Definitions

  • the invention relates to a method for taking up a strand of fibrous material or twist yarn having little or no cohesion downstream of a wet treatment station for said material.
  • the traction members very quickly become clogged with the deposit of glue which is made therein continuously.
  • the object of the present invention is to provide a method for recovering the wick free from the aforementioned drawbacks.
  • the pneumatic torsion-traction means are used, which by its air jet "pushes" the wick with a certain power, to pro throw the wick on a transfer device to a downstream treatment station, such as a drying station.
  • the invention allows automatic threading at the start of spinning and, on the other hand, results in less electrical energy consumption than with two separate means for traction and torsion.
  • the invention also relates to a wick take-up system applying the method of the invention and comprising a single pneumatic means for twisting and pulling said wick being constituted by a duct for passing the wick into which a tangential compressed air supply opens. with respect to said conduit and substantially inclined with respect to the direction of advance thereof.
  • the duct can be drilled in a block, the upper part of which is optionally provided with two gutters joining a water supply point, drop by drop, respectively at the inlet and at the outlet of the scroll duct, at self-cleaning purposes if necessary.
  • the invention relates to an installation comprising a wet treatment station for fibrous material followed by the wicking recovery system.
  • Figure 1 schematically shows an installation with the wicking take-up system 1 according to the invention, downstream of a wet treatment station 2. It is in fact a wire called wick since it has no twist: it is a stretched wick having the characteristics of title (or linear mass) of a wire.
  • This wet treatment station 2 can for example be a station for gluing the wick, ending at its downstream section by two expressing cylinders 3.
  • a drying station 5 of the wick Downstream of the recovery system is located a drying station 5 of the wick, which the wick to be dried crosses by means of a conveyor belt 6. At the exit of the drying station, a winder not depicted receives the dried wick.
  • the recovery system 1 comprises a block 7 pierced with a rectilinear scroll duct 8.
  • the block 7 is of any external shape, for example parallelepiped, and can be made of a transparent plastic material.
  • the passage duct 8 opens a compressed air inlet 9 (connected to a source not shown), the orientation of which is such as to impart a twist to the wick and to make it pass.
  • the inlet 9, located in a plane parallel to the conduit 8, opens tangentially with respect to said conduit 8 ( Figure 4) and is inclined relative to the direction of the axis (arrows 10, fig.3) of the wick in the passage duct 8 at an angle a advantageously between 120 and 155 ° C, depending on the nature of the fiber, the fineness of the thread, the nature of the adhesive, taking into account the tension necessary for "tear off" the wire, and the inclination of the receiving mat in relation to the axis of the jet.
  • the compressed air consumption at around 1 bar was of the order of a few liters per minute.
  • the ratio of the length of the duct to its diameter is between 2 and 50, and preferably between 4 and 20, for diameter values between 0.5 and 6 mm depending on the yarns to be produced, and preferably between 1 to 3 mm.
  • the ratio between the diameter of the conduit and that of the yarn is advantageously between 1.5 and 8 (taking into account, however, the imprecision on the diameter of the yarn in its state under low tension and relatively strong twist).
  • the ratio of the diameter of the passage duct to that of the nozzle is advantageously between 1 and 5, and preferably between 1.4 and 3, with the search for the minimum flow rate sufficient to obtain the traction effect.
  • the wick 13 leaving the wet treatment station 2 is therefore twisted and simultaneously pulled under the wrapping effect of the helical air current produced by the inlet 9. Still under the effect of this helical air current, the wick 13 ', coming out of block 7, is expelled from it with a certain force.
  • the wick 13 ' By having receiving means such as the conveyor belt 6 substantially on the path of the wick 13 ', the latter is projected there and remarkably forms non-regular turns 14 but generally fairly homogeneous in their dimensions. This projection, which is done without the assistance of mechanical organs allows a deposit without constraint, so that the yarn will be able to be released from all internal tensions (shrink freely) during drying.
  • the mat 6 made of a material of low adhesion, for example in a glass mesh "teflon"; leads the wick to a drying station 5. Drying gives the wick all its cohesion and then allows reeling to be done normally.
  • a self-cleaning device which can comprise two gutters 15 hollowed out on the upper part of the block 7 and joining an upper point of water supply 16 to the drip respectively at the inlet 17 and at the outlet 11 of the scroll duct 8. It can be provided , as shown, a single upper gutter 15 which distributes the water towards the inlet 17 and the outlet 11 of the scrolling duct, aided in this by two intermediate inlet and outlet gutters 19.
  • the shape and position of the gutters take account of the shape and position of the block 7, which is not necessarily horizontal as shown, but can be tilted, in a manner compatible however with the projection which must be carried out.
  • the gutters are designed so as to distribute the water between the inlet and the outlet of the channel so as to maintain a concentration of material therein sufficiently low to prevent its deposition and to promote its entrainment with the wick.
