Abstract

The invention concerns a rectilinear combing method and a combing machine therefor. Said method is characterised in that it consists essentially in combing the fibre heads with a circular comb (7), equipped with needles or teeth (8) distributed over at least 60 % of its periphery, said circular comb (7) performing a fraction number or a whole number of rotations (N) per machine cycle. The invention is more particularly applicable in the textile industry, in particular to rectilinear combing machines.

Description

La présente invention concerne le domaine de l'industrie textile, en particulier les peigneuses rectilignes et a pour objet un procédé de peignage et une peigneuse pour la mise en oeuvre de ce procédé.The present invention relates to the field of the textile industry, in particular rectilinear combers and relates to a method of combing and a combing machine for the implementation of this process.

Le cycle de peignage des peigneuses rectilignes modernes, qui sont dérivées de modèles datant du milieu du 19ème siècle, est bien connu et peut être décomposé en deux phases, dont la première est dite de peignage des têtes de fibres et la seconde de peignage des queues de fibres. La phase de peignage des têtes de fibres intervient lorsque la pince est fermée, alors que la phase de peignage des queues de fibres intervient au moment de l'arrachage, lorsque la pince est ouverte.Combing cycle modern rectilinear combing machines, which are derived from models from the mid-19th century, is well known and can be divided into two phases, the first of which is called combing the fiber heads and the second combing fiber tails. The combing phase of the fiber heads occurs when the pliers are closed, while the combing phase of the fiber tails takes place when the pliers are pulled out, when the pliers are open.

La phase de peignage des têtes de fibres est réalisée par un segment d'aiguilles ou de dents disposé sur une partie de la périphérie d'un cylindre rotatif, couramment appelé peigne circulaire, alors que la phase de peignage des queues de fibres est réalisée par un peigne couramment appelé peigne fixe ou rectiligne.The combing phase of the fiber heads is carried out by a segment of needles or teeth arranged on a part of the periphery of a rotary cylinder, commonly called a circular comb, while the phase of combing the tails of fibers is carried out by a comb commonly called fixed or straight comb.

Le peigne circulaire, dont l'axe de rotation est fixe par rapport au bâti de la machine, effectue un tour complet par cycle de machine. Ce peigne circulaire est un cylindre, dont une partie de la périphérie est pourvue d'un segment garni d'aiguilles ou de dents à densité croissante par rapport au sens de rotation du cylindre et qui sera utilisé, afin de nettoyer les têtes de fibres dépassant de la pince lors de la phase de peignage des têtes. Dans certains cas, la vitesse du peigne circulaire est successivement accélérée puis ralentie, pendant un cycle complet de la machine.The circular comb, whose axis of rotation is fixed relative to at the machine frame, make one complete revolution per machine cycle. This circular comb is a cylinder, part of whose periphery is provided with a segment furnished with needles or teeth with increasing density by relative to the direction of rotation of the cylinder and which will be used, in order to clean the fiber heads protruding from the clamp during the combing phase of the heads. In some cases, the speed of the circular comb is successively accelerated then slowed down, during a complete cycle of the machine.

L'autre partie de la périphérie du cylindre n'est pas pourvue d'aiguilles mais est lisse et évidée parce que la présence d'aiguilles sur cette partie du cylindre n'est pas nécessaire au moment de l'arrachage et du fait qu'il faut ménager de la place pour les éléments mécaniques en mouvement lors de l'opération d'arrachage. En effet, comme il ressort de différentes publications, d'une part, les aiguilles du peigne circulaire ne peuvent être montées que sur une partie seulement de la surface du cylindre qui les porte (FR-A-2 114 192) et, d'autre part, il y a risque de collision entre le peigne circulaire et la mâchoire inférieure de pince, qui fait partie des éléments mécaniques en mouvement, lors de l'opération d'arrachage (EP-A-0 936 292). The other part of the periphery of the cylinder is not provided needles but is smooth and hollowed out because the presence of needles on this part of the cylinder is not necessary at the time of lifting and because space must be made for moving mechanical elements during the lifting operation. Indeed, as is apparent from different publications, on the one hand, the circular comb needles cannot be mounted on only part of the surface of the cylinder carrying them (FR-A-2 114 192) and, on the other hand, there is a risk of collision between the comb circular and the lower clamp jaw, which is part of the elements mechanical moving, during the lifting operation (EP-A-0 936 292).

Par ailleurs, d'après EP-A-0 735 168, on sait qu'une collision entre le peigne circulaire , la pince , les cylindres arracheurs et le capteur pneumatique doit être évitée.Furthermore, according to EP-A-0 735 168, it is known that a collision between the circular comb, the pliers, the lifting cylinders and the sensor pneumatic should be avoided.

Le segment est généralement garni d'aiguilles à densité croissante (FR-A-1 209 191), de manière à assurer un peignage progressif des têtes de fibres. Ainsi, les premières barrettes d'aiguilles sont garnies d'aiguilles de fortes dimensions et largement espacées alors que les dernières barrettes d'aiguille sont garnies d'aiguilles plus fines et serrées.The segment is usually lined with density needles increasing (FR-A-1 209 191), so as to ensure progressive combing fiber heads. Thus, the first bars of needles are filled large and widely spaced needles while the last needle bars are trimmed with finer and tight needles.

Actuellement, le segment d'aiguilles du peigne circulaire est nettoyé par une brosse cylindrique (FR-A-2 651 512) qui est elle-même débourrée par un cylindre doffer, lequel est déchargé à son tour par un peigne battant. A cet effet, la vitesse de rotation de la brosse cylindrique, dont le sens de rotation est inverse de celui du peigne circulaire, est supérieure à celle du peigne circulaire. Ainsi, à chaque cycle de peignage d'une peigneuse rectiligne moderne, le peigne circulaire effectue une rotation d'un tour complet et le segment garni d'aiguilles, en passant en face de la brosse cylindrique, est nettoyé une seule fois par cycle.Currently, the circular comb needle segment is cleaned by a cylindrical brush (FR-A-2 651 512) which is itself disengaged by a doffer cylinder, which in turn is discharged by a beating comb. For this purpose, the speed of rotation of the cylindrical brush, whose direction of rotation is opposite to that of the circular comb, is greater than that of the circular comb. So, at each combing cycle of a modern rectilinear combing machine, the circular comb performs a complete rotation and the segment with needles, passing in front of the cylindrical brush, is cleaned only once per cycle.

On sait que la qualité du ruban peigné, notamment sa propreté, dépend de l'efficacité du peignage des têtes et des queues de fibres, laquelle n'est pas optimale si le peigne circulaire n'est pas correctement nettoyé par la brosse cylindrique. Or il arrive fréquemment qu'un nettoyage satisfaisant des aiguilles ou des dents du segment garni ne puisse pas être obtenu.We know that the quality of the combed tape, especially its cleanliness, depends on the effectiveness of combing the heads and tails of fibers, which is not optimal if the circular comb is not properly cleaned by the cylindrical brush. However it often happens that a satisfactory cleaning needles or teeth of the trimmed segment cannot be obtained.

En effet, du fait de la progressivité de la densité des aiguilles ou des dents du segment du peigne circulaire, les impuretés végétales et les défauts tels que les boutons et les fibres trop courtes, que le segment est chargé de retirer des rubans à peigner, se coincent très facilement entre les aiguilles ou les dents des barrettes, dont les aiguilles ou les dents sont les plus fines et les plus rapprochées, et la brosse cylindrique ne parvient pas à les retirer du peigne circulaire.Indeed, due to the progressiveness of the density of the needles or teeth of the circular comb segment, plant impurities and defects such as buttons and fibers too short, that the segment is responsible for removing combing ribbons, very easily get caught between the needles or bar teeth, of which the needles or teeth are thinner and closer together, and the cylindrical brush fails to remove them from the circular comb.

Il est donc périodiquement nécessaire de nettoyer manuellement le segment du peigne circulaire en arrêtant la machine. Cette opération nécessite parfois de retirer le peigne circulaire. A défaut, la qualité du ruban peigné se dégraderait progressivement.It is therefore periodically necessary to clean manually the circular comb segment by stopping the machine. This operation sometimes requires removing the circular comb. Otherwise, the quality of the combed tape would gradually deteriorate.

Pour remédier à cet inconvénient il avait été proposé d'utiliser des brosses à poils très durs, voire même métalliques (DE-A-328 146), qui ne donnaient, cependant, pas satisfaction car elles entraínaient une usure rapide des aiguilles ou des dents du segment garni. Il a également été proposé, par EP-A-0 735 168, d'effectuer au moins deux tours de peigne circulaire par cycle de machine, de façon à nettoyer le segment garni au moins deux fois par cycle.To remedy this drawback, it had been proposed to use brushes with very hard bristles, or even metallic bristles (DE-A-328 146), which were not satisfactory, however, as they led to wear rapid needles or teeth of the trimmed segment. He was also proposed by EP-A-0 735 168 to make at least two comb turns circular per machine cycle, so as to clean the segment filled with minus twice per cycle.

Cependant, du fait de la progressivité de la densité du garnissage des segments d'aiguilles, et malgré plusieurs brossages du segment garni, les impuretés s'accumulent entre les aiguilles ou les dents les plus fines et les plus serrées. Il en résulte une dégradation progressive de la propreté des rubans peignés.However, due to the progressive density of the filling of the needle segments, and despite several brushing of the trimmed segment, impurities accumulate between the needles or the teeth thinner and tighter. This results in a gradual deterioration of the clean combed ribbons.

La présente invention a pour but de pallier ces inconvénients en proposant un nouveau procédé de peignage rectiligne et une nouvelle peigneuse rectiligne mettant en oeuvre ce procédé, permettant une amélioration des qualités de peignage, ainsi que du nettoyage du peigneThe object of the present invention is to overcome these drawbacks by proposing a new rectilinear combing process and a new rectilinear combing machine implementing this method, allowing a improvement of combing qualities, as well as comb cleaning

A cet effet, le procédé de peignage rectiligne est caractérisé en ce qu'il consiste essentiellement à effectuer un peignage des têtes de fibres pendant environ un tour complet de rotation d'un peigne circulaire, garni d'aiguilles ou de dents sur toute sa périphérie, lors d'un cycle de machine, ledit peigne circulaire effectuant plus d'un tour complet de rotation par cycle de machine;To this end, the rectilinear combing process is characterized by what it basically involves combing the fiber heads for about one full rotation of a circular comb, trimmed needles or teeth around its entire periphery, during a machine cycle, said circular comb carrying out more than one complete revolution of rotation by machine cycle;

L'invention a également pour objet une nouvelle peigneuse rectiligne mettant en oeuvre ce procédé, comprenant un dispositif d'alimentation, un dispositif d'arrachage, un dispositif de nettoyage des têtes de fibres comportant un peigne circulaire et un dispositif de nettoyage des queues de fibres, caractérisée en ce que le peigne circulaire est un cylindre garni sur toute sa périphérie d'aiguilles ou de dents, de caractéristiques identiques ou différentes, mais disposées selon une séquence répétitive, cylindre dont la vitesse de rotation est continue et réglable, ce peigne effectuant environ un tour complet de rotation pendant la phase de peignage des têtes de fibres et plus d'un tour complet par cycle de machine.The invention also relates to a new combing machine straight line implementing this method, comprising a device feeder, lifting device, head cleaning device of fibers comprising a circular comb and a device for cleaning the fiber tails, characterized in that the circular comb is a cylinder trimmed over its entire periphery with needles or teeth, identical or different, but arranged in a repeating sequence, cylinder whose speed of rotation is continuous and adjustable, this comb performing approximately one full turn of rotation during the combing phase fiber heads and more than one complete revolution per machine cycle.

    • La figure 1 des dessins annexés représente une peigneuse rectiligne comportant un peigne alimentaire 1 associé à une grille alimentaire 2, une pince 3 formée par une mâchoire supérieure 4 coopérant avec une mâchoire inférieure 5, une tôle entre pince 6, un peigne circulaire 7, garni d'aiguilles ou de dents 8, dont la vitesse de rotation est continue et qui est monté sur un arbre de support 9, dont la position est fixe par rapport au bâti 10 de la machine, une brosse cylindrique 11 garnie de poils, un doffer 12 garni de pointes métalliques, un peigne battant 13, un chariot 14 support de cylindres arracheurs 15 et 16, une biellette 17, un équipage mobile 18, un manchon d'arrachage 19, un cylindre de tension 20 et un peigne fixe 21 solidaire d'un levier articulé 22.Figure 1 of the accompanying drawings shows a combing machine rectilinear comprising a food comb 1 associated with a grid food 2, a clamp 3 formed by an upper jaw 4 cooperating with a lower jaw 5, a sheet between clamp 6, a circular comb 7, furnished with needles or teeth 8, the speed of rotation of which is continuous and which is mounted on a support shaft 9, the position of which is fixed relative to to the frame 10 of the machine, a cylindrical brush 11 furnished with bristles, a doffer 12 with metal spikes, a beating comb 13, a carriage 14 support for lifting cylinders 15 and 16, a connecting rod 17, a crew mobile 18, a tear-off sleeve 19, a tension cylinder 20 and a fixed comb 21 secured to an articulated lever 22.

    Conformément à l'invention, cette peigneuse rectiligne met en oeuvre un procédé de peignage rectiligne qui consiste essentiellement à effectuer un peignage des têtes de fibres pendant environ un tour complet de rotation du peigne circulaire 7, garni d'aiguilles ou de dents 8 sur toute sa périphérie, lors d'un cycle de machine, ledit peigne circulaire 7 effectuant plus d'un tour complet de rotation N par cycle de machine.According to the invention, this straight combing machine works a straight combing process which essentially consists of comb the fiber heads for about a full turn of rotation of the circular comb 7, furnished with needles or teeth 8 over its entire periphery, during a machine cycle, said circular comb 7 performing more than one full revolution of rotation N per machine cycle.

    Selon une caractéristique de l'invention, l'arc actif du peigne 7, correspondant à la longueur de la garniture d'aiguilles ou de dents 8 utilisée lors de la phase de peignage des têtes de fibres, est déphasé d'un cycle machine à l'autre.According to a characteristic of the invention, the active arc of the comb 7, corresponding to the length of the trim of needles or teeth 8 used during the combing phase of the fiber heads, is out of phase with one cycle machine to another.

    Conformément à une autre caractéristique de l'invention, le peignage des têtes de fibres par le peigne circulaire 7 est avantageusement effectué pendant une rotation de ce dernier comprise entre 0,7 et 1,5 tour.In accordance with another characteristic of the invention, the combing the fiber heads by the circular comb 7 is advantageously performed during a rotation of the latter of between 0.7 and 1.5 turns.

    Selon une variante de réalisation de l'invention, le peignage des têtes de fibres peut préférentiellement être effectué pendant moins d'un tour complet de rotation du peigne circulaire 7, ce dernier effectuant plus d'un tour complet de rotation par cycle de machine.According to an alternative embodiment of the invention, the combing of fiber heads can preferably be carried out for less than one turn complete rotation of the circular comb 7, the latter performing more than one complete rotation per machine cycle.

    Il est également possible, conformément à une autre variante de réalisation de l'invention, d'effectuer le peignage des têtes de fibres pendant plus d'un tour complet de rotation du peigne circulaire 7, ledit peigne circulaire 7 effectuant plus d'un tour complet de rotation par cycle de machine.It is also possible, in accordance with another variant of embodiment of the invention, to comb the heads of fibers during more than one full revolution of rotation of the circular comb 7, said comb circular 7 performing more than one complete rotation per cycle of machine.

    A cet effet, le peigne circulaire 7 est un cylindre garni sur toute sa périphérie d'aiguilles ou de dents 8, de caractéristiques identiques ou différentes, mais disposées selon une séquence répétitive, cylindre dont la vitesse de rotation est continue et réglable, ce peigne 7 effectuant environ un tour complet de rotation pendant la phase de peignage des têtes de fibres 23 (figure 2) et plus d'un tour complet par cycle de machine.For this purpose, the circular comb 7 is a cylinder packed on all its periphery of needles or teeth 8, with identical characteristics or different, but arranged in a repetitive sequence, cylinder whose rotation speed is continuous and adjustable, this comb 7 performing approximately a full rotation during the fiber head combing phase 23 (Figure 2) and more than one complete revolution per machine cycle.

    La figure 1 des dessins annexés représente la peigneuse rectiligne conforme à l'invention, en phase d'arrachage, cette peigneuse comprenant un dispositif d'alimentation, un dispositif d'arrachage, un dispositif de nettoyage des têtes de fibres et un dispositif de nettoyage des queues de fibres.Figure 1 of the accompanying drawings shows the combing machine rectilinear according to the invention, during the lifting phase, this combing machine comprising a feeding device, a lifting device, a fiber head cleaning device and a fiber cleaning device fiber tails.

    Le dispositif d'alimentation est constitué par le peigne alimentaire 1, qui est associé à une grille alimentaire 2, par une pince 3 formée par une mâchoire supérieure 4 coopérant avec une mâchoire inférieure 5 et par une tôle entre pince 6. La matière textile est déplacée par le dispositif d'alimentation ainsi constitué pour être amené en contact avec le dispositif de nettoyage des têtes de fibres, qui réalisent la phase de peignage desdites têtes de fibres.The feeding device consists of the comb food 1, which is associated with a food grid 2, by a clamp 3 formed by an upper jaw 4 cooperating with a jaw lower 5 and by a plate between clamp 6. The textile material is moved by the feed device thus formed to be brought into contact with the fiber head cleaning device, which performs the combing said fiber heads.

    La matière textile passe entre le peigne alimentaire 1 et la grille alimentaire 2, qui sont mobiles de telle façon qu'ils puissent être écartés l'un de l'autre et qu'ils puissent être déplacés ensemble, soit dans le sens de déplacement de la matière textile, soit dans le sens inverse du déplacement de la matière textile. En l'occurrence, pendant un cycle de machine, le peigne 1 s'écarte de la grille 2, puis le peigne et la grille reculent ensemble, le peigne est alors rapproché de la grille et les aiguilles du peigne traversent la matière textile. Ensuite, cet ensemble ainsi constitué avance en entraínant avec lui la matière textile, de façon à présenter les têtes de fibres 23 (figure 2) au dispositif de nettoyage des têtes de fibres et à procéder à l'alimentation d'une nouvelle frange de fibres.The textile material passes between the food comb 1 and the grid food 2, which are movable so that they can be spread apart on the other and that they can be moved together, either in the direction of displacement of the textile material, either in the opposite direction of the displacement of textile material. In this case, during a machine cycle, the comb 1 moves away from grid 2, then the comb and grid move back together, the comb is then brought closer to the grid and the needles of the comb pass through the textile material. Then, this set thus formed advances by training with it the textile material, so as to present the fiber heads 23 (figure 2) the fiber head cleaning device and feeding a new bang of fibers.

    A ce moment, la pince 3 se ferme et la mâchoire inférieure 5, qui est articulée au bâti 10 de la machine, est abaissée de manière à se rapprocher du dispositif de nettoyage des têtes de fibres. La mâchoire supérieure 4, qui est également articulée au bâti de la machine, est abaissée, afin de se rapprocher de la mâchoire inférieure 5, jusqu'à entrer en contact avec elle pour pincer les fibres situées entre les deux mâchoires 4 et 5 et pour les retenir, puis la mâchoire supérieure 4 poursuit son mouvement en direction du dispositif de nettoyage des têtes de fibres et entraíne avec elle la mâchoire inférieure 5. Ce déplacement de la mâchoire inférieure vers le peigne circulaire 7 s'effectue progressivement.At this time, the clamp 3 closes and the lower jaw 5, which is articulated to the frame 10 of the machine, is lowered so as to be move closer to the fiber head cleaning device. Jaw upper 4, which is also articulated to the frame of the machine, is lowered, in order to get closer to the lower jaw 5, until it comes into contact with it to pinch the fibers located between the two jaws 4 and 5 and to retain them, then the upper jaw 4 continues its movement in direction of the fiber head cleaning device and leads with it the lower jaw 5. This displacement of the lower jaw towards the circular comb 7 is carried out gradually.

    La phase de peignage des têtes de fibres commence alors et est réalisée par le dispositif de nettoyage des têtes de fibres, qui est constituée par le peigne circulaire 7, sous forme de cylindre garni sur toute sa périphérie d'aiguilles ou de dents 8 et dont la vitesse de rotation est continue et réglable, ce peigne étant monté sur un arbre de support 9, dont la disposition est fixe par rapport au bâti 10 de la machine. Ce dispositif de nettoyage comporte, en outre, une brosse cylindrique 11 garnie de poils, un doffer 12 garni de pointes métalliques et un peigne battant 13.The combing phase of the fiber heads then begins and is performed by the fiber head cleaning device, which consists by the circular comb 7, in the form of a cylinder filled over its entire periphery of needles or teeth 8 and whose speed of rotation is continuous and adjustable, this comb being mounted on a support shaft 9, the arrangement is fixed relative to the frame 10 of the machine. This device cleaning comprises, in addition, a cylindrical brush 11 furnished with bristles, a doffer 12 with metal spikes and a beating comb 13.

    Lors de leur rotation, les aiguilles ou les dents 8 du peigne circulaire 7 pénètrent dans les têtes de fibres 23 présentées par la pince 3 et en retire les fibres courtes et les impuretés (figure 2). La brosse cylindrique 11, dont les poils s'interpénètrent dans les aiguilles ou dans les dents 8 du peigne circulaire 7, tourne plus vite que ledit peigne circulaire 7, mais en sens inverse, de manière à retirer les fibres courtes et les impuretés transportées par les aiguilles ou les dents 8 du peigne circulaire 7 et de façon à le maintenir propre.During their rotation, the needles or teeth 8 of the comb circular 7 penetrate the fiber heads 23 presented by the clamp 3 and removes the short fibers and impurities (Figure 2). The cylindrical brush 11, the hairs of which interpenetrate in the needles or in the teeth 8 of the circular comb 7, rotates faster than said circular comb 7, but in opposite direction, so as to remove short fibers and impurities transported by the needles or the teeth 8 of the circular comb 7 and of way to keep it clean.

    Le doffer tourne moins vite que la brosse cylindrique 11 et en sens inverse de ladite brosse cylindrique 11 et ses pointes affleurent les poils de cette dernière et déchargent lesdits poils de ladite brosse cylindrique 11 des fibres courtes et des impuretés transportées par la brosse.The doffer rotates more slowly than the cylindrical brush 11 and in opposite direction of said cylindrical brush 11 and its points are flush with the bristles therefrom and discharge said bristles from said brush cylindrical 11 of short fibers and impurities transported by the brush.

    Le peigne battant 13 du dispositif de nettoyage des têtes de fibres est une lame qui est mise en oscillation à proximité des pointes du doffer 12, cette lame étant chargée de débarrasser les pointes du doffer 12 des fibres courtes et des impuretés qu'elles transportent. Les fibres courtes et les impuretés constituent la blousse, qui est récupérée par gravité et/ou par aspiration en vue de son évacuation.The beating comb 13 of the head cleaning device fibers is a blade that is oscillated near the tips of the doffer 12, this blade being responsible for ridding the tips of doffer 12 short fibers and the impurities they carry. Short fibers and the impurities constitute the shell, which is recovered by gravity and / or by suction for evacuation.

    La matière textile est ensuite déplacée par le dispositif d'alimentation pour être mise en contact avec le dispositif d'arrachage et avec le dispositif de nettoyage des queues de fibres, ces dispositifs réalisant les phases d'arrachage et de nettoyage des queues de fibres.The textile material is then moved by the device supply to be brought into contact with the lifting device and with the fiber tail cleaning device, these devices performing the tearing-out and cleaning phases of the fiber tails.

    Le dispositif d'arrachage est notamment constitué par un chariot 14, par une biellette 17, par un équipage mobile 18, par une paire de cylindres arracheurs 15 et 16, par un manchon d'arrachage 19 et par un cylindre de tension 20 (figure 1).The lifting device is in particular constituted by a carriage 14, by a link 17, by a mobile assembly 18, by a pair of lifting cylinders 15 and 16, by a lifting sleeve 19 and by a tension cylinder 20 (figure 1).

    Le chariot 14 est un levier, dont l'extrémité inférieure est articulée par un palier 24 sur le bâti 10 de la machine et dont l'extrémité supérieure est articulée, par l'intermédiaire d'un palier 25, à l'équipage mobile 18. La biellette 17 est un levier, dont l'extrémité inférieure est articulée par l'intermédiaire d'un palier 26 au bâti 10 de la machine et dont l'extrémité supérieure est articulée, par l'intermédiaire d'un palier 27, à l'équipage mobile 18. L'équipage mobile 18 est constitué par deux parties solidaires et coulissant l'une sur l'autre, non représentées dans le dessin annexé, dont l'une supporte le palier 25 de l'articulation haute du chariot 14 et dont l'autre supporte l'articulation haute 27 de la biellette 17.The carriage 14 is a lever, the lower end of which is articulated by a bearing 24 on the frame 10 of the machine and the end of which upper is articulated, via a bearing 25, to the crew mobile 18. The link 17 is a lever, the lower end of which is articulated by means of a bearing 26 to the frame 10 of the machine and of which the upper end is articulated, by means of a bearing 27, at the moving part 18. The moving part 18 is made up of two parts integral and sliding one on the other, not shown in the drawing annexed, one of which supports the bearing 25 of the upper articulation of the carriage 14 and the other of which supports the upper articulation 27 of the link 17.

    Le chariot 14 est animé d'un mouvement d'oscillation autour de son articulation basse 24 par l'intermédiaire d'un levier (non représenté) relié à un dispositif d'actionnement en va-et-vient. Ainsi, le chariot 14 peut se déplacer entre deux positions angulaires extrêmes séparées l'une de l'autre d'une distance appelée couramment la course du chariot. Dans l'une de ses deux positions extrêmes, l'extrémité supérieure du chariot 14 se situe à proximité du dispositif d'alimentation et, dans l'autre position extrême, l'équipage mobile 18 est à proximité d'une boíte à friser 28.The carriage 14 is driven in an oscillating movement around its low articulation 24 by means of a lever (not shown) connected to a back-and-forth actuation device. Thus, the carriage 14 can move between two separate extreme angular positions one of the other from a distance commonly called the carriage stroke. In one from its two extreme positions, the upper end of the carriage 14 is located near the feeder and, in the other extreme position, the moving element 18 is near a curling box 28.

    Dans sa partie supérieure, le chariot 14 supporte le cylindre arracheur inférieur 15, qui est commandé positivement en rotation selon une loi de mouvement dite du pas de pèlerin et qui est surmonté par le cylindre arracheur supérieur 16, le manchon d'arrachage 19 étant pincé entre les cylindres arracheurs 15 et 16.In its upper part, the carriage 14 supports the cylinder lower stripper 15, which is positively controlled in rotation according to a law of motion called the pilgrim's step and which is surmounted by the cylinder upper stripper 16, the stripping sleeve 19 being pinched between the lifting cylinders 15 and 16.

    L'équipage mobile 18 supporte, dans sa partie proche de la boíte à friser 28 le cylindre de tension 20 du manchon d'arrachage 19, qui est maintenu sous tension par écartement l'une de l'autre des deux parties coulissantes de l'équipage mobile 18. En outre, l'équipage mobile 18 supporte, entre le cylindre de tension 20 et un entonnoir de sortie 29, une paire de cylindres détacheur 30a et 30b et, au-dessus du manchon d'arrachage 19, une tôle sur manchon 31 et un cylindre anti-barbe 32.The mobile assembly 18 supports, in its part close to the curling box 28 the tension cylinder 20 of the tear-off sleeve 19, which is kept under tension by spacing one from the other of the two parts sliding of the moving part 18. In addition, the moving part 18 supports, between the tension cylinder 20 and an outlet funnel 29, a pair of detaching cylinders 30a and 30b and, above the sleeve tear 19, a sheet on sleeve 31 and an anti-beard cylinder 32.

    Lors de la phase d'arrachage des fibres, l'extrémité supérieure du chariot 14 se situe à proximité du dispositif d'alimentation et les cylindres arracheurs 15 et 16 associés au manchon d'arrachage 19 pincent l'extrémité des têtes de fibres 23 présentée par le dispositif d'alimentation. A cet effet, la pince 3 est ouverte et la tôle entre pince 6 est avancée dans le sens de déplacement des fibres, de manière à contraindre l'extrémité des têtes de fibres à se présenter entre les cylindres arracheurs 15 et 16. Ces derniers sont mis en rotation de façon à extraire les têtes de fibres du peigne alimentaire 1 et le chariot 14 est déplacé, afin de s'écarter de la pince 3.During the fiber grubbing phase, the upper end of the carriage 14 is located near the supply device and the lifting cylinders 15 and 16 associated with the lifting sleeve 19 pinch the end of the fiber heads 23 presented by the supply device. AT For this purpose, the clamp 3 is open and the sheet between clamp 6 is advanced in the direction of movement of the fibers, so as to constrain the end of the fiber heads to be presented between the tear-off cylinders 15 and 16. These the latter are rotated so as to extract the fiber heads from the comb food 1 and the carriage 14 is moved, in order to move away from the clamp 3.

    Le peignage des queues de fibres à l'aide du dispositif de nettoyage des queues de fibres sera effectué simultanément à ce déplacement desdites fibres. A cet effet, le dispositif de nettoyage des queues de fibres présente un peigne fixe 21 solidaire d'un levier articulé 22. Le peigne fixe 21 est approché des têtes de fibres 23 de telle manière que les aiguilles du peigne fixe 21, en traversant la matière, en retirent les impuretés pendant le déplacement de la matière par le dispositif d'arrachage. Les impuretés ainsi retenues sont récupérées par gravité et/ou par aspiration par le peigne circulaire 7 et un capteur pneumatique 33.Combing the tails of fibers using the cleaning of the fiber tails will be carried out simultaneously with this displacement of said fibers. To this end, the device for cleaning the fiber tails has a fixed comb 21 secured to an articulated lever 22. The fixed comb 21 is approached to the fiber heads 23 so that the needles of the fixed comb 21, passing through the material, remove the impurities during movement of the material by the device tear. The impurities thus retained are recovered by gravity and / or by suction with the circular comb 7 and a pneumatic sensor 33.

    Selon une autre caractéristique de l'invention, le peigne circulaire 7 est solidaire d'un arbre de support, non représenté, monté, avec possibilité de rotation, en porte-à-faux sur le bâti 10 de la machine, ce bâti présentant, du côté de l'extrémité libre de l'arbre de support, une ouverture autorisant l'extraction latérale du peigne circulaire. Cet arbre de support est mis en rotation par l'intermédiaire d'un moyen d'entraínement, tel qu'un pignon cranté, une roue dentée, une poulie lisse ou un moteur électrique, et assure le blocage axial et en rotation du peigne circulaire par l'intermédiaire de butées. Ce peigne circulaire 7 peut être monobloc ou en plusieurs parties et est formé par un cylindre, dont les deux extrémités sont montées sur des flasques solidarisés avec l'arbre de support.According to another characteristic of the invention, the comb circular 7 is integral with a support shaft, not shown, mounted, with possibility of rotation, cantilevered on the frame 10 of the machine, this frame having, on the side of the free end of the support shaft, an opening allowing lateral extraction of the circular comb. This support shaft is rotated by means of a drive, such as a toothed pinion, a gear wheel, a smooth pulley or an electric motor, and ensures the axial and rotational locking of the circular comb through of stops. This circular comb 7 can be in one piece or in several parts and is formed by a cylinder, the two ends of which are mounted on flanges secured to the support shaft.

    De manière connue, l'arbre de support peut également être monté en rotation sur deux roulements placés chacun sur le bâti, de part et d'autre du peigne circulaire.In known manner, the support shaft can also be rotatably mounted on two bearings, each placed on the frame, on both sides on the other side of the circular comb.

    Les figures 3 à 9 des dessins annexés représentent schématiquement des variantes de réalisation du peigne circulaire 7.Figures 3 to 9 of the accompanying drawings show schematically alternative embodiments of the circular comb 7.

    Ainsi, dans le mode de réalisation selon la figure 3, le peigne circulaire est constitué par un cylindre 34 sur lequel sont placées les aiguilles ou les dents 8. Dans le mode de réalisation selon les figures 4 à 6, le peigne circulaire est constitué par plusieurs portions en arc de cercle 34' pourvues chacune de dents ou aiguilles 8.Thus, in the embodiment according to FIG. 3, the comb circular consists of a cylinder 34 on which are placed the needles or teeth 8. In the embodiment according to FIGS. 4 to 6, the circular comb is formed by several portions in an arc of a circle 34 ′ each provided with teeth or needles 8.

    Les dents ou aiguilles 8 peuvent être de caractéristiques identiques (figures 3 à 6) ou différentes, mais sont disposées selon une séquence répétitive (figures 7 à 9). Teeth or needles 8 may be characteristic identical (Figures 3 to 6) or different, but are arranged in a repetitive sequence (Figures 7 to 9).

    Dans le mode de réalisation selon la figure 8, les dents ou aiguilles du peigne circulaire 7 sont réalisées par enroulement, selon un angle d'enroulement compris entre 55° et 125° par rapport à l'axe du peigne circulaire 7, d'un ou de plusieurs fils dentés 35, à spires jointives de caractéristiques A, B, C, D, etc...identiques ou différentes et dont les séquences se répètent périodiquement.In the embodiment according to FIG. 8, the teeth or needles of the circular comb 7 are produced by winding, according to a winding angle between 55 ° and 125 ° relative to the axis of the comb circular 7, of one or more toothed wires 35, with contiguous turns of characteristics A, B, C, D, etc ... identical or different and whose sequences are repeated periodically.

    Dans un tel cas, le peigne circulaire est préférentiellement réalisé par enroulement d'au moins un fil denté, à spires jointives, autour d'un cylindre, à la manière d'un tambour de carde. Lors d'un enroulement de plus d'un fil denté autour d'un cylindre , chaque fil denté peut présenter des caractéristiques différentes comme par exemple la densité, c'est à dire la distance séparant deux pointes consécutives, ou l'épaisseur du fil, ou encore la forme des dents. Dans un tel cas de fil denté enroulé autour d'un cylindre, on prendra garde à éviter, lors de la fabrication du peigne, la formation d'images, c'est-à-dire de zones périphériques locales de la garniture où les dents seraient disposées en lignes régulières par rapport à d'autres zones où les dents seraient disposées aléatoirement.In such a case, the circular comb is preferably made by winding at least one toothed wire, with contiguous turns, around a cylinder, like a card drum. When winding more than one toothed wire around a cylinder, each toothed wire may have different characteristics such as density, i.e. distance between two consecutive points, or the thickness of the wire, or the shape of the teeth. In such a case of toothed wire wrapped around a cylinder, take care to avoid, during the manufacture of the comb, the image formation, i.e. local peripheral areas of the trim where the teeth would be arranged in regular lines with respect to other areas where the teeth would be randomly arranged.

    Lorsque le peigne circulaire est réalisé en enroulant un ou plusieurs fils dentés autour d'un cylindre, on choisira, afin de le nettoyer à fond, un dispositif de nettoyage de garniture du type de ceux utilisés pour les tambours de carde et dont un exemple est connu par FR-A-2 705 367.When the circular comb is made by winding one or several toothed wires around a cylinder, we will choose, in order to clean it with bottom, a packing cleaning device of the type used for carding drums and an example of which is known from FR-A-2 705 367.

    Comme le montrent les figures,7 et 9, le peigne circulaire peut être réalisé par empilement de tôles découpées sous la forme de couronnes circulaires 36, dont la périphérie extérieure est pourvue de dents identiques ou de caractéristiques différentes A, B, C, etc... selon une séquence répétitive et dont la périphérie intérieure est munie de moyens de maintien permettant le centrage, l'entraínement en rotation et la fixation desdites couronnes (figure 7).As shown in Figures 7 and 9, the circular comb can be made by stacking cut sheets in the form of crowns circular 36, the outer periphery of which is provided with identical teeth or of different characteristics A, B, C, etc ... according to a sequence repetitive and whose inner periphery is provided with holding means allowing centering, rotational drive and fixing of said crowns (figure 7).

    Dans le cas d'une garniture obtenue par empilement de tôles découpées, on peut choisir, lorsque la garniture est montée sur plus d'une coquille partiellement cylindrique, d'empiler sur chacune des coquilles composant le peigne circulaire, des tronçons de couronnes circulaires 37 l'un contre l'autre(figure 6).In the case of a lining obtained by stacking sheets cut, you can choose, when the trim is mounted on more than one partially cylindrical shell, stack on each of the shells making up the circular comb, sections of circular crowns 37 one against the other (Figure 6).

    En outre, les dents ou aiguilles 8 du peigne circulaire 7 peuvent présenter une densité identique sur toute la périphérie dudit peigne circulaire 7 ou des densités différentes, par exemple par disposition suivant des lignes contiguës d'aiguilles ou de dents 8 de densités différentes. In addition, the teeth or needles 8 of the circular comb 7 can have an identical density over the entire periphery of said comb circular 7 or different densities, for example by following arrangement contiguous lines of needles or teeth 8 of different densities.

    La figure 10a des dessins schématiques annexés représente un cycle complet de 360 degrés de rotation d'une peigneuse rectiligne de type connu. La phase de peignage des têtes de fibres est désignée par « a » et l'angle de peignage des têtes associé à la phase « a » est désigné par « α ». L'angle « α » correspond à la fraction du cycle de la machine pendant laquelle est effectué le peignage des têtes de fibres. Cet angle de peignage des têtes est couramment de l'ordre de 130 degrés.Figure 10a of the accompanying schematic drawings shows a full 360 degree rotation cycle of a straight type combing machine known. The combing phase of the fiber heads is designated by “a” and the combing angle of the heads associated with phase "a" is designated by "α". The angle “α” corresponds to the fraction of the machine cycle during which is carried out the combing of the fiber heads. This combing angle heads is commonly in the range of 130 degrees.

    La figure 10b représente schématiquement le mouvement de rotation d'un peigne circulaire lors d'un cycle complet de rotation habituel sur des peigneuses rectilignes conventionnelles. L'angle « b » définit par l'arc actif de garniture du peigne circulaire correspondant à la longueur de la garniture d'aiguilles ou de dents qui sera utilisée lors de la phase de peignage des têtes de fibres et l'angle « β » définit l'arc actif de garniture du peigne. Sur une peigneuse rectiligne conventionnelle , cet angle de garniture de peigne est de l'ordre de 160 à 220 degrés. Le peigne circulaire effectuant exactement un tour par cycle de la machine , la vitesse angulaire de rotation du peigne est augmentée puis diminuée.FIG. 10b schematically represents the movement of rotation of a circular comb during a usual complete rotation cycle on conventional straight combers. The angle "b" defined by the active arc of the circular comb trim corresponding to the length of the trim of needles or teeth that will be used during the phase of combing the fiber heads and the angle "β" defines the active trim arc of the comb. On a conventional straight combing machine, this angle of comb trim is in the range of 160 to 220 degrees. The circular comb making exactly one revolution per machine cycle, the angular speed of rotation of the comb is increased then decreased.

    La figure 10c est une représentation schématique d'un exemple de réalisation conforme à l'invention. Dans cet exemple, le peigne circulaire effectue un tour complet de rotation pendant la phase de peignage des têtes de fibres, l'arc actif de garniture du peigne est égal à la circonférence du peigne et l'angle de garniture du peigne est de 360 degrés. La période de rotation du peigne circulaire par rapport au cycle de la machine est désignée par « p » et est exprimée en degrés ; la vitesse de rotation du peigne est constante.Figure 10c is a schematic representation of an example according to the invention. In this example, the comb circular performs a full rotation during the combing phase of the fiber heads, the active arc of the trim of the comb is equal to the comb circumference and the trim angle of the comb is 360 degrees. The period of rotation of the circular comb relative to the cycle of the machine is designated by "p" and is expressed in degrees; the speed of rotation of the comb is constant.

    La figure 10d représente une variante de réalisation de l'invention, dans laquelle le peigne circulaire effectue plus d'un tour de rotation pendant la phase de peignage des têtes de fibres, c'est à dire que « p < α ». L'arc actif de garniture du peigne est supérieur à la circonférence du peigne et la vitesse angulaire de rotation du peigne est constante.FIG. 10d represents an alternative embodiment of the invention, in which the circular comb performs more than one turn rotation during the combing phase of the fiber heads, i.e. "P <α". Active comb trim arc is greater than the circumference of the comb and the angular speed of rotation of the comb is constant.

    La figure 10e représente un autre exemple de réalisation conforme à l'invention, où le peigne circulaire effectue également plus d'un tour de rotation pendant la phase de peignage des têtes de fibres, mais où la vitesse angulaire du peigne est augmentée puis diminuée.FIG. 10e represents another example of embodiment according to the invention, where the circular comb also performs more than one turn during the combing phase of the fiber heads, but where the angular speed of the comb is increased then decreased.

    Dans le cas où la vitesse angulaire du peigne circulaire est constante, on désigne par « N », le nombre de tours qu'effectue le peigne circulaire par cycle de machine. Ainsi on a : N= 360 / P
       avec : « 360» degrés machine / cycle machine ; « p » degrés machine / tour de peigne et « N» tour de peigne / cycle machine.    In the case where the angular speed of the circular comb is constant, the number of turns made by the circular comb per machine cycle is designated by "N". So we have: N = 360 / P
    with: "360" machine degrees / machine cycle; "P" machine degrees / comb turn and "N" comb turns / machine cycle.

    La position angulaire, exprimée en degrés, qu'occupe le peigne circulaire au moment où la première ligne d'aiguilles ou de dents s'engage dans la tête des fibres au début de la phase de peignage des têtes de fibres est définie comme origine de l'arc actif de garniture du peigne.The angular position, expressed in degrees, that the comb occupies circular when the first line of needles or teeth engages in the head of the fibers at the start of the combing phase of the fiber heads is defined as the origin of the active comb lining arc.

    Conformément à une caractéristique de l'invention, la valeur « p» de la période de rotation du peigne circulaire 7 est choisie telle que l'arc actif de garniture du peigne 7, qui est la longueur de la garniture d'aiguilles ou de dents 8 utilisée lors de la phase de peignage des têtes de fibres, présente une origine, qui correspond à la position angulaire exprimée en degrés, qu'occupe le peigne circulaire 7 au moment où la première ligne d'aiguilles ou de dents 8 s'engage dans la tête des fibres au début de la phase de peignage des têtes de fibres, et qui est déphasée, d'un cycle de machine à l'autre, d'une valeur « k1 », exprimée en degrés, du peigne circulaire 7 correspondant au rapport : K1=360*360P According to a characteristic of the invention, the value "p" of the period of rotation of the circular comb 7 is chosen such that the active arc of the lining of the comb 7, which is the length of the lining of needles or teeth 8 used during the combing phase of the fiber heads, has an origin, which corresponds to the angular position expressed in degrees, occupied by the circular comb 7 at the moment when the first line of needles or teeth 8 engages in the head of the fibers at the start of the combing phase of the fiber heads, and which is phase shifted, from one machine cycle to another, by a value “k1”, expressed in degrees, of the corresponding circular comb 7 reporting : K1 = 360 * 360 P

    L'angle « k1 » augmente dans le sens de rotation du peigne. Ainsi, en considérant deux cycles consécutifs de la machine, ce n'est jamais la même ligne ou barrette d'aiguilles ou de dents qui, en s'engageant dans les têtes de fibres dépassant de la pince, déterminera l'origine de l'arc actif de garniture du peigne, qui sera utilisé lors de la phase de peignage des têtes.The angle "k1" increases in the direction of rotation of the comb. So, considering two consecutive machine cycles, it's never the same line or strip of needles or teeth which, when engaging in the fiber heads protruding from the clamp, will determine the origin of the active arc comb trim, which will be used during the combing phase of heads.

    Par ailleurs, le procédé consiste à choisir une origine relative de l'arc actif de garniture du peigne, k1', telle que k1' = k1 - [ENT( N ) * 360], et où ENT(N) représente la valeur entière du nombre N.Furthermore, the method consists in choosing a relative origin of the active comb lining arc, k1 ', such that k1' = k1 - [ENT (N) * 360], and where ENT (N) represents the integer value of the number N.

    En outre, on choisira préférentiellement une origine relative de l'arc actif de garniture du peigne telle que la variable « k1' » soit comprise entre 10 et 350 degrés. A cet effet, on préférera également des valeurs de « k1' »plutôt proches de 350 degrés et éloignées de 10 degrés.In addition, a relative origin of the active arc of the lining of the comb such that the variable "k1 '" is included between 10 and 350 degrees. For this purpose, we will also prefer values of "K1 '" rather close to 350 degrees and distant by 10 degrees.

    Dans l'exemple représenté à la figure 10c le peigne circulaire peut effectuer un tour complet lors de la phase de peignage des têtes de fibres et environ 2,77 tours par cycle de machine, soit, dans ce cas p = α = 130.1 degrés machine / tour de peigne et N = 2.77 tours de peigne / cycle machine.In the example shown in Figure 10c the circular comb can perform a full turn during the combing phase of the heads of fibers and around 2.77 revolutions per machine cycle, i.e. in this case p = α = 130.1 machine degrees / comb revolution and N = 2.77 comb revolutions / cycle machine.

    L'origine de l'arc actif de garniture du peigne de deux cycles consécutifs de la machine est déphasée à chaque cycle de k1 = 996.2 degrés c'est-à-dire relativement au peigne lui-même d'une valeur k1' = 276.2 degrés, obtenue par l'opération suivante : (996.2 - (2 * 360). Dans ce cas, lorsque la machine effectue un cycle, le peigne circulaire tournera de 996.2 degrés soit environ 2,77 tours, et la brosse cylindrique nettoiera 996.2 degrés du peigne circulaire, ce qui revient à dire que le peigne circulaire sera nettoyé environ 2,77 fois par cycle de la machine.The origin of the active arc of trim of the comb of two cycles consecutive times the machine is out of phase with each cycle of k1 = 996.2 degrees that is to say relative to the comb itself with a value k1 '= 276.2 degrees, obtained by the following operation: (996.2 - (2 * 360). In this case, when the machine cycles, the circular comb will turn 996.2 degrees or about 2.77 turns, and the cylindrical brush will clean 996.2 degrees of the circular comb, which means that the circular comb will be cleaned approximately 2.77 times per machine cycle.

    Sur une peigneuse rectiligne conventionnelle équipée d'un peigne circulaire avec un segment garni d'aiguilles à densité croissante, occupant une partie seulement de la périphérie du cylindre, on constate que l'origine de l'arc actif de garniture du peigne, la longueur de l'arc de la garniture du peigne et la période de rotation du peigne sont toujours les mêmes à chaque cycle de la machine. Les impuretés retirées par le segment garni, à savoir, les fibres trop courtes et les défauts tels que boutons et déchets végétaux qui sont retenues par les aiguilles ou les dents du segment garni sont localisées systématiquement et préférentiellement, d'une part près de l'origine de l'arc actif de garniture du peigne, car ce sont les premières aiguilles qui effectuent la plus grande part du nettoyage et, d'autre part, vers la fin de l'arc actif de garniture du peigne où les impuretés se retrouvent souvent coincées entre les aiguilles les plus fines et les plus serrées.On a conventional straight combing machine equipped with a circular comb with a segment filled with needles of increasing density, occupying only part of the periphery of the cylinder, it can be seen that the origin of the active comb lining arc, the length of the arc of the comb trim and the period of rotation of the comb are always the same at each cycle of the machine. Impurities removed by the segment trimmed, i.e., fibers too short and defects such as pimples and vegetable waste which is retained by the needles or the teeth of the segment garnished are located systematically and preferentially, on the one hand of the origin of the active comb lining arc, because these are the first needles that do most of the cleaning and on the other hand the end of the active arc of the lining of the comb where the impurities are found often caught between the thinnest and tightest needles.

    Ainsi, la brosse cylindrique qui est chargée de nettoyer le segment garni doit être capable de retirer d'entre les aiguilles, d'une part, une grande accumulation d'impuretés localisée près de l'origine de l'arc actif de garniture du peigne et, d'autre part, des impuretés coincées entre les aiguilles fines et serrées situées vers la fin de l'arc actif de garniture du peigne. A cet effet, la vitesse de rotation de la brosse cylindrique est supérieure à celle du peigne circulaire et les poils de la brosse doivent interpénétrer suffisamment les aiguilles du peigne circulaire, ce qui entraíne une usure rapide de ladite brosse cylindrique et des aiguilles du segment garni.Thus, the cylindrical brush which is responsible for cleaning the trimmed segment must be able to remove from the needles, on the one hand, a large accumulation of impurities located near the origin of the active arc of the trim of the comb and, on the other hand, of the impurities trapped between the fine and tight needles located towards the end of the active trim arc of the comb. For this purpose, the speed of rotation of the cylindrical brush is greater than that of the circular comb and the bristles of the brush should sufficiently interpenetrate the needles of the circular comb, which leads rapid wear of said cylindrical brush and the needles of the segment stocked.

    En effet, sur une peigneuse rectiligne conventionnelle, l'interpénétration des poils de la brosse avec les aiguilles du segment garni est élevée, car le segment garni n'est nettoyé qu'une seule fois par cycle de machine, puisqu'il ne passe qu'une fois par cycle en face des poils de la brosse cylindrique. Par ailleurs, les aiguilles du segment garni s'usent également rapidement au contact de la matière textile, car ce sont toujours les mêmes aiguilles qui sont chargées de la plus forte charge de nettoyage des têtes de fibres.Indeed, on a conventional straight combing machine, the interpenetration of the bristles of the brush with the needles of the trimmed segment is high because the trimmed segment is only cleaned once per cycle machine, since it only passes once per cycle in front of the bristles of the cylindrical brush. In addition, the needles of the trimmed segment wear out also quickly in contact with the textile material, because they are always the same needles that are loaded with the highest cleaning load fiber heads.

    La présente invention permet de remédier à ces inconvénients. En effet, l'origine de l'arc actif de garniture du peigne étant régulièrement décalée à chaque cycle de la machine ce ne sont jamais deux fois de suite les mêmes aiguilles ou dents du peigne circulaire qui s'engagent dans la tête des fibres au début de la phase de peignage des têtes. La longueur de l'arc actif de la garniture du peigne est réglable et proportionnelle au diamètre du peigne et à la période de rotation du peigne. La période de rotation du peigne est choisie de telle manière que le peigne circulaire effectue plus d'un tour de rotation par cycle de la machine. Ainsi l'arc actif de la garniture du peigne sera nettoyé plus d'une fois par cycle de la machine.The present invention overcomes these drawbacks. Indeed, the origin of the active comb lining arc being regularly shifted at each machine cycle it is never twice in a row the same needles or teeth of the circular comb which engage in the head fibers at the start of the head combing phase. The length of the arc active of the comb lining is adjustable and proportional to the diameter of the comb and the period of rotation of the comb. The rotation period of the comb is chosen in such a way that the circular comb performs more one rotation per machine cycle. So the active arc of the comb lining will be cleaned more than once per machine cycle.

    Le travail de nettoyage du peigne circulaire par la brosse cylindrique s'en trouve facilité et l'usure des poils de la brosse est réduite, car l'interpénétration des poils de la brosse avec les aiguilles du peigne circulaire peut être moins élevée. Simultanément, l'usure des aiguilles ou des dents du peigne circulaire est également réduite. Le peigne circulaire est mieux nettoyé et reste donc efficace plus longtemps. Il en résulte que le ruban peigné est de meilleure qualité, que les éléments mécaniques tels que les aiguilles ou dents du peigne circulaire et 1a brosse cylindrique ont une durée de vie augmentée et que les interventions de nettoyage du peigne circulaire, de remplacement de la brosse cylindrique ou des aiguilles ou dents du peigne circulaire sont moins fréquentes. Le rendement de la peigneuse et la charge ouvrière du personnel sont ainsi améliorés.The job of cleaning the circular comb with the brush cylindrical is facilitated and the wear of the bristles of the brush is reduced, because the interpenetration of the bristles of the brush with the needles of the comb circular may be lower. At the same time, the wear of the needles or teeth of the circular comb is also reduced. The circular comb is better cleaned and therefore remains effective longer. As a result, the combed tape is of better quality, than mechanical elements such as the needles or teeth of the circular comb and the cylindrical brush have a longer service life and that comb cleaning operations circular, replacing the cylindrical brush or needles or teeth of the circular comb are less common. The performance of the combing machine and the working load of the personnel are thus improved.

    La valeur « p » de la période de rotation du peigne circulaire 7 est, de préférence, de l'ordre de 130 degrés. Cette valeur « p » de la période de rotation du peigne circulaire sera avantageusement choisie parmi tous les nombres réels « k2 » tels que : k2= PPGCD(p,360) ≥ 4 où le PGCD (p, 360) est le plus grand commun diviseur des valeurs « p » et « 360» exprimés en degrés. The value "p" of the period of rotation of the circular comb 7 is preferably of the order of 130 degrees. This value "p" of the rotation period of the circular comb will advantageously be chosen from all the real numbers "k2" such as: k2 = P GCD (p, 360) ≥ 4 where the PGCD (p, 360) is the greatest common divisor of the “p” and “360” values expressed in degrees.

    Ainsi, par exemple, si la période de rotation du peigne circulaire est de 130 degrés, k2 sera égal à 13 et s'il est de 131 degrés, k2 sera égal à 131.So, for example, if the rotation period of the comb circular is 130 degrees, k2 will be equal to 13 and if it is 131 degrees, k2 will be equal to 131.

    La variable « k2 » représente le nombre de cycles machine au bout duquel la même ligne d'aiguilles ou barrette d'aiguilles du peigne circulaire s'engagera dans les têtes de fibres dépassant de la pince. Ainsi, lorsque la période de rotation du peigne circulaire est de 130 degrés, alors la même ligne d'aiguilles sera utilisée tous les 13 cycles de la machine.The variable “k2” represents the number of machine cycles at end of which the same line of needles or needle bar of the comb circular will engage in the fiber heads protruding from the clamp. So, when the rotation period of the circular comb is 130 degrees, then the same line of needles will be used every 13 cycles of the machine.

    De préférence on choisira une période de rotation du peigne circulaire telle que la variable « k2 » soit la plus grande possible de telle manière que la même ligne d'aiguille soit utilisée le moins souvent possible et que l'usure des aiguilles du peigne circulaire soit la plus régulière possible. Par ailleurs, il sera pris en considération une période de rotation du peigne circulaire telle que la variable « N » , qui correspond au nombre de tours que réalise le peigne circulaire pendant un cycle de machine soit la plus grande possible.Preferably we will choose a period of rotation of the comb circular such that the variable “k2” is as large as possible of such so that the same needle line is used as little as possible and that the wear on the needles of the circular comb is the most regular possible. In addition, a rotation period will be taken into account. of the circular comb such as the variable "N", which corresponds to the number of turns that the circular comb achieves during a machine cycle, i.e. as large as possible.

    Lorsque la valeur « p » est supérieure à « α » degrés, le peigne circulaire effectue moins d'un tour de rotation pendant la phase de peignage des têtes de fibres et, inversement, lorsque la valeur « p » est inférieure à « α » degrés, le peigne circulaire effectue plus d'un tour de rotation pendant la phase de peignage des têtes de fibres.When the "p" value is greater than "α" degrees, the comb circular performs less than one rotation during the combing phase fiber heads and, conversely, when the "p" value is less than "Α" degrees, the circular comb performs more than one rotation during the combing phase of the fiber heads.

    De préférence, le diamètre du peigne circulaire est inférieur à celui couramment employé. Son prix de fabrication s'en trouve réduit et sa manipulation est facilitée car son encombrement et son poids sont réduits. En outre, son faible encombrement permet, toutes choses restant égales par ailleurs, de ménager davantage de place entre le capteur pneumatique et le peigne circulaire.Preferably, the diameter of the circular comb is less than the one commonly used. Its manufacturing price is reduced and its handling is facilitated because its size and weight are reduced. In addition, its small footprint allows, all things remaining equal by elsewhere, to provide more space between the pneumatic sensor and the circular comb.

    De plus, du fait que le peigne circulaire est garni sur toute sa périphérie, par opposition aux peignes conventionnels équipés d'un segment garni et d'un segment non garni, il est parfaitement équilibré dynamiquement. Il peut être garni indifféremment d'aiguilles ou de dents, dont la taille et la densité sont choisies en fonction de la matière textile à travailler et de l'opération de peignage ou de repeignage à réaliser. Sa vitesse de rotation est préférentiellement uniformément constante ce qui entraíne un meilleur équilibrage global de la peigneuse.In addition, the fact that the circular comb is trimmed over its entire periphery, as opposed to conventional combs equipped with a segment garnished and an unfinished segment, it is perfectly balanced dynamically. It can be furnished either with needles or teeth, whose size and density are chosen according to the textile material to be work and the combing or repainting operation to be carried out. Her rotation speed is preferably uniformly constant which results in better overall balancing of the combing machine.

    De préférence, au peigne circulaire conforme à l'invention est associé un dispositif d'avance automatique de la brosse cylindrique tel que décrit dans FR-A-2 651 512 et qui est destiné à rattraper l'usure de la brosse cylindrique.Preferably, the circular comb according to the invention is associated with an automatic advance device of the cylindrical brush such as described in FR-A-2 651 512 and which is intended to compensate for the wear of the brush cylindrical.

    La charge de nettoyage du peigne circulaire par la brosse étant allégée, les poils de la brosse interpénètrent faiblement les aiguilles ou les dents du peigne circulaire de manière à les nettoyer. Périodiquement et pendant une faible durée, un dispositif automatique augmente la valeur d'interpénétration des poils de la brosse avec les dents du peigne circulaire de telle façon que les aiguilles ou les dents du peigne circulaire soient nettoyées à fond.The cleaning charge of the circular comb by the brush being lightened, the bristles of the brush weakly penetrate the needles or teeth of the circular comb so as to clean them. Periodically and for a short time, an automatic device increases the value of the bristles of the brush with the teeth of the circular comb in such a way that the needles or teeth of the circular comb are thoroughly cleaned.

    A l'issue de cette période de nettoyage en profondeur, le dispositif automatique réduit la valeur d'interpénétration, afin que la brosse retrouve la position qu'elle avait avant ladite période de nettoyage en profondeur. Ainsi, l'usure des poils de la brosse cylindrique est réduite et sa durée de vie est allongée.At the end of this deep cleaning period, the automatic device reduces the interpenetration value, so that the brush regains the position it had before said cleaning period in depth. Thus, the wear of the bristles of the cylindrical brush is reduced and its service life is extended.

    De préférence, selon une autre caractéristique de l'invention, et comme le montre la figure 2 des dessins annexés, la peigneuse rectiligne n'est pas pourvue d'une brosse enfonceuse de la tête des fibres 23. Une telle brosse enfonceuse est généralement chargée de contraindre la tête des fibres 23 à pénétrer entre les aiguilles ou les dents 8 du peigne circulaire 7. La mâchoire supérieure 4 de la pince 3 est alors avantageusement pourvue d'un dispositif enfonceur 4" muni d'une surface de détour 4', qui contraint la tête des fibres 23 à être orientée presque perpendiculairement à la tangente du peigne circulaire 7. Ce dispositif 4" présente, dans sa partie inférieure, une surface d'appui 4"' destinée à coopérer avec la tête des fibres 23 et à la contraindre à pénétrer entre les aiguilles ou les dents 8 du peigne circulaire 7, ladite surface d'appui 4''' s'étendant à partir de la surface de détour 4' sur une distance au moins égale à 5 mm.Preferably, according to another characteristic of the invention, and as shown in Figure 2 of the accompanying drawings, the straight combing machine is not provided with a brush for driving the head of the fibers 23. Such a driving brush is usually responsible for constraining the fiber head 23 to penetrate between the needles or the teeth 8 of the circular comb 7. The upper jaw 4 of the clamp 3 is then advantageously provided with a 4 "driving device with a 4 'detour surface, which forces the head fibers 23 to be oriented almost perpendicular to the tangent of the circular comb 7. This 4 "device has, in its lower part, a bearing surface 4 "'intended to cooperate with the head of the fibers 23 and to force to penetrate between the needles or the teeth 8 of the circular comb 7, said bearing surface 4 '' 'extending from the detour surface 4' on a distance at least equal to 5 mm.

    La surface d'appui 4''' du dispositif enfonceur 4" peut être plane ou curviligne. Dans ce dernier cas, son rayon de courbure est concentrique à celui du peigne circulaire 7.The 4 '' 'bearing surface of the 4 "driving device can be flat or curvilinear. In the latter case, its radius of curvature is concentric with that of the circular comb 7.

    Le dispositif enfonceur 4" peut faire partie intégrante de la mâchoire supérieure 4 de la pince 3 ou être amovible et est avantageusement réalisé dans le même matériau que la mâchoire supérieure 4, à savoir en un matériau métallique , plastique , ou composite.The 4 "driving device can be an integral part of the upper jaw 4 of the clamp 3 or be removable and is advantageously made of the same material as the upper jaw 4, namely a metallic, plastic, or composite material.

    Afin de peigner les têtes de fibres, la mâchoire supérieure 4, qui est articulée, est rapprochée de la mâchoire inférieure 5 jusqu'à la toucher et à pincer les fibres situées entre les deux mâchoires pour les retenir, puis la mâchoire supérieure poursuit son mouvement de rapprochement vers le peigne circulaire 7 et entraíne avec elle la mâchoire inférieure 5 jusqu'à une distance telle que la surface d'appui 4''' du dispositif enfonceur 4" affleure sans les toucher les aiguilles ou les dents 8 du peigne circulaire 7.In order to comb the fiber heads, the upper jaw 4, which is articulated, is brought closer to the lower jaw 5 until touching it and pinch the fibers between the two jaws to hold them, then upper jaw continues to move towards the circular comb 7 and carries with it the lower jaw 5 to a distance such that the bearing surface 4 '' 'of the driving device 4 "is flush without touching the needles or teeth 8 of the circular comb 7.

    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 différents 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 mode of embodiment described and shown in the accompanying drawings. Modifications remain possible, particularly from the point of view of the constitution of different elements or by substitution of technical equivalents, without leaving provided the scope of protection of the invention.
