Description

L'invention a trait au secteur industriel concernant la production de balais, brosses et similaires pour le nettoyage d'une maison ou de locaux en général.The invention relates to the industrial sector relating to the production of brooms, brushes and the like for cleaning a house or premises in general.

La production industrielle de ces ustensiles prévoit, selon l'art connu, la présence d'une planchette de support de touffes ou de petites bottes de fibres, naturelles ou synthétiques, sur laquelle peut être emboîté un manche pour l'utilisation manuelle de l'ustensile. Sur ces planchettes, généralement planes, mais selon certaines solutions complètement arquées ou avec leurs extrémités longitudinales arquées ou incurvées, comme représenté par exemple sur les figures 1, et 3, sont ménagés des trous borgnes uniformément répartis sur la surface de la planchette opposée de celle qui porte le logement pour le manche.Industrial production of these utensils provides, according to known art, the presence of a tufts support board or small bundles of fibers, natural or synthetic, on which can be fitted a handle for the manual use of the utensil. On these boards, generally planar, but according to certain completely arched solutions or with their arched or curved longitudinal ends, as shown for example in FIGS. 1, and 3, are blind holes uniformly distributed on the surface of the board opposite that which carries the housing for the handle.

Dans ces trous on encastre ensuite des touffes de fibres préalablement formées groupant en un faisceau les fibres choisies de longueur à peu près double par rapport à la longueur X (voir la figure 1) des touffes de fibres qui font saillie de ladite planchette ou balai ainsi obtenu; le faisceau des fibres réunies est replié en U de manière que le coude obtenu facilite l'encastrement des touffes de fibres dans les trous dont la planchette est pourvue. Les opérations de perçage de la planchette et d'encastrement des touffes de fibres dans lesdits trous sont exécutées moyennant le montage de la planchette sur une machine pantographe tridimensionnelle de manière qu'elle peut osciller autour d'un pivot qui se trouve sur un axe passant par le centre de la planchette et disposé du côté de celle-ci destiné à recevoir le manche. On peut ainsi obtenir sur la planchette des trous inclinés, par rapport à la surface de laquelle les touffes de fibres feront saillie, en vue de donner un certain évasement du moins aux touffes de fibres qui se trouvent en correspondance des zones extrêmes longitudinales de la même planchette.In these holes are then embedded tufts of fibers previously formed grouping in a bundle the selected fibers of length roughly double relative to the length X (see Figure 1) tufts of fibers which project from said board or broom as well got; the bundle of combined fibers is folded in a U so that the elbow obtained facilitates the embedding of tufts of fibers in the holes with which the board is provided. The operations of drilling the board and embedding the tufts of fibers in said holes are carried out by mounting the board on a three-dimensional pantograph machine so that it can oscillate around a pivot which is on a passing axis. through the center of the board and arranged on the side of the board intended to receive the handle. One can thus obtain on the board inclined holes, relative to the surface of which the tufts of fibers will protrude, in order to give a certain flare at least to the tufts of fibers which are in correspondence of the longitudinal extreme zones of the same clipboard.

Ce développement en cloche tend à remplir deux fonctions:

  • - la première est celle d'augmenter par rapport à la longueur de la planchette, la longueur utile "L" de contact des fibres sur la surface à nettoyer;
  • - la deuxième est celle de permettre d'atteindre, lors du balayage, les angles et les arêtes entre des parois contiguës sans être gênés par la planchette.
This bell development tends to fulfill two functions:
  • - the first is that of increasing the useful length "L" of contact of the fibers on the surface to be cleaned with respect to the length of the board;
  • - The second is to allow reaching, during scanning, the angles and edges between adjacent walls without being hindered by the board.

Selon l'art connu, en utilisant des planchettes planes (tel que représenté sur la figure 1) dont on a éventuellement chanfreiné les bords des têtes, on peut obtenir un évasement très limité du développement des fibres du fait qu'on ne peut pas causer des oscillations considérables de la planchette pendant les opérations de perçage. Ceci est dû à l'impossibilité de pénétration des forets sur une surface très inclinée par rapport à leur axe et au risque de rupture des mêmes forets à cause de l'excessive contrainte de flexion.According to the prior art, by using flat boards (as shown in FIG. 1), the edges of the heads of which have possibly been chamfered, it is possible to obtain a very limited flaring of the development of the fibers because it cannot cause considerable oscillations of the board during drilling operations. This is due to the impossibility of penetration of the drills on a surface very inclined with respect to their axis and to the risk of rupture of the same drills because of the excessive bending stress.

Il s'ensuit que la distance "D" entre les extrémités des fibres externes (qui ne sont pas en correspondance des têtes de la planchette) et les têtes n'est pas souvent suffisante à faire que la planchette ne gêne pas le balayage des angles ou des arêtes entre des parois contigües d'une pièce.It follows that the distance "D" between the ends of the external fibers (which are not in correspondence of the heads of the board) and the heads is not often sufficient to ensure that the board does not interfere with the scanning of the angles or edges between contiguous walls of a room.

En vue d'améliorer cette situation on a eu recours aux planchettes représentées sur les figures 2 et 3 des dessins annexrés.In order to improve this situation, use was made of the boards shown in Figures 2 and 3 of the accompanying drawings.

Dans ces cas toutefois la longueur utile "L" de contact des fibres sur la surface à nettoyer apparaît réduite du fait que les groupes de touffes de fibres les plus extérieures ont leurs extrémités relevées de la surface d'appui des autres touffes de fibres qui se trouvent à la partie intermédiaire de la planchette. En tout cas en outre, la distance "D"' entre les extrémités des fibres extérieures et les têtes de la planchette est de peu supérieure à la distance "D" de la figure 1 de manière qu'elle n'est pas en mesure de résoudre de manière excellente le problème du balayage des angles entre des parois contigües d'une pièce.In these cases, however, the useful length "L" of contact of the fibers on the surface to be cleaned appears reduced because the groups of outermost tufts of fibers have their ends raised from the bearing surface of the other tufts of fibers which are found in the middle part of the board. In any case, moreover, the distance "D" 'between the ends of the outer fibers and the heads of the board is slightly greater than the distance "D" in FIG. 1 so that it is not able to an excellent solution to the problem of sweeping angles between contiguous walls of a room.

Le demandeur, songeant au mouvement d'oscillation que la planchette normalement reçoit quand elle doit être percée et ensuite pendant l'étape d'encastrement des touffes de soies ou fibres dans les trous ainsi obtenus, a eu l'intuition que si la planchette pouvait être pourvue, au moins dans ses zones proches des têtes (prises en considération en sens longitudinal), d'une série de petites parois inclinées ayant des surfaces planes, concaves et même convexes en mesure de fournir toujours un point normal à l'axe des forets et des moyens d'encastrement des touffes de soies ou fibres dans les trous obtenus, on aurait pu fabriquer, par exemple un balai dont les fibres faisant saillie de la planchette s'évasaient de manière considérable. En outre le demandeur a compris que si l'on encastrait dans les trous ménagés dans ces zones extérieures des touffes de soies ou fibres de longueur plus étendue par rapport à celles plantées dans les trous uniformément répartis sur la partie intermédiaire restante de la planchette, on aurait pu obtenir un balai où, non seulement les fibres avaient un développement qui s'évasait remarquablement, mais les extrémités libres de toutes les touffes de soies ou fibres pouvaient être disposées sur un même plan et il a également compris que la somme de ces deux effets pouvait permettre la création d'un balai en mesure de résoudre de manière optimale les problèmes exposés ci-dessus.The applicant, thinking of the oscillating movement that the board normally receives when it must be pierced and then during the step of embedding tufts of bristles or fibers in the holes thus obtained, had the intuition that if the board could be provided, at least in its areas close to the heads (taken into consideration in the longitudinal direction), with a series of small inclined walls having flat, concave and even convex surfaces capable of always providing a point normal to the axis of the drills and means for embedding tufts of bristles or fibers in the holes obtained, it would have been possible to manufacture, for example a broom, the fibers of which protrude from the board widened considerably. In addition, the applicant has understood that if there were embedded in the holes made in these outer zones tufts of bristles or fibers of longer length compared to those planted in the holes uniformly distributed over the remaining intermediate part of the board, could have obtained a broom where, not only did the fibers have a development which flared remarkably, but the free ends of all the tufts of bristles or fibers could be arranged on the same plane and he also understood that the sum of these two effects could allow the creation of a broom able to optimally solve the problems outlined above.

Suivant ces intuitions le demandeur a mis au point le procédé pour la fabrication de balais, brosses ou similaires, faisant l'objet de la présente invention, caractérisé essentiellement en ce qu'il comporte les étapes suivantes:

  • - créer une planchette de support des touffes ou petites bottes de fibres pourvue, sur sa surface opposée de celle où le manche doit être emboîté et au moins dans les zones proches de ses têtes, d'une série de petites parois inclinées par rapport à cette surface, formant avec celle-ci un angle aigu et dont l'inclinaison va décroissant par rapport à la même surface au fur et à mesure qu'on va de l'extérieur vers la partie intermédiaire de la planchette;
  • - obtenir, sur ces petites parois inclinées, des trous ou logements correspondants de axe normal ou sensiblement normal auxdites petites parois et également obtenir sur la même surface restante de la planchette d'autres trous ou logements uniformément répartis,d'axes normaux, ou légèrement inclinés par rapport à ladite portion restante de la surface de la planchette;
  • - implanter dans tous lesdits trous au moins une touffe ou une petite botte de fibres, introduisant de préférence dans les trous sur lesdites petites parois des touffes ou petites bottes de fibres de longueur supérieure à celle des touffes ou petites bottes de fibres à implanter ou implantées dans les trous obtenus sur la partie intermédiaire de ladite surface de la planchette, de manière que les extrémités de toutes les touffes ou petites bottes de fibres implantées dans la planchette sont disposées dans un même plan.
According to these intuitions, the applicant has perfected the process for the manufacture of brooms, brushes or the like, forming the subject of the present invention, characterized essentially in that it comprises the following stages:
  • - create a support board for tufts or small bundles of fibers provided, on its surface opposite to that where the handle must be fitted and at least in the areas close to its heads, with a series of small inclined walls with respect to this surface, forming an acute angle with it and whose inclination decreases with respect to the same surface as one goes from the outside towards the intermediate part of the board;
  • - Obtain, on these small inclined walls, corresponding holes or housings of axis normal or substantially normal to said small walls and also obtain on the same remaining surface of the board other uniformly distributed holes or housings, of normal axes, or slightly inclined with respect to said remaining portion of the surface of the board;
  • - implant in all said holes at least one tuft or a small bundle of fibers, preferably introducing into the holes on said small walls tufts or small bundles of fibers of length greater than that of the tufts or small bundles of fibers to be implanted or implanted in the holes obtained on the intermediate part of said surface of the board, so that the ends of all tufts or small bundles of fibers implanted in the board are arranged in the same plane.

Selon une forme d'exécution préférée du procédé objet de la présente invention les extrémités libres de toutes les touffes ou petites bottes de fibres implantées dans la planchette sont rasées, dans le but de porter avec plus de précision les extrémités desdites touffes dans un même plan et le rasage est exécuté de manière que ce plan soit parallèle à la surface de la planchette de laquelle les touffes ou petites bottes de fibres font saillie.According to a preferred embodiment of the process which is the subject of the present invention, the free ends of all tufts or small bundles of fibers implanted in the board are shaved, in order to carry the ends of said tufts more precisely in the same plane and the shaving is carried out so that this plane is parallel to the surface of the board from which the tufts or small bundles of fibers protrude.

Selon une variante possible d'exécution, dans le but d'avoir le manche du balai incliné par rapport à la verticale, ce qui, dans certaines situations, facilite son emploi lors de l'usage de la part d'un utilisateur, le rasage est exécuté de manière que ledit plan de disposition des fibres soit incliné par rapport à la surface de laquelle les touffes ou petites bottes de fibres font saillie.According to a possible variant of execution, in order to have the handle of the broom inclined with respect to the vertical, which, in certain situations, facilitates its use when used by a user, shaving is executed so that said fiber layout plane is inclined relative to the surface of which the tufts or small bundles of fibers protrude.

Encore, selon une autre forme préférée d'exécution, l'inclinaison desdites petites parois inclinées est prévue de manière que chacune de celles-ci, vue de côté, soit essentiellement normale à une ligne droite la joignant à un idéal point d'oscillation de la planchette pour les opération de perçage et d'encastrement des touffes ou des petites bottes de fibres, de manière à faciliter le plus possible les opérations de perçage avec la certitude de n'avoir pas de contraintes mécaniques de flexion sur les forets indépendamment de la valeur de l'oscillation de la planchette autour dudit point.Still, according to another preferred embodiment, the inclination of said small inclined walls is provided so that each of these, seen from the side, is essentially normal to a straight line joining it to an ideal point of oscillation of the board for drilling and embedding tufts or small bundles of fibers, so as to facilitate drilling operations as much as possible with the certainty that there are no mechanical bending stresses on the drills regardless of the value of the oscillation of the board around said point.

Les caractéristiques du procédé de la présente invention ainsi que du balai ou de la brosse qui peuvent être obtenus par ce procédé seront illustrées plus en détail ci-après par la description qui suit d'une forme d'exécution envisagée par le demandeur, en se référant aux dessins annexés, dans lesquels:The characteristics of the process of the present invention as well as the broom or the brush which can be obtained by this process will be illustrated in more detail below by the following description of an embodiment envisaged by the applicant, referring to the attached drawings, in which:

- les figures 1, 2 et 3 représentent, comme déjà éclairci plus haut, des formes connues de balais obtenus suivant les techniques traditionnelles;

  • - la figure 4 montre schématiquement et en vue de côté un balai obtenu selon le procédé de la présente invention, représenté partiellement en coupe;
  • - les figures 5 et 8 montrent schématiquement et selon une perspective de côté, deux solutions alternatives d'une planchette obtenue par le procedé de la présente invention;
  • - la figure 6 montre schématiquement un effet de travail particulier qui peut être obtenu par l'utilisation du balai réalisé selon le procédé de la présente invention;
  • - la figure 7 est une vue de côté, schématique, d'un balai obtenu en utilisant une planchette selon une solution alternative par rapport à celle de la figure 4.
- Figures 1, 2 and 3 show, as already clarified above, known forms of brushes obtained according to traditional techniques;
  • - Figure 4 shows schematically and in side view a brush obtained according to the method of the present invention, partially shown in section;
  • - Figures 5 and 8 show schematically and from a side perspective, two alternative solutions of a board obtained by the process of the present invention;
  • - Figure 6 schematically shows a particular working effect which can be obtained by the use of the brush made according to the method of the present invention;
  • FIG. 7 is a schematic side view of a brush obtained using a board according to an alternative solution to that of FIG. 4.

En se référant aux figures 4 et 5, la planchette 1 obtenue selon le procédé de la présente invention est pourvue, dans les zones 1 a proches des têtes 2 de la même planchette, d'une série de petites parois inclinées 3 obtenues sur la surface 4 de la planchette 1 opposée de celle, indiquée en 5, destinée à recevoir par emboîtement, le manche du balai, non représenté sur les figures.Referring to Figures 4 and 5, the board 1 obtained according to the method of the present invention is provided, in the areas 1a close to the heads 2 of the same board, with a series of small inclined walls 3 obtained on the surface 4 of the board 1 opposite that, indicated in 5, intended to receive by interlocking, the handle of the broom, not shown in the figures.

Les petites parois 3 forment avec la surface 4 de la planchette 1 un angle aigu a dont l'ouverture va décroissant au fur et à mesure que les petites parois 3 sont plus proches de la partie intermédiaire de la planchette 1 (et donc de la surface 4), cette partie intermédiaire étant dépourvue de petites parois. A titre d'exemple, l'angle a' indiqué sur la figure 4 et se référant à la petite paroi 31 la plus proche de la partie intermédiaire de la surface 4, a une valeur bien inférieure à l'angle a qui se réfère à la petite paroi 3 la plus extérieure présentée par la planchette 1.The small walls 3 form with the surface 4 of the board 1 an acute angle a whose opening decreases as the small walls 3 are closer to the intermediate part of the board 1 (and therefore to the surface 4), this intermediate part being devoid of small walls. By way of example, the angle a 'indicated in FIG. 4 and referring to the small wall 3 1 closest to the intermediate part of the surface 4, has a value much less than the angle a which refers to the outermost small wall 3 presented by the board 1.

Comme visible sur la figure 5, les petites parois 3 sont obtenues sur la surface 4 en plusieurs rangées indiquées en F - F, - F2, parallèles à la directrice de symétrie longitudinale de la planchette 1, et elles sont disposées sur plusieurs lignes R, - R2 normales à ladite directrice longitudinale.As visible in FIG. 5, the small walls 3 are obtained on the surface 4 in several rows indicated in F - F, - F 2 , parallel to the longitudinal symmetry director of the board 1, and they are arranged on several lines R , - R 2 normal to said longitudinal director.

Si l'on regarde le balai complètement mis en oeuvre, on peut remarquer que par ce moyen on peut obtenir le remplissement optimal de la surface 4; un observateur qui regarde le balai de côté ne voit pratiquement pas de videsparmi les diverses touffes ou petites bottes de fibres formant le balai.If we look at the mop completely implemented, we can notice that by this means we can obtain the optimal filling of the surface 4; an observer who looks at the broom from the side sees practically no voids among the various tufts or small bundles of fibers forming the broom.

Selon une forme d'exécution préférée du procédé objet de l'invention, l'inclinaison des petites parois 3 est déterminée à l'avance de manière que chacune de celles-ci soit sensiblement normale à une droite 6 la joignant à un point idéal 7 d'oscillation de la planchette 1 pour les opérations de perçage et encastrement des touffes ou petites bottes de fibres 8.According to a preferred embodiment of the process which is the subject of the invention, the inclination of the small walls 3 is determined in advance so that each of these is substantially normal to a straight line 6 joining it at an ideal point 7 oscillation of the board 1 for drilling and embedding tufts or small bundles of fibers 8.

Par cette solution on a la possibilité, pendant la phase de perçage de la planchette 1, de diriger vers les forets des portions de surface de la planchette 1 normales ou sensiblement normales aux axes se ces forets qui de ce fait peuvent opérer sans aucun risque de ruptures, ce qui se produit quand ils sont assujettis à flexion; on a donc pour résultat que les touffes ou petites bottes de fibres 8, surtout celles qui se trouvent dans les zones extérieures du balai, ont un développement très évasé, qui favorise de manière remarquable le résultat qui sera illustré par la suite et qui est la conséquence d'une autre caractéristique particulière obtenue par le procédé objet de l'invention.With this solution, it is possible, during the drilling phase of the board 1, to direct the surface portions of the board 1 normal or substantially normal towards the drills. to the axes are these drills which therefore can operate without any risk of ruptures, which occurs when they are subjected to bending; the result is therefore that the tufts or small bundles of fibers 8, especially those which are in the external zones of the broom, have a very flared development, which remarkably promotes the result which will be illustrated below and which is the consequence of another particular characteristic obtained by the process which is the subject of the invention.

Comme déjà mentionné dans le préambule de la présente description, en vue de faciliter les opérations de balayage des arêtes et des angles entre les parois d'une pièce, il est important que les extrémités des touffes ou bottes de fibres qui se trouvent à proximité des têtes 2 de la planchette soient très écartées desdites têtes. Selon la présente invention les touffes ou bottes de fibres 8 destinées à être implantées dans les trous 16 obtenus sur les petites parois 3 sont choisies de longueur différente l'une par rapport à l'autre. On obtient ainsi une distance D Il entre les extrémités les plus extérieures des touffes ou petites bottes de fibres 8 et les têtes 2 de la planchette 1 bien supérieure (à égalité de longueur X des touffes ou petites bottes de fibres utilisées pour la réalisation des balais de type connu, tel que représenté sur les figures 1, 2 et 3) à la distance D, D, indiquée sur lesdites figures 1-2-3, ce qui permet d'atteindre les résultats recherchés par l'invention. Grâce à cet effet on peut avoir, par conséquent, une longueur L' de la surface d'appui du balai sur le plan à nettoyer bien plus élevée que la longueur de la planchette 1, ce qui, avantageusement, permet de disposer d'un ustensile (soit qu'il s'agisse d'un balai ou d'une brosse) d'emploi plus efficace par rapport aux ustensiles analogues de type connu.As already mentioned in the preamble to the present description, in order to facilitate the scanning operations of the edges and angles between the walls of a part, it is important that the ends of the tufts or bundles of fibers which are located near the heads 2 of the board are very far from said heads. According to the present invention the tufts or bundles of fibers 8 intended to be implanted in the holes 16 obtained on the small walls 3 are chosen to be of different length relative to each other. A distance D II is thus obtained between the outermost ends of the tufts or small bundles of fibers 8 and the heads 2 of the board 1 much greater (at equal length X of the tufts or small bundles of fibers used for making the brooms of known type, as shown in FIGS. 1, 2 and 3) at the distance D, D, indicated in said figures 1-2-3, which makes it possible to achieve the results sought by the invention. Thanks to this effect, it is therefore possible to have a length L ′ of the bearing surface of the brush on the plane to be cleaned which is much greater than the length of the board 1, which advantageously makes it possible to have a utensil (whether it is a broom or a brush) of more efficient use compared to similar utensils of known type.

En vue d'obtenir une coplanarité optimale des extrémités des touffes ou petites bottes de fibres utilisées, on peut, en pratique, selon la présente invention employer deux groupes de touffes ou petites bottes de fibres de longueurs différentes (dont les plus courtes sont à implanter dans la partie intermédiaire de la surface 4) et effectuer, pendant la phase finale de réalisation du balai, le rasage des extrémités des touffes ou des fibres plus longues; cette opération offre la possibilité de porter les extrémités de toutes les touffes ou petites bottes de fibres dans un plan parallèle à la surface 4 (ou bien incliné par rapport à celle-ci si l'on désire obtenir un balai ou une brosse qui, quand en appui sur le sol, offre le manche orienté vers l'utilisateur).In order to obtain optimal coplanarity of the ends of the tufts or small bundles of fibers used, it is possible, in practice, according to the present invention to use two groups of tufts or small bundles of fibers of different lengths (the shortest of which are to be implanted in the intermediate part of the surface 4) and, during the final phase of making the broom, shave the ends of the tufts or longer fibers; this operation offers the possibility of carrying the ends of all tufts or small bundles of fibers in a plane parallel to the surface 4 (or else inclined relative to the latter if it is desired to obtain a broom or a brush which, when resting on the ground, offers the user-oriented handle).

En se référant en particulier à la figure 6, on peut remarquer qu'en utilisant le balai réalisé selon la présente invention on peut obtenir un effet sans doute favorable lors du nettoyage des angles ou des arêtes d'une pièce: en éffet si l'on presse le balai contre ces angles ou arêtes on peut obtenir une déformation élastique des touffes ou des fibres 8 les plus extérieures, lesquelles tendent à s'enfoncer de plus en plus dans ces angles ou arêtes, ce qui favorise leur nettoyage.Referring in particular to FIG. 6, it can be noted that by using the broom produced according to the present invention, it is possible to obtain an effect which is undoubtedly favorable when cleaning the angles or edges of a part: in effect if the the brush is pressed against these angles or edges it is possible to obtain an elastic deformation of the outermost tufts or fibers 8, which tend to sink more and more into these angles or edges, which promotes their cleaning.

Pratiquement les petites parois 3 pourront être inclinées également par rapport à une directrice transversale à la surface 4 de la planchette 1 et elles pourront être réparties de manière uniforme ou non uniforme sur les zones 1a et être pourvues d'un ou de plusieurs logements pour l'encastrement des touffes ou petites bottes de fibres 8. En outre, si on le désire même seulement en vue d'atteindre un certain effet esthétique, la planchette 1 pourra avoior les formes et les conformations les plus différentes. Par exemple, comme le montrent les figures 7 et 8, elle pourra avoir, en correspondance des zones 1a proches des têtes 2, les petites parois inclinées 3 dimensionnées de manière à former essentiellement un seul plan incurvé.In practice, the small walls 3 can also be inclined relative to a transverse director on the surface 4 of the board 1 and they can be distributed in a uniform or non-uniform manner over the zones 1a and be provided with one or more housings for the 'embedding tufts or small bundles of fibers 8. In addition, if desired even only in order to achieve a certain aesthetic effect, the board 1 may avoior the most different shapes and conformations. For example, as shown in FIGS. 7 and 8, it may have, in correspondence with the zones 1a close to the heads 2, the small inclined walls 3 dimensioned so as to essentially form a single curved plane.

En outre, les petites parois 3 pourront être inclinées également selon le sens transversal de la planchette 1; dans ce cas les petites parois les plus inclinées seront toujours celles qui se trouvent davantage vers l'extérieur de la planchette 1. En outre les portions 1 a de la planchette pourront être repliées vers le haut ou en tout cas incurvées ou arquées.In addition, the small walls 3 may also be inclined in the transverse direction of the board 1; in this case the smallest most inclined walls will always be those which are more towards the outside of the board 1. In addition, the portions 1a of the board can be folded upwards or in any case curved or arched.

Sur les figures 7 et 8 la planchette 1 peut être pourvue, dans la zone intermédiaire de sa surface inférieure 4 et tel que représenté en traits interrompus sur la figure 7, d'une portion en retrait 9 qui, grâce au fait que les touffes de fibres 8 sont par conséquent plus longues, permet de mieux exploiter les mêmes touffes de fibres 8 et perdre une quantité inférieure de matière lors de leur rasage. Etant donné qu'on peut disposer, du moins dans la zone présentant ladite portion en retrait 9, de touffes de fibres 8 d'une certaine longueur, on obtient un balai pourvu de plus de souplesse et donc d'un effet nettoyant encore amélioré.In FIGS. 7 and 8 the board 1 can be provided, in the intermediate zone of its lower surface 4 and as shown in broken lines in FIG. 7, with a recessed portion 9 which, thanks to the fact that the tufts of fibers 8 are therefore longer, makes it possible to better exploit the same tufts of fibers 8 and lose a smaller amount of material when shaving. Since it is possible to have, at least in the zone having said recessed portion 9, tufts of fibers 8 of a certain length, a brush is obtained which is provided with more flexibility and therefore with a further improved cleaning effect.

Egalement en correspondance de cette zone intermédiaire de la surface 4, les trous 16, et par conséquent les touffes de fibres 8, peuvent être disposés perpendiculairement à la direction longitudinale de la planchette 1, ou bien leurs axes peuvent passer par le point 7 pour une distribution meilleure et plus uniforme des extrémités des fibres.Also in correspondence with this intermediate zone of the surface 4, the holes 16, and consequently the tufts of fibers 8, can be arranged perpendicular to the longitudinal direction of the board 1, or else their axes can pass through the point 7 for a better and more uniform distribution of the fiber ends.

Pratiquement la planchette 1 pourra être obtenue en utilisant n'importe quelle matière appropriée et les petites parois 3 pourront être formées directement pendant la phase de moulage de la planchette 1 (si elle est fabriquée en matière plastique) ou bien obtenues par usinage, par exemple par fraisage; en outre leur surface pourra être plane, ou bien convexe ou bien concave.Practically the board 1 can be obtained using any suitable material and the small walls 3 can be formed directly during the molding phase of the board 1 (if it is made of plastic) or else obtained by machining, for example by milling; furthermore, their surface can be flat, or convex or concave.
