Definitions

  • the present invention relates to a device for winding a ribbon of textile fibers 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 been subjected upstream a slight false twist tending to reinforce to a certain extent the latter two properties; such is the case for example of a fiber ribbon which is obtained at the outlet of a drawing machine, the ribbon being delivered through an outlet guide which gives it this slight false twist and which directs it towards the device winding.
  • This ribbon being mechanically fragile and liable to deteriorate in the event of excessive mechanical stress, we have hitherto used, to start the winding on a winding mandrel, a movable folding device whose role was, at the beginning of the winding, press the front end of the ribbon around the mandrel so that this end is securely fixed on the latter and that the formation of the coil can, in principle, start and continue correctly.
  • this solution has various drawbacks: if the reel has not properly fulfilled its function, the start of the winding is defective and all the corresponding material is lost, which represents a loss of material and a reduction in the efficiency of the machine, with the ensuing economic repercussions; it sometimes happens that the reel member performs a bad winding for the first turns, these being for example badly distributed or tangled in a single area, with the consequence that either the first turns are lost, or, if the winding continues , the coil is badly wound, with the drawbacks which result from it during the subsequent use of the coil; it sometimes happens that untimely windings occur between the take-up cylinder and the mandrel, this take-up cylinder being close to the mandrel and guiding the ribbon towards it; the folding member constitutes a controlled mechanical part and it is therefore susceptible to breakdowns and malfunction, in addition to the fact that alone, with its means of order, it contributes significantly to the cost price of the winding device.
  • the object of the invention is to remedy these drawbacks by providing a winding device of the type indicated above which does not use a folding device, while ensuring particularly reliable winding of the ribbon.
  • the device according to the invention is characterized in that the zone of cooperation or convergence of the mandrel and of the take-up cylinder is located in the vicinity of the outlet of said guide to receive the ribbon directly and that the peripheral surface of the mandrel exhibits at least locally gripping properties with respect to the ribbon.
  • the mandrel carries hooking elements which can be constituted, for example, by at least one longitudinal strip of teeth, in particular of the card lining type, at least one rough, adherent, hanging or asperity strip reported on 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, it is possible to provide three bands of teeth arranged at 120 °.
  • the gripping properties of the mandrel with respect to the fiber ribbon can also be imparted by the surface condition of said peripheral surface itself.
  • the means giving the peripheral surface of the mandrel these hooking properties are slightly protruding outwardly relative to this surface.
  • 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.
  • the above device can advantageously be supplemented by 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.
  • pneumatic means for example a nozzle
  • 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 rotation movement, continuous or alternative, about 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 the 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 7 in which the ribbon passes 2.
  • the outlet guide 1 is arranged in the vicinity of the zone 7 of 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 deflects it slightly towards the mandrel 4.
  • the peripheral surface 8 of the mandrel 4 has at least locally gripping properties with respect to the ribbon 2 to hang 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 gripping 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.
  • This local longitudinal limitation of the hooking properties is intended to prevent an excessive 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 strips 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 peripheral surface 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.
  • the above device can advantageously be supplemented by pneumatic means (not shown), for example a nozzle projecting compressed air, for pressing 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, to reinforce the attachment action of the mandrel 4 with respect to the fiber ribbon 2.
  • pneumatic means for example a nozzle projecting compressed air, for pressing 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, to reinforce the attachment action of the mandrel 4 with respect to the fiber ribbon 2.
  • the device according to the invention is particularly simple, economical and reliable, thanks in particular to the fact that the folding member is eliminated, the drawbacks of which have been indicated above, and thanks to the fact that the ribbon 2 is directly supported by the mandrel 4 which is arranged to hook itself the front end of the ribbon.
