Abstract

The invention concerns woven straps having transverse contractions, as well as a method and apparatus for their manufacture. Contractions are formed along straps having a continuous unchanging weave and continuous selvedge by altering spacing of warp yarns during weaving. The warp yarns are spaced by a V or fan shaped support which is vertically movable to cause corresponding width variations in the straps.

Description

L'invention; concerne des sangles avec localement des rétrécissements transversaux disposés sur des longueurs variables destinés à assurer un positionnement desdites sangles dans un moyen de fixation tel que boucle d'amarrage.The invention; relates to straps with locally transverse constrictions arranged over variable lengths intended to ensure positioning of said straps in a fixing means such as a mooring loop.

Ces sangles sont obtenues sur des métiers navettes, soit au moyen de changement de texture intervenant au droit des rétrécissements, soit en éliminant des fils de chaîne, soit en exerçant un effort de tension sur le fil de trame en vue d'assurer le rapprochement transversal des fils de chaîne, soit encore en utilisant des peignes spéciaux. On peut par exemple citer le brevet FR 1.395 815 qui enseigne la réalisation d'un tissu avec des rétrécissements sur un métier à navettes, notamment pour l'exécution de cravates.These straps are obtained on shuttle looms, either by means of a change in texture occurring at the level of the narrowing, or by eliminating warp threads, or by exerting a tension force on the weft thread in order to ensure transverse approximation. warp threads, or again using special combs. One can for example quote the patent FR 1.395 815 which teaches the realization of a fabric with narrowing on a loom with shuttles, in particular for the execution of ties.

Les sangles obtenues sur métier à navettes, présentent des irrégularités de présentation, de souplesse et d'épaisseur notamment au droit des rétrécissements. De plus, leur prix de revient est élevé par suite d'un faible rendement résultant de la faible vitesse à laquelle travaille ce type de métier.The straps obtained on the shuttle loom have irregularities in presentation, flexibility and thickness, particularly in the face of shrinkage. In addition, their cost price is high due to a low yield resulting from the low speed at which this type of profession works.

Pour remédier à ces inconvénients, il est apparu nécessaire de réaliser des sangles tissées avec rétrécissements localisés, sur des métiers automatiques à faucilles dont la cadence de production est très élevée. Il est connu de réaliser, sur ce type de métier, des sangles droites, sans rétrécissement, comme il ressort du brevet FR 1.249 099.To overcome these drawbacks, it appeared necessary to produce woven straps with localized narrowing, on automatic sickle looms whose production rate is very high. It is known to produce, on this type of trade, straight straps, without shrinking, as is apparent from patent FR 1,249,099.

Afin de pouvoir exécuter ce genre d'article sur des métiers automatiques à faucilles, il a fallu résoudre d'importants problèmes techniques qui ne se posaient pas dans un métier à navettes. Par exemple, il s'avère indispensable de maintenir constant la distance entre la lame extrême du peigne et l'aiguille pour obtenir la continuité de formation de la chaînette au droit des lisières rectilignes de largeur normale ou réduite, et des lisières évasées de raccordement.In order to be able to execute this kind of article on automatic sickle looms, it was necessary to solve important technical problems which did not arise in a shuttle loom. For example, it is essential to keep the distance between the end blade of the comb and the needle constant to obtain the continuity of formation of the chain in line with the straight edges of normal or reduced width, and flared edges connection.

Un tel problème n'existe pas dans un métier à navettes où le peigne est simplement animé d'un mouvement alternatif vertical de bas en haut.Such a problem does not exist in a shuttle loom where the comb is simply driven in a vertical reciprocating movement from bottom to top.

La présente invention s'est fixée pour but, d'une manière simple, efficace et rationnelle, la réalisation de sangles avec rétrécissement transversaux, sur des métiers automatiques à faucilles. L'invention telle qu'elle est caractérisée dans les revendications, résout le problème consistant à créer une sangle qui, quelles que soient les armures de tissage utilisées dans les parties larges et les parties étroites, présente d'un côtéune lisière formée par un point de chaînette obtenue par le travail de l'aiguille du métier quel que soit le système de liage de la trame utilisé, et,du côté opposé une lisière réelle directement obtenue par le retour de la faucille et de la trame.The present invention has set itself the aim, in a simple, efficient and rational manner, of making straps with transverse narrowing, on automatic sickle looms. The invention as characterized in the claims solves the problem of creating a strap which, whatever the weaving weaves used in the wide parts and the narrow parts, has on one side an edge formed by a point chain obtained by working the needle of the loom whatever the weft tying system used, and, on the opposite side an actual selvedge directly obtained by the return of the sickle and the weft.

Le battant du métier automatique à faucille est équipé d'un guide incliné sur lequel se déplace en hauteur par un moyen approprié, un coulisseau muni d'un peigne dont les lames disposées en éventail permettent selon le positionnement dudit coulisseau soit le resserrement des fils de chaîne en vue de l'obtention des parties rétrécies,soit au contraire l'écartement desdits fils de chaîne pour le tissage de la largeur normale de la sangle.The leaf of the automatic sickle loom is equipped with an inclined guide on which moves in height by an appropriate means, a slider provided with a comb whose blades arranged in a fan shape allow the tightening of the wires of warp in order to obtain the narrowed parts, on the contrary, the spacing of said warp threads for weaving the normal width of the strap.

L'inclinaison angulaire du coulisseau autorise le déplacement de la dent extrême du peigne dans un plan parallèle au plan de l'aiguille de tricotage, de manière à former le point de chaînette de la lisière quel que soit le positionnement en hauteur du peigne.The angular inclination of the slide authorizes the displacement of the end tooth of the comb in a plane parallel to the plane of the knitting needle, so as to form the chain stitch of the selvedge regardless of the height positioning of the comb.

Les avantages obtenus grâce à cette invention résident essentiellement dans :

  • - la régularité de tissage, de souplesse et d'épaisseur de la sangle, notamment au droit des rétrécissements,
  • - la rapidité de fabrication avec une ou plusieurs armures, quels que soient les types d'armures,
  • - la possibilité d'obtention sur un même métier, des sangles avec des rétrécissements de largeurs variables et des évasements progressifs de longueurs variables.
The advantages obtained thanks to this invention essentially lie in:
  • - the regularity of weaving, flexibility and thickness of the strap, in particular at the right of the narrowing,
  • - the speed of manufacture with one or more armor, whatever the types of armor,
  • - the possibility of obtaining on the same loom, straps with narrowing of variable widths and progressive flares of variable lengths.

Selon l'invention, le métier automatique à faucille est équipé pour l'obtention de sangles avec rétrécissements transversaux localisés, d'une glissière (1) fixée angulairement sur l'embase du battant (B) de manière à occuper une position inclinée, comme illustré aux figures 7 et 9 des dessins.According to the invention, the automatic sickle loom is equipped for obtaining straps with localized transverse constrictions, a slide (1) fixed angularly on the base of the leaf (B) so as to occupy an inclined position, as illustrated in Figures 7 and 9 of the drawings.

De par sa section profilée, en queue d'aronde, la glissière (1) autorise le guidage à libre coulissement d'un coulisseau porte-peigne (2) en forme d'étrier dont la découpe trapézoïdale autorise le libre passage de la nappe des fils de chaînette (F)sollicités à la façon connue, par la faucille (3) d'amenée du fil de trame (T).By virtue of its profiled section, in dovetail, the slide (1) authorizes the free sliding guidance of a comb-carrying slide (2) in the shape of a stirrup whose trapezoidal cut-out allows the free passage of the web of chain thread (F) floor licit in the known way, by the sickle (3) for feeding the weft thread (T).

Le coulisseau (2) permet au droit de son ouverture, la fixation faciale d'un peigne (4) dont les lames (4a) sont disposées symétriquement en forme de V, de manière à obtenir entre lesdites lames, un écartement maximum au droit de la grande base, et au contraire un écartement minimum au droit de la petite base.The slide (2) allows the right of its opening, the facial attachment of a comb (4) whose blades (4a) are arranged symmetrically in a V shape, so as to obtain between said blades, a maximum spacing at the right of the large base, and on the contrary a minimum spacing to the right of the small base.

De ce fait, l'on conçoit que le déplacement en hauteur du coulisseau (2) permet d'éloigner ou de rapprocher entre-eux les fils de chaîne (F) pour obtenir soit la largeur normale de la sangle,soit la largeur réduite avec évasement progressif de raccordement de ces deux parties.Therefore, it is understood that the displacement in height of the slide (2) makes it possible to distance or bring together the warp threads (F) to obtain either the normal width of the strap, or the reduced width with progressive flaring of connection of these two parts.

Il est important de considérer que la fixation angulaire d'une manière inclinée de la glissière (1) et par suite du coulisseau (2) autorise le positionnement rigoureux de la lame extrême (4b) du peigne (4) dans un plan parallèle au plan de déplacement de l'aiguille mobile (5) servant à former les points de chaînettes de la lisière de la sangle. Cette caractéristique permet, lors de la course en hauteur du coulisseau (2), d'obtenir d'un côté la continuité de formation de la chaînette au droit des lisières rectilignes de largeur normale ou réduite et des lisières évasées de raccordement.It is important to consider that the angular fixing in an inclined manner of the slide (1) and consequently of the slide (2) authorizes the rigorous positioning of the extreme blade (4b) of the comb (4) in a plane parallel to the plane movement of the movable needle (5) used to form the chain stitches of the edge of the strap. This characteristic makes it possible, during the stroke in height of the slide (2), to obtain on one side the continuity of formation of the chain at the right of the rectilinear selvedges of normal or reduced width and flared selvedges of connection.

On note également que la trame peut être liée suivant plusieurs systèmes connus, notamment par le système à un ou plusieurs fils d'apports, obtenu par l'emploi du doigt (13) inhérent au métier automatique à faucille.It is also noted that the weft can be linked according to several known systems, in particular by the system with one or more filler wires, obtained by the use of the finger (13) inherent in the automatic sickle loom.

Le moyen de déplacement en hauteur dans les deux sens du coulisseau porte-peigne (2) est assuré,par exemple, au moyen d'un vérin (6) fixé sur le battant (B) du métier, ou encore sur une partie fixe, dont le piston est relié audit coulisseau(2)soit par des moyens pneumatiques, soit par des moyens mécaniques. Le piston dudit vérin (6) est commandé automatiquement par l'intermédiaire de chaque impulsion d'un capteur (7) disposé en regard d'un organe mobile du métier tel que le battant (B), suivant une course de longueur déterminée et réglable. De ce fait, l'opération de rétrécissement de la sangle (S) est progressive, pour obtenir ainsi à volonté,d'une part, des évasements (Sa - Sb) de raccordement de longueurs variables et, d'autre part, des largeurs rétrécies (la-lb) de dimensions variables, compte-tenu de l'amplitude de la course du peigne (4). Ces dispositions sont illustrées aux figures 2, 3, 4, 5 et 6 où l'on voit des sangles (S) de même largeur (1) obtenues directement sur le métier à faucille avec des zones de rétrécissement et des évasements de dimensions variables. On remarque également, selon la figure 5, que la partie rétrécie (lc) de la sangle (S) comporte une lisière rectiligne et continue, effectuée soit du côté point de chaînette, soit du côté lisière réelle.The means of displacement in height in both directions of the comb-carrying slide (2) is provided, for example, by means of a jack (6) fixed on the leaf (B) of the loom, or even on a fixed part, the piston of which is connected to said slide (2) either by pneumatic means or by mechanical means. The piston of said cylinder (6) is controlled automatically by means of each pulse from a sensor (7) arranged opposite a mobile member of the trade such as the wing (B), following a stroke of determined and adjustable length. . Therefore, the narrowing operation of the strap (S) is progressive, thus obtaining desire, on the one hand, for flares (Sa - Sb) of connection of variable lengths and, on the other hand, narrowed widths (la-lb) of variable dimensions, taking into account the amplitude of the stroke of the comb (4). These arrangements are illustrated in Figures 2, 3, 4, 5 and 6 where we see straps (S) of the same width (1) obtained directly on the sickle loom with narrowing zones and flares of variable dimensions. We also note, according to Figure 5, that the narrowed part (lc) of the strap (S) has a rectilinear and continuous selvedge, made either on the chain stitch side or on the real selvedge side.

Il faut également noter que les impulsions du capteur (7) sont transmises à un boîtier éléctronique (8) muni de compteurs, qui distribue lesdites impulsions nécessaires, simultanément au moyen de déplacement en hauteur du peigne, à un donneur de trame (10) et à un régulateur de tirage de la sangle tissée comme illustré figure 11.It should also be noted that the pulses from the sensor (7) are transmitted to an electronic unit (8) provided with counters, which distributes said necessary pulses, simultaneously by means of displacement in height of the comb, to a weft donor (10) and to a woven strap draft regulator as illustrated in Figure 11.

Le dispositif donneur de trame est asservi à un variateur de vitesse (9) couplé sur le système de commande (6) du peigne (4) par l'intermédiaire du boîtier électronique (8), pour agir sur un distributeur de trame (10). Le donneur (10) de trame (T) permet ainsi automatiquement le ralentissement proportionnel de la distribution lors du tissage des largeurs rétrécies (la-lb) et des évasements (Sa - Sb), pour éviter les flottements et le relâchement de la tension. Ce distributeur (10) peut être de tout type connu, tel à flasques coniques rapprochés, selon la figure 11, ou encore du type semi positif.The weft donor device is slaved to a speed variator (9) coupled to the control system (6) of the comb (4) via the electronic unit (8), to act on a weft distributor (10) . The weft donor (10) (T) thus automatically allows the proportional slowing down of the distribution during the weaving of the narrowed widths (la-lb) and the flares (Sa - Sb), to avoid floating and the relaxation of the tension. This distributor (10) can be of any known type, such as close conical flanges, according to FIG. 11, or else of the semi positive type.

Le régulateur de tension agissant sur le rouleau de réception (12) de la sangle (S) est asservi à un variateur de vitesse (11) couplé également sur le système de commande du peigne (4) par l'intermédiaire du boîtier électronique de commande (8). Il en résulte un effort proportionnel plus important lors du tissage des parties rétrécies (la-lb) et des évasements (Sa-Sb), pour compenser l'effort de frappe plus important du battant (B) puisque s'exerçant sur une moindre largeur.The tension regulator acting on the receiving roller (12) of the strap (S) is controlled by a speed variator (11) also coupled to the comb control system (4) via the electronic control unit. (8). This results in a greater proportional force when weaving the narrowed parts (la-lb) and flares (Sa-Sb), to compensate for the greater striking force of the leaf (B) since it is exerted on a narrower width .

Il est évident que les dispositions peuvent éventuellement s'appliquer à des rubans ou autres articles similaires sur tout type de métier automatique.It is obvious that the provisions may possibly apply to ribbons or other similar articles on any type of automatic loom.

Il faut considérer également que pour la compréhension des dessins, on a illustré le côté point de chaînette avec un effet de bordure dentelée, étant observé qu'en réalité ce bord donne un effet rectiligne comme le bord côté lisière réelle.It should also be considered that for the understanding of the drawings, the chain stitch side has been illustrated with a serrated edge effect, it being observed that in reality this edge gives a rectilinear effect like the edge on the real selvedge side.
