  • the new beginning of the thread formed in this way should be grasped and anchored by a catching area of an empty winding tube, which is located on the other winding spindle, which is in the winding position. This is followed by a new winding on the new winding tube.
  • the severing of the thread can be carried out by tearing as a result of an increase in the thread tension and / or by means of a cutting device.
  • the catching area can be arranged on the respective winding tube within the laying width or outside the laying width.
  • the catching area can in this case be designed, for example, as one or more incisions arranged distributed over the circumference of the winding tube or else also by means of a hooked strip strip. It is also possible that the catching area is formed by the winding spindle and thus independently of the winding tube.
  • WO 2003/099695 A1 also describes the fixing of a thread on a winding tube by means of a fixing winding.
  • a fixing winding is understood to be a bead-like winding of the thread, in which the thread layers are in a narrow axial region of the winding tube, either at a distance from the winding tube, ie outside a laying width, or in the region of the laying width, close to each other and / or one above the other be wound to fix the beginning of the thread on the winding tube.

  • WO 2003/099695 A1 proposes a method for operating the winder, in which the spatial position of the traversing yarn guide of the traversing unit is detected. The detected spatial position is fed to a control unit of the winding machine at any time or calculated in the control unit.

  • the incoming thread should be wound without significant interruption to coils.
  • the winding spindle with the finished wound coil moves into the change position, on the one hand to make a transfer of the thread to the guided into the winding position new winding spindle and on the other hand to allow the decrease of the finished wound coil of the winding spindle held in the change position.
  • the end of the thread produced during the transfer of the thread is usually deposited on the circumference of the finished wound coil held in the change position.
  • DE 10 2008 062 161 B3 is devoted to the problem that a loose end of the thread of a finished wound spool is accelerated radially outward even while in the alternating position rotating coil, which is basically undesirable.
  • the loose end of the thread of the full bobbin, which is in the change position can be caught by an empty bobbin in the winding position or any catching device, thus disturbing the beginning of the winding process of the next bobbin, which is in the winding position.
  • DE 10 2008 062 161 B3 suggests the use of a separating device which provides a partition between the coils which are arranged in the region between the winding position and the changing position.
  • the partition wall of the separation device is intended to block the passage of the loose end of the thread from the spool in the area of the change position to the spool in the area of the winding position.
  • EP 1 627 840 A1 is concerned with the securing of the free end of a wound into a coil yarn, in which case the coil is formed as a yarn package, bobbin or cocoon, which are used for creating embroidery by means of embroidery machines or stitching by means of quilting machines.
  • the beginning of the yarn extends from the inside of the winding.
  • a yarn package is inserted into a shuttle of the embroidery machine or quilting machine, in which case the outwardly extending beginning of the yarn is pulled through different loops of the shuttle.
  • the free, outboard end of the yarn is usually wrapped ("underwrapped") under a previous turn of yarn and then cut short.
  • EP 1 627 840 A1 proposes to secure the free end of the yarn cohesively, in particular by means of gluing or welding in the case of a fusible yarn, to the outer circumferential surface of the yarn package.
  • the yarn is withdrawn from the yarn package starting with the inside yarn.
  • the yarn is taken from radially inward to radially outward of the coil with increasing migration of the inner circumferential surface of the yarn package to the outside.
  • GB 454 555 B suggests, however, to fasten the free end of a thread on the outer surface of a winding by means of a tack nail.

  • a switch in the stepless groove portion allows the traversing yarn guide in conjunction with a renewed reversal of direction to reach the laying channel for the purpose of building the coil on the bobbin.
  • bobbin tubes are used which have a catching area.

  • the receptacle 22a, 22b may also be formed as an L-shaped bracket, wherein a leg of the L from the guide rod 21a, 21b extends radially outwardly, while the other leg of the L parallel to the longitudinal axis of the guide rod 21a, 21b extends (namely, extends away from the catcher 23 for catching the Spulguts 3 on an empty winding spindle away).
  • the winding of the coil 2 on the winding spindle 8a is in one of Fig. 3 deviating position takes place, for example, in a 12 o'clock position of the winding spindle 8a on the revolver 19 (winding position).
  • Fig. 3 and 4 show the winder 1 during rotation of the turret 19 in a clockwise direction from the winding position to the change position.
  • This rotation causes the Spulgut 3 with the holding and / or guiding device 20a, 20b interacts, namely, applies to the lateral surface of the guide rod 21a, 21b, wherein the circumferential angle of the system of Spulguts 3 to the lateral surface of the guide rod 21a , 21b increases with increasing rotation of the revolver 19.
  • the winding spindle 8b If, at the end of the rotation of the turret 19, the winding spindle 8b is in the winding position, while the winding spindle 8a with the bobbin 2 arranged thereon is in the change position, the winding material 3 must be brought into interaction with a catching device 23b, which in the embodiment shown in FIG Axial Scheme of the winding spindle 8 b or the bobbin tube 9 b is arranged, which is arranged on the side facing away from the turret 19 in front of the laying width and in front of the winding 10.
  • the Spulgut traverse guide 12 is moved in an axial area outside the laying width.
  • This movement of the Spulgut-traversing yarn guide 12 causes the angle of the Spulguts between the Spulgut-Changier proceedingss 12 and the receptacle 22b of the holding and / or guiding device 20b changed while the position and orientation of the Spulguts 3 between the receptacle 22b and the Spool 2 does not change. In this way it can be ensured that (in spite of the movement of the package traverse guide 12), the loose end 17 of the Spulguts 3 is not "pulled out” from the gap 16 between the rings 13, 14.
  • the axial movement of the winding material traversing yarn guide 12 causes the winding material 3 to be deflected in the region of the radially oriented leg of the L. If the winding material 3 is then caught by the catching device 23b in the area of the empty winding spindle 8b, the winding cycle can begin on this winding spindle 8b.
  • a severing of the Spulguts 3 is carried out by a separate separator. It is also possible that a cutting of the Spulguts 3 in the region of the holding and / or guiding device 20 takes place, for which purpose a separate separating device may be present. It is also possible that by means of an increase in the tension in the winding material 3 a severing in the region of the holding and / or guiding device 20, possibly at a corresponding cutting edge thereof, is brought about.
  • Fig. 5 shows in detail the securing of the end 17 of the Spulguts 3 to the coil 2:
  • the Spulgut 3 is wound to the rings 13, 14, which have a distance 15.

  • the partial rings 24, 25 are produced with directly adjoining, successively wound portions of the Spulguts 3.
  • the ring 14 is not formed with different, mutually offset partial rings. Rather, here all layers of the ring 14 are wound directly without offset each other.
  • the thickness D 14 of the ring 14 is slightly smaller than the thickness D 24 of the partial ring 24 of the ring 13.
  • the space 16 between the rings 13, 14 is axially limited by an axial end face 27 of the ring 14 and an axial end face 28 of the ring 13.
  • the axial end face 27 of the ring 14 is formed in the form of a circular ring surface, which is radially inwardly adjacent to the lateral surface 11 of the winding 10.
  • the axial end face 28 is formed as a result of the offset 26 with a peripheral step 29.

  • this side leg is longer than the rectilinear side legs of U. formed by the face 27 of the ring 14.
  • the end 17 of the Spulguts 3 is inserted, inserted or retracted. Since the distance 15 of the end face 27 of the ring 14 from the annular surface formed by the partial ring 24 of the axial end face 28 of the ring 13 is smaller than the width B 18 of the Spulguts 3, the Spulgut 3 is supported with its end faces on the end faces 27, 28th of the rings 13, 14 from.
  • the end 17 of the Spulguts 3 is elastically clamped between the end faces 27, 28, which results in an axial contact force between the end 17 of the Spulguts 3 and the end faces 27, 28.
  • the axial contact force leads to a frictional force between the end 17 of the Spulguts 3 and the end faces 27, 28. This frictional force forms a resistance to an outlet of the end 17 of the Spulguts 3 from the gap 16.
  • the step 29 of the end face 28 is a positive obstacle against an exit of the end 17 of the Spulguts 3 from the gap 16.

  • Fig. 6 shows an alternative embodiment, in which not only the ring 13 is formed with partial rings 24, 25, but also the ring 14 is formed with partial rings 30, 31.
  • the outer partial ring 31 is arranged with an offset V 32 in the direction of the other ring 13 with respect to the inner partial ring 30, so that now also the end face 27 has a peripheral step 33.
  • intermediate space 16 is in particular a bending elasticity of the cross section of the Spulguts 3 to a bending axis, which is oriented in the longitudinal direction of the Spulguts exploited.
  • this can be utilized by generating a kind of folding or bending of the cross section of the material to be wound 3 about the said bending axis, whereby the insertion of the end 17 into the narrowed space 16 is made possible in the first place.
  • a winding spindle 8a is converted into a winding position by turning the revolver 19.
  • a subsequent method step 35 if necessary by moving the traversing unit 7, the winding material 3 is brought into interaction with a catching device 23a of the winding spindle 8a or a bobbin tube 9a arranged thereon, thus fixing the winding material 3 to the winding spindle 8a or the bobbin tube 9a.
  • a process step 36 is carried out by performing a traverse of the winding material traverse guide 12 of the traversing unit 7 within the laying width, a winding of the winding 10.
  • winding of the ring 13 takes place in a method step 37, which is preferably the ring which is arranged adjacent to an end face of the coil 7, in the region in which the winding 10 ends.
  • the movement of the winding material traversing yarn guide 12 on the traversing unit 7 takes place in an axial position which corresponds to the position of the ring 13.
  • the winding material traversing guide 12 is moved away from the end face of the coil 2 by the offset V 26.
  • the thicknesses D 13 and D 24 , D 25 are controlled by the length of the supplied Spulguts or the number of revolutions of the winding spindle 8 and the coil 2. If the ring 13 completely wound, is in a Method step 38 of the winding material traversing guide 12 moves axially away from said end side of the coil 2 so that the distance 15 results.
  • the ring 14 is then wound in a method step 39, wherein, in the event that two partial rings 30, 31 are to be wound, after completion of the inner partial ring 30, the package traverse guide 12 is moved back again by the offset V 32.
  • the Spulgut-traversing 12 is then moved centrally between the two rings 13, 14 in a process step 40, which leads in view of the tension of the Spulguts 3 that the Spulgut on the edges of the tops of the two rings 13, 14 applies, the Spulgut 3 bends in cross-section radially inwardly and the Spulgut 3 can enter into the gap 16 between the end faces 27, 28 of the rings 13, 14, where this is spread apart again due to the elasticity of the Spulguts 3.
  • the Spulgut 3 and the end 17 is held at an axial position such that the end 17 is not pulled laterally or upwardly from the gap 16 between the rings 13, 14.
  • the further rotation of the turret 19 in a process step 43 with the simultaneous movement of the winding material traverse guide 12 has the consequence that upstream of the receptacle 22 a, the Spulgut 3 in Interaction with the catcher 23b of the winding spindle 8b or bobbin 9b occurs.

  • the illustrated embodiments are not intended to limit the invention. So it is quite possible that the rings 13, 14 and the partial rings 24, 25, 30, 31 have a greater width than shown, so that quite a winding of the rings 13, 14 can be carried out with a reciprocating motion of the traversing unit 7 , It is also possible that several turns of the end 17 of the Spulguts 3 are introduced into the gap 16.
  • the formation of the rings 13, 14 may differ from the illustrated embodiments. Thus, more than two partial rings may be provided one above the other in a ring 13, 14.
