Here, conveying is closelyed follow the axis horizontal that preceding yarn feeding roller 121 is configured to roller with yarn feeding roller 10 and first.On the other hand, second is configured to tip side a little up the tilt posture in several years with the axis of this roller 122 with respect to horizontal line immediately following preceding yarn feeding roller 122.Make as mentioned above first immediately following preceding yarn feeding roller 121 with respect to second immediately following preceding yarn feeding roller 122 tilt be for: with yarn 101 around to these rollers 121,122 time, yarn 101 can not center on the same position on the roller 121,122, and makes yarn 101 axially moving successively naturally along roller 121,122.Therefore, when the base end part that makes yarn 101 from roller 121,122 (left frame 71 1 sides) centers on, Yi Bian yarn 101 is hung yarn to the tip side (correct frame 72 1 sides) of roller 121,122 to roller 121,122 on one side change centers on the position successively.

From carrying 101 groups on the yarn sent with yarn feeding roller 10, be suspended to a pair of closelying follow on the preceding yarn feeding roller 121,122 with around a pair of mode immediately following preceding yarn feeding roller 121,122.These closely follow the heater that preceding yarn feeding roller 121,122 possesses stretching usefulness, give around a pair of yarn immediately following preceding yarn feeding roller 121,122 and apply suitable heat for 101 groups.

And,, provide the threads 101 that comes before arriving up-coiler 30, to be stretched fully from spinneret 90 carrying with yarn feeding roller 10 and closelying follow between the preceding yarn feeding roller 121,122 and give speed discrepancy.

Provide the above-mentioned threads 101 that comes temporarily all to offer first from a spinneret 90 immediately following preceding yarn feeding roller 121.Threads 101 is being closelyed follow preceding yarn feeding roller 121 around a pair of immediately following getting back to first after the preceding yarn feeding roller 121,122 then, and the yarn 101 of half is assigned to first immediately following preceding yarn feeding roller 121.And remaining half yarn 101 is sent to second immediately following preceding yarn feeding roller 122, is assigned to second immediately following preceding yarn feeding roller 122.

That is, the half yarn 101 from the above-mentioned threads 101 that spinneret 90 provides distributes to first immediately following preceding yarn feeding roller 121, and remaining half yarn 101 is assigned to second immediately following preceding yarn feeding roller 122.

Here, above-mentioned second is the inclined degrees that total extension yarn girth do not exerted an influence immediately following the angle of inclination of preceding yarn feeding roller 122, i.e. the inclined degree that physical property of yarn 101 is not exerted an influence.Therefore, not can because of second immediately following the inclination of preceding yarn feeding roller 122 make distribute to first immediately following 101 groups on the yarn of preceding yarn feeding roller 121 to closely follow the physical property of 101 groups on yarn of preceding yarn feeding roller 122 different with distributing to second.

Two immediately following preceding yarn feeding roller 121,122 below, dispose up-coiler 30.Immediately following the direction that is set up in parallel of preceding yarn feeding roller 121,122 is fore-and-aft direction, along the bobbin holder axle 31 of up-coiler 30 axially.

A plurality of bobbins 2 are installed on bobbin holder axle 31.Here, the quantity of the bobbin of installing on 1 bobbin holder axle 31 2 is identical with the radical (radical of 1 spindle) of the yarn 101 that provides from spinneret 90.

In the present embodiment, 10 one threads 101 that provide from spinneret 90 are reeled in each of 10 bobbins 2 by traversing gear group 32 back of traversing 1 up-coiler 30.

Provide the threads 101 that comes as mentioned above from spinneret 90, at first be assigned to a pair of each immediately following preceding yarn feeding roller 121,122.In the present embodiment, 5 velamens of the half in 10 are distributed to each immediately following preceding yarn feeding roller 121,122.Immediately following in each of preceding yarn feeding roller 121,122, the yarn 101 that is distributed (5 one thread 101) group is spread one by one, through with the thread guide eyelet of each bobbin 2 corresponding fulcrum thread-carrier 32a that traverse, offer each bobbin 2.

And threads 101 is being carried with yarn feeding roller 10 and is being closelyed follow between the preceding yarn feeding roller 121,122 and carried up and down, but as a whole, carries toward the up-coiler 30 of lower positions from the spinneret 90 of top position.

The meaning immediately following " immediately following preceding " in the preceding yarn feeding roller 121,122 is meant, these yarn feeding rollers are positioned at closelying follow of relative each bobbin 2 (up-coiler 30) on throughput direction before.The part of above-mentioned threads 101 offers second immediately following preceding yarn feeding roller 122 through first immediately following preceding yarn feeding roller 121, but first self also is the yarn feeding roller of " immediately following preceding " with respect to bobbin 2 (up-coiler 30) immediately following preceding yarn feeding roller 121.

Distribute to immediately following 101 groups on the yarn of preceding yarn feeding roller 121 (or 122) along fore-and-aft direction (with direction) diffusion, similarly led respectively along a plurality of bobbins 2 of fore-and-aft direction configuration immediately following the axial quadrature of preceding yarn feeding roller 121,122.

Distribute to immediately following the diffusion of 101 groups on the yarn of preceding yarn feeding roller 121 (or 122) and also the outer peripheral face immediately following preceding yarn feeding roller 121 (or 122) can be carried out as starting point, but be that starting point is carried out to be configured in thread-carrier 60 in the present embodiment, immediately following the shredding under the top ends of preceding yarn feeding roller 121 (or 122).

This shredding is used as the guide portion of yarn 101 with having formed quantity and quantity (in the present embodiment being 5) inserting hole or the groove that equate, yarn 101 of distributing to 101 groups on pairing yarn immediately following preceding yarn feeding roller 121 (or 122) on the thread-carrier 60.The fulcrum that a plurality of yarns 101 that distributed spread as yarn with thread-carrier 60 with this shredding respectively along the fore-and-aft direction diffusion, and offers up-coiler 30 1 sides.

So, distribute to 101 groups of fulcrums that spread as yarn with thread-carrier 60 with shredding of each yarn immediately following preceding yarn feeding roller 121 (or 122), spread along fore-and-aft direction, and offer up-coiler 30, thus, make threads 101 on fore-and-aft direction, separate certain interval to the in-position of traversing gear group 32.Therefore, can make each yarn 101 of separating certain intervals on the fore-and-aft direction through each traversing gear that formation traversing gear groups 32 be wound up into independently be installed in series on the bobbin holder axle 31 of fore-and-aft direction, be positioned at each traversing gear under each bobbin 2 on.

Above-mentioned shredding is the parts immediately following the fulcrum that the yarn diffusion is provided on the position of preceding yarn feeding roller 121 (or 122) that are driven in rotation leaving with thread-carrier 60, make to drive to be difficult to influence each yarn 101, thereby prevent the yarn swing immediately following the caused vibration of preceding yarn feeding roller 121 (or 122).

And, by shredding with thread-carrier 60 on rather than immediately following the fulcrum that the yarn diffusion is set on the outer peripheral face of preceding yarn feeding roller 121 (or 122), thereby on throughput direction, be assigned to same each yarn 101 and leaving immediately following the urgent front yarn feeding of same position roller 121 (or 122) on the outer peripheral face of preceding yarn feeding roller 121 (or 122) immediately following preceding yarn feeding roller 121 (or 122).That is, at yarn 101 each other, do not create a difference with the distance that contacts of the outer peripheral face of closelying follow preceding yarn feeding roller 121 (or 122).

101 groups on the yarn that is distributed through shredding with thread-carrier 60 forwards, backwards direction spread one by one, but for quality of yarn is kept certain, the angle (yarn angle of inclination A) of this yarn diffusion relatively the vertical line maximum 20 spend below.

In the present embodiment, owing to adopt 5 one threads 101 are distributed to the structure of closelying follow preceding yarn feeding roller 121 (or 122), therefore 1 velamen is sent to shredding with under the thread-

carrier

60,2 velamens are sent to the front side of shredding with thread-

carrier

60,2 velamens are sent to the rear side of shredding with thread-carrier 60, as the center, remaining 4 one threads 101 are carried with the front and back symmetrical manner with the yarn under above-mentioned being sent to 101.When distributing to radical immediately following 101 groups on the yarn of preceding yarn feeding roller 121 (or 122) and be even number, be not sent to shredding with the yarn under the thread-carrier 60, but 101 groups on yarn spreads with the front and back symmetrical manner.And structure is, at the transport path of the yarn 1 of the fulcrum thread-carrier 32a that traverses that is sent to front side and be sent on the bisecting line between the transport path of yarn 1 of the fulcrum thread-carrier 32a that traverses of rear side, the configuration shredding is with thread-carrier 60.

In the present embodiment, the yarn 101 and the angle between the vertical line that are sent to the yarn 101 and the angle between the vertical line of front side and are sent to rear side all are about 17 degree, below 20 degree.Other 3 lines and the angle between the vertical line are less than the yarn 101 that is sent to front side and rear side, certainly also below 20 degree.

Be provided with immediately following the layout between preceding yarn feeding roller 121 (or 122) and the up-coiler 30, so that carry out this yarn diffusion.In more detail, in up-coiler 30, the yarn introduction part (fulcrum thread-carrier 32a traverses) that imports to each traversing gear that constitutes traversing gear group 32 is positioned at the in-position that each yarn 101 enters up-coiler 30, is set in below above-mentioned 20 degree with direction and angle vertical (yarn angle of inclination A) of thread-carrier 60 to this in-position from shredding.

Be transported to shredding and compare with the yarn under the thread-carrier 60 101 (yarn of on vertical line, carrying), the yarn 101 that is transported to vertical line front side or rear side buckles with thread-carrier 60 or the yarn introduction part (fulcrum thread-carrier 32a traverses) that imports each traversing gear in shredding, has been applied in unnecessary tension force.For the harmful effect that applies this tension force is minimized, make yarn diffusion with respect to the maximum angle of vertical line below above-mentioned 20 degree.

In addition, certainly, be installed in each bobbin 2 on the bobbin holder axle 31 and be configured under yarn introduction part (fulcrum thread-carrier 32a traverses) that each traversing gear imports.
