Definitions
- the invention relates to a method for winding a thread with a Thread reserve on a bobbin tube by means of a winding device Twisting machine or the like, in which at the beginning of the winding of one fixed guidance coming threads by means of a thread guide outside of actual winding zone of the bobbin tube is initially performed to an insufficient twisted piece of waste thread directly onto one end of the bobbin tube or if necessary, wind up a waste roll arranged next to the bobbin tube which then the thread by means of the thread guide in a next to the Winding zone lying area of the coil tube is passed to the side of the Winding zone a properly twisted piece of thread to form a Thread reserve on the bobbin tube, and finally the thread from the thread guide is released so that it by a traversing thread guide detected and can be wound up in the winding zone.
- the invention further relates to a winding device for winding a thread with a thread reserve on a bobbin tube, in particular for a twisting machine, with a coil frame which rotatably accommodates the coil sleeve, with a Bobbin drive roller, with a reciprocating parallel to this Traversing thread guide, which the thread coming from a central guide in the Area of a winding zone of the bobbin back and forth, and with one Thread guiding device for forming the thread reserve, which in the area of one End of the bobbin outside the winding zone around a parallel to the axis of rotation of the Spool drive roller extending axis is rotatable and two in their direction of rotation and has axially offset thread guide, the first thread guide further away from the take-up zone and the thread at the beginning of the Winding up to form a waste wrap directly on one End of the bobbin tube or possibly a waste roll arranged next to it leads and releases after partial rotation of the thread guide device about its axis, and wherein the second
- thread reserve When winding a thread on a bobbin tube is at the beginning of the winding process at one end of the bobbin tube to the side of the actual winding zone, in which later the thread is wound crosswise onto the bobbin tube, one so-called thread reserve formed.
- This thread reserve will later serve as the beginning a thread from one spool with the end of the thread to another spool connect before the one spool is completely unwound.
- the thread is still untwisted or insufficient rotated because it takes some time for the twisting spindles to reach their operating speed to have.
- the thread reserve must not have an untwisted or insufficiently twisted thread included, as otherwise a reduction in the quality of the product made from the thread entry.
- the thread guide consists of a rotatable, essentially frustoconical body. This is by means of a belt drive and one intermediate gear driven by the take-up roller, making it a very performs slow rotation.
- the frusto-conical body points at its from the Winding-up zone distal end extending approximately half the circumference, helical narrow groove in which the thread at the beginning of the Winding process is hooked. The thread runs from this narrow groove outermost coil end, where the waste winding is first wound up. During this happens, the truncated cone-shaped thread guide continues to turn after half a turn the thread jumps into a wider groove, which adjoins the narrow groove connects.
- the thread comes on a groove flank of the wider groove that is closer to the take-up zone, to the system, which means that it is now at a distance from Waste winding a thread reserve is wound on the bobbin tube.
- the groove flank of the wider groove runs helically. This has the consequence that too Start winding up the thread reserve of the thread at a greater distance from the actual winding zone is wound up and then as a result of Further rotation of the thread guiding device approaches the winding zone more and more.
- the mentioned groove flank is interrupted at one end. This has the consequence that after about a full revolution of the thread guide device, the thread no longer the groove flank is held and released by the thread guide.
- the Traversing thread guide catches the released thread and now begins with the crosswise winding of the thread in the area of the winding zone of the bobbin tube. After the winding process is finished, the thread must be between the thread reserve and the waste winding is cut and the latter are removed from the coil tube. The end of the thread coming from the thread reserve is now exposed and can move away from the Loosen the bobbin tube because the other windings of the thread reserve do not reach the end of the thread cover.
- the thread reserve is therefore not tied and can move on its own to solve. This is particularly disadvantageous if the thread produced, such as Tire cord has high strength. A loosened and dragged The thread reserve is used for transport, intermediate storage and further processing the coil is not portable.
- FR-A-2 370 409 discloses an apparatus for producing two thread reserves by means of an axially rotatable auxiliary thread guide, the winding on the outer End of the bobbin begins and ends adjacent to the winding zone of the thread.
- the thread reserves do not become clean side by side from the outside inwards placed, but in each case at the location of the outer thread reserve or at the location of the inner thread reserve coiled randomly and randomly. That from the Thread reserve coming thread end is not fixed and can therefore differ from the Loosen the coil sleeve.
- two long thread reserves are formed, which creates thread is wasted.
- the invention is therefore based on the object of a method and a Winding device for winding a thread with a thread reserve on a To show bobbin tube of the type mentioned, the winding of a perfectly tied thread reserve, which does not come loose on its own, in simple Enable way.
- the invention is therefore based on the idea that the method or the To design the device so that after the formation of the waste winding of the thread means the thread guide first in the vicinity of the winding zone of the bobbin tube brought. During the winding of the thread reserve, the thread is then used the thread guide gradually from the take-up zone to the bobbin end moved there. As a result, the thread windings of the thread reserve over the Waste winding coming and running in the vicinity of the winding zone wound. If later this thread piece between thread reserve and waste winding is severed, its end is by the turns wound over it Thread reserve tied in such a way that it does not come loose on its own. Since the thread during formation of the thread reserve towards the end of the bobbin, he lies down, if it is released by the thread guide after completion of the thread reserve is crossing over the thread reserve, whereby an additional securing of the same is achieved.
