Definitions

  • the present invention relates to an arrangement for winding a textile fiber ribbon in the form of a reel, in particular in the case where this ribbon has relatively low cohesion and mechanical strength even if it has undergone upstream a slight false twist tending to reinforce to a certain extent these last two properties; such is the case for example of a fiber ribbon which is obtained at the exit of a drawing machine, the ribbon being delivered through an exit guide which gives it this slight false twist and which directs it towards the device winding.
  • the object of the invention is to remedy these drawbacks by providing an arrangement for the winding of the type indicated above which does not use a folding device, while ensuring a particularly reliable winding of the ribbon.
  • Document GB-A- 1.341.034 discloses a winding device in which a winding mandrel is rotated by a winding cylinder, a cursor moving along the mandrel in an alternating movement to distribute a wire in turns. over the entire length of the mandrel.
  • Such a device cannot be used with a textile fiber ribbon, by nature very mechanically fragile, because the yarn of this document of the prior art is subjected to very intense mechanical stresses which a ribbon cannot undergo. without deteriorating and breaking.
  • Document FR-A-2,217,252 also discloses a wire winding mandrel which, for retaining the wire at the start of the winding, has on a part of its surface a rough lining constituted by a hook tape, replacing the previous fittings (notches, hooks, roughness, bristles, adhesive, etc.).
  • Document FR-A-2,354,024 also discloses a mandrel for winding a wire or a wick, the external surface of which has a plurality of grooves, for example axial, with sharp edges.
  • the arrangement according to the invention for the winding in reel of a ribbon or wick of textile fibers of low cohesion and mechanical strength on a rotating mandrel animated by an alternating axial movement, the peripheral surface of which has at least locally gripping properties with respect to the ribbon and which cooperates for the winding with a winding cylinder defining with the mandrel a zone of cooperation and convergence for the reception of the ribbon and its guidance towards the mandrel, a guide, rotating around its axis, being provided to apply a false twist to the ribbon before it is wound, is characterized in that the guide is located in the vicinity of said cooperation and convergence zone so that the ribbon passes directly from the guide to said zone.
  • the mandrel carries hooking elements which are constituted by at least one longitudinal strip of teeth, in particular of the card lining type, and at least one rough, adherent, hanging or asperity strip attached to said peripheral surface; in the case of at least one strip of teeth, this is housed in a longitudinal groove of the mandrel; for example, one can provide three bands of teeth arranged at 120 °.
  • the gripping properties of the peripheral surface of the mandrel are present at least in the longitudinal arrival area of this front end of the ribbon.
  • pneumatic means for example a nozzle, for pressing the front end of the strip against the mandrel and thus enhancing the effect of the hooking properties of the peripheral surface of the latter.
  • FIG. 1 Schematically and partially shown in section in FIG. 1 a guide 1 for a ribbon or wick 2 of textile fibers, this guide being, in the preferred application of the invention, an outlet guide for a spinning preparation machine, for example a drawing bench, this guide 1 being driven in a rotary movement, continuous or alternative, around its longitudinal axis 3 to give the ribbon 2 a slight false twist at the exit, reinforcing its cohesion and its mechanical strength.
  • This fiber ribbon 2 is intended to be wound or wound on a mandrel 4 driven in continuous rotation about its longitudinal axis 5, this rotation being indicated by arrow A and being accompanied by an alternating axial displacement, as shown by the double arrow B (Fig. 2), to distribute the ribbon turns axially over the entire length of the mandrel 4.
  • the mandrel 4 cooperates with a cylinder 6, called the winding cylinder, which rotates in the opposite direction to the mandrel 4, as shown by the arrow C, this winding cylinder being practically tangent to the mandrel 4, leaving a small space with it. constitutes the zone 7 of cooperation and convergence between the mandrel 4 and the winding cylinder 6, through which the ribbon 2 passes.
  • a cylinder 6 called the winding cylinder
  • the outlet guide 1 is arranged in the vicinity of the area 7 for cooperation between the mandrel 4 and the take-up cylinder 6, and its longitudinal axis 3 is substantially tangent thereto.
  • the ribbon 2 comes out substantially in a straight line from the guide 1, along the longitudinal axis 3 of the latter, to reach directly in the zone 7.
  • the axis 3 is in fact not exactly tangent to the mandrel 4 and to the winding cylinder 6, but it is arranged in such a way that the ribbon 2 comes first to cooperate with the winding cylinder 6 which takes it in and slightly deflects it towards the mandrel 4.
  • the peripheral surface 8 of the mandrel 4 has at least locally gripping properties with respect to the ribbon 2 in order to hook the front or upstream end 9 of the fiber ribbon 2 and thus cause the beginning of the winding or winding without the use is made of the folding device of the prior art previously discussed.
  • these gripping properties, at least locally, of the peripheral surface 8 of the mandrel 4 can be obtained in various ways; for example, these hooking properties can be imparted by the surface condition of this peripheral surface 8 itself which will have undergone a mechanical or chemical treatment giving it, for example, a high roughness. It is also possible to use a rough strip which is attached to the peripheral surface 8 and which itself exhibits these hooking properties, for example being rough or adherent.
  • the fastening elements are in slight radial projection towards the outside relative to the surface 8, so as not to cause a local excess thickness of the turns during winding.
  • the gripping properties of the peripheral surface 8 of the mandrel 4 are only present over part of the length of this surface.
  • the zone in which these hooking properties exist is then that on which the front end 9 of the ribbon 2 arrives.
  • the purpose of this local longitudinal limitation of the hooking properties is to prevent too long a length of the ribbon 2 from being hooked and allow the subsequent unwinding of the mandrel 4 that only a short length of the tape 2 remains attached to the mandrel 4 and therefore risks being lost.
  • the gripping properties of the peripheral surface 8 of the mandrel 4 are imparted by hooking elements which are in the form of at least one longitudinal strip. 10 of teeth 11, this strip being of the card lining type, the teeth 11 being for example metallic, To avoid excessive projection of the teeth 11, the strip 10 is housed in a longitudinal groove 12 of the mandrel 4.
  • three bands 10 can be provided, arranged at 120 °.
  • the front end 9 of the fiber ribbon 2, at the outlet of the guide 1, first reaches the peripheral surface of the take-up cylinder 6, then in the area 7 of cooperation between the mandrel 4 and the take-up cylinder 6 , to be quickly grasped by the surface peripheral 8 of the mandrel 4, thanks to the hanging properties described above of this surface 8, which causes the beginning of the winding of the ribbon 2 on the mandrel 4.
  • pneumatic means for example a nozzle projecting compressed air, to press the front end 9 of the ribbon 2 against the mandrel 4, before or after the zone. 7, or even in the zone 7 itself, in order to reinforce the attachment action of the mandrel 4 with respect to the fiber ribbon 2.
