Abstract

The tube comprises layers (1) equipped with rigid vertical rods (3) which alternate with yieldable layers (2) comprising flexible rods (7) of V-shaped profile, so that, under the action of maximum compression by the upper tubes and by the lid of the autoclave vessel, the tube height can never fall below a predetermined minimum value, thus guaranteeing a uniform dyeing action on the yarn wound on conventional spools. <IMAGE>

Description

La présente invention a pour but de réaliser une bobine déformable destinée à la teinture des filés, dont la caractéristique de nouveauté réside dans le fait de pouvoir se comprimer sous la poussée des bobines supérieures et du couvercle de l'autoclave, jusqu'à une valeur minimale pré-établie.The object of the present invention is to produce a deformable spool intended for dyeing yarns, the novelty of which resides in the fact that it can be compressed under the pressure of the upper spools and of the cover of the autoclave, up to a value pre-established minimum.

Le document EP-A-0 257 268 décrit une bobine déformable pour teinture réalisée avec des parois massives qui comprend des couches rigides et des couches déformables. Les couches déformables présentent des fentes ovales inclinées qui ne permettent qu'une faible déformation.Document EP-A-0 257 268 describes a deformable spool for dyeing produced with solid walls which comprises rigid layers and deformable layers. The deformable layers have inclined oval slots which allow only slight deformation.

On sait que les bobines actuellement utilisées pour supporter les bobineaux de filés destinés à être engagés sur les bâtons spécialement employés dans les cuves autoclaves de teinture présentent une structure déformable qui permet auxdits bobineaux d'être comprimés aussi bien sous l'action du poids des bobines superposées que sous l'effet de la fermeture du couvercle supérieur de la cuve.It is known that the reels currently used to support the spools of yarn intended to be engaged on the sticks specially used in autoclave dye tanks have a deformable structure which allows said spools to be compressed as well under the action of the weight of the spools superimposed only under the effect of closing the upper cover of the tank.

L'expérience a permis de vérifier que les bobines porte-bobineaux superposées sur un même bâton sont comprimées de manière différente les unes des autres ; plus particulièrement les bobineaux des couches inférieures sont plus comprimés que ceux des couches supérieures, ne serait-ce que par le poids plus important des bobineaux superposés, en donnant lieu à des différences quant à la quantité de colorant absorbée par chaque bobineau, ce qui entraîne des défauts d'uniformité dans la teinture du filé.Experience has made it possible to verify that the bobbin reels superimposed on the same stick are compressed in a different manner from each other; more particularly the coils of the lower layers are more compressed than those of the upper layers, if only by the greater weight of the superimposed coils, giving rise to differences in the amount of dye absorbed by each coil, which results uniformity defects in the dyeing of the yarn.

Ces inconvénients sont évités moyennant l'adoption de la bobine déformable suivant l'invention telle que définie à la revendication 1 et qui, étant réalisée à l'aide de couches alternées déformables, respectivement rigides, ne peut, lorsqu'elle est comprimée, se déformer au-delà d'une limite maximale déterminée.These drawbacks are avoided by adopting the deformable coil according to the invention as defined in claim 1 and which, being produced by means of alternating deformable layers, respectively rigid, cannot, when compressed, deform beyond a determined maximum limit.

En pratique, sous l'effet du poids des bobines supérieures et surtout sous l'action de fermeture du couvercle de la cuve autoclave, les couches déformables de la bobine sont complètement comprimées alors que les couches rigides ne subissent aucune modification, si bien que la bobine diminue en hauteur jusqu'à une valeur minimale au-delà de laquelle elle ne peut aller.In practice, under the effect of the weight of the upper coils and especially under the action of closing the lid of the autoclave tank, the deformable layers of the coil are completely compressed while the rigid layers do not undergo any modification, so that the coil decreases in height to a minimum value beyond which it cannot go.

L'ensemble des bobines engagées sur le même bâton se déforme ainsi jusqu'à une valeur identique en hauteur, en permettant de la sorte une uniformité de la teinture du filé enroulé sur les bobineaux.All of the coils engaged on the same stick thus deforms to an identical value in height, thereby allowing uniformity in the dyeing of the yarn wound on the coils.

L'invention va maintenant être décrite de manière plus détaillée avec l'aide du dessin annexé, dans lequel :

  • Fig. 1 est une vue de côté d'une bobine élastique porte-bobineaux pour teinture, représentée à la position de sa plus forte extension.
The invention will now be described in more detail with the aid of the appended drawing, in which:
  • Fig. 1 is a side view of an elastic bobbin holder for dyeing, shown at the position of its greatest extension.

Fig. 2 montre la même bobine à la position de compression maximale.Fig. 2 shows the same coil at the maximum compression position.

Comme on peut plus particulièrement le relever en fig. 1, la bobine porte-bobineaux suivant l'invention comprend des couches rigides 1 alternées avec des couches déformables 2.As can be seen more particularly in FIG. 1, the reel-holder coil according to the invention comprises rigid layers 1 alternated with deformable layers 2.

Les couches 1 comportent en fait des tiges verticales 3 qui s'étendent entre deux anneaux adjacents 4 et 5, suivant une direction parallèle à l'axe central de la bobine.The layers 1 in fact comprise vertical rods 3 which extend between two adjacent rings 4 and 5, in a direction parallel to the central axis of the coil.

Entre l'anneau 5 et l'anneau subséquent 6 sont disposés des éléments flexibles 7 conformés pour présenter un profil en V, avec le sommet arrondi positionné au niveau d'un anneau intermédiaire 8.Between the ring 5 and the subsequent ring 6 are arranged flexible elements 7 shaped to present a V-shaped profile, with the rounded top positioned at an intermediate ring 8.

La couche comprise entre les anneaux 5 et 6 peut de ce fait être comprimée sous l'action du poids des bobineaux superposés et également lors de la fermeture du couvercle de la cuve autoclave, jusqu'à être amenée à l'état illustré en fig. 2 où l'on peut noter que les éléments 7 compris entre les deux anneaux 5 et 6 et présentant à l'origine un profil en V, affectent un profil en U qui lors de la compression maximale prend appui par ses côtés contre les bords de l'anneau 8, tandis que les couches adjacentes de la bobine ne subissent aucune déformation, les tiges 3 restant à la position verticale.The layer between the rings 5 and 6 can therefore be compressed under the action of the weight of the superimposed coils and also when the lid of the autoclave tank is closed, until it is brought to the state illustrated in FIG. 2 where it may be noted that the elements 7 comprised between the two rings 5 and 6 and which originally have a V-shaped profile, affect a U-shaped profile which during its maximum compression is supported by its sides against the edges of the ring 8, while the adjacent layers of the coil do not undergo any deformation, the rods 3 remaining in the vertical position.

En définitive, la hauteur de la bobine ne peut être réduite au-dessous de celle qui est visible en fig. 2, si bien que les bobineaux montés sur les différentes bobines engagés sur un même bâton subissent une compression et par là une déformation uniformes.Ultimately, the height of the spool cannot be reduced below that which is visible in fig. 2, so that the coils mounted on the different coils engaged on the same stick undergo compression and thereby uniform deformation.

On conçoit de ce fait les avantages qui sont obtenus à l'aide des bobines suivant l'invention, lesquelles permettent d'obtenir sur le filé enroulé sur les bobineaux un effet de teinture parfaitement uniforme.It is therefore conceivable the advantages which are obtained using the bobbins according to the invention, which allow to obtain on the yarn wound on the bobbins a perfectly uniform dyeing effect.

Claims (1)

  1. Deformable package for dyeing, comprising alternate rigid layers (1) and deformable layers (2), characterised in that the deformable layers are composed of V-shaped flexible elements (7), with the rounded tip positioned level with an intermediate ring (8), adapted to be compressed until they are reduced to a preset minimum value, whereas the rigid layers (1) composed of vertical rods are invariable in height even after pressure has been exerted by the upper packages fixed on the same bar, and/or under the effect of closing the lid of the autoclave, such that the package can no longer be deformed heightwise below a given minimum value, in order that all the packages mounted on the same bar present the same minimum height, thereby enabling the thread wound onto the packages to be dyed evenly.
