Definitions

  • the present invention relates to a method for treating a moving wire, and more particularly a method of cooling the wire after passing through an oven during a texturing operation, in particular by false twisting.
  • the present invention applies to all types of monofilament or multifilament yarns, even a procession of fibers.
  • the method according to the invention making it possible to cool a wire in motion at the outlet of an oven before passing through a processing member such as a false twist pin, consists in passing said wire through the inside a tube traversed by a stream of fresh air or other gaseous product, said stream of air being directed in a direction opposite to the direction of passage of the wire, and it is characterized in that during this cooling phase , the wire is kept in contact with a bearing or guiding surface arranged coaxially inside the tube through which the air stream which flows along said guiding surface passes.
  • the outer tube is of cylindrical section and the coaxial guide surface is itself constituted by a cylindrical element, the air stream flowing along said surface in the space between said tube.
  • the material making it possible to produce the guide surface any material having mechanical characteristics such that it resists abrasion will be used, without altering the properties of the wire, such as for example ceramic. It is however advantageous to use a material which also has, in addition to the above characteristics, that of also being a good thermal conductor, which further improves the cooling process; such a material can for example consist of stainless steel having received a surface treatment (plasma, etc.).
  • the passage of the wire against the guide surface is carried out so that it forms a helix around the latter; advantageously, the wire surrounds said guide surface over 180 ° between its entry and its exit from the cooling zone.
  • the guide of the wire is advantageously obtained by making the connection between the guide surface and the outer tube by means of "pins" arranged at the ends of the assembly and offset angularly one with respect to the other.
  • the outer tube also has a longitudinal slot facilitating the introduction of the wire; such an embodiment makes it possible to automatically obtain a positioning of the propeller against the surface disposed inside the outer tube.
  • the invention also relates to an installation implementing such a method.
  • cooling means consist of an assembly comprising a tube traversed by a stream of fresh air or other gaseous product, directed in the opposite direction to the direction of passage of the wire and inside which is disposed. , coaxially, a bearing surface for said wire.
  • said guide or support surface is in the form of a rectilinear block, of cylindrical cross section, and outside of which comes to bear the wire during its displacement.
  • the path of the wire against the guide surface is produced by forming a helix between the inlet and the outlet of the cooling assembly; in this embodiment, the guiding of the helical wire is obtained by providing, at least one inlet and one outlet for the cooling assembly of the "pins" connecting the internal cylindrical surface to the external surface, and which are angularly offset with respect to each other, such elements making it possible not only to ensure the automatic positioning of the wire inside the cooling assembly, but also the connection between the external envelope and the core ( guide surface) internal.
  • Such a cooling assembly is aligned with the outlet of the oven and the false twist spindle, and can be arranged in any position, either horizontally or slightly inclined downward in the direction of movement of the wire, either vertically or making any angle to the vertical.
  • a second fixing oven can be provided between the last call (8) and the winding system (3).
  • the cooling zone produced in accordance with the invention consists essentially of an assembly (6) arranged in the extension and near the outlet of the oven (5), and preferably aligned with the false twist pin (7) to obtain a substantially straight path of the wire.
  • This cooling assembly is constituted by a tube (10), preferably of cylindrical section, and which has a slot allowing the positioning of the wire (2) during the launching operation. Inside this tube (10) is arranged, coaxially, a cylindrical guide surface (9) based on any suitable material, such as in particular ceramic, or stainless steel having received a surface treatment such as for example a plasma treatment.
  • such an assembly (6) has a length of 300 millimeters, a diameter for the outer tube (10) of 25 millimeters, and a diameter for the cylindrical guide surface (9) of 15 millimeters.
  • Additional guide means (11,12) for the wire (2) are preferably provided upstream and downstream of the cooling assembly (6) and allow the wire (2) to follow a path in the form of propeller against the surface (9).
  • a path in the form of a helix is obtained by using as guide means (11,12) two "pins" disposed at each end of the assembly (6), and which are offset angularly one in relation to the other.
  • a slot is provided to facilitate threading of the wire.
  • the outlet of the assembly (6) there opens a conduit (13) connected to a source of compressed air, making it possible to breathe into the space between the core (9) and the outer casing (10), a current of air flowing in a direction opposite to that of the advance of the wire (2) and producing a venturi effect inside said assembly.
  • the air pressure blown inside the cooling assembly is generally low and of the order of one (1) bar, the flow rate being significant taking into account the fact that there is an additional call.
  • the air flow can be regulated by any appropriate means and depends on the nature of the wire, temperature and its speed.
  • the air supply can be carried out either individually for each position of the machine, or by means of a common supply for all positions.
  • the air cools the thread in the opposite direction and therefore breaks the hot air sheath which surrounds it, the cooling being moreover accentuated by contact with the guide surface.
  • wire which, in summary, provides cooling combining both an extraction of calories by convection and conduction.
  • the guide surface (9) against which the wire rests during its passage inside the cooling assembly not only promotes its cooling, but also eliminates any risk of disturbances or faults created by the air flowing inside the cooling assembly.
  • the outer split tube not only allows air to be channeled, but also causes a venturi effect resulting in a large natural flow, making it possible to remove the hot air sheath which accompanies the wire.
  • the treatment organs are arranged horizontally, but it could be envisaged to arrange them vertically or by using any angle relative to the vertical.
