Abstract

Knitting apparatus for producing a seamless tube, comprises needles (3) mounted in two frames (1, 2) that are oppositely inclined in the vertical plane so the needles do not cross over during normal knitting. The spacing of the needles in each frame is the same as the spacing between a pair of opposed needles in the two frames.

Description

La présente invention se rapporte à un métier à tricoter rectiligne à deux fontures parallèles dont les inclinaisons dans le plan vertical sont choisies pour que leurs aiguilles ne se croisent pas pendant leur course normale de tricotage, pour permettre la confection d'un tricot tubulaire sans couture.The present invention relates to a knitting loom straight with two parallel needle beds with inclinations in the vertical plane are chosen so that their needles do not cross during their normal course of knitting, to allow the making of a tubular knitting seamless.

On a déjà proposé dans le EP 0552588 une machine à tricoter rectiligne à deux fontures rectilignes parallèles pour réaliser des tricots sans couture. Le problème que l'on rencontre avec une telle machine réside dans le fait que des rainures apparaissent dans le tricot correspondant au passage du fil à tricoter d'une fonture à l'autre. Pour réaliser un tricot tubulaire sur une telle machine, les aiguilles des deux fontures ne doivent normalement pas se croiser, sauf lorsque l'on doit réunir les deux parties tubulaires avant et arrière, en particulier lors du tricotage de l'entrejambe dans le cas d'un collant ou d'un pantalon notamment. De ce fait, les aiguilles d'une fonture sont décalées par rapport aux aiguilles de l'autre fonture pour permettre leur croisement au moment de la réunion des deux nappes de tricot.EP 0552588 has already proposed a machine for knit straight with two parallel straight needle beds to make seamless knits. The problem we encounter with such a machine lies in the fact that grooves appear in the knit corresponding to the passage knitting yarn from one bed to another. To realize tubular knitting on such a machine, the needles two needle beds should not normally cross, except when the two tubular parts must be joined before and back, especially when knitting the crotch in the case of tights or pants in particular. From this done, the needles of a needle bed are offset from to the needles of the other needle bed to allow their crossing when the two knitted tablecloths meet.

Compte tenu notamment de cette disposition décalée des aiguilles des deux nappes, la longueur de fil entre deux aiguilles adjacentes d'une même fonture est sensiblement plus courte que celle entre deux aiguilles des deux fontures, lors du passage du fil à tricoter d'une fonture à l'autre, d'où la production d'une maille plus longue faisant apparaítre une rainure longitudinale le long du tricot tubulaire, étant donné que toutes les mailles plus longues sont alignées verticalement ou longitudinalement le long du tricot tubulaire. Taking into account in particular this staggered arrangement of needles of the two plies, the length of thread between two adjacent needles of the same needle bed is substantially shorter than that between two needles of the two needle beds, when passing the knitting yarn from one needle to another, from where the production of a longer mesh making appear a longitudinal groove along the tubular knit, since all the longer meshes are aligned vertically or longitudinally along the tubular knit.

Le but de la présente invention est d'apporter une solution permettant de remédier, au moins partiellement, au défaut constaté.The purpose of the present invention is to provide a solution allowing to remedy, at least partially, the defect found.

A cet effet, la présente invention a pour objet un métier à tricoter rectiligne à deux fontures parallèles selon la revendication 1.To this end, the present invention relates to a straight knitting machine with two parallel needle beds according to claim 1.

L'intérêt de la solution proposée réside dans le fait qu'elle est simple à réaliser et à mettre en oeuvre, puisqu'elle entraíne relativement peu de modifications de la machine et les modifications nécessaires ont recours à des moyens connus de l'homme de l'art.The advantage of the proposed solution lies in the fact that it is simple to carry out and to implement, since it results in relatively few machine modifications and the necessary modifications use means known to those skilled in the art.

L'invention part du principe que le défaut constaté ne peut être éliminé, ou au moins fortement atténué, que si la distance séparant les aiguilles voisines des deux fontures est la même que celle qui sépare deux aiguilles adjacentes de chaque fonture. En effet grâce à cette disposition, les mailles formées entre deux aiguilles adjacentes d'une même fonture ont la même longueur que les mailles formées pour réunir les deux nappes parallèles tricotées par chaque fonture, en faisant passer le fil d'une aiguille d'une fonture à l'aiguille voisine de l'autre fonture.The invention is based on the principle that the defect observed does not can be eliminated, or at least greatly attenuated, only if the distance separating the neighboring needles from the two needle beds is the same one that separates two adjacent needles of each needle bed. Thanks to this arrangement, stitches formed between two adjacent needles of the same beds have the same length as the stitches formed for join the two parallel tablecloths knitted by each needle, by passing the thread of a needle of a needle to the needle next to the other needle bed.

Pour obtenir ce résultat, il est généralement nécessaire de réduire l'écartement entre les deux fontures, ce qui peut poser certains problèmes de chevauchement des platines de décrochage en raison du rapprochement des fontures.To achieve this, it is usually necessary reduce the distance between the two needle beds, which may cause some deck overlap issues due to the closeness of the needle beds.

Divers solutions à ce problème qui peut se poser sont proposées dans le cadre de cette invention.Various solutions to this problem which may arise are proposed in the context of this invention.

Bien que l'écartement entre les aiguilles des extrémités des nappes de tricots adjacentes soit égal au pas des aiguilles des deux fontures, un défaut peut encore subsister en raison des différences de tension qui peuvent se produire dans le fil. Une solution à ce problème est également proposée. Although the spacing between the needle ends sheets of adjacent knits is equal to the pitch of needles of the two needle beds, a defect may still remain due to voltage differences that may occur in the thread. A solution to this problem is also proposed.

Enfin, les aiguilles des deux fontures se trouvant vis-à-vis les unes des autres, il est nécessaire de trouver une solution pour réunir les deux nappes de tricot pour tricoter l'entrejambe notamment.Finally, the needles of the two needle beds opposite from each other, it is necessary to find a solution to join the two knitting tablecloths for knitting the crotch in particular.

  • FIG. 6 illustrates a view of the double cam path with the respective needles working with the respective cam paths.

    • Les figures 1 et 2 illustrent un métier à tricoter comportant deux fontures rectilignes parallèles 1, 2 chacune munie d'une pluralité d'aiguilles à tricoter 3. Chaque aiguille d'une fonture 1 est disposée vis à vis d'une aiguille de l'autre fonture 2. L'écartement entre les fontures 1 et 2 est choisi pour que l'espace d1 séparant deux aiguilles 3 disposées vis à vis l'une de l'autre correspondent pratiquement au pas d2 séparant deux aiguilles adjacentes d'une des fontures 1, 2.Figures 1 and 2 illustrate a knitting loom comprising two parallel straight needle beds 1, 2 each provided with a plurality of knitting needles 3. Each needle a needle bed 1 is arranged opposite a needle on the other bed 2. The spacing between the beds 1 and 2 is chosen so that the space d1 separating two needles 3 arranged opposite one another correspond practically in step d2 separating two adjacent needles from one of needle beds 1, 2.

    Ce métier comporte encore des platines de décrochage 4 et 5 disposées entre deux aiguilles de tricotage 3 sur trois, les platines 4 d'une fonture 1 étant décalées par rapport aux platines 5 de l'autre fonture 2, de sorte que chaque platine 4 de la fonture 1 se trouve en face d'un espace libre 6 de l'autre fonture 2 et chaque platine de la fonture 2 se trouve en face d'un espace libre 7 de la fonture 1. Grâce à cette disposition, les platines de décrochage 4 et 5 peuvent se déplacer librement. Chaque maille est retenue par une platine 4, 5 située d'un seul côté de l'aiguille de tricotage 3 qui tricote cette maille.This trade also includes stall plates 4 and 5 arranged between two knitting needles 3 on three, the plates 4 of a needle bed 1 being offset by compared to the decks 5 of the other bed 2, so that each plate 4 of the needle bed 1 is located opposite a free space 6 of the other needle bed 2 and each plate of the bed 2 is in front of a free space 7 of the bed 1. Thanks to this arrangement, the stall plates 4 and 5 can move freely. Each mesh is retained by a plate 4, 5 located on one side of knitting needle 3 which knits this stitch.

    Comme on peut le voir de la figure 2, les tiges 3a des aiguilles 3 sont de préférence reliées à leurs extrémités 3b par un double coude 3c, permettant d'augmenter l'écartement entre les tiges 3a et de renforcer ainsi les fontures 1, 2.As can be seen in Figure 2, the rods 3a of needles 3 are preferably connected at their ends 3b by a double bend 3c, allowing to increase the spacing between the rods 3a and thus reinforce the needle beds 1, 2.

    Les inclinaisons entre les aiguilles 3 sont telles que lors du tricotage normal, les aiguilles ne se croisent pas et tricotent ainsi deux rangées de mailles indépendantes, le fil passant d'une fonture 1 à l'autre 2 et vice versa à des endroits choisis pour relier les deux nappes tricotées et former un tricot tubulaire, comme décrit par exemple dans le EP 00810150.3 du même titulaire auquel on pourra se référer pour plus de détail, ou encore dans le EP 0552588 susmentionné. En augmentant la course des aiguilles 3, on peut réunir les deux nappes de tricot pour tricoter l'entrejambe d'un collant ou d'un pantalon.The inclinations between the needles 3 are such that during normal knitting, the needles do not cross and knit two independent rows of stitches, the thread passing from a needle bed 1 to another 2 and vice versa to locations chosen to connect the two knitted tablecloths and form a tubular knit, as described for example in the EP 00810150.3 from the same holder to which reference may be made for more details, or in EP 0552588 above. By increasing the stroke of needles 3, we can join the two knitting tablecloths to knit the crotch tights or pants.

    Etant donné que l'espace séparant les deux aiguilles 3 qui se font face des deux fontures 1, 2, à l'endroit où le fil à tricoter passe d'une fonture à l'autre, est égal au pas séparant deux aiguilles adjacentes 3 d'une même fonture, les longueurs de fil à tricoter sont égales de sorte que les mailles sont régulières même lors du passage d'une fonture à l'autre.Since the space separating the two needles 3 facing the two needle beds 1, 2, where the knitting yarn goes from one needle to another, is equal to not separating two adjacent needles 3 from the same needle bed, the lengths of knitting yarn are equal so that the stitches are regular even when passing from a needle bed to the other.

    La variante illustrée par les figures 3 et 4 diffère des figures 1 et 2 par le fait que les platines de décrochage 4', 5' des deux fontures sont ici les unes en face des autres. Toutefois, comme l'écartement entre les fontures 1 et 2 fait que si il s'agissait de platines normales elles se télescoperaient en position de décrochage, les platines 4', 5' de la figure 4 sont conformées pour ne pas se rencontrer, leurs parties actives 4'a, 5'a étant décalées verticalement l'une par rapport à l'autre pour se situer l'une au-dessous de l'autre en position de décrochage des aiguilles 3. Cette variante permet donc de conserver la disposition habituelle des platines de décrochage, c'est-à-dire une platine entre chaque aiguille.The variant illustrated in Figures 3 and 4 differs Figures 1 and 2 by the fact that the stall plates 4 ', 5' of the two needle beds are here opposite each other other. However, as the spacing between the needle beds 1 and 2 means that if they were normal plates they would would telescope in the off-hook position, the 4 'plates, 5 ′ of FIG. 4 are shaped so as not to meet, their active parts 4'a, 5'a being vertically offset one relative to the other to lie one below on the other hand, in the release position of the hands 3. This variant therefore allows to keep the usual arrangement stall plates, i.e. a plate between each needle.

    La figure 5a montre une rangée de boucles de fil destinées à former une rangée de mailles, la moitié gauche de cette figure correspond aux mailles tricotées sur une fonture et la moitié droite, aux mailles tricotées sur l'autre fonture. Ces boucles sont régulières, toutes de même longueur, mais on constate que deux boucles 10 et 11 sont séparées par un espace 12 plus grand que les autres boucles. Ce plus grand écartement provient d'une plus grande longueur de fil à tricoter entre deux aiguilles 3 adjacentes des deux fontures 1, 2.Figure 5a shows a row of wire loops intended to form a row of stitches, the left half of this figure corresponds to the knitted stitches on a needle bed and the right half, knitted on the other needle bed. These loops are regular, all the same length, but we see that two loops 10 and 11 are separated by a space 12 larger than the other loops. This greater distance comes from a greater length of knitting yarn between two adjacent needles 3 of the two needle beds 1, 2.

    Même en ayant le même écartement entre les aiguilles 3 adjacentes des deux fontures 1, 2 qu'entre les aiguilles 3 adjacentes d'une même fonture, selon l'invention, il est possible que la tension du fil diminue en passant d'une fonture à l'autre, d'où la présence de l'irrégularité représentée par la figure 5a. Pour supprimer complètement ce défaut, il est proposé, soit à titre complémentaire à la caractéristique principale de l'invention, soit à titre principal, soit encore en combinaison avec un écartement réduit entre les aiguilles des fontures parallèles et de la mesure que nous allons maintenant décrire, de munir ces fontures d'un chemin de came supplémentaire B, parallèle au chemin principal A.Even with the same spacing between the needles 3 two needle beds 1, 2 only between needles 3 adjacent to the same needle bed, according to the invention, it is thread tension may decrease when passing from one one side to the other, hence the presence of the irregularity shown in Figure 5a. To completely delete this otherwise, it is proposed, either as a supplement to the main characteristic of the invention, either as main, or again in combination with a spacing reduced between the needles of the parallel needlework and the measure that we will now describe, to equip these beds of an additional cam track B, parallel to the main path A.

    Le chemin de came A comporte des cames de montée 14 et de descente 13 et est destiné à travailler avec des aiguilles 3 munies d'un talon 3a. Le chemin de came B comporte des cames de montée 14' et de descente 13' qui sont agencées pour tirer une boucle de fil 11 plus courte que les autres boucles, comme illustré par la figure 5b. Ensuite une came supplémentaire 16 (figure 6) tire sur la boucle 11 pour l'amener à la même longueur que les autres boucles. Cette came 16 ne se trouve pas dans la même chute que les cames 13' 14' qui ont formé la boucle 11 mais dans la chute suivante et dans cette chute suivante, elle est la première came qui agit sur le talon 3'a de l'aiguille 3' . En tirant sur cette boucle 11 plus courte, l'aiguille 3' (figure 6) dont le talon 3'a est en prise avec le chemin de came B prend la longueur supplémentaire de fil dans l'espace 12 plus grand séparant les boucles 10 et 11, réduisant ainsi l'espace entre ces boucles pour ménager un espace 15 (figure 5c) égal aux espaces entre les autres boucles.The cam path A comprises rise cams 14 and downhill 13 and is intended to work with needles 3 provided with a heel 3a. Cam path B has 14 'up and 13' down cams which are arranged to draw a loop of wire 11 shorter than the other loops, as shown in Figure 5b. Then a additional cam 16 (figure 6) pulls on loop 11 to bring it to the same length as the other loops. This cam 16 is not in the same drop as the cams 13 '14' which formed the loop 11 but in the fall next and in this next fall she is the first cam which acts on the heel 3'a of the needle 3 '. Pulling on this shorter loop 11, the needle 3 '(Figure 6) whose heel 3'a is in engagement with the cam path B takes the extra length of wire in space 12 larger separating loops 10 and 11, thereby reducing the space between these loops to provide space 15 (figure 5c) equal to the spaces between the other loops.

    Comme on l'a mentionné précédemment, il est nécessaire de trouver une solution pour réunir les deux nappes de tricot lors du tricotage de l'entrejambe notamment, les aiguilles 3 des deux fontures 1 et 2 situées en face l'une de l'autre ne pouvant pas se croiser. Il est possible d'utiliser des solutions connues. L'une d'elles consiste à sélectionner une aiguille 3 sur deux sur chaque fonture en décalant les aiguilles sélectionner entre les deux fontures. Une autre solution consiste à déplacer longitudinalement par exemple la fonture 1 de la valeur d'un demi pas séparant deux aiguilles par rapport à l'autre fonture 2. L'une ou l'autre de ces solution permet d'augmenter la course des aiguilles 3 et de permettre leur croisement. Ces solutions existent dans d'autres applications et sont connues de l'homme de l'art, de sorte qu'il n'est pas nécessaire de les décrire en détail ici.As mentioned earlier, it is necessary to find a solution to join the two knitted tablecloths especially when knitting the crotch, the needles 3 of the two needle beds 1 and 2 located opposite one of the other cannot cross. It is possible to use known solutions. One of them is to select a needle 3 on two on each needle bed by shifting the needles select between the two needle beds. A other solution is to move longitudinally by example bed 1 of the value of half a step separating two needles relative to the other needle bed 2. One or the other of these solutions makes it possible to increase the travel of needles 3 and allow their crossing. These solutions exist in other applications and are known to skilled in the art, so there is no need to describe in detail here.
