Definitions

  • the invention relates to a method for forming a curl-free thread reserve and a winding machine for winding one or more threads.
  • One of these known devices consists of a velvet cushion, which is attached outside the thread balloon area. After removing the required thread reserve, the operator holds the end with one hand and with the other hand guides the thread coming from the bobbin onto the pillow and presses it there. No curls form between the spool and the pillow if the thread runs tangentially away from the spool. The thread length obtained in this way is very modest and detaches from the pillow with the slightest pull.
  • Clamping devices are already known which hold the thread. However, these devices cannot satisfy either because the operator must first open the clamping device to insert the thread and therefore needs both hands for the process.
  • This device is completely unusable for fine yarns and in particular on specialist machines, since no free balloon formation and therefore no clean drainage of the yarn from the bobbin surface is possible. Furthermore, automatic start-up of the machine is not possible without additional thread guiding means which keep the yarn out of engagement with the bristle ring.
  • the object of the present invention is now to prevent the formation of curls or the detachment of turns from the bobbin surface when the winding process is interrupted at the winding point.
  • a further object of the invention is that both thread reserves of threads drawn off over the head and of threads drawn tangentially from rotating bobbins are possible.
  • Another object of the invention is to provide a device with which thread reserves can be built up without curling.
  • Another object of the invention is that the device keeps the thread free of curls even when work is interrupted.
  • Another advantage of the invention is that the movement of the eyelet and / or the spool can be carried out with little technical effort.
  • a thread reserve can easily be removed by hand even when the distance between the eyelet and the bobbin is reduced.
  • Another advantage of the invention is that the thread reserve can be released onto the thread with a low tensile force.
  • Another advantage of the invention is that the thread reserve can be used for threads drawn off overhead as well as for tangentially drawn threads.
  • the thread reserve can be formed on the bobbin tube itself.
  • the thread reserve can be formed on the spool pin.
  • Another advantage of the invention is that no elements that interfere with the handling of the machine have to be provided in the area of the thread path.
  • Another advantage of the invention is that the thread reserve can be released in several steps.
  • Another advantage of the invention is that both right- as well as left-wound or wound threads can be placed in reserve.
  • Another advantage of the invention is that if one of the threads breaks when the thread or threads are broken, they can also be placed in a reserve loop and therefore do not have to be reattached.
  • a coil 1 is placed on a mandrel, not visible in the figure, which engages in the sleeve 2 of the coil 1, and is held in this in a rotationally fixed manner (Fig.la.).
  • a large number of turns lie on the coil 1, but only three of them are shown individually with the reference symbols a, b, c. Together they form the thread 3.
  • a slotted disc 6 can also be provided (FIGS. 2a, 2b), or the extension 4 may have a gooseneck 7 (FIG. 3).
  • the coil sleeve 2 itself can be extended by a few centimeters (FIG. 4) and have an end piece 8 at the top similar to the end piece 6 in FIG. 2a.
  • a conical section 13 can be provided at the root of the extension 4 (Fig.la).
  • the surface of the extension 4 is preferably polished so that the thread 9 cannot be damaged when pulled off and slides with the least resistance.
  • the thread tension at the thread end 9 can drop at any time without a curl occurring in the reserve on the surface of the bobbin 1.
  • FIG. 5 shows a thread 13 drawn off tangentially from a bobbin 11.
  • Two turns d 'and e' are placed on an extension 14.
  • the thread loop B of the thread end 19 slides on the upper edge 2o, which leads to the turns a ', b', c '.
  • the tangential withdrawal of the thread 19 makes it unnecessary to attach an end piece to the extension 14.
  • the thread 25 forms a revolving balloon 29 when it is pulled off.
  • the thread consequently runs directly from the bobbin surface to the eyelet 24 without touching the edge 211 of the bobbin 23.
  • the eyelet 24 is attached to an arm 210 and can be pivoted with it from the working position into a rest position (dashed lines). In the rest position, the distance h o from the eyelet 24 to the coil 23 is reduced to a fraction of the original value.
  • the thread 25 then forms an angle ⁇ ⁇ 60 ° with the end face 213 of the bobbin and is deflected or braked by the upper edge of the bobbin 23.
  • the angle ⁇ of the thread 25 is preferably 45 ° ⁇ lo °.
  • the pivoting of the arm 210, or the displacement of the arbor 22 can be done mechanically or pneumatically.
  • the choice of drive system will depend on the type of drive already available on the machine.
  • the machine control for example after receiving a signal from the thread monitoring, causes the arm 210 to pivot and / or the winding mandrel 22 to be displaced, so that the distance between the eyelet 24 and the bobbin 23 increases reduced to the amount h 1 and the thread 25 thereby deflected at the edge 211 of the bobbin 23 and thus the friction at the edge 211 is increased.
  • the thread turns 212 lying above can no longer detach from the bobbin 23. The formation of curls both on the spool surface and in the rest of the thread path is thus excluded.
  • the speed at which the distance h o between the eyelet 24 and the bobbin 23 is reduced must be adapted to the respective thread take-off speed.
  • the length of the thread required for attachment in the event of thread breakage can be subtracted from the bobbin 23 by hand to overcome the friction and, for example, be pulled in again after the thread breaks.
