Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention provides a method for winding a cross-wound thread body. Regarding T'. In more detail 1 = <, the present invention comprises: a winding roller that rotates a yarn winding bobbin; a clay 8tor that rotatably supports the yarn winding bobbin and presses against the winding roller; 7. Regarding a method of winding a crosswind winding body using a traverse guide that traverses in the axial direction of a yarn winding bobbin, in particular, winding a crosswind winding body at a relatively low speed using a twisting machine, a covering machine, etc. This invention relates to a method for winding a cross-noin thread body that can be adapted to equipment.

[Conventional technology]

When winding up the crosswind winding body (step 7), press the yarn winding bobbin against the winding roller, and traverse the yarn from side to side with the screwdriver guide. Wind up the yarn and make 2.

1 = The thread is traversed on the rubber guide, drawing an isosceles pentagon from one traversing point, and moving it to the bobbin J.

(see Figure 2), the winding tension increases as the traverse guide moves from the center to the traverse end. That is, with respect to the distance L between the traverse point and the guide at the center of the traverse, the tension is high because the distance between the traverse point J and the traverse guy F towards the end of the traverse is [1, 1 or an increasing sign]. This is because that.

In this way, if there is a large tension difference between the center of the traverse and the ends of the traverse, the quality of the yarn changes, especially at the ends of the traverse.
When weaving or knitting using yarn, there is a problem in that so-called sink marks, clusters, etc. occur in the product.

The above-mentioned problems such as whiskers and clusters are particularly likely to occur when the winding yarn does not have elasticity.

As one of the countermeasures for such problems, conventionally, L, /S between the traverse length 11 between the traverse point and the traverse guide and the movement MS of the traverse guide is increased, and the relative proportion of tension fluctuation is reduced. Measures are being taken to reduce this.

In addition, in another method, the bar guide provided between the traverse fulcrum guide and the traverse guide ♂ has an arcuate shape 2 that bulges in the opposite direction to the traverse guide (the traverse length L at the center of the traverse is It is known that the traversing length of the end of the heel is approximately equal to I, 1.

[I-J style of invention]

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide a winding method in which fluctuations in winding tension are extremely small even if the distance between the traverse guide and the traverse guide is relatively short. do.

[Means for Solving the Problems] The present invention has the above-mentioned object by providing a winding roller for rotating the yarn winding bobbin, which supports the yarn winding bobbin in a rotatable manner. In a method for winding a cross-winding yarn body using a cradle that is in pressure contact with the winding roller and a rubber guide that traverses in the axial direction of the yarn winding bobbin, the traverse guide is a rubber guide. The speed of the take-up roller is reduced while the traverse guide moves from the center point of the rubber toward the traverse end, and the speed of the take-up roller is reduced while the traverse guide moves from the end of the rubber to the center point of the traverse. This is achieved by a crosswind winding method characterized by increasing the speed.

[For production]

In the present invention, C reduces the speed of the take-up roller by -1 while moving from the traverse guide or the center point of the traverse toward the traverse end, while moving from the traverse guide or the traverse end to the center point of the traverse. During the interval, the speed of the winding roller is increased, so when the winding tension increases due to an increase in the winding length, the speed of the winding roller is reduced [2 to absorb the increase in winding tension, and , [
・If the winding tension during the movement of the traverse from the end of the traverse to the center is low, increase the speed of the winding roller to increase the winding tension by 4. It can be used as winding tension.

As a result, the winding tension acting on the yarn in the crosswine F winding body during winding is approximately constant, so that a yarn with uniform yarn quality can be obtained.

[Examples] A detailed description of the present invention will now be given with reference to the accompanying drawings.

As shown in FIG. 1 and FIG. 2, the yarn F whose direction has been changed from the traversing fulcrum guide 1 by the hull guide 2 is traversed to the right by the traverse guide 3a of the rubber device 3. A bobbin 5 frictionally driven by a winding roller 4

In the present invention, the crosswind winding body is wound using a device similar to the one shown in FIGS. 1 and 2 mentioned above. 1, the traverse guide 3a is at the end of the traverse L:! Central part 1, ゛Time to move: tF (F<mark A) IX: is,
