parts, from the start of its training on the tear leather, and a recovery of these parts, at the downstream end of the tear leather, in a funnel.

Elle a, en effet, pour objet un procédé de séparation du voile à la sortie des peigneuses rectilignes pour fibres longues caractérisé en ce qu'il consiste à séparer le voile, dès le début de sa formation sur le cuir d'arrachage, en au moins deux parties, au moyen de jets d'air comprimé dirigés perpendiculairement au sens d'avancement du voile, de manière à former différents petits voiles divisionnaires parallèles, à enrouler progressivement les lisières des petits voiles sur elles-mêmes et à les dégager en aval du cuir d'arrachage pour les amener dans au moins un entonnoir les réunissant en au moins un grand ruban sortant.It has, in fact, for its object a process for separating the veil at the outlet of the straight combers for long fibers, characterized in that it consists in separating the veil, from the start of its formation on the tearing leather, in at at least two parts, by means of compressed air jets directed perpendicular to the direction of advancement of the sail, so as to form different small parallel divisional sails, to gradually wind the edges of the small sails on themselves and to release them downstream tear leather to bring them into at least one funnel uniting them in at least one large outgoing ribbon.

L'invention a également pour objet un dispositif pour la mise en oeuvre de ce procédé, caractérisé en ce qu'il est essentiellement constitué par au moins trois rampes de soufflage disposées au-dessus du cuir d'arrachage entre les cylindres arracheurs et les cylindres d'appel et présentant des buses d'éjection d'air comprimé s'étendant perpendiculairement au sens d'avancement du voile.The invention also relates to a device for the implementation of this method, characterized in that it is essentially constituted by at least three blowing ramps arranged above the tearing leather between the tear-off cylinders and the cylinders call and having compressed air ejection nozzles extending perpendicular to the direction of advance of the web.

L'invention sera mieux comprise, grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques annexés, dans lesquels :

  • la figure 1 est une vue en coupe longitudinale d'un dispositif pour la mise en oeuvre du procédé conforme à l'invention ;
  • la figure 2 est une vue en plan du dispositif suivant la figure 1 ;
  • la figure 3 est une vue en coupe transversale et à plus grande échelle du dispositif suivant les figures 1 et 2, et
  • la figure 4 est une vue partielle en plan de l'extrémité aval du cuir d'arrachage représentant une variante de réalisation de l'entonnoir de formation du ruban.
The invention will be better understood from the following description, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawings, in which:
  • Figure 1 is a longitudinal sectional view of a device for implementing the method according to the invention;
  • Figure 2 is a plan view of the device according to Figure 1;
  • FIG. 3 is a cross-sectional view on a larger scale of the device according to FIGS. 1 and 2, and
  • Figure 4 is a partial plan view of the downstream end of the tearing leather showing an alternative embodiment of the ribbon forming funnel.

Conformément à l'invention, et comme le montrent plus particulièrement, à titre d'exemple, les figures 1 à 3 des dessins annexés, le procédé de séparation du voile de fibres peignées 1 à la sortie des peigneuses rectilignes pour fibres longues consiste à séparer le voile 1, dès le début de sa formation sur le cuir d'arrachage 3, au moyen de cylindres arracheurs 2, en au moins deux parties, au moyen de jets d'air comprimé dirigés perpendiculairement au sens d'avancement du voile 1, de manière à former différents petits voiles divisionnaires parallèles 8, à enrouler progressivement les lisières des petits voiles 8 sur elles-mêmes, afin de réaliser de petits rubans, et à dégager ces derniers en aval du cuir d'arrachage 3 pour les amener dans au moins un entonnoir 5 les réunissant en au moins un grand ruban sortant.In accordance with the invention, and as shown more particularly, by way of example, FIGS. 1 to 3 of the accompanying drawings, the process for separating the web of combed fibers 1 at the outlet of the straight combers for long fibers consists in separating the web 1, from the start of its formation on the tear leather 3, by means of tear cylinders 2, in at least two parts, by means of compressed air jets directed perpendicularly to the direction of travel of the web 1, so as to form different small parallel divisional sails 8, to progressively wind the selvedges of the small sails 8 on themselves, in order to produce small ribbons, and to release the latter downstream of the tearing leather 3 to bring them into the at least one funnel 5 joining them in at least one large outgoing ribbon.

Le dispositif pour la mise en oeuvre de ce procédé est caractérisé en ce qu'il est essentiellement constitué par au moins trois rampes 7 de soufflage disposées au-dessus du cuir d'arrachage 3 entre les cylindres arracheurs 2 et les cylindres d'appel 4 et présentant des buses d'éjection d'air comprimé s'étendant perpendiculairement au sens d'avancement du voile 1.The device for implementing this method is characterized in that it is essentially constituted by at least three blowing ramps 7 arranged above the tear-off leather 3 between the tear-off cylinders 2 and the call cylinders 4 and having compressed air ejection nozzles extending perpendicular to the direction of travel of the web 1.

Les rampes 7 avec leurs buses d'éjection d'air comprimé sont avantageusement intégrées dans la surface de recouvrement 6 maintenant le voile 1 sur le cuir d'arrachage 3, entre les cylindres 2 et 4, une rampe 7 étant prévue le long de chaque bord du cuir d'arrachage 3. Ces rampes 7 sont disposées, de préférence, parallèlement au sens d'avancement du voile 1 ou légèrement en biais en épousant la trajectoire des lisières des différents petits voiles divisionnaires 8. Le nombre de rampes 7 est fonction du nombre de voiles divisionnaires 8 à réaliser et leurs buses d'éjection d'air comprimé peuvent présenter une section circulaire, oblongue, carrée, rectangulaire ou autre.The ramps 7 with their compressed air ejection nozzles are advantageously integrated into the covering surface 6 holding the web 1 on the tear leather 3, between the cylinders 2 and 4, a ramp 7 being provided along each edge of the tearing leather 3. These ramps 7 are preferably arranged parallel to the direction of advancement of the web 1 or slightly at an angle following the trajectory of the edges of the various small divisional sails 8. The number of ramps 7 is a function of the number of divisional sails 8 to be produced and their compressed air ejection nozzles may have a circular, oblong, square, rectangular or other section.

De manière connue en soi, l'alimentation des rampes 7 peut être réalisée à partir d'un réseau d'air comprimé avec interposition d'un manodétendeur ou par toute autre source d'air comprimé.In a manner known per se, the supply of the ramps 7 can be carried out from a compressed air network with the interposition of a pressure regulator or by any other source of compressed air.

A la sortie du peigne circulaire et du peigne fixe, le voile de fibres peignées 1 est pris par les cylindres arracheurs 2, qui le déposent sur le cuir d'arrachage 3. Ce dernier fait avancer le voile 1 jusqu'au cylindre d'appel 4 qui l'amène dans l'entonnoir 5. Lors du passage sur le cuir d'arrachage 3, le voile 1 est séparé, entre la surface de recouvrement 6 et le cuir d'arrachage 3, par les jets d'air provenant des buses des rampes de soufflage 7, en plusieurs petits voiles divisionnaires 8 qui, lors de l'avance du cuir 3, deviennent des petits rubans sous l'effet du soufflage sur leurs lisières. Ces petits rubans sont regroupés ensuite, au moyen des cylindres d'appel 4 dans l'entonnoir 5 qui les réunit en un grand ruban sortant.At the outlet of the circular comb and the fixed comb, the veil of combed fibers 1 is taken up by the tearing cylinders 2, which deposit it on the tearing leather 3. The latter advances the veil 1 to the call cylinder 4 which brings it into the funnel 5. When passing over the tearing leather 3, the web 1 is separated, between the covering surface 6 and the tearing leather 3, by the air jets coming from the nozzles of the blowing ramps 7, in several small divisional webs 8 which, during the advancement of the leather 3, become small ribbons under the effect of the blowing on their selvedges. These small ribbons are then grouped together, by means of the call cylinders 4 in the funnel 5 which joins them in a large outgoing ribbon.

Sous l'effet du soufflage sur les lisières des petits voiles divisionnaires 8 et sur les fibres en général, ces dernières sont bien imbriquées les unes dans les autres, ce qui confère au ruban obtenu une meilleure tenue et une meilleure cohésion le rendant moins fragile et moins sujet aux irrégularités, de sorte que les opérations suivantes sont facilitées et que sa qualité est améliorée.Under the effect of blowing on the selvedges of the small divisional webs 8 and on the fibers in general, the latter are well nested one inside the other, which gives the ribbon obtained better hold and better cohesion making it less fragile and less prone to irregularities, so that the following operations are facilitated and its quality is improved.

Du fait de la division du voile 1, les différents petits voiles 8 peuvent être décalés, de sorte que les soudures ne soient plus à intervalles réguliers, mais soient dispersées dans le ruban, étant décalées les unes par rapport aux autres. Ainsi, la régularité, l'aspect et la présentation du ruban sont améliorés, notamment dans le cas d'utilisation de certaines matières, ce qui est très bénéfique pour la qualité du produit sortant. En outre, la multiplication des divisions du voile 1 par l'augmentation des rampes de soufflage 2 permet une meilleure imbrication et un meilleur entremêlage des fibres, de sorte que la tenue et la cohésion du rubant sortant sont améliorées.Due to the division of the web 1, the different small webs 8 can be offset, so that the welds are no longer at regular intervals, but are dispersed in the tape, being offset with respect to each other. So the regularity, appearance and the presentation of the ribbon are improved, in particular in the case of the use of certain materials, which is very beneficial for the quality of the outgoing product. In addition, the multiplication of the divisions of the web 1 by increasing the blowing ramps 2 allows better nesting and better intermingling of the fibers, so that the strength and cohesion of the outgoing tape are improved.

Selon une variante de réalisation de l'invention, non représentée aux dessins annexés, les différents petits voiles divisionnaires 8 peuvent être réunis en plusieurs entonnoirs.According to an alternative embodiment of the invention, not shown in the accompanying drawings, the various small divisional webs 8 can be joined in several funnels.

La figure 4 des dessins annexés, représente une autre variante de réalisation de l'invention, dans laquelle les petits voiles divisionnaires 8, enroulés en rubans individuels, sont amenés dans au moins un entonnoir 9 excentré par rapport à l'axe du cuir d'arrachage 3. Ainsi, lors de la réunion des rubans individuels les soudures de chaque ruban sont décalées par rapport à celles des autres rubans, chaque ruban suivant une trajectoire différente lors de son passage dans la sortie excentrée, de sorte que la tenue, la cohésion et surtout la régularité du ruban sortant sont améliorées.Figure 4 of the accompanying drawings shows another alternative embodiment of the invention, in which the small divisional sails 8, wound in individual ribbons, are brought into at least one funnel 9 offset from the axis of the leather of tearing off 3. Thus, during the meeting of the individual ribbons the welds of each ribbon are offset with respect to those of the other ribbons, each ribbon following a different trajectory as it passes through the eccentric outlet, so that the holding, the cohesion and especially the regularity of the outgoing tape are improved.

De manière connue, la soudure entre les fibres des petits voiles divisionnaires 8 s'effectue par une avance du cuir d'arrachage 3 suivant la flèche 10 suivie d'un recul de moindre amplitude suivant la flèche 11.In known manner, the welding between the fibers of the small divisional webs 8 is carried out by advancing the tearing leather 3 according to arrow 10 followed by a retraction of lesser amplitude following arrow 11.

Grâce à l'invention, il est possible de réaliser une formation de rubans à la sortie de peigneuses rectilignes avec séparation préalable du voile, au début de sa formation sur le cuir d'arrachage, en plusieurs petits voiles divisionnaires, et reprise de ces derniers à la partie aval du cuir d'arrachage, sous forme de petits rubans, dans un ou plusieurs entonnoirs.Thanks to the invention, it is possible to form ribbons at the exit of rectilinear combing machines with prior separation of the web, at the start of its training on the tearing leather, in several small divisional webs, and recovery of the latter. at the downstream part of the tearing leather, in the form of small ribbons, in one or more funnels.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté 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 embodiment 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.
