Take-up winder

Abstract

An object of the present invention is to set a bend angle ¸ equal to or smaller than a management upper-limit bend angle ¸k and to reduce the need to install a second godet roller at a higher position without the need to increase the number of guides. A take-up winder 1 includes a spinning section 2, a first godet roller 3 and a second godet roller 4 arranged in order along yarn paths of yarns Y spun by the spinning section 2, a bobbin holder 5 supporting a plurality of take-up bobbins 7 around which the respective yarns Y fed from the second godet droller 4 are wound, and a plurality of traverse support point guides 6 each configured to set a traverse support point for traversing of the corresponding one of the yarns Y fed from the second godet roller 4. The plurality of winding bobbins 7 are coaxially supported by the bobbin holder 5. The axial direction 4j of the second godet roller 4 is set to be orthogonal to the axial direction 7j of the take-up bobbins 7. Each of the yarns Y bent at the respective traverse support point guides 6 by more than the management upper-limit bend angle ¸k is bent by a close guide 9 provided upstream of and close to the corresponding traverse support point guide 6.

Description

technical field [0001] This invention relates to spin winders. Background technique [0002] As such a technique, a conventional spinning winder is mentioned in Patent Document 1 (Japanese Patent Application Publication No. 2-41490). as in this application figure 1 As shown, this spinning winder adopts the method of wrapping the melt-spun synthetic fiber strands from the spinning unit (hereinafter referred to as "filaments") in turn on the first godet roll and the second On the godet roll, use the traversing fulcrum guide and the reciprocating traversing guider to wind the yarn conveyed from the second godet roll onto the winding bobbin while traversing it, thereby simultaneously Form a structure of multiple packages. [0003] Specifically, the above-mentioned winding bobbins are supported by bobbin holders, and a plurality of winding bobbins are arranged side by side along the axial direction of each winding bobbin, and the direction in which these winding bobbins are ar...

Problems solved by technology

However, in this case, because of the addition of a guide, there is a possibility that the resistance to the progress of the yarn will increase, and the quality of the yarn will be deteriorated.

[0008] On the other hand, in the above-mentioned patent document 1, there is no mention at all of the bending angle of the thread at the traversing fulcrum guide.

[0009] Therefore, as described above, the above-mentioned bending angle θ is kept below the management upper limit bending angle θk, and the number of guides is not greater than figure 1 In the example of the prior art shown, under such preconditions, to increase the length of the bobbin support, there is no other means except to further increase the setting position of the second godet roller, and some kind of technical breakthrough is required
