  • An aqueous treatment machine is also known, according to German Patent Application DT-A-2 608 527, for dyeing and / or bleaching fabrics in pieces, equipped with a dyeing system comprising a nozzle, and means of circulation of the fabric constituted by a tubing.
  • This machine comprises a fixed drum in which are housed one or more treatment tanks which can be rotated, under the action of the weight of the fabric in pieces.
  • the treatment vessels have a horizontal longitudinal axis, located very slightly above the horizontal longitudinal axis of the drum.

  • the parts to be treated After passing through the dyeing system, the parts to be treated return to the "storage" part of the tanks, passing through a guide duct.
  • the treated tissue is stored on itself.
  • the stored fabric is subjected to high pressures under folding conditions which are not not regular, causing risks of damage to the fabric, detrimental to its quality.
  • the present invention therefore aims to provide an aqueous treatment machine, in particular for dyeing, bleaching or other, fabrics in pieces, which better meets the needs of practice than machines for the same purposes previously known, in particular in that it is provided with circulation, folding, storage and unloading systems which eliminate the drawbacks of the corresponding systems known in the prior art.

  • the dyeing system is found at the descent of the fabric, that is to say near the storage compartment, and where the bath projected outside the dyeing system, interferes with the folding of the fabric and makes folding and storage erratic, especially in the case where two strands are circulating in the same dyeing system to end up in the same storage compartment.
  • the dyeing system in which the dyeing system is located at the ascent of the fabric, that is to say before the means for returning the fabric to the storage compartment, the dye bath leaving the dyeing system flows or is projected onto the fabric 5 as it leaves the storage compartment 4, so that when it enters the folding and storage area, there is no longer any possibility of interference of the bath with the folding of the fabric.
  • the circulation of the fabric 5 in the dyeing system takes place against the flow of the circulation of the dye bath, in the example considered. It is however possible to orient the nozzle 1 so as to cause the circulation of the fabric and the bath in the same direction, that is to say to make the bath rise at the same time as the fabric, in the machine.
  • the motor call roller simultaneously plays the role of folding device; it is then necessary to give this roller a shape other than cylindrical: cf. for example Figures 2, 4, 5 and 7 where the drive roll 6 has an oval section, it being understood that a roll having a polygonal section, for example triangular, would make it possible to obtain a comparable folding, the section not circular of the roller 6 causes regular folds to form.
  • folds can be obtained, according to another embodiment of the invention, by associating a cylindrical drive roller 7, which only plays the role of roller for moving the fabric as it leaves the dyeing system, with a device for formation of folds which can be constituted by a ring (not shown) or by a double funnel 8 (cf. FIG. 6) through which the fabric passes downstream of the take-up roller 7.

  • grooves must be provided on the roller, in the vicinity of its ends, to ensure that the fabric is held in place on the roller. It is not necessary to provide grooves in the vicinity of the ends of the roller when using a cylindrical roller inclined on the horizontal, the flanges of which are arranged parallel to each other in planes perpendicular to the horizontal axis on which the roller is inclined, the flanges then playing the role of maintaining the tissue previously devolved to the grooves.

  • the fabric retains, during its entire storage phase, its folded shape 11 without disturbances, since there is no bath circulation.
  • the formation of folds in the J-shaped box 10 is sufficiently regular, due to the particular conformation of said box, to be able to renounce the provision of particular folding means, the take-up roller 7 then being chosen cylindrical.
  • the ascent of the fabric in the dyeing system, to undergo a new treatment in the machine, is obtained not using the dyeing bath itself, as in the prior art, but essentially by mechanical return means of the fabric described in the above.

  • the circulation, folding and storage device makes it possible to considerably increase the capacity of the machine, by making it possible to simultaneously carry out the aqueous treatment of several strands of fabric in a single dyeing system and their storage in a single compartment, All attempts made with machines in accordance with the prior art, to circulate more than one strand at a time in a single dyeing system , and carrying out storage in a single compartment, ended in failure, in particular, when the strands subjected to the treatment were light fabrics or knitted fabrics: in fact, the circulation of several strands of light fabrics in the same dyeing system, then in the same folding and storage system, leads to the formation of loops and knots which not only hinder and sometimes even prevent the movement of the strands, provoking stop the machine, but also adversely affect the quality of the treatment applied, dyeing in particular.
  • the improvements introduced in accordance with the present invention make it possible to obtain perfect quality of folding and storage, not only in the case of a single strand of fabric, but, above all, when two strands, and even three, are simultaneously in circulation through the same dyeing system and end up, after folding, in the same storage compartment.

  • the safety device 13 mounted at the upper end of the J-shaped box 10 has the role of detecting a storage of the fabric at too high a level in the box 10, which would be a sign of unsuitable speed of movement in storage compartment 4, ascent.
  • the safety device 13 can be constituted, for example, by a funnel which can pivot around a horizontal axis, in the event of detection of a storage which is too high, to trigger a contactor which stops the take-up roller 6, 7, 9 or the like and, if necessary, can reverse the operating direction thereof until the storage has reached, in the box 10, a lower level compatible with the requirements of the operation of the machine, l 'funnel 13 then resumes its rest position and releasing the trip switch.
  • Another security device is associated with the storage compartment; it may be constituted, for example, by a pivoting wall 14, the pivoting of which is caused by too great advancement of the fabric in the compartment, in the vicinity of the ascent of the fabric, to an extent likely to cause interference with the pleated fabric 11 emerging from the J-shaped box 10 (see Figure 7) or with the box 10 itself (see Figure 4).
