Description

The subject of the invention is a machine for the wet treatment of articles

textiles, in particular in the form of

  gut-pieces or made-up articles.

  It is known that the wet treatment (dyeing and / or bleaching and / or washing and / or finishing, etc.) of textile casing parts, that is to say pieces of fabric or knit or products analogous in strips of great length (several hundred meters) can be carried out by carrying out various processes which differ from each other mainly in that the articles to be treated are immobile and the treatment fluid circulated, or the reverse . To these processes correspond various types of processing machines, some of which comprise a tube in which the tissue circulates by being caused by bath overflow in a tube inlet funnel, -System known as "overfloW", or under the action of the treatment fluid sprayed into a nozzle

  opening into the tube, -system called "jet" -.

  Whatever machine is used, it is always

  days intended for the treatment of parts-hoses, and parts-hoses only, so that the finishing facilities textile materials which, as is frequently the case, have to treat different products concurrently to parts-casings ,, for example wire in coils, or wad, or fabrics in beams, or skeins must be equipped with different machines which, of course, are not used when the installation deals, at a given moment, a type of

  product and not the others, thereby increasing the immo-

  the financial costs and, therefore, the economic costs of treatment. The same applies to the wet treatment of made-up textile articles, which generally takes place in specific machines reserved for

this only use.

  A first general problem therefore arises of trying to increase the profitability of a wet processing plant for textile articles, in particular by reducing the type of machines in the plant or, in other words In other words, by providing a versatile machine and thus capable of being used for the wet treatment of textile articles differing from one another in their presentation but also in their nature. In this regard, there is also a second problem, namely that of providing a machine for the wet treatment of textile materials of different natures, for example natural fibers or synthetic fibers, or even fibers.

  synthetics of different chemical compositions.

  It is, therefore, a general object of the invention

  to provide a wet-processing machine parts-

  hoses, which can also be used for the treatment of other textile products as varied as bobbin yarn, wad, skeins, fabric bundles, etc .... and, also, made-up articles that these are in materials & warp and weft, -or &

mesh, etc ...

  It is still an object of the invention to provide such a machine which allows the wet treatment under variable conditions of use, for example with or without pressure, as required for the treatment of certain

fibers and not for others.

  It is also an object of the invention to provide such a wet treatment machine which, although suitable for pressure treatment, is however of relatively simple construction, of small footprint and,

thus, easy operation.

  In order to solve the problems mentioned above on the one hand, and to achieve the goals defined above, on the other hand, the invention applies the work of the Applicant in the field of wet-processing facilities for textile materials and, in particular, machines equipping an installation as described in its Application EP-A-0O

  Referring first to Figures 1 to 3 which illustrate the general structure of a machine for the wet treatment of textile materials as implemented by the invention. It comprises a vessel 10 having a substantially horizontal longitudinal axis and which rests directly on a base 20 on the floor S of a wet treatment plant such as a dyeing plant or the like, without this indication being, of course, of any limiting nature. is. The tank 10 is provided at one of its longitudinal ends with a door 11 equipped with portholes 17, advantageously of the type & pivoting about a vertical axis aLp and, at its other end, a front wall 12. As visible in FIG. 3, the tank is advantageously parallelepipedal and limited by lateral vertical walls 13, 14, a floor 15 and a flat roof 16. Transverse stiffeners and longitudinal reinforcements, not shown, are provided where appropriate. To the tank 10 is associated an apparatus 36 for moving the treatment fluid in said tank, for example a dye bath, said apparatus comprising a pump or turbine 37 driven by a motor 37A and a suction pipe 38 or discharge pipe and a discharge pipe 39 or suction, respectively. On one and / or the other of said pipes, here the pipe 39, is provided a heat exchanger 40, the two pipes 38 and 39, in which the treatment fluid circulates in a closed loop circuit, being connected to the volume inside the tank 10 o are

  housed the materials to be treated. In the realization

  38, the tubing 38 is in the form of a pair of breeches from which two branches 411 and 41m result which lead to passages 42 and 43 formed in the front wall 12 of the tank 10 while the tubing 39 reaches a passage 44.

  also formed in said wall, in the form of a

  the largest dimension is directed

  perpendicular to the axis of said vessel.

  For the treatment of PB hoses, the tank 10 is associated with a PM carrier, FIGS. 4 and 5, consisting of

  by a box 50 of parallelepipedal general shape con-

  Juguée that of the tank and which is, thus, limited externally by: * longitudinal walls 51 and 52 whose distance is very slightly less than that separating the walls 13 and 14 of the tank 10; a flat bottom 53 adapted to cooperate with rollers r mounted on the bottom 15 of the tank 10 and which is pierced with an opening 54 with which is associated a valve 54 '; a transverse wall 55, hereinafter referred to as the front wall, since it is close to the door 11 of the tank when the material carrier PN is introduced into the latter, and which is provided with perforations 85 in its lower part oblique with respect to the bottom 53; and e a bath distribution box, 56, which forms the "posterior" end of the box 50 since said distribution box is close to the wall 12 in the operating condition of the installation. As

  shown schematically in FIG. 4, the distribution box

  In the lower part, the bathing unit 56 comprises coupling means 57 and conjugate means 58 associated with the passage 44, so that the fluid or treatment liquid set in motion in the tubing 39 by the pump or turbine 37 may be introduced. and / or extracted from the box 50 via the distribution box

  56 and means 57 associated therewith.

  In the embodiment described and shown in FIG. 5, the box 50 is divided longitudinally by partitions 60 and 60z delimiting compartments or

  61, 61m, 61L processing channels, each, of a part-

  PB, PB2, PB3, respectively. In each of the channels or compartments 61, and in the vicinity of the anterior wall, is mounted on the same shaft 62 a call roller 63, adapted to be driven by a motor 64 outside & the tank 10 via a clutch 65 cooperating with the shaft 62 and disposed partly and -in the outside and for

  part inside the tank 10.

  In each of the compartments or channels 61 is also

  a tube 70 of relatively fast circulation of

  the hose-piece PB, whose input is a device 72 'to

  trapping of the bath by overflow, or "overfloW" and on which is arranged a jet device 71, the output 73 of the

  tube 70 in the form of an inverted funnel delivering the

  PB casing in the treatment bath volume V where it moves more slowly than in the tube 70 forming

  more or less loose convolutions.

  As shown in FIG. 4, means referenced schematically at 75 enable the adjustment of each Jet device 71 while referenced means 76 allow the adjustment of the overflow devices 72, the control of the means 75 and 76 being carried out at the outside the tank by assemblies respectively shown at 77 and 78 and with control circuits 79 and 80 which pass through the wall of the tank 10 via

  glands 81 and 82, respectively.

  The operation of a machine according to the invention for the treatment of parts-hoses results immediately from this

who is before.

  In a first step, the box 50 is introduced into the tank 10, most simply by rolling it over the rollers or rollers until the means 57 are brought into contact with the means 58 which, simultaneously, ensure the positioning of the shaft 62 opposite the clutch 65 on the one hand while the connections of the circuits 79 and 80 are made to the adjustment members 75 and 76, and a control 54 "of the valve 54 'after closing the door 11. The treatment fluid, for example water for loading the materials to be treated is then

  set in motion by the apparatus 36 to circulate

  an endless loop made from the tubing 39, the passage 44, the distribution box 56, the tube 70, the volume V, the perforations 85 of the lower part of the front wall 55, the return of the bath to the apparatus 36 taking place by the space between the tank 10 and the body 50 and, from this space, by the passages

  42 and 43 to the branches 41, and 41z of the tubing 38.

  Alternatively, and / or additionally, the return of the bath takes place through the opening 54 and the valve 54 '

  controlled from outside the tank 10 by the control organ
