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 suction nozzle, and more particularly to an improvement of the waste collection efficiency.

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.Vacuum suckers are waste collection devices that contaminate the surface to be cleaned. They are therefore the object of many improvements aimed in particular to improve 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 particularly known, for example by the document DE3025977 , to use a wire pulling fabric near the suction zone of the nozzle, to pick up the fibers and son that the suction force alone, created by the vacuum cleaner, 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.He is moreover known, in particular by the document DE1815059 a rectangular nozzle having at the rectilinear front face of the nozzle, a plurality of parallel suction channels extending under the sole of the nozzle. Such a nozzle promotes suction not only under the nozzle but also slightly in front of the nozzle through the front openings of the channels. Thus, bulky waste can be sucked 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 frontal openings are present, it is generally not provided, in the path defined by the channels resulting from these openings, teardrop devices, which, by definition, are located at the sole , to be in contact with the surface to be cleaned.

WO-A-99/35951 divulgue un suceur d'aspirateur selon le préambule de la revendication indépendante. WO-A-99/35951 discloses a vacuum cleaner according to the preamble of the independent claim.

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 with the aid of a nozzle which makes it possible to present the two functions of suction of large waste and collection of son 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 with the aid of a suction nozzle open to the surface to be cleaned by at least one suction channel, the front edge of the nozzle having at least one front orifice intended to provide suction in one direction. substantially parallel to the surface to be cleaned, said front suction port being connected to one of the suction channels, the underside of said nozzle also having at least one blade carrying a tear-off fabric, characterized in that said blade is located in said suction channel wherein is connected the front orifice, said blade being arranged in the underside of the nozzle extending from one edge to the other of the channel, so as to provide an upper space in the channel for large waste entering the the nozzle 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 entraîner les déchets délogés de la structure du sol à traiter.Thus, by arranging the pull-son in the suction channel on a blade of low height so as to leave a passage above said blade, the large waste is allowed to be sucked without the blade comes from to hinder their circulation, while proposing effective action of the blade equipped with the pull-out son since it is arranged in the suction channel, so that its mechanical action on the ground is immediately followed by a suction for result in dislodged waste 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, having two lateral edges forming the tip of the nozzle 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 physically have the nozzle in the corners of the parts to be cleaned, but also to suck really at the tip and even slightly ahead of this tip, through the opening frontal thus arranged. Such ease of use primarily avoids the use of small cleaning accessories that are available instead of the nozzle to access narrow places such as 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.Moreover, it has proved very practical and easy to direct the tip towards the objects to pick up or corners to clean, since this tip is in the axis of the tube, so 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 tip of the nozzle, the two channels joining in the front part of the nozzle, the blade carrying the pull-son connecting the two side edges in the joining part 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 allows to provide a large suction zone towards the front of the nozzle, the blade carrying the pull-son located in this area to add a mechanical action in the heart of the suction.

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 nozzle, 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 comprises a hood having a soil viewing area located under the sole, said area including the blade carrying the pull-son, to control that waste does not remain blocked in the nozzle at 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 features and advantages of the invention will emerge from the description which follows, taken by way of non-limiting example, with reference to the appended figures in which:
  • the figure 1 presents, in a schematic view from above, a nozzle according to the present invention,
  • the figure 2 shows a view from below of certain constituent parts of a nozzle according to the invention,
  • the figures 3 and 4 represent, in perspective, respectively a view from above and from below 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 nozzle 1. Such a nozzle has a connection tube 2 connecting to a vacuum cleaner body, not shown, including a motor-fan capable of creating an air intake 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 sole 11 of the nozzle in contact with the ground 4 to be cleaned, via a conduit of connection 3. This duct opens on the suction channels. These channels are generally configured according to the shape of the nozzle, in order to optimize the suction efficiency. In the example presented in which the nozzle is of triangular shape, the suction channels, as represented by the dots 10, extend in part along the two edges 5, 6 forming the tip of the nozzle, as well as in said tip of the nozzle after joining in the central part of the 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 tip of the nozzle comprises a front orifice 7 intended to ensure 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.Moreover, in the embodiment shown, the nozzle has retractable brushes actuated by a pedal 8 pivoting. This pedal 8 is accessible at the hood 12 of the nozzle. The latter, in this embodiment, has essentially only aesthetic functions 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 an internal structure made in part during the manufacture by molding of the sole, such as the parts of the suction channels extending along the edges and opening through the opening 7, but also by an upper part 14 which, according to the embodiment, is a viewing area made by making transparent the triangular piece attached to the sole.

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 allows to view the waste 16 of the surface being cleaned. Depending on the shape of the nozzle and the suction channel or channels, this viewing area may cover a larger field than that of the suction channel, in order to adjust the target 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 effect, having a convex shape. Thus, the waste under the viewing area is magnified, improving the visualization of the surface to be cleaned.

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 zone of visualization of the surface being cleaned is preferably of triangular shape, recalling the general shape of the nozzle, which makes it possible to associate the viewing area with the advantages of use related to the triangular shape of the nozzle (easier handling especially).

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 has, directly above the viewing area, either a simple opening or a transparent window made, for example, of plastic.

La pièce 14 comporte, par ailleurs, une partie arrière en relation avec l'extrémité du conduit de raccordement 3.The part 14 also has a rear part in relation to the end of the connecting 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.The Figures 2 and 4 present the nozzle seen from below. Thus the sole 11 of the nozzle has several suction channels: a channel 19 substantially parallel to the edge 6 of the nozzle, a channel 20 substantially parallel to the edge 5 of the nozzle. These channels meet in the central region 21 of the nozzle. The channels 19 and 20 have front openings, that is to say in the vertical flanges 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 rear of the nozzle, by a solid portion 40 having two locations 42 means promoting the displacement of the nozzle, which may 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 of the nozzle to the edge 6, thus defining a front channel 18 and a rear channel 22, the front channel 18 opening at the tip of the nozzle by the front opening 7. This blade 23 has a zone 24 where is disposed a pull-wire fabric as 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 the edge 6 as a bridge, by providing a space between the face opposite the zone 24 and the upper part 14. This blade is preferably parallel to the rear edge 9 of the nozzle . It is indeed interesting that this blade is oriented perpendicularly to the direction of movement of the nozzle. frequent. Or the main thrust axis of the nozzle, given the location of the connecting tube 2 and the connecting pipe 3, results in a "natural" displacement of the nozzle 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 pull-out fabric may be provided on a border of the channel 22, symmetrically to the zone 24 carrying the pull-son.

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 the soil fibers, the channels 19 and 20 have, respectively, thin scraping blades 46 and 45 respectively extending from the edge 6 and the edge 5 towards the other edge. According to the proposed example, these blades are fixed and coming from the sole extending substantially parallel to the rear edge 9 over a distance of half the width of the channel. Advantageously, the space between each small blade is shallow and defined by an edge having a slope oriented towards the channel, in order to minimize the possible areas of jamming 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 (cf. fig.3 ) for retractable brushes 55, 56, 57 (cf. Fig. 2 and 4 ), these brushes advantageously bordering 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 nozzle is moved on the floor 4 to be cleaned, preferably in a direction perpendicular to the rear edge 9, the user directing the nozzle to the areas to be cleaned by using, even unconsciously, 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 sucked without the need to lift the nozzle 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 pull-son, in the direction F. They are then directed to the body of the vacuum cleaner leaving the nozzle through the connecting pipe 3. The zone visualization 14 can optionally control that some waste does not remain blocked at 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 son and fibers remaining on the ground are solicited by the pull-son of the blade 23 which has the advantage of being bordered by the two channels 18 and 22 suction. As the squeegee is moved forwards or backwards, the solicitation of the soil by the pull-son will, in both cases, immediately be 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.In addition, the positioning of the tear-off blade 23 in the thrust and aiming axis of the nozzle, makes it possible to exert the action of the pull-out actually where the user wishes 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 pull-out allows, when the nozzle is moved backwards, to create, in this direction of movement, two processes of solicitation of the soil followed by suction: one by solicitation of the son-puller of the zone 28 followed by aspiration by the channel 22, the other by solicitation of the pull-son of the blade 23 followed by suction by the channel 18. This double bias allows to increase the harvesting efficiency of the fibers and yarns on the floor to be cleaned according to the direction of rearward movement of the nozzle, it being known that the user tends, when moving the nozzle towards the rear, to lift the nozzle , contrary to the forward movement which, he, tends to drive the nozzle in the ground, thereby increasing the efficiency of extraction of fibers and son by the pull-son.

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 embodiment of the invention, the tear-off zones 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 pull-out 28 hooks the hair while the pull-son 24 lets out the hair to the channel 22 and in return it is the pull-son 24 which hangs the hair while the The puller 28 releases the hair to 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.Moreover, to overcome the difference in depression between the outward and return, we can predict the two pull-son at different heights by placing them on an inclined plane. This makes it possible to have a positioning of the pull-threads adapted to the great majority of the commercial carpets on which the depression of the nozzle is not constant: on a rather dense or looped carpet, the depression is less important than on a carpet tufted 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.Furthermore, the suction zone at the front can in some cases where the pull-son 24 would not succeed in hanging the fibers and / or would release a packet of fibers, to be able to suck and avoid leaving this waste on the ground.
