The delivery roller 6, the fluff suppressing device 1, the slack tube 7, the yarn clearer 8 for detecting a yarn defect, and the winding device 9, which are in pressure contact with each other, are sequentially arranged from the upstream side to the downstream side. The sliver S supplied from No. 3 is drafted by the drafting device 4, then false twisted by the air spinning device 5, sent out from the delivery roller 9, and passed through the fluff suppressing device 1, so that the fluff is suppressed. In the winding device 9, while traversing the traverse guide 9a, the positively rotating winding drum 9b is pressed into contact with the winding drum 9b. And wound up as over-di-P.

The fluff suppressing device 1 is fixed to the tip of a frame 10 supporting a drive shaft 6b of the delivery roller 6 on the downstream side of the delivery roller 6 of the spinning machine 2 via a bracket 11, The fluff suppressing device 1 will be described below with reference to the drawings.

A fluff suppressing device 1 according to a first embodiment of the present invention shown in FIG. 2 includes a touch roller 12 that is driven to rotate, and a touch roller 12 that is obliquely contacted with the touch roller 12 and is between a drive pulley 13 and a driven pulley 14. It is mainly composed of the endless belt 15 mounted on the above, and is provided with a mechanism for feeding the spun yarn Y while nipping it with the endless belt 15 and the touch roller 12 and giving a false twisting and rubbing action to the spun yarn Y. .

The touch roller 12 is made of metal, and lateral lines are formed on the surface of the touch roller 12 by providing concave grooves parallel to the axial direction at a constant pitch.

The drive pulley 13 is a pulley with a collar formed with collars 13 a and 13 b on the outer peripheral edges thereof respectively to prevent the endless belt 15 from departing, and the collar 13 a on the yarn sending side of the endless belt 15 is a yarn introducing side. It has a larger diameter than the brim 13b. This is because the endless belt 15 is likely to come off to the yarn delivery side due to contact with the drivingly rotating touch roller 12. Further, the collar 13b on the yarn introducing side is held to the thickness of the endless belt 15 in order to avoid contact with the touch roller 12. The drive pulley 13 is fixed to one end of a rotary shaft 27 rotatably supported by a supporting member 18 with a screw 19, and the supporting member 18 is bolted to a bracket 11 fixed to a frame 10 with a bolt 16. It is fixed at 17.

At this time, the relative positional relationship between the drive pulley 13 and the touch roller 12 is as follows. That is, the rotation center line 13c of the drive pulley 13 is located outside the one end surface 12a of the touch roller 12, and the endless belt 15 is connected to the belt 15 and the touch roller 12 on the nip side (tension side) of the drive pulley 13. It is supported on the lower surface than the contact surface.

As a result, the endless belt 15 mounted between the drive pulley 13 and the driven pulley 14 is pressed against the touch roller 12 at the contact surface by appropriate contact pressure, and at the nip side of the drive pulley 13. It is possible to dispose the drive pulley 13 close to the touch roller 12 and obliquely while avoiding the contact of the collar 13b with the outer peripheral surface of the touch roller 12.

A bevel gear 26 is formed on the other end of the rotating shaft 27, and the bevel gear 26 is formed on the rotating shaft 24 of the friction roller 23 rotatably supported by the supporting member 18. Further, the friction roller 23 is in pressure contact with the roller 22 provided on the drive shaft 21 of the touch roller 12, whereby the rotation of the drive shaft 21 can be prevented by rotating the roller 22, the friction roller 23, the rotary shaft 24, It is transmitted to the drive pulley 13 via the pair of bevel gears 25, 26 and the rotary shaft 27, and the endless belt 15 is driven by the drive pulley 13 at a constant speed ratio with the touch roller 12.

The driven pulley 14 is rotatably supported by a support shaft 28 provided on the support member 20, and the support member 20 is fixed to the support member 18 by a bolt (not shown). Then, a thread guide piece 29 is provided so as to hang down on the lower surface of the support member 20.

In addition, in the fluff suppressing device 1'of the second embodiment of the present invention shown in FIG. 3, twill lines are formed by providing concave grooves on the surface of the touch roller 12 'in two oblique directions at a constant pitch. Has been done.

In addition, it is also possible to increase the friction coefficient of the roller surface by forming concave grooves on the surface of the touch roller at a constant pitch in one oblique direction to form slopes or by coating. is there.

Next, the operation will be described based on examples.

In the spinning machine 2 shown in FIG. 1, the sliver S supplied from the can 3 is drafted by the drafting device 4, then false twisted by the air spinning device 5, and sent out by the delivery roller 6 as spun yarn Yo. Many fluffs are formed on the surface of the spun yarn Yo in this state by the air action during spinning. Then, the spun yarn Yo sent out from the delivery roller 6 is guided by the yarn guide piece 29 in the fluff suppressing device 1 to come into contact with the touch roller 12 and the touch roller 12, and at the contact surface. The spun yarn Yo is fed while being nipped by the endless belt 15 which is driven in the direction of the middle arrow 30. At this time, the spun yarn Yo is given a false twisting and rubbing action, whereby the fluff on the surface of the spun yarn Yo The spun yarn Y is wound around itself and is delivered to the downstream side as a spun yarn Y having substantially no fluff, and is wound as a package P in a winding device 9 through a yarn clearer 8.

As shown in FIGS. 2 and 3, since the touch rollers 12 and 12 ′ are made of metal, they have excellent wear resistance, can be directly fixed to the drive shaft 21 and can be used permanently, and On the other hand, since the roller surface is subjected to a friction coefficient increasing process such as a horizontal line and a twill line, when the spun yarn Y is nipped and fed by the rollers 12 and 12 'and the endless belt 15, the endless belt 15 The slip of the spun yarn Y in the driving direction of the spun yarn is prevented, false twisting is possible, and the quality of the spun yarn Y is kept constant.
