Abstract

The nozzle has blades (23), each carrying a fabric string puller and situated in respective suction channels (19, 20), which are connected to a front suction orifice (7) that allows suction in a direction parallel to a surface to be cleaned. The blades are arranged in the internal side of the nozzle such that large wastes entering the nozzle pass above the blades by using upper surfaces of the channels.

Description

La présente invention concerne un suceur d'aspirateur à poussières, et plus particulièrement une amélioration de l'efficacité de collecte des déchets.The present invention relates to a dust vacuum cleaner nozzle, and in particular an improvement in the efficiency of waste collection.

Les suceurs d'aspirateur constituent des organes de collecte des déchets souillant la surface à nettoyer. Ils font donc l'objet de nombreux perfectionnements visant en particulier à améliorer une telle collecte.The vacuum cleaner nozzles are the collection organs for waste contaminating the surface to be cleaned. They are therefore the subject of numerous improvements aimed in particular at improving such collection.

Il est notamment connu, par exemple par le document DE3025977, d'utiliser un tissu arrache-fils à proximité de la zone d'aspiration du suceur, permettant de décrocher les fibres et fils que la force d'aspiration seule, créée par l'aspirateur, ne permet pas d'enlever.It is notably known, for example from the document DE3025977, use a wire stripper near the suction area of the squeegee, allowing to unhook the fibers and threads that the suction force alone, created by vacuum, does not remove.

Il est par ailleurs connu, notamment par le document DE1815059 un suceur rectangulaire possédant au niveau de la face frontale rectiligne du suceur, une multitude de canaux d'aspiration parallèles s'étendant sous la semelle du suceur. Un tel suceur favorise l'aspiration non seulement sous le suceur mais également légèrement devant le suceur grâce aux ouvertures frontales des canaux. Ainsi, des déchets volumineux peuvent être aspirés par l'intermédiaire de tels canaux.It is also known, in particular from document DE1815059 a rectangular nozzle having at the level of the rectilinear front face of the nozzle, a multitude of parallel suction channels extending under the squeegee sole. Such a nozzle promotes suction not only under the crevice but also slightly in front of the crevice thanks to the openings frontal channels. Thus, bulky waste can be vacuumed by through such channels.

Cependant, lorsque de telles ouvertures frontales sont présentes, il n'est généralement pas prévu, sur le trajet défini par les canaux résultant de ces ouvertures, de dispositifs d'arrache-fils, qui, par définition, sont situés au niveau de la semelle, pour être en contact avec la surface à nettoyer.However, when such front openings are present, it is not generally not planned, on the path defined by the channels resulting from these openings, of wire strippers, which by definition are located at the level of the sole, to be in contact with the surface to be cleaned.

La présente invention vise à remédier à ces problèmes à l'aide d'un suceur qui permet de présenter les deux fonctionnalités d'aspiration des gros déchets et de collecte des fils et fibres d'une manière simple et économique.The present invention aims to remedy these problems using a crevice tool which presents the two large suction functions waste and collection of yarns and fibers in a simple and economical way.

La présente invention est atteinte à l'aide d'un suceur d'aspirateur ouvert vers la surface à nettoyer par au moins un canal d'aspiration, le rebord avant du suceur présentant au moins un orifice frontal destiné à assurer une aspiration dans une direction sensiblement parallèle à la surface à nettoyer, ledit orifice frontal d'aspiration étant relié à l'un des canaux d'aspiration, la face inférieure dudit suceur comportant également au moins une lame portant un tissu arrache-fils, caractérisé en ce que cette lame est située dans ledit canal d'aspiration où est relié l'orifice frontal, ladite lame étant agencée dans la face inférieure du suceur en s'étendant d'un bord à l'autre du canal, de telle manière à ménager un espace supérieur dans le canal permettant aux gros déchets entrant dans le suceur de passer au-dessus de ladite lame.The present invention is achieved using an open vacuum nozzle towards the surface to be cleaned by at least one suction channel, the front edge the nozzle having at least one front orifice intended to ensure a suction in a direction substantially parallel to the surface to be cleaned, said front suction port being connected to one of the suction channels, the face bottom of said nozzle also comprising at least one blade carrying a thread-pulling fabric, characterized in that this blade is located in said channel suction where the front opening is connected, said blade being arranged in the face bottom of the squeegee extending from one edge to the other of the channel, in such a way to provide an upper space in the channel allowing large waste entering the squeegee to pass over said blade.

Ainsi, en disposant l'arrache-fils dans le canal d'aspiration, sur une lame de faible hauteur de manière à laisser un passage au-dessus de ladite lame, on permet aux gros déchets d'être aspirés sans que la lame ne vienne entraver leur circulation, tout en proposant une action efficace de la lame équipée de l'arrache-fils puisque celle-ci est disposée dans le canal d'aspiration, de sorte que son action mécanique sur le sol est immédiatement suivie d'une aspiration pour entraíner les déchets délogés de la structure du sol à traiter.Thus, by placing the wire puller in the suction channel, on a blade of low height so as to leave a passage above said blade, we allows large waste to be vacuumed without the blade coming to obstruct their circulation, while offering an effective action of the blade equipped with the wire puller since it is arranged in the suction channel, so that its mechanical action on the ground is immediately followed by aspiration to cause waste dislodged from the soil structure to be treated.

Avantageusement, le suceur est de forme sensiblement triangulaire, en présentant deux bords latéraux formant la pointe du suceur et un bord arrière, l'orifice frontal étant alors ménagé dans la pointe du suceur.Advantageously, the nozzle is of substantially triangular shape, in having two lateral edges forming the nozzle tip and a rear edge, the front orifice then being formed in the tip of the nozzle.

L'un des avantages de cette structure est, non seulement de pouvoir physiquement disposer le suceur dans les coins des pièces à nettoyer, mais également d'aspirer véritablement au niveau de la pointe et même légèrement en avant de cette pointe, par l'ouverture frontale ainsi ménagée. Une telle facilité d'utilisation évite principalement le recours à de petits accessoires de nettoyage que l'on dispose à la place du suceur pour accéder aux endroits étroits tels notamment les coins et recoins.One of the advantages of this structure is, not only to be able physically place the nozzle in the corners of the parts to be cleaned, but also to really suck at the tip and even slightly in front of this point, by the front opening thus formed. Such a ease of use mainly avoids the use of small accessories cleaning that is available in place of the squeegee to access places narrow such as the nooks and crannies.

Par ailleurs, il s'est avéré très pratique et facile de diriger la pointe vers les objets à ramasser ou les coins à nettoyer, puisque cette pointe est dans l'axe du tube, donc dans l'axe de la poussée lorsque le suceur est déplacé. L'intérêt est alors de pouvoir viser tout objet en champ libre et non pas uniquement dans les coins.Furthermore, it has proven to be very practical and easy to direct the point towards the objects to be picked up or the corners to be cleaned, since this point is in the axis of the tube, therefore in the axis of the thrust when the nozzle is moved. The interest is then to be able to target any object in free field and not only in the corners.

Selon cette configuration, le suceur comporte avantageusement deux canaux d'aspiration agencés le long des deux bords latéraux formant la pointe du suceur, les deux canaux se rejoignant dans la partie avant du suceur, la lame portant l'arrache-fils reliant les deux bords latéraux dans la partie de jonction des deux canaux.According to this configuration, the nozzle advantageously comprises two suction channels arranged along the two lateral edges forming the point of the squeegee, the two channels joining in the front part of the squeegee, the blade carrying the wire puller connecting the two lateral edges in the part of junction of the two channels.

Cette structure permet de ménager une large zone d'aspiration vers l'avant du suceur, la lame portant l'arrache-fils située dans cette zone permettant d'ajouter une action mécanique au coeur de l'aspiration.This structure makes it possible to provide a large suction area towards the front of the squeegee, the blade carrying the wire puller located in this area allowing to add a mechanical action to the heart of the aspiration.

Avantageusement, la lame est sensiblement parallèle au bord arrière du suceur, améliorant ainsi l'efficacité de raclage du sol par cette lame.Advantageously, the blade is substantially parallel to the rear edge of the crevice tool, thus improving the scraping efficiency of the soil by this blade.

Avantageusement, le suceur comporte un capot présentant une zone de visualisation du sol située sous la semelle, ladite zone englobant la lame portant l'arrache-fils, permettant de contrôler que des déchets ne restent pas bloqués dans le suceur au niveau de ladite lame.Advantageously, the nozzle has a cover having a zone of visualization of the ground located under the sole, said zone encompassing the blade carrying the wire puller, allowing to check that waste does not remain blocked in the squeegee at the level of said blade.

D'autres caractéristiques et avantages de l'invention ressortiront de la description qui va suivre, prise à titre d'exemple non limitatif, en référence aux figures annexées dans lesquelles :

  • la figure 1 présente, dans une vue schématique de dessus, un suceur conforme à la présente invention,
  • la figure 2 présente une vue de dessous de certaines parties constitutives d'un suceur selon l'invention,
  • les figures 3 et 4 représentent, en perspective, respectivement une vue de dessus et de dessous de certaines parties constitutives d'un suceur selon l'invention.
Other characteristics and advantages of the invention will emerge from the description which follows, taken by way of nonlimiting example, with reference to the appended figures in which:
  • FIG. 1 shows, in a schematic top view, a nozzle according to the present invention,
  • FIG. 2 presents a bottom view of certain constituent parts of a nozzle according to the invention,
  • Figures 3 and 4 show, in perspective, respectively a top view and a bottom view of certain constituent parts of a nozzle according to the invention.

La présente invention concerne un suceur 1 d'aspirateur. Un tel suceur possède un tube de liaison 2 de raccordement à un corps d'aspirateur, non représenté, possédant notamment un moto-ventilateur susceptible de créer un flux d'aspiration d'air.The present invention relates to a vacuum cleaner nozzle 1. Such a sucker has a connecting tube 2 for connection to a vacuum cleaner body, not shown, including a motor fan capable of creating a air suction flow.

Le tube de liaison 2 débouche au niveau de la semelle 11 du suceur en contact avec le sol 4 à nettoyer, par l'intermédiaire d'un conduit de raccordement 3. Ce conduit débouche sur les canaux d'aspiration. Ces canaux sont généralement configurés selon la forme du suceur, afin d'optimiser l'efficacité d'aspiration. Dans l'exemple présenté où le suceur est de forme triangulaire, les canaux d'aspiration, tels que représentés par les pointillés 10, s'étendent en partie le long des deux bords 5, 6 formant la pointe du suceur, ainsi que dans ladite pointe du suceur après s'être rejoints dans la partie centrale du suceur.The connecting tube 2 opens at the level of the sole 11 of the nozzle contact with the floor 4 to be cleaned, via a connection 3. This duct opens onto the suction channels. These channels are generally configured according to the shape of the squeegee, in order to optimize suction efficiency. In the example presented where the nozzle is shaped triangular, the suction channels, as represented by the dotted lines 10, extend partly along the two edges 5, 6 forming the tip of the nozzle, as well as in said nozzle tip after joining in the part central nozzle.

Selon une caractéristique importante de l'invention, la zone angulaire formant la pointe du suceur comporte un orifice frontal 7 destiné à assurer une aspiration dans une direction sensiblement parallèle à la surface à nettoyer.According to an important characteristic of the invention, the angular zone forming the nozzle tip has a front opening 7 intended to ensure a suction in a direction substantially parallel to the surface to be cleaned.

Par ailleurs, dans la forme de réalisation présentée, le suceur possède des brosses escamotables actionnées par une pédale 8 pivotante. Cette pédale 8 est accessible au niveau du capot 12 du suceur. Ce dernier, dans cet exemple de réalisation, ne présente essentiellement que des fonctions esthétiques et de protection de l'environnement.Furthermore, in the embodiment presented, the nozzle has retractable brushes actuated by a pivoting pedal 8. This pedal 8 is accessible at the cover 12 of the squeegee. The latter, in this exemplary embodiment, essentially presents only functions aesthetic and environmental protection.

En effet, les canaux d'aspiration sont fermés, d'une part par une structure interne réalisée en partie lors de la fabrication par moulage de la semelle, telles les parties des canaux d'aspiration s'étendant le long des bords et débouchant par l'ouverture 7, mais également par une pièce supérieure 14 qui, selon l'exemple de réalisation, est une zone de visualisation réalisée en rendant transparente la pièce triangulaire rapportée sur la semelle.Indeed, the suction channels are closed, on the one hand by a internal structure produced in part during the manufacture by molding of the soleplate, such as the parts of the suction channels extending along the edges and opening through the opening 7, but also through an upper part 14 which, according to the exemplary embodiment, is a viewing area produced in making the triangular piece attached to the sole transparent.

Une telle particularité permet de visualiser les déchets 16 de la surface en cours de nettoyage. Selon la forme du suceur et du ou des canaux d'aspiration, cette zone de visualisation peut couvrir un champ plus important que celui du canal d'aspiration, afin d'ajuster la visée des déchets à extraire du sol.Such a feature makes it possible to view the waste 16 from the surface during cleaning. Depending on the shape of the squeegee and the channel (s) this viewing area can cover a larger field than that of the suction channel, in order to adjust the aim of the waste to be extracted from the ground.

Avantageusement, la zone de visualisation possède un effet de loupe, en présentant une forme convexe. Ainsi, les déchets sous la zone de visualisation sont grossis, améliorant ainsi la visualisation de la surface à nettoyer. Advantageously, the viewing area has a magnifying glass effect, with a convex shape. So the waste under the area of visualization are magnified, thus improving the visualization of the surface to clean.

La zone de visualisation de la surface en cours de nettoyage est préférentiellement de forme triangulaire, rappelant la forme générale du suceur, ce qui permet d'associer la zone de visualisation aux avantages d'utilisation liés à la forme triangulaire du suceur (maniement plus facile notamment).The viewing area of the surface being cleaned is preferably triangular in shape, recalling the general shape of the nozzle, which allows you to associate the viewing area with the associated advantages of use the triangular shape of the squeegee (easier handling in particular).

A ces fins de visualisation, le capot présente, à l'aplomb de la zone de visualisation, soit une simple ouverture, soit une fenêtre transparente réalisée, par exemple, en matière plastique.For these visualization purposes, the cover presents, directly above the area of display, either a simple opening, or a transparent window made, for example, plastic.

La pièce 14 comporte, par ailleurs, une partie arrière en relation avec l'extrémité du conduit de raccordement 3.The part 14 also comprises a rear part in relation to the end of the connection pipe 3.

Les figures 2 et 4 présentent le suceur vu de dessous. Ainsi la semelle 11 du suceur comporte plusieurs canaux d'aspiration : un canal 19 sensiblement parallèle au bord 6 du suceur, un canal 20 sensiblement parallèle au bord 5 du suceur. Ces canaux se rejoignent dans la région centrale 21 du suceur. Les canaux 19 et 20 possèdent des ouvertures frontales, c'est à dire dans les rebords verticaux de la semelle, respectivement 36 et 35, permettant une aspiration latérale sensiblement parallèle à la surface à nettoyer.Figures 2 and 4 show the squeegee seen from below. So the sole 11 of the squeegee has several suction channels: a channel 19 substantially parallel to the edge 6 of the nozzle, a substantially parallel channel 20 at edge 5 of the squeegee. These channels meet in the central region 21 of the nozzle. Channels 19 and 20 have front openings, i.e. in the vertical edges of the sole, respectively 36 and 35, allowing a lateral suction substantially parallel to the surface to be cleaned.

La forme triangulaire est complétée, à l'arrière du suceur, par une partie pleine 40 comportant deux emplacements 42 de moyens favorisant le déplacement du suceur, qui peuvent être, soit des patins de type PTFE, soit des roues.The triangular shape is completed, at the back of the nozzle, by a part full 40 comprising two locations 42 of means promoting the displacement of the squeegee, which can be either PTFE type pads or wheels.

Selon l'invention, une lame 23 s'étend dans cette région 21, du bord 5 du suceur au bord 6, définissant ainsi un canal avant 18 et un canal arrière 22, le canal avant 18 débouchant à la pointe du suceur par l'ouverture 7 frontale. Cette lame 23 comporte une zone 24 où est disposé un tissu arrache-fils tel qu'il est en soi connu.According to the invention, a blade 23 extends in this region 21, from the edge 5 from the squeegee at the edge 6, thus defining a front channel 18 and a rear channel 22, the front channel 18 emerging at the tip of the nozzle by the front opening 7. This blade 23 has a zone 24 where a wire-stripping fabric is arranged such that it is known per se.

Une des caractéristiques principales de cette lame 23 est de relier le bord 5 au bord 6 tel un pont, en ménageant un espace entre la face opposée à la zone 24 et la pièce supérieure 14. Cette lame est préférentiellement parallèle au bord arrière 9 du suceur. Il est en effet intéressant que cette lame soit orientée perpendiculairement au sens de déplacement du suceur le plus fréquent. Or l'axe de poussée principal du suceur, compte tenu de l'emplacement du tube de liaison 2 et du conduit de raccordement 3, aboutit à un déplacement « naturel » du suceur selon une direction perpendiculaire au bord arrière 9.One of the main characteristics of this blade 23 is to connect the edge 5 to edge 6 like a bridge, leaving a space between the face opposite zone 24 and upper part 14. This blade is preferably parallel at the rear edge 9 of the squeegee. It is indeed interesting that this blade is oriented perpendicular to the direction of movement of the squeegee frequent. Now the main thrust axis of the squeegee, taking into account the location of the connecting tube 2 and the connecting conduit 3, leads to a "natural" displacement of the squeegee in a direction perpendicular to the rear edge 9.

Une seconde zone 28 portant un tissu arrache-fils peut être prévue sur une bordure du canal 22, de façon symétrique à la zone 24 portant l'arrache-fils.A second zone 28 carrying a thread-pulling fabric can be provided on an edge of the channel 22, symmetrically to the zone 24 carrying the wire puller.

Dans une même idée de sollicitation efficace des fibres du sol, les canaux 19 et 20 possèdent, respectivement, de fines lames de raclage 46 et 45 s'étendant respectivement depuis le bord 6 et le bord 5 en direction de l'autre bord. Selon l'exemple proposé, ces lames sont fixes et issues de la semelle en s'étendant sensiblement parallèlement au bord arrière 9 sur une distance voisine de la moitié de la largeur du canal. Avantageusement, l'espace entre chaque petite lame est peu profond et défini par un bord présentant une déclivité orientée vers le canal, afin de limiter au maximum les zones de coincement éventuel des déchets.In the same idea of effective solicitation of soil fibers, the channels 19 and 20 have, respectively, fine scraper blades 46 and 45 extending respectively from edge 6 and edge 5 towards each other edge. According to the example proposed, these blades are fixed and come from the sole in extending substantially parallel to the rear edge 9 over a distance about half the width of the canal. Advantageously, the space between each small blade is shallow and defined by an edge having a slope oriented towards the canal, in order to minimize the areas of possible jamming of waste.

La semelle 11 comporte également des emplacements 25, 26 (cf. fig.3) pour des brosses escamotables 55, 56, 57 (cf. fig. 2 et 4), ces brosses bordant avantageusement les canaux d'aspiration.The sole 11 also has locations 25, 26 (see fig. 3) for retractable brushes 55, 56, 57 (cf. fig. 2 and 4), these brushes bordering advantageously the suction channels.

En fonctionnement, le suceur est déplacé sur le sol 4 à nettoyer, préférentiellement selon une direction perpendiculaire au bord arrière 9, l'utilisateur dirigeant le suceur vers les zones à nettoyer en se servant, même inconsciemment, de la pointe du suceur comme guide. Par la présence de l'ouverture frontale 7 dans la pointe du suceur, les plus gros déchets peuvent être aspirés sans qu'il soit nécessaire de soulever le suceur pour les collecter.In operation, the squeegee is moved to the floor 4 to be cleaned, preferably in a direction perpendicular to the rear edge 9, the user directs the nozzle to the areas to be cleaned, using even unconsciously, from the tip of the nozzle as a guide. By the presence of the front opening 7 in the tip of the nozzle, the largest waste can be vacuumed without the need to lift the squeegee to collect them.

Par la suite, ces déchets passent au-dessus de la lame 23 portant l'arrache-fils, selon la direction F. Ils sont ensuite dirigés vers le corps de l'aspirateur en quittant le suceur par le conduit de raccordement 3. La zone de visualisation 14 permet d'éventuellement contrôler que certains déchets ne restent pas bloqués au niveau de la lame. Subsequently, this waste passes over the blade 23 carrying the wire puller, in direction F. They are then directed towards the body of the vacuum cleaner leaving the squeegee through the connection duct 3. The display 14 allows you to possibly check that certain waste does not do not remain blocked at the level of the blade.

Les fils et fibres restant accrochés sur le sol sont sollicités par l'arrache-fils de la lame 23 qui présente l'avantage d'être bordé par les deux canaux 18 et 22 d'aspiration. Ainsi que le suceur soit déplacé vers l'avant ou vers l'arrière, la sollicitation du sol par l'arrache-fils sera, dans les deux cas, immédiatement suivie, dans le mouvement du suceur, par une aspiration.The threads and fibers remaining hanging on the ground are stressed by the thread puller of the blade 23 which has the advantage of being bordered by the two channels 18 and 22 suction. Whether the squeegee is moved forward or backward, the solicitation of the ground by the wire puller will, in both cases, immediately followed, in the movement of the squeegee, by an aspiration.

Par ailleurs, le positionnement de lame arrache-fils 23 dans l'axe de poussée et de visée du suceur, permet d'exercer l'action de l'arrache-fils effectivement où l'utilisateur le souhaite.Furthermore, the positioning of the wire stripper blade 23 in the axis of push and aim of the squeegee, allows to exert the action of the wire puller actually where the user wants it.

De plus, la seconde zone 28 portant l'arrache-fils permet, lorsque le suceur est déplacé vers l'arrière, de créer, dans ce sens de déplacement, deux processus de sollicitation du sol suivis d'une aspiration : l'un par sollicitation de l'arrache-fils de la zone 28 suivie d'une aspiration par le canal 22, l'autre par sollicitation de l'arrache-fils de la lame 23 suivie d'une aspiration par le canal 18. Cette double sollicitation permet d'augmenter l'efficacité de récolte des fibres et fils sur le sol à nettoyer selon le sens de déplacement arrière du suceur, étant connu que l'utilisateur a tendance, lorsqu'il déplace le suceur vers l'arrière, à soulever le suceur, au contraire du déplacement vers l'avant qui, lui, a tendance à enfoncer le suceur dans le sol, augmentant par-là même l'efficacité d'extraction des fibres et fils par l'arrache-fils.In addition, the second zone 28 carrying the wire puller allows, when the squeegee is moved backwards, creating, in this direction of movement, two solicitation process followed by aspiration: one by soliciting the wire puller in zone 28 followed by suction through channel 22, the other by stress on the wire puller of blade 23 followed by suction through the channel 18. This double solicitation increases the harvesting efficiency of fibers and threads on the floor to be cleaned according to the direction of rearward movement of the squeegee, being known that the user tends to move the squeegee towards the rear, to lift the squeegee, unlike the forward movement which, tends to sink the squeegee into the soil, thereby increasing the extraction efficiency of fibers and threads by the thread puller.

Dans une version perfectionnée de réalisation de l'invention, les zones d'arrache-fils 28 et 24 sont constituées de poils inclinés placés face à face avec l'inclinaison des poils vers le canal 22 pour les deux zones. A l'aller l'arrache-fils 28 accroche les cheveux alors que l'arrache-fils 24 laisse s'échapper les cheveux vers le canal 22 et au retour c'est l'arrache-fils 24 qui accroche les cheveux alors que l'arrache-fils 28 libère les cheveux vers le même canal 22.In an improved version of the invention, the zones wire pullers 28 and 24 consist of inclined bristles placed face to face with the inclination of the bristles towards the channel 22 for the two zones. On the go the wire puller 28 hangs the hair while the wire puller 24 lets out the hair towards channel 22 and on return it is the wire puller 24 which hooks the hair while the wire puller 28 releases the hair towards the same channel 22.

Par ailleurs, afin de palier à la différence d'enfoncement entre l'aller et le retour, on peut prévoir les deux arrache-fils à des hauteurs différentes en les plaçant sur un plan incliné. Cela permet d'avoir un positionnement des arrache-fils adapté à la grande majorité des moquettes du commerce sur lesquelles l'enfoncement du suceur n'est pas constant : sur une moquette assez dense ou bouclée, l'enfoncement est moins important que sur une moquette « touffetée » moins dense.Furthermore, in order to compensate for the difference in penetration between the outward and the back, we can provide the two wire pullers at different heights by placing on an inclined plane. This allows positioning of the wire pullers suitable for the vast majority of commercial carpets on which the squeegee sinking is not constant: on a fairly dense carpet or looped, sinking is less important than on a "tufted" carpet less dense.

Par ailleurs, la zone d'aspiration à l'avant peut permettre dans certains cas où l'arrache-fils 24 ne parviendrait pas à accrocher les fibres et/ou libèrerait un paquet de fibres, de pouvoir l'aspirer et éviter ainsi de laisser ces déchets sur le sol.In addition, the suction area at the front can allow in certain case where the thread puller 24 fails to catch the fibers and / or releases a bundle of fibers, to be able to vacuum it up and thus avoid leaving this waste On the ground.
