When making band 54 contact with band 44, band 44,54 bending.Now, as it has been described above, Due to between driving pulley 41 and the driven pulley 42 of 44 part central part with 54 active Between belt wheel 51 with driven pulley 52, the central part of part contacts, and therefore band 44 is at driving pulley 41 And the part between driven pulley 42 bends equably, band 54 is at driving pulley 51 and driven pulley 52 Between part bend equably.

Further, in this embodiment, by movable belt unit 32 as described above along with band 44,54 The direction of the phase of outer peripheral face partial orthogonality opposite one another is moved, and makes band 54 contact, therefore with band 44 The contact pressure on the width of band 44,54 can be made uniform.

In belt type false twister 24, if by making movable belt unit 32 leave fixing band unit 31 Make band 54 leave the repiece with carrying out under the state of 44 to yarn-finished portion 12, then as Fig. 4 (a), B, as shown in (), yarns Y is by, between band 44 and band 54, becoming being positioned at of yarns Y adjacent By contacting with the outer edge of end face disk 45 with the part in downstream with the part between 54 with 44 State.Making motor 46,55 drive in this condition makes band 44,54 walk, and then makes movable Tape cell 32 is near fixing band unit 31, by so making band 54 contact with band 44.Then, as figure As shown in 3 (a), (b), yarns Y carried 44 and band 54 clip, carry 44 in this condition, 54 walkings.Thus, yarns Y is being twisted with the fingers with stopping with the rhombus part intersected with 54 i.e. cross point C with 44 Part between yarn guide 22 is paid sth. made by twisting.Further, yarns Y is at cross point C and secondary yarn feeding roller Part between 25 is untwisted.Now, due to the downstream that is positioned at adjacent cross point C of yarns Y Part contacts with the outer edge of end face disk 45, and therefore yarns Y is between cross point C and end face disk 45 Part untwisting be suppressed, untwisting starting point is fixed on end face disk 45.

Wherein, if the untwisting starting point of yarns Y is positioned at cross point C, due to the yarn being untwisted , there is yarns Y and produce the worry of burr in line Y and band 44,54 friction.Further, now yarns Y Untwisting starting point be located the upstream part in yarn road of cross point C, the yarns Y being untwisted with Length with 44,54 frictions is the longest, and yarns Y the most easily produces burr.As above-mentioned in this embodiment The untwisting of yarns Y part between cross point C and end face disk 45 like that is suppressed, yarns Y Untwisting starting point is fixed on end face disk 45.Therefore, compared with the situation not having end face disk 45, yarn The untwisting starting point of line Y is displaced to the downstream in yarn road.Thereby, it is possible to make the untwisting of yarns Y start Point is positioned at the downstream leaning on yarn road than cross point C.Thereby, it is possible to the yarns Y that suppression has been untwisted is produced Setation stings.

Wherein, in order to make as described above band 44 between driving pulley 41 and driven pulley 42 uniformly Ground bends, makes band 54 bend equably between driving pulley 51 and driven pulley 52, preferably as upper State and make the central part of part between the driving pulley 41 of band 44 and driven pulley 42 like that and with 54 Between driving pulley 41 with driven pulley 52, the central part of part contacts.On the other hand, in order to hand over Fully suppress the untwisting of yarns Y between crunode C and end face disk 45, untwisting starting point is fixed on end On face 45, cross point C is preferably made to be positioned as close to end face disk 45.Further, this enforcement shape By being positioned as close to configuration driving pulley 41 and driven pulley 42 and driving pulley respectively in state 51 and driven pulley 52 meet these conditions.

Now, if different from the present invention, fixing band unit 31 not band extends with belt wheel 43, band 44 are only wound around on 2 belt wheels 41,42, if then near configuration driving pulley 41 and driven pulley If 42, the length with 44 just shortens.Equally, use if movable belt unit 32 not band extends Belt wheel 53, band 54 is only wound around on 2 belt wheels 51,52, if then near configuration driving pulley 51 If driven pulley 52, the length with 54 just shortens.

Wherein, if the length with 44 is short, then, after certain part with 44 contacts with band 54, arrive The time that this part with 44 contacts with 54 next time shortens.Therefore, each several part with 44 arrives After cross point C and yarns Y frictional heating, before sufficiently cooled, arrive again at cross point C, With yarns Y frictional heating.As a result, the temperature with 44 entirety uprises (such as more than 100 DEG C), resistance to Property have dropped for a long time.

Equally, if the length with 54 is short, then, after certain part with 54 contacts with band 44, arrive This part with 54 shortens with 44 times contacted next time.Therefore, each several part with 54 arrives After reaching cross point C and yarns Y frictional heating, before sufficiently cooled, arrive again at cross point C, With yarns Y frictional heating.As a result, the temperature with 54 entirety uprises (such as more than 100 DEG C), resistance to Property declines for a long time.

Further, owing to the thickness of now yarns Y is the thickest, the frictional heat of yarns Y and band 44,54 is got over Greatly, the probability therefore producing the problems referred to above uprises.

Further, with 44 hang up on belt wheel 41～43 part bending, if but with 44 length Short, then, when carrying 44 walking, each several part with 44 arrives the number of times of belt wheel 41～43 bending to be increased. As a result, easily producing the core with 44 and rupture, peel off, the durability with 44 declines.Equally, band 54 in the part bending hanged up on belt wheel 51～53, if but length with 54 is short, then carry 54 During walking, each several part with 54 arrives the number of times increase that belt wheel 51～53 bends.As a result, easily produce Core with 54 ruptures, peels off, and the durability with 54 declines.

In contrast, fixing band unit 31 is except driving pulley 41 and driven pulley in this embodiment Outside 42, also have and that be arranged in driven pulley 42 carry with driving pulley 41 opposite side band prolongation Wheel 43, band 44 is wound around on belt wheel 41～43.Thus, with band 44 be only wound around 2 belt wheels 41, Situation on 42 is compared, by increasing capacitance it is possible to increase with the length of 44.Equally, movable belt unit in this embodiment 32 in addition to driving pulley 51 and driven pulley 52, also have be arranged in driven pulley 52 with actively The band of belt wheel 51 opposite side extends with belt wheel 53, carries 54 to be wound around on belt wheel 51～53.Thus, Compared with the situation being only wound around 2 belt wheels 51,52 with 54, by increasing capacitance it is possible to increase with the length of 54.And And, if the length with 44,54 is long, then each several part with 44,54 arrives cross point C and yarn After line Y frictional heating, sufficiently cooled after arrive again at cross point C, with yarns Y frictional heating. Therefore, no matter yarns Y thickness how, and rising with 44,54 bulk temperatures is suppressed, it is possible to prevent Durability with 44,54 declines.

Further, if with the length of 44, then when walking with 44, each several part with 44 arrives belt wheel 41～43 and the number of times that bends tail off.Therefore, it is possible to suppress the core fracture with 44, stripping to cause The durability of band declines.Equally, if with the length of 54, then with during 54 walking with 54 each Part arrives the number of times of belt wheel 51～53 bending and tails off.Therefore, it is possible to suppression band 54 core fracture, The durability peeling off the band caused declines.

Further, in this embodiment, in belt type false twister 24, if paying sth. made by twisting to yarns Y Time mobile shaft 73 (band prolongation belt wheel 53) make the tension variation of band 54, then band 44 and band 54 Contact pressure change.Thereby, it is possible to control by band 44,54 conveying yarn according to the tension force etc. of yarns Y The power of line Y and pay the power of sth. made by twisting to yarns Y.Now, the tension force with 54 is the biggest, band 44 and band The contact pressure of 54 is the biggest, pays the power change of sth. made by twisting greatly by the power with 44,54 delivered yarn and to yarn.

Wherein, it is also possible to consider different from the present invention, (band extends with belt wheel 53 to replace mobile shaft 73 Central shaft 53a) and by mobile shaft 71 (the central shaft 51a of driving pulley 51) or rotating shaft 72 (the central shaft 52a of driven pulley 52) makes the tension variation of band 54.But, in this case, When mobile shaft 71 or 72, exist with 54 with 44 contact portion produce tilt, carry 44 The worry declined with the close property with 54.

Be described in more detail for, in belt type false twister 24, by 54 clipping yarn with band 44 and band Make band 44,54 walk under the state of Y, apply power to yarns Y, yarns Y is transported to yarn road Downstream, and pay sth. made by twisting to yarns Y.Now, in order to make the power paying yarns Y stable, there is band 44, necessity that 54 parts contacted with each other the most fully are close to.But, if different from the present invention, If making rotating shaft 71 or 72 move, then there is the axle moved and tilt, with 54 with 44 connect Contact portion divides the worry producing inclination.Further, if producing such inclination on band 54, then there is band 44 The worry declined with the close property with 54.

In contrast, owing to being adjusted by mobile shaft 73 (band extends with belt wheel 53) in this embodiment Therefore the tension force of whole band 54, even if adjusting the tension force with 54 also can maintain rotating shaft 71 (driving pulley 51) Position relationship with rotating shaft 72 (driven pulley 52).Therefore, when have adjusted the tension force with 54, band 54 will not tilt with the contact portion with 44.

Further, this embodiment does not produce inclination in order to make band 54 with the contact portion with 44, Precision is had to maintain necessity of state the most parallel to each other well for rotating shaft 71,72.In contrast, Even if rotating shaft 73 is slightly tilted relative to rotating shaft 71,72, with 54 with 44 contact portion Also will not tilt.Therefore, be used for support rotating shaft 73 structure, for mobile shaft 73 structure also Less require high precision, it is possible to use simple structure.

Then illustrate this embodiment is applied with the variation of all changes.

In above-mentioned embodiment, driving pulley 41 and driven pulley 42 are the portion with same diameter D1 Part, driving pulley 51 and driven pulley 52 are the parts with same diameter D1, but are not limited to This.
