Description

Il existe déjà des appareils portatifs qui permettent de fabriquer des tissus de fil ou de laine de façon artisanale par des moyens simplifiés. La plupart de ces appareils comporte deux nappes d'aiguilles, inbriquées l'une dans l'autre et susceptibles de s'écarter l'une de l'autre soit par flexion hors du plan commun des deux nappes, soit par translation perpendiculairement à ce plan. Les brevets suivants D 547 795, US 2 096 659, US 2 166 688 et 2 307 069 décrivent des appareils de ce genre. Un appareil d'un autre type est décrit dans le brevet F 2 278 811 (No de publication 74 13 621). Les deux nappes d'aiguilles sont ici montées de façon à pouvoir subir un déplacement relatif en translation dans le sens des aiguilles, de sorte qu'elles restent constamment dans le même plan. Les aiguilles des deux nappes sont pourvues de crochets à une de leurs extrémités et d'un chas à leur autre extrémité.There are already portable devices which make it possible to fabricate yarn or wool fabrics by hand using simplified means. Most of these devices have two plies of needles, nested one inside the other and capable of deviating from one another either by bending out of the common plane of the two plies, or by translation perpendicular to it. plan. The following patents D 547 795, US 2 096 659, US 2 166 688 and 2 307 069 describe devices of this kind. An apparatus of another type is described in patent F 2,278,811 (Publication No. 74 13 621). The two plies of needles are here mounted so as to be able to undergo a relative displacement in translation in the direction of the needles, so that they remain constantly in the same plane. The needles of the two tablecloths are provided with hooks at one of their ends and with an eye at their other end.

En général, ces appareils connus permettent de réaliser des pièces de tissu de dimensions supérieures à celles de l'appareil lui-même à condition de procéder par tronçons successifs et de relier les tronçons les uns aux autres de façon convenable.In general, these known devices make it possible to produce pieces of fabric of dimensions larger than those of the device itself, provided that it proceeds in successive sections and that the sections are connected to one another in a suitable manner.

Certains de ces appareils sont portatifs, de sorte qu'ils doivent être constamment tenus dans une main pendant que l'utilisateur travaille avec l'autre main ; d'autres comportent un socle conçu de façon à être fixé sur un support. Ils sont alors relativement encombrants.Some of these devices are portable, so they must be constantly held in one hand while the user is working with the other hand; others have a base designed to be fixed on a support. They are then relatively bulky.

L'objet de la présente invention est un appareil du type connu par le dernier brevet français mentionné ci-dessus, c'est-à-dire un appareil à tisser à main, du type comprenant deux nappes d'aiguilles parallèles imbriquées l'une dans l'autre, et des moyens pour provoquer un déplacement relatif et alternatif des deux nappes dans le sens longitudinal des aiguilles, de manière à permettre le dépôt d'un fil de trame alternativement sur les extrémités des aiguilles de chaque nappe.The object of the present invention is an apparatus of the type known by the last French patent mentioned above, that is to say a hand weaving apparatus, of the type comprising two layers of nested parallel needles, one in the other, and means for causing a relative and alternating displacement of the two plies in the longitudinal direction of the needles, so as to allow the deposition of a weft thread alternately on the ends of the needles of each ply.

Son but est de fournir un appareil léger mais d'une utilisation plus pratique que les appareils connus et permettant de réaliser des tissus de grandes dimensions par emploi simultané de plusieurs appareils accouplés les uns aux autres.Its purpose is to provide a light device but of a more practical use than the known devices and allowing to realize fabrics of large dimensions by simultaneous use of several devices coupled to each other.

Dans ce but, l'appareil selon l'invention, du genre mentionné ci-dessus, est caractérisé en ce qu'il comprend un bâti rigide auquel est lié un support coulissant mobile dans le sens des aiguilles, en ce que les aiguilles sont supportées et guidées, d'une part, par le bâti, et d'autre part, par le support coulissant, et en ce que les aiguilles d'une nappe sont fixes par rapport au bâti, tandis que celles de l'autre nappe sont liées par groupes à des organes d'entraînement mobiles en va-et-vient par rapport au bâti, le support coulissant et les organes d'entraînement étant démontables de manière à libérer les aiguilles et permettre le soulèvement de l'ensemble des deux nappes.For this purpose, the apparatus according to the invention, of the kind mentioned above, is characterized in that it comprises a rigid frame to which is linked a sliding support movable in the direction of the needles, in that the needles are supported and guided, on the one hand, by the frame, and on the other hand, by the sliding support, and in that the needles of one ply are fixed relative to the frame, while those of the other ply are linked in groups with movable drive members back and forth relative to the frame, the sliding support and the drive members being removable so as to release the needles and allow the lifting of the assembly of the two plies.

On va décrire ci-après, à titre d'exemple, une forme d'exécution de l'appareil à tisser selon l'invention, en se référant au dessin annexé dont :

  • la fig. 1 est une vue en perspective schématique et simplifiée,
  • la fig. 2 une vue en plan de dessus partielle,
  • la fig. 3 une vue en coupe selon la ligne III-III de la fig. 2, et
  • la fig. 4 une vue en élévation depuis l'arrière.
An embodiment of the weaving apparatus according to the invention will be described below, by way of example, with reference to the attached drawing, in which:
  • fig. 1 is a schematic and simplified perspective view,
  • fig. 2 a partial plan view from above,
  • fig. 3 a sectional view along line III-III of FIG. 2, and
  • fig. 4 an elevational view from the rear.

A la fig. 1, on voit les éléments principaux de l'appareil à tisser qui constitue une forme d'exécution de l'invention. La plus grande partie des pièces de cet appareil peut être réalisée en matière plastique, donc par des opérations de moulage.In fig. 1, we can see the main elements of the weaving device which constitutes an embodiment of the invention. Most of the parts of this device can be made of plastic, therefore by molding operations.

L'appareil comporte deux nappes d'aiguilles 1 qui sont disposées parallèlement les unes aux autres dans un même plan, et qui sont destinées à recevoir le fil de trame. Ces aiguilles sont portées, d'une part, vers l'avant par un support coulissant 2, et d'autre part, à leur extrémité arrière par la traverse postérieure 3 du bâti de l'appareil qui est désigné de façon générale par 4. Le bâti comporte, outre la traverse postérieure 3, une traverse antérieure 5 et deux longerons parallèles 6. Ces derniers seront, de préférence, de.section circulaire et réalisés en-aluminium, leurs extrémités étant moulées dans les traverses antérieures et postérieures. Le bâti prend ainsi la forme d'un cadre rectangulaire rigide. Les traverses 3 et 5 sont destinées à reposer sur une table ou tout autre surface plane. Le bâti peut aussi reposer, par exemple, sur les genoux de l'utilisateur. Aux extrémités des traverses sont prévus des éléments de liaison formés, par exemple par des tenons latéraux 7 et des logements 8. Les logements sont agencés de façon à recevoir les tenons latéraux d'un autre bâti qui serait disposé parallèlement à celui qui est représenté au dessin. Par introduction de chevilles dans des trous correspondants que présentent les tenons latéraux, on réalise l'assemblage de plusieurs bâtis côte à côte, ce qui permet de réaliser un tissage ayant une largeur aussi grande qu'on le désire.The apparatus comprises two plies of needles 1 which are arranged parallel to one another in the same plane, and which are intended to receive the weft thread. These needles are carried, on the one hand, towards the front by a sliding support 2, and on the other hand, at their rear end by the rear cross-member 3 of the frame of the apparatus which is generally designated by 4. The frame comprises, in addition to the rear cross member 3, a front cross member 5 and two parallel beams 6. The latter will preferably be circular de.section and made of aluminum, their ends being molded in the front and rear cross members. The frame thus takes the form of a rigid rectangular frame. The crosspieces 3 and 5 are intended to rest on a table or any other flat surface. The frame can also rest, for example, on the user's knees. At the ends of the sleepers are provided connecting elements formed, for example by lateral studs 7 and housings 8. The housings are arranged so as to receive the lateral studs of another frame which would be arranged parallel to that which is shown in drawing. By introducing pegs into corresponding holes that have the lateral tenons, we realize the assembly of several frames side by side, which allows for a weaving having a width as large as desired.

Le support coulissant 2 comporte une traverse inférieure 9 qui est équipée de coulisseaux tubulaires 10 engagés sur les longerons 6. Dans son bord supérieur, la traverse 9 présente une série d'encoches parallèles (9a) (fig. 3) à profil en arc de cercle dans lesquelles passent les aiguilles 1. Ces aiguilles sont tenues en place par une traverse supérieure 11 qui se fixe de façon amovible sur la traverse 9 par des moyens qui seront décrits plus en détail en référence à la fig. 3. L'ensemble 2 peut être déplacé à la main le long des longerons 6 au fur et à mesure de l'avancement du travail comme on le verra plus loin. Bien qu'il supporte les aiguiles à leur extrémité antérieure, celles-ci ne sont pas rigidement fixées au support coulissant, qui se déplace sans les entraîner.The sliding support 2 comprises a lower cross member 9 which is fitted with tubular slides 10 engaged on the side members 6. In its upper edge, the cross member 9 has a series of parallel notches (9a) (fig. 3) with an arcuate profile. circle in which pass needles 1. These needles are held in place by an upper cross member 11 which is removably fixed to the cross member 9 by means which will be described in more detail with reference to FIG. 3. The assembly 2 can be moved by hand along the side members 6 as the work progresses as will be seen below. Although it supports the needles at their anterior end, these are not rigidly fixed to the sliding support, which moves without entraining them.

Les aiguilles 1 sont en anticorodal étiré et élexé, de section circulaire. Leur extrémité antérieure est recourbée vers le haut de manière à accrocher le fil de trame et leur extrémité arrière porte un embout 34 en forme de chas. Ce dernier sera par exemple en matière plastique. Chaque aiguille présente une partie amincie la (fig. 2) limitée par deux méplats au voisinage du chas 34.The needles 1 are in stretched and elexed anticorodal, of circular section. Their front end is curved upwards so as to hang the weft thread and their rear end carries an end piece 34 in the shape of an eye. The latter will for example be made of plastic. Each needle has a thinned part 1a (fig. 2) limited by two flats in the vicinity of the eye 34.

L'extrémité postérieure du bâti 4, c'est-à-dire la traverse 3, est agencée de façon que la moitié des aiguilles soit fixe par rapport au bâti, tandis que l'autre moitié est mobile longitudinalement en va-et-vient entre deux positions extrêmes prédéterminées. Pour cela, la traverse 3 présente une série d'encoches rectangulaires 3a dans lesquelles s'engagent les méplats des aiguilles. Pour une nappe d'aiguilles constituant la nappe fixe, les méplats la ont une longueur égale à l'épaisseur de la traverse, de sorte que les aiguilles sont ainsi retenues longitudinalement en place.The rear end of the frame 4, that is to say the cross member 3, is arranged so that half of the needles are fixed relative to the frame, while the other half is movable longitudinally back and forth between two predetermined extreme positions. For this, the crosspiece 3 has a series of rectangular notches 3a in which engage the flats of the needles. For a ply of needles constituting the fixed ply, the flats la have a length equal to the thickness of the cross member, so that the needles are thus retained longitudinally in place.

Pour la seconde nappe, dont les aiguilles sont imbriquées dans celles de la première nappe, le méplat lb est beaucoup plus long que l'épaisseur de la traverse 3.For the second ply, the needles of which are nested in those of the first ply, the flat lb is much longer than the thickness of the cross-member 3.

Une série d'organes d'entraînement 12a, 12b, 12c, 12d, 12e, sont montés côte à côte sur la traverse 3. La disposition exacte et le montage des différents organes 12 sont visibles aux fig. 2 et 3. Tous les organes 12 étant pareils, seul un d'entre eux est représenté. Il comporte principalement une plaque rectangulaire 13 munie sur sa face supérieure d'un plot 14 faisant office.de poignée. La plaque 13 présente deux fentes longitudinales parallèles 15 et à l'avant et à l'arrière, des parois transversales 16, 17 munies d'échancrures ayant la forme visible à la fig. 4. Comme on le voit à cette figure, chaque paroi 16 ou 17 comporte deux échancrures en demi-cercle 18, 19, une échancrure en quart de cercle 20 et trois fentes rectangulaires 21, 22, 23 disposées respectivement à l'opposé de l'échancrure en quart de cercle 20 entre les échancrures en demi-cercle 18 et 19 et entre les échancrures 19 et 20. D'autre part, immédiatement en retrait de la paroi arrière 17, la plaque 13 présente une fente transversale dans laquelle,sont engagés les deux pieds 24 et 25 d'un organe d'arrêt 26 qui comporte un rebord postérieur 27 (fig. 2). Les pieds 24 et 25 sont munis de becs latéraux (fig. 4) qui bloquent l'organe 26 par rapport à la plaque 13 tout en lui permettant de se déplacer verticalement sur une certaine distance par rapport à elle.A series of drive members 12a, 12b, 12c, 12d, 12e, are mounted side by side on the cross-member 3. The exact arrangement and the mounting of the various members 12 are visible in FIGS. 2 and 3. All the members 12 being the same, only one of them is shown. He com mainly carries a rectangular plate 13 provided on its upper face with a stud 14 acting as a handle. The plate 13 has two parallel longitudinal slots 15 and at the front and at the rear, transverse walls 16, 17 provided with notches having the shape visible in FIG. 4. As can be seen in this figure, each wall 16 or 17 has two semicircle notches 18, 19, a quarter circle notch 20 and three rectangular slots 21, 22, 23 respectively arranged opposite the 'notch in a quarter circle 20 between the semicircle notches 18 and 19 and between the notches 19 and 20. On the other hand, immediately set back from the rear wall 17, the plate 13 has a transverse slot in which are engaged the two feet 24 and 25 of a stop member 26 which has a rear flange 27 (fig. 2). The feet 24 and 25 are provided with lateral spouts (fig. 4) which block the member 26 relative to the plate 13 while allowing it to move vertically over a certain distance relative to it.

Les fentes 15 sont profilées et présentent des rebords internes 15a qui s'étendent jusqu'à mi-hauteur de l'épaisseur de la plaque 13. Toutefois, ces rebords sont interrompus à l'extrémité arrière de la fente où celle-ci est de contour circulaire.The slots 15 are profiled and have internal edges 15a which extend up to half the height of the thickness of the plate 13. However, these edges are interrupted at the rear end of the slot where the latter is of circular outline.

Le montage des organes d'entraînement 12 résulte également des fig. 2 et 3. Pour les aiguilles de la nappe mobile, la longueur du méplat lb correspond à la longueur de la plaque 13 des organes d'actionnement 12. Les aiguilles de l'un et de l'autre type étant intercalées, on voit que les aiguilles fixes dont le méplat la est de courte longueur seront engagées dans les échancrures en demi-cercle ou en quart de cercle 18, 19 ou 20 de l'organe d'actionnement, tandis que les autres aiguilles seront solidarisées des organes d'entraînement puisque leur méplat sera engagé dans les fentes 21, 22 ou 23. Normalement les organes d'entraînement 12 se trouveront placés, comme le montrent les fig. 2 et 3. Les butées 26 maintiennent les parois arrière 17 à une certaine distance de la traverse 3, de sorte que les vis 28 fixées dans le sommet de la traverse 3 sont engagées par leur tête au-dessus des rebords 15a. L'organe d'entraînement 12 peut coulisser à partir de la position des fig. 2 et 3 vers l'arrière. 11 entraîne alors les trois aiguilles de la nappe mobile qui lui sont assujetties. Ces aiguilles étant plus longues que les aiguilles de la nappe fixe, leurs extrémités recourbées viennent se placer en arrière de la des extrémités des aiguilles fixes, alors que dans la position représentée au dessin, elles se trouvent en avant de cette ligne d'extrémité.The mounting of the drive members 12 also results from FIGS. 2 and 3. For the needles of the movable ply, the length of the flat lb corresponds to the length of the plate 13 of the actuating members 12. The needles of one and the other type being interposed, it can be seen that the fixed needles, the flat length of which is short, will be engaged in the semi-circular or quarter-circular indentations 18, 19 or 20 of the actuating member, while the other needles will be secured to the driving members since their flat will be engaged in slots 21, 22 or 23. Normally the drive members 12 will be placed, as shown in FIGS. 2 and 3. The stops 26 maintain the rear walls 17 at a certain distance from the cross-member 3, so that the screws 28 fixed in the top of the cross-member 3 are engaged by their heads above the flanges 15a. The drive member 12 can slide from the position of FIGS. 2 and 3 backwards. 11 then drives the three needles of the movable ply which are subject to it. These needles being longer than the needles of the fixed ply, their curved ends are placed behind the end of the fixed needles, while in the position shown in the drawing, they are located in front of this end line.

Les aiguilles mobiles entraînées par les organes 12 coulissent dans les échancrures 9a de la traverse 9 du support coulissant 2 et effectuent un mouvement de va-et-vient commandé par les organes 12.The movable needles driven by the members 12 slide in the notches 9a of the cross member 9 of the sliding support 2 and perform a reciprocating movement controlled by the members 12.

Ce déplacement permet de réaliser le tissage selon le principe connu par le brevet mentionné au début. Lorsque les pointes des aiguilles de la nappe mobile se trouvent en avant des pointes des aiguilles de la nappe fixe, on dépose le fil de trame de façon qu'il repose sur les extrémités des aiguilles mobiles. Lorsqu'on retire les aiguilles mobiles vers l'arrière, le fil est tiré par leurs crochets et s'engage sous les aiguilles fixes. On peut alors déposer un second passage du fil de trame sur les extrémités des aiguilles fixes puis repousser les aiguilles mobiles vers l'avant. Elles passent alors sur le fil de trame et on peut recommencer l'opération. Les aiguilles se chargent progressivement d'un entrelacement de fils de trame et au fur et à mesure que ce dernier s'allonge, le support coulissant est repoussé vers l'arrière.This movement makes it possible to weave according to the principle known by the patent mentioned at the start. When the tips of the needles of the movable ply are in front of the tips of the needles of the fixed ply, the weft thread is deposited so that it rests on the ends of the movable needles. When the movable needles are withdrawn backwards, the thread is pulled by their hooks and engages under the fixed needles. We can then deposit a second passage of the weft thread on the ends of the fixed needles and then push the movable needles forward. They then pass over the weft thread and we can start the operation again. The needles are gradually loaded with an interlacing of weft threads and as the latter lengthens, the sliding support is pushed backwards.

Pour effectuer la seconde opération consistant dans le passage des fils de chaîne, il est nécessaire de dégager les deux nappes d'aiguilles. Pour cela, on commence par enlever les organes d'entraînement 12. Les éléments d'arrêt 26 sont soulevés grâce au rebord 27, ce qui.permet de faire avancer légèrement chaque organe 12 vers l'avant (fig. 3), les pieds 24 et 25 de la butée 26 pouvant s'engager sur le biais 29 ménagé à la partie supérieure arrière de la traverse 3. Les têtes des vis 28 se trouvent alors dans la partie circulaire arrière des fentes 15 (fig. 2), de sorte que les organes d'entraînement 12 peuvent être dégagés facilement. Pour dégager la traverse supérieure 11 du support coulissant, il suffit de faire glisser latéralement les étriers 30 montés sur cette traverse, ce qui dégage l'ouverture des deux trous borgnes 31 ménagés dans sa face inférieure. Les tenons 32 montés dans la face supérieure de la traverse inférieure 9 sont alors dégagés, ce qui permet l'élimination de la traverse 11. L'ensemble des aiguilles sur lesquelles est monté l'entrelacement des fils de trame peut alors être soulevé et reporté à l'arrière du peigne 33 qui constitue un organe auxiliaire de l'appareil décrit. Les fils de chaîne seront attachés au chas 34 formé à l'extrémité arrière des aiguilles 1, et celles-ci seront tirées à travers l'entrelacement des fils de trame, ce qui mettra les fils de chaîne en place. Chaque aiguille 1 sera alors successivement replacée sur le bâti 4 après que l'on aura ramené le support coulissant 2 vers l'avant. La traverse supérieure 11 du support coulissant 2 et les organes d'entraînement 12 seront ensuite remis en place, ce qui permettra de continuer la pose du fil de trame.To carry out the second operation consisting in the passage of the warp threads, it is necessary to release the two layers of needles. For that, we start by removing the drive members 12. The stop elements 26 are raised by means of the rim 27, which makes it possible to slightly advance each member 12 forwards (fig. 3), the feet 24 and 25 of the stop 26 which can engage on the bias 29 formed at the rear upper part of the cross member 3. The heads of the screws 28 are then located in the rear circular part of the slots 15 (FIG. 2), so that the 12 drive can be cleared easily. To release the upper cross member 11 from the sliding support, it suffices to slide the stirrups 30 mounted on this cross member laterally, which releases the opening of the two blind holes 31 formed in its lower face. The pins 32 mounted in the upper face of the lower cross 9 are then released, which allows the elimination of the cross 11. The set of needles on which is mounted the interlacing of the weft son can then be lifted and transferred behind the comb 33 which constitutes an auxiliary member of the device described. The warp threads will be attached to the eye 34 formed at the rear end of the needles 1, and these will be pulled through the interlacing of the weft threads, which will put the warp threads in place. Each needle 1 will then be successively replaced on the frame 4 after the sliding support 2 has been brought forward. The upper cross member 11 of the sliding support 2 and the drive members 12 will then be replaced, which will allow the laying of the weft thread to continue.

En prévoyant des aiguilles en métal léger d'un diamètre de l'ordre de 4 mm par exemple, espacées les unes des autres d'environ 9 mm, on peut réaliser des tissus en grosse laine pouvant servir de couvertures, de fourres de coussins, etc.By providing light metal needles with a diameter of the order of 4 mm for example, spaced from each other by about 9 mm, it is possible to produce coarse wool fabrics which can serve as blankets, cushion covers, etc.

Dans une forme d'exécution préférée, les deux aiguilles extérieures qui appartiennent, l'une à la nappe fixe et l'autre à la nappe mobile, présentent à leur extrémité antérieure un léger décrochement vers l'extérieur, afin de répondre à la légère tension du fil de trame. Toutefois, dans le cas où l'on prévoit d'accoler plusieurs appareils tels que décrits ci-dessus, pour constituer un assemblage de grande largeur, les aiguilles qui se trouvent à la limite entre deux bâtis devraient être remplacées par des aiguilles rectilignes comme les aiguilles normales. Toutefois, il est bien.évident que l'appareil décrit peut egalement être construit dans d'autres dimensions et dans d'autres matériaux, par exemple avec des aiguilles plus fines espacées par exemple de quelques millimètres seulement.In a preferred embodiment, the two outer needles which belong, one to the fixed ply and the other to the movable ply, have at their end anterior slight offset to the outside, in order to respond to the slight tension of the weft thread. However, in the case where it is planned to attach several devices as described above, to constitute an assembly of large width, the needles which are at the limit between two frames should be replaced by straight needles like the normal needles. However, it is obvious that the apparatus described can also be constructed in other dimensions and in other materials, for example with finer needles spaced apart, for example, by only a few millimeters.
