La presente invention a pour objet un dispositif destine ä, eire monte sur les me- tiers servant ä tisser coniquement los galcns et rubans plisses ou tuyautes en vue de les ma.intenir tendus @da.ns tonte Ileur la.rgeur Pendant leur tissage, quelle que sofft la clif- ference de longueur existant entre leur Bord 1e plus court et leur Bord 1e plus Jong, et d'obtenir par consequent un entrainement uniforme de ces galons et rubans. Device applicable to looms for conically weaving pleated or fluted braids and ribbons, with a view to keeping them stretched across their entire width during their weaving. The subject of the present invention is a device intended to be mounted on the looms used to conically weave the galcns and pleated ribbons or pipes with a view to keeping them stretched in the shearing width during their weaving, whatever the difference in length between their shortest edge and their longest edge, and consequently to obtain a uniform training of these braids and ribbons.

Ce dispositif de tension se monte sur los metiers ä tisser, sur la banquine, imm6diate- ment devant 1e battant. Il reQoit 1e ruban plissä ou tuyaute des sa sortie du peigne et comprend deux galets cylindriques paralle les fa.iblement espaces dont 1'un au moins est rugueux et qui sont entraines selon des mou- v ements de rotation en sens inverse par un engrenage empruntant sa force au regulateur du metier sur la tige duquel est place, ä cet effet, un pignon d'entrainement. Ce pignon tra,nsmet sa rotation, par 1'intermediaire dune chaine, ä 1'engrenage du dispositif qui fait 1'objet de 1'invention. Entre les deux ga lets est engage 1e cöte 1e plus long du galon ou ruban, afin qu'il sofft entraine plus vife quo son cöte 1e plus court entrainä comme or- dinairement par le regulateur du metier, afin de rattraper son exces de longueur par rap- port ä ce cöte 1e plus court. Ces galets sont montes dans un bäti en deux pieces, chacun dans l'une de celles-ei, se fixant en Position reglable sur 1e bäti du metier et reliees par un axe loge dans deux manchons superposes faisant p;artie ehacun d'une @de;s pieces du- dit bäti. Cet axe est fixe et presente ä sa Partie superieure un chapeau @egalement fixe entre lequel et 1e manchon superieur filete interieurement, est plaee sur 1e meme axe un bouton molete ä tige presentant un pas de vis en Prise avec 1e pas de vis correspon- dant du manchon superieur. En vissant ce bouton dans 1e pas de vis du manchon pre- cite, ou en 1e devissant, 1e bouton ne pou- vant se Uplacer longitudinalement Sur Pate, an fait vagier F6cartement des ma.nchons et, par Suite, des deux galets selon Fepaisseur du galon ou ruban ä faire passer entre eux. This tensioning device is mounted on the looms, on the banquine, immediately in front of the leaf. It receives the pleated or piped ribbon as soon as it comes out of the reed and comprises two cylindrical rollers parallel to the slightly spaces, at least one of which is rough and which are driven according to rotational movements in the opposite direction by a gear borrowing its force to the loom regulator on the rod of which is placed, for this purpose, a drive pinion. This pinion transmits its rotation, by means of a chain, to the gear of the device which is the subject of the invention. Between the two rollers is engaged the 1st longest side of the braid or ribbon, so that it is dragged faster than its 1st shorter side dragged as ordinarily by the regulator of the loom, in order to catch up its excess length by compared to this side the shortest. These rollers are mounted in a two-piece frame, each in one of these, fixing in an adjustable position on the first frame of the loom and connected by an axis housed in two superimposed sleeves forming part each of a @ of; s parts of said frame. This axis is fixed and has at its upper part a cap, also fixed, between which and the internally threaded upper sleeve, is placed on the same axis a knurled knob with a stem having a screw pitch in engagement with the corresponding screw pitch. of the upper sleeve. By screwing this button in the thread of the aforementioned sleeve, or by unscrewing it, the button cannot be placed longitudinally On the Pate, causing the spacing of the sleeves to wander and, subsequently, of the two rollers according to the thickness braid or ribbon to pass between them.

Le dessin annexe represente, a titre d'exemple, une forme d'execution de 1'objet de Finvention. The appended drawing represents, by way of example, one form of execution of the object of the invention.

Fig. 1. est une vue en perspective de 1'en- semble du dispositif fix6 contre la charpente du m6tier, 1e trait Passant entre les galets montrant sch.ematiquement la Position et la progression du tissu; Fig. 2 est une vue fragmentaire en pers- pective schematis6e montrant 1e Passage du cW plisse du tissu entre les galets; Fig. 3 est une vue du bouton inolete per- mettant de r6gler 1'6cartement des galets. Le dispositif de tension et d'entrainement represente est fix6 contre la charpente ou bäti A du mutier, par exemple ä. Faide de vis a traversant une Plaque de Support 1. Contre cette Plaque 1 est maintenue, ä Faide de vis 2, une semelle 3 perc6e de fentes ho rizontales 3a dans lesquelles peuvent jouer les vis 2, ce qui permet de regler la Posi tion Jongitudinale de cette semelle par rap- port ä la charpente A. Contre la semelle 3 est appliqu6e une autre semelle plus petite .1 perck de fentes verhcales 4a dans lesquelles peuvent jouer des vis 5 implant6es dans la semelle 3, ce qui permet de regler la Position verticale de la semelle 4 par rapport ä la charpente ou bäti A du m6tier. Fig. 1. is a perspective view of the entire device fixed against the framework of the loom, the line Passing between the rollers schematically showing the Position and the progression of the fabric; Fig. 2 is a fragmentary diagrammatic perspective view showing the passage of the cW pleat of the fabric between the rollers; Fig. 3 is a view of the inolete button making it possible to adjust the spacing of the rollers. The tension and drive device represented is fixed against the frame or frame A of the mule, for example ä. With the help of screws passing through a Support Plate 1. Against this Plate 1 is held, with the help of screws 2, a flange 3 pierced with horizontal slots 3a in which the screws 2 can play, which makes it possible to adjust the Joint Position. of this sole with respect to the frame A. Against the sole 3 is applied another smaller sole .1 perck of vertical slots 4a in which screws 5 implanted in the sole 3 can play, which makes it possible to adjust the position vertical of the sole 4 with respect to the frame or frame A of the trade.

Deux flasques 6, 7 sont solidaires (par exemple venues de fonderie) de la semelle de fixation 4 et sensiblement perpendiculaires ä elle. La flasque 6 Porte un manchon cylin- drique 8 6vide de bas en haut dans lequel est fixe un axe 9. Sur cet axe, et au-dessus du manchon 8, est monte un second manehon cylindrique 10 Agalement evide, .et superpos6 au Premier, ce second manchon 6tant filete interieurement Jans sa. pai-tie supkieure pour recevoir 1e filetage correspondant 11 d'un bouton molete 12 6galement taraude et monte Sur Faxe 9. Cet axe 9 se termine par un Chapeau 9b (fig. 3) pourvu dune encoche 9a. ce ch:apeau e:mpecha.nt 1e houton 1-2 @de se,de- placer dans 1e sens vertical. Ce bouton molet@, ou autrement rendu rugueux Sur son pour- tour pour permettre une meilleure pr6hension, Porte ä sa Partie sup6rieure un cadran 12a qui, en se d6plagant avee la rotation du bou- ton par rapport ä 1'encoche 9,e du Chapeau fixe, renseigne exactement Fusager Sur Fim- portance du tour de vis donn6 par ce bou- ton dans 1e manchon 10, et, par Suite du de- placement obtenu dans 1e RTIID="0002.0275" WI="7" HE="4" LX="1705" LY="558"> sens vertical par ce manchon Sur laxe 9, ddplacement qui se traduit par un 6cartement plus ou moins prononce du galet sup6rieur 18 par rapport au galet inferieur. Two flanges 6, 7 are secured (for example from a foundry) to the fixing sole 4 and substantially perpendicular to it. The flange 6 carries a cylindrical sleeve 8 6 empty from bottom to top in which is fixed an axis 9. On this axis, and above the sleeve 8, is mounted a second cylindrical crank 10 Also hollow, and superimposed on the first , this second sleeve 6tant internally threaded Jans sa. supkieure pai-tie to receive the first corresponding thread 11 of a knurled knob 12 6also taps and mounts on Faxe 9. This axis 9 ends in a hat 9b (fig. 3) provided with a notch 9a. this hat prevents button 1-2 from moving in the vertical direction. This knurled knob, or otherwise roughened on its periphery to allow a better grip, bears at its upper part a dial 12a which, by moving with the rotation of the knob relative to the notch 9,e of the Fixed cap, informs the user exactly about the importance of the turn of the screw given by this button in the first sleeve 10, and, as a result of the displacement obtained in the first RTIID="0002.0275" WI="7" HE="4 "LX="1705" LY="558"> vertical direction by this sleeve On the axis 9, displacement which results in a more or less pronounced separation of the upper roller 18 with respect to the lower roller.

Avee 1e manahon superieur 10 est soli- daire (par exemple venue de fonderie) une console 13 terminee par deux flasques 14, 15 placks dans Falignement respectif des flas- ques inf6rieures 6, 7. Dans Ces flasques tou- rillonne un axe horizontal 16 et Jans les flasques sup6rieures 14 et 15 tourillonne de meme un axe horizontal 17. Attached to the upper sleeve 10 (for example from a foundry) is a bracket 13 terminated by two flanges 14, 15 placed in the respective alignment of the lower flanges 6, 7. In these flanges a horizontal axis 16 and Jans the upper flanges 14 and 15 likewise pivot a horizontal axis 17.

Sur chaeun des axes 16 et 17 sont ca16s un pignon 19 et un ga.let 18 ä p6riph6rie ru- gueuse dort 1'extr6mite laterale 18a est de plus faible diametre et ne vieret pas en Prise avec Fautre. Les diametres de Ces galets et de Ces pignons sont etudiAs pour que, quand les dents d'un des pignons penetrent ä fond dans les entre-dents de 1'autre pignon, les pe- riphAries des deux galets 18 soient serrks Tune contre Fautre . On each of the axes 16 and 17 are fitted a pinion 19 and a roller 18 with a rough periphery on which the lateral end 18a is of smaller diameter and does not come into engagement with the other. The diameters of these rollers and of these sprockets are studied so that, when the teeth of one of the sprockets penetrate fully into the between-teeth of the other pinion, the peripheries of the two rollers 18 are tight against each other.

Avec 1e pignon inferieur 19 engrene constamment un second pignon 20 monte Sur un axe 21 tourillonn6 dans les flasques 6, 7. Ce pignon 20 engrene ä son tour cons- tamment avec un troisieme pignon 22 Sur faxe duquel est cal6e une roue ä chaine 2'3 reli6e par une chaine 24 avee une autre roue ä, chaine (non repr6sentee) entrain6e par la tige du regulateur du metier. Gräce ä cette transmission, les galets 18, 18 tournent (dans 1e sens indique par les fleches) au für et ä mesure de la marche du m6tier. With the lower pinion 19 constantly meshes a second pinion 20 mounted on an axis 21 journalled in the flanges 6, 7. This pinion 20 in turn meshes constantly with a third pinion 22 on the axle of which is wedged a chain wheel 2'. 3 connected by a chain 24 with another wheel, chain (not shown) driven by the rod of the loom regulator. Thanks to this transmission, the rollers 18, 18 rotate (in the direction indicated by the arrows) as the loom progresses.

Le fonctionnement du dispositif est fa- cile 5, comprendre en examinant la fig. 2. Le Probleme ä resoudre est d'entrainer, grä.ce ä une tension reguliere, 1e cet6 plisse ou tuyaute Gb du galon G dont Fautre cöte Ga pre- sente une lisiere (souvent maintenue rigide par un fil metallique W loge dedans) entrai- nee par 1e regulateur ordinaire du metier, de fa(#on que les fils de chaine correspondant au cöte plissA Gb et qui sont evidemment plus lon.gs (par exe.mple deux fois plus l.ongs) que les fils de chaine du c6t6 Ga, soient entraines aussi vite qu'eux et qu'ä chaque Coup de battant du metier (ce battant n'e- tant pas represente et etant placg en amont des galets 18, 18), la navette porte-trame passe toujours bien perpendiculairement ä toute la nappe des fils de ehaine. The operation of the device is easy 5 to understand by examining fig. 2. The problem to be solved is to train, thanks to a regular tension, the pleat or piping Gb of the braid G whose other side Ga has a selvedge (often held rigid by a metal wire W lodged inside) - born by the 1st ordinary regulator of the trade, so that the warp threads corresponding to the plissA Gb side and which are obviously longer (for example twice as long) than the warp threads of the c6t6 Ga, are driven as quickly as them and that at each stroke of the loom leaf (this leaf not being represented and being placed upstream of the rollers 18, 18), the weft-carrying shuttle always passes well perpendicular to the entire web of chain yarns.

Ce resultat est atteint gräce au present dispositif puisque 1e c6t6 plisse ou tuyaute Gb du galon passe entre les galets 18, 18 dont an fait varier ä, volonte 1'ecartement ä, Faide du bouton 12 et dopt la vitesse de ro- tation fait progresser ledit c6t6 plisse Gh ä une vitesse correspondant ä la vitesse de progression libre imprimge par 1e regulateur du c6t6 non plisse Ga. Un engrenage, non re- presente, constitue par une roue ä. chaine (non representee) entrainge par la tige du regulateur du metier,. permet d'obtenir la vi- tesse adAquate ä ce travail. Cette roue ä chaine est interchangeable, son diametre per- mettant, suivant qu'il est petit ou Brand, d'entrainer 1e dispositif ä une vitesse plus ou moins Brande exactement proportionnge ä la vitesse de 1'entrainement ä obtenir. Cette vitesse d'entrainement doit varier, en effet, suivant que 1e tuyautage ou plissage est plus ou moins accentue, c'est-ä-dire que 1e cöte Gb du ruban est plus ou moins long. This result is achieved by means of the present device since the pleated or fluted side Gb of the braid passes between the rollers 18, 18, the spacing of which is varied at will, the spacing at will, the aid of the button 12 and the speed of rotation advances said c6t6 pleats Gh at a speed corresponding to the speed of free progression imprinted by the regulator of the non-pleated c6t6 Ga. A gear, not shown, constitutes a wheel ä. chain (not shown) driven by the rod of the loom regulator. provides the correct speed for the job. This chain wheel is interchangeable, its diameter making it possible, depending on whether it is small or Brand, to drive the device at a more or less Brande speed exactly proportionate to the speed of the drive to be obtained. This driving speed must vary, in fact, depending on whether the piping or pleating is more or less accentuated, that is to say whether the side Gb of the tape is more or less long.

Si, comme c'est generalement 1e cas, 1e galon G comporte une lisiere Ga avec ou sans fil mgtallique raidisseur W, cette lisiere passe librement soit entre les extr & mitA.s 18a de plus faible diametre des galets 18, soit dans un endroit quelconque exterieur aux ga- lets situe (si Fon se refere ä la fig. 2) ä Bauche de ceux-ei, ca.r il est evident que la lisiere W et sa Partie non tuyautee Ga pourrait au contraire se trouver ä, Bauehe au lieu de se trouver ä droite comme represente au dessin. L'ecartement exactement requis des galets 18 est obtenu en vissant legerement 1e bou- ton 12 dans 1e pas de vis du manchon 10, ce qui oblige ce manchon, et par Suite la flasque 1'8 et 1e galet superieur 18 dont il est solidaire, ä remonter Sur Faxe 9. 0n peut ainsi modifier 1'ecartement des galets, par exemple selon Npaisseur du ruban ou galon. If, as is generally the case, the first braid G comprises a selvage Ga with or without a stiffening metal wire W, this selvage passes freely either between the ends & mitA.s 18a of smaller diameter of the rollers 18, or in a place any exterior to the pebbles located (if we refer to fig. 2) at Bauche of these, because it is obvious that the edge W and its non-trimmed part Ga could on the contrary be found at, Bauehe at the instead of being on the right as shown in the drawing. The exactly required spacing of the rollers 18 is obtained by slightly screwing the first knob 12 into the first thread of the sleeve 10, which obliges this sleeve, and subsequently the flange 18 and the first upper roller 18 of which it is integral. , to go up on Faxe 9. 0n can thus modify the spacing of the rollers, for example according to Nthickness of the ribbon or braid.
