Abstract

A holder for a bobbin for releasing yarn to e.g. a weaving machine is fitted with a replaceable liner made of woven wire mesh to provide a porous surface with high points pref. about 1.5 mm apart against which the flying yarn can brush as it leaves the holder. The tubular liner may be fabricated from flat metallic cloth by conversion to a cylindrical form with a longitudinal seam to join the ends of a panel corresponding in length to the circumference of the liner.

Description

La présente invention concerne un dispositif permettant de limiter le ballon que forme un fil, par exemple lors des opérations de dévidage, de moulinage ou de retordage, auxquelles ce fil peut être soumis lors de sa fabrication.The present invention relates to a device making it possible to limit the balloon formed by a thread, for example during the unwinding, milling or twisting operations, to which this thread can be subjected during its manufacture.

La demande de brevet français n° 76/20 540 publiée sous le n° 2 356 450 décrit un procédé pour limiter le ballon d'un fil lors d'une opération de dévidage ou de renvidage à laquelle ce fil est soumis lors des différentes étapes de sa fabrication, ledit procédé étant caractérisé par le fait que le fil est mis en contact ponctuel avec une succession d'arêtes espacées, parallèles les unes aux autres, disposées sur une surface de révolution cylindrique engendrée par une génératrice parallèle à l'axe de défilement du fil.French patent application No. 76/20 540 published under No. 2,356,450 describes a method for limiting the balloon of a thread during a reeling or reeling operation to which this thread is subjected during the various stages of its manufacture, said method being characterized in that the wire is brought into punctual contact with a succession of spaced edges, parallel to each other, arranged on a surface of cylindrical revolution generated by a generator parallel to the axis of thread scrolling.

Ce document décrit divers dispositifs permettant la mise en oeuvre dudit procédé.This document describes various devices allowing the implementation of said method.

La demande de certificat d'addition au brevet précité, demande n° 77/04 630 publiée sous le n° 2 380 360 décrit une solution qui, par rapport aux enseignements du FR-A-76/20 540 précité, présente l'avantage de réduire d'une manière importante le bruit produit lors du dévidage ou du renvidage du fil.The request for certificate of addition to the aforementioned patent, request n ° 77/04 630 published under n ° 2 380 360 describes a solution which, compared to the teachings of FR-A-76/20 540 mentioned above, has the advantage to significantly reduce the noise produced during the unwinding or rewinding of the wire.

Selon ce document, le dispositif limitateur de ballon est constitué par un élément cylindrique dont la surface interne comporte une série d'arêtes espacées, parallèles les unes aux autres, contre lesquelles le fil vient en contact ponctuel lors de son déplacement, ce dispositif se caractérisant par le fait que la surface comportant les arêtes est amortie par une couche de matière possédant un très bon coefficient d'absorption des bruits.According to this document, the balloon limiting device is constituted by a cylindrical element whose internal surface comprises a series of spaced edges, parallel to each other, against which the wire comes into punctual contact during its movement, this device being characterized by the fact that the surface comprising the edges is damped by a layer of material having a very good noise absorption coefficient.

Cette solution donne de très bons résultats tant en ce qui concerne les caractéristiques textiles de la matière traitée qu'en ce qui concerne la diminution du niveau sonore de l'installation lors de son fonctionnement.This solution gives very good results both as regards the textile characteristics of the material treated as with regard to the reduction in the sound level of the installation during its operation.

Elle présente cependant comme inconvénient d'être de conception relativement complexe, donc d'un prix de revient élevé. De plus, il est évident que les frottements entràînent une usure des arêtes et qu'il.est donc nécessaire à intervalles de temps réguliers de rénover ou de changer le pot. Dans les deux cas, le coût de l'opération est élevé et le matériel peut éventuellement être immobilisé pendant une durée assez longue entraînant des pertes de production.However, it has the disadvantage of being of relatively complex design, therefore of a high cost price. In addition, it is obvious that the friction causes wear on the edges and that it is therefore necessary at regular time intervals to renovate or change the pot. In both cases, the cost of the operation is high and the equipment can possibly be immobilized for a fairly long period, leading to production losses.

Or on a trouvé et c'est ce qui fait l'objet de la présente invention, un dispositif limitateur de ballon de conception simple, facile à entretenir et qui permet par ailleurs de conserver les qualités (faible niveau de bruits et non détérioration des propriétés du fil) des brise-ballons faisant l'objet des documents précités.Now, and this is what is the subject of the present invention, a balloon limiting device of simple design, easy to maintain and which moreover makes it possible to maintain the qualities (low level of noise and non deterioration of the properties wire) of balloon breakers which are the subject of the aforementioned documents.

D'une manière générale, l'invention concerne donc un dispositif limitateur du ballon que forme un fil lors des opérations auxquelles ce fil est soumis pour sa fabrication, et cedit dispositif étant constitué par un élément cylindrique dont la surface interne présente des parties en relief et en creux telles que le fil vienne en contact ponctuel lors de son déplacement et se caractérise par le fait que ladite surface contrelaquelle le ballon du fil vient en contact est constituée par un manchon disposé à l'intérieur du pot proprement dit, ce manchon étant à base d'une structure maillée.In general, the invention therefore relates to a device limiting the balloon formed by a wire during the operations to which this wire is subjected for its manufacture, and said device being constituted by a cylindrical element whose internal surface has parts in relief. and in the hollow such that the wire comes into punctual contact during its displacement and is characterized by the fact that said surface co nt r elaquelle the balloon of the wire comes into contact is constituted by a sleeve disposed inside the pot itself, this sleeve being based on a mesh structure.

Selon une forme préférentielle de réalisation conforme à l'invention, le manchon interne sous forme de structure maillée est constitué par un tissu métallique. Les mailles de ce tissu métallique (c'est-à-dire l'ouverture comprise entre deux fils de chaîne et deux fils de trame consécutifs) auront une dimension de l'ordre du millimètre. De plus, les fils métalliques constituant ce tissu maillé seront, par exemple des fils d'acier ayant un diamètre d'environ 0,5 millimètre.According to a preferred embodiment in accordance with the invention, the internal sleeve in the form of a mesh structure consists of a metallic fabric. The meshes of this metallic fabric (i.e. the opening between two warp threads and two consecutive frame) will have a dimension of the order of a millimeter. In addition, the metal wires constituting this mesh fabric will be, for example steel wires having a diameter of about 0.5 millimeter.

Le manchon conforme à l'invention sera obtenu par découpe dans un tissu de grande longueur et largeur, les bords de ce tissu pouvant être solidarisés l'un avec l'autre après mise sous forme cylindrique. Selon une forme préférentielle de réalisation, après découpe du tissu à une largeur correspondant à la hauteur du manchon à réaliser et à une longueur supérieure à la longueur développée du manchon, les bords destinés à être réunis seront simplement retournés sur eux-mêmes, en sens inverse l'un de l'autre. Selon ce mode de réalisation, le manchon après mise en place à l'intérieur du pot tend à plaquer par lui-même contre les parois de ce dernier, ce qui permet d'envisager l'élimination de tout moyen de fixation additionnel. Cependant, par mesure de sécurité, des vis de fixation peuvent être utilisées.The sleeve according to the invention will be obtained by cutting from a fabric of great length and width, the edges of this fabric being able to be joined to one another after being placed in cylindrical form. According to a preferred embodiment, after cutting the fabric to a width corresponding to the height of the sleeve to be produced and to a length greater than the developed length of the sleeve, the edges intended to be joined together will simply be turned over in direction reverse each other. According to this embodiment, the sleeve after positioning inside the pot tends to press by itself against the walls of the latter, which makes it possible to envisage the elimination of any additional fixing means. However, for safety reasons, fixing screws can be used.

L'invention et les avantages qu'elle apporte seront cependant mieux compris grâce aux exemples de réalisation donnés ci-après à titre indicatif mais non limitatif et qui sont illustrés par les schémas annexés dans lesquels :

  • - la figure 1 illustre schématiquement, en perspective, un élément brise ballon conforme à l'invention disposé à l'intérieur d'un pot, cet élément étant représenté en coupe ;
  • - la figure 2 est une vue de dessus du brise ballon représenté à la figure 1 ;
  • - la figure 3 illustre l'élément de base permettant la réalisation d'un manchon conforme à l'invention ;
  • - la figure 4 est une vue de détail montrant la manière dont est réalisé le manchon conforme à l'invention.
The invention and the advantages which it brings will however be better understood thanks to the exemplary embodiments given below by way of indication but not limitation and which are illustrated by the appended diagrams in which:
  • - Figure 1 schematically illustrates, in perspective, a balloon breaker element according to the invention arranged inside a pot, this element being shown in section;
  • - Figure 2 is a top view of the balloon breaker shown in Figure 1;
  • - Figure 3 illustrates the basic element allowing the production of a sleeve according to the invention;
  • - Figure 4 is a detail view showing how the sleeve is made according to the invention.

Si l'on se reporte aux schémas annexés, et plus particulièrement aux figures 1 et 2, le pot brise-ballon conforme à l'invention est constitué essentiellement par un pot (1), de type connu, à l'intérieur duquel est disposée, coaxialement la bobine (2) de fil. Le fil (3) est dévidé de cette bobine en formant le ballon (4) qui, lors de sa rotation, est en contact ponctuel avec l'intérieur du pot (1). Afin de limiter les bruits et favoriser un bon défilement du fil sans le détériorer, a'l'intérieur du pot (1) est disposé un manchon (5) qui présente une succession de parties en creux et en relief permettant un contact ponctuel du ballon (4).If we refer to the attached diagrams, and more particularly in Figures 1 and 2, the ball-breaking pot according to the invention consists essentially of a pot (1), of known type, inside which is coaxially arranged the coil (2) of wire. The wire (3) is unwound from this coil forming the balloon (4) which, during its rotation, is in point contact with the inside of the pot (1). In order to limit the noises and favor a good running of the wire without damaging it, inside the pot (1) is placed a sleeve (5) which has a succession of hollow and raised parts allowing a punctual contact of the balloon (4).

Ce manchon (5) est, conformément à l'invention, constitué par une structure maillée dont une forme de réalisation est illustrée à la figure 3. Cette structure maillée est obtenue par tissage. Dans le cas présent, on utilise un tissu métallique a base de fils d'acier ayant un diamètre de0,5 millimètre, les fils de trame (6) et de chaîne (7) ayant une densité telle que l'on obtienne des jours (8) d'environ 1,5 millimètre de côté.This sleeve (5) is, in accordance with the invention, constituted by a mesh structure, an embodiment of which is illustrated in FIG. 3. This mesh structure is obtained by weaving. In the present case, a metallic fabric based on steel wires having a diameter of 0.5 millimeters is used, the weft (6) and warp (7) wires having a density such that days are obtained ( 8) about 1.5 millimeters per side.

Le tissu est découpé en panneaux élémentaires dont la longueur et la largeur est telle qu'il puisse être mis sous la forme d'un cylindre dont le diamètre correspond au diamètre interne du pot (1). Il peut être envisagé de découper le tissu à une longueur L correspondant à la circonférence du manchon réalisé, les bords (10,11) étant alors solidarisés, par exemple par soudure. Il est cependant préférable, ainsi que cela ressort de la figure 4, de découper une longueur L légèrement supérieure. De cette manière, les bords (10,11) peuvent être repliés l'un contre l'autre (voir figure 4). On obtient donc dans cette zone la juxtaposition des deux bords (10,11) des contraintes qui tendent non seulement à faire plaquer le manchon contre l'intérieur du pot (1) mais également à lui faire jouer un rôle d'amortisseur. Eventuellement, des vis de fixation (non représentées) sont prévues pour solidariser le manchon (5) réalisé avec le pot (1).The fabric is cut into elementary panels whose length and width is such that it can be put in the form of a cylinder whose diameter corresponds to the internal diameter of the pot (1). It can be envisaged to cut the fabric to a length L corresponding to the circumference of the sleeve produced, the edges (10, 11) then being joined, for example by welding. It is however preferable, as is apparent from FIG. 4, to cut a length L slightly greater. In this way, the edges (10,11) can be folded against each other (see Figure 4). One thus obtains in this zone the juxtaposition of the two edges (10,11) of the stresses which tend not only to make press the sleeve against the interior of the pot (1) but also to make him play a role of shock absorber. Optionally, fixing screws (not shown) are provided to secure the sleeve (5) produced with the pot (1).

Un tel dispositif de conception particulièrement simple permet non seulement d'obtenir une réduction importante du bruit de fonctionnement mais également niben- traîne aucune détérioration de la matière traitée.Such a device of particularly simple design makes it possible not only to obtain a significant reduction in operating noise but also to prevent any deterioration of the material treated.

Il est évident que la présente invention n'est pas limitée à l'exemple de réalisation décrit précédemment mais elle en couvre également toutes les variantes réalisées dans le même esprit.It is obvious that the present invention is not limited to the embodiment described above but it also covers all the variants produced in the same spirit.

Ainsi, si le manchon est de préférence réalisé à partir d'un tissu métallique en forme de treillis, il pourrait être envisagé d'utiliser toute structure équivalente.Thus, if the sleeve is preferably made from a metallic fabric in the form of a lattice, it could be envisaged to use any equivalent structure.
