Abstract
In a process for air texturing yarns (1, 2, 3) made from glass fibres, the glass fibres are fed separately to a first delivery device (4) and then pass through a texturing nozzle (6) where a false twist is imparted to them, at least in the region between the inlet and outlet of the texturing nozzle. A device for implementing the process has a false-twisting device (9) between the first delivery device (4) and the second delivery device (10). The deflecting body of the false-twisting device (9) is a twisting pin (13) rotatably mounted about its own axis, which may be inclined to the direction of transport of the yarns (1, 2, 3).

PROCESS AND ~EVICE FOR AIR TEXTURING
Specification -The invention relates to a ~rocess for air texturing yarns made frorn glass fibres in which the fibres are fed tc~ a first deliverv device and then ~ass through a t.e~turi1lg nc~zzle a11d finallv to a secc)nd delivery device. The invention furtll~r relates tC~ a device tc~
carry C)llt t]liS proc:ess l~ith a first and seco1ld deliverv device an-1 a te~t~lring nozzle arranged bet-~een them.
prC)C'eSS i9 ~nc)wn wllereb~ fibres e.g. ~lass fibres toc~ are fed Wit]lC)l1t beiny t:wisted intc) a texturiny noæzle from a first delivery device and fron1 there into a second delivery device. I~ith this process there is a dan~er that individua]. filaments of the fibres fed intc, the device s~ill break at the inlet to the text1lring nozzle which can result in hold-t1ps and finally breakin~ of the yarn. Single untwisted yarn~ of this type tend to swe~ p in the teYturing nozzle in an uncc~ntrolled, uneven manner. The te~turecl yarn thus obtained i~ unsatisfactorv for many applications.
A further process ls know1l in which fihres coming frorn spinning bobbins are brought together and twisted. The material thus obtained can be fed into a texturing nozzle. As a result of the twisting any broken filaments which mav have protruded are bound into the material again. This binding prevents broken filaments from catching at the inlet to the texturing nozzle. In addition this ~aterial produces a regularly fluffed up textured yarn. However the disadvantage of this process is that the twisting of the yarns is a separate ~ .
~55393 process carried out before the material is introduced intc) the ~e~turing nozzle and involving considera~le cost outl~v. ~ further disadvantage is that in the case of more bri~tle m~terial additic)llal agents are required to aid twistillg. For instance it is usual to applv so-called textile finishillg to glass fibre material in order to make twisting possible at all. This prc)cess not only involves additional costs but a further disadvantagt? is th.l~ the te,Ytile finishill~1 usecl causes problems during ~ubsequellt use of the yarn e.~. by rnaking embec~ding iSl a matrix mc)re difficult.
The taYk of the present invention is to pr-esent a process of the tvpe described at the begill]ling in wllicl the fibres to he textllred can be reliabl~ fec3 into the te~turing ll02zle and te~:tured there in an even manller at considerablv reduced ou-tlay and wc)rkload. The fibres 3hou].cl ollly be under sligllt: strain so that even in the case of critical yrirnary materials additio}lal au~iliarv agents can largely he dispensed l~ith. Another tas~ of the present invention is to desiyn a device to carrv out this process.
This task is sc~lved in acicc)rdance with the inventic)n by a proce~s of the kin~l described at the beginning in that the fibres are fed into the first delivery device either separately ~r plied and that the fibresi are given a ~
false twist. joining them together to forM a single unit ~-at least for the area between the inlet and the outlet ~ ;
of the texturing nozzle.
Thus no preparatory processing e.g. twistin~ is necessary before the material passes into the first delivery device. The false twist gathers the fibres ~ - .

' '; ,'':
~- , - :' 2~:!5~i393 ~7 into one unit and binds anv broken fibres into the l~hole so tllat hold-ups and obstructions at the nozzle inlet are avoided. The resulting bundled fibres enterillg the texturing nozzle ensure uniforrn swelling of the yarn.
The prc)cess in ~ccordance with the invelltion can be further developed so that the threads pass over a false-twisting device between the texturing nozzle and tlle secc)nd delivery device which applies a twist to the fibres i]l the area hetw~el7 tlle first delivery device anci the false-twi~ting device.
After leaving tlle textllring nc)zzle the fibres pass over a false-twisting device wllicll gives theln a t.wist ill the area J~etween the first de]iverv devlce and the. fal~e-ts~isting device. A3 a result of this the threads are bouJld together tc~ form a wllole at the same ti~ne binding any brokerl filaments wllich mav be rJresent. This ensures that the varn twisted in this wav enters the nc)zzle in the desired manner. The single yarn thus formed is also subjected as a whole to the air blast in the texturing nozzle. As a result the entire unit is affected rather than individual fibres sc) that the yarn swells evenly.
Thi~ ~dvantage is a~hieved without any additianal twisti~lg or rewinding procedures instead simply bv in erting any known type of false~twlsting device into the yarn flow.
The process in accordance with the invention can also be carried out in snch a way that a twist is applied to the yarn in the area of the texturing nozzle of up to 150 T/m. In many cases it is expedient to apply twi~ting of less than 100 Tim to the yarn in the area of the texturing nozzle. This twisting ensures that the desired advantages are achieved with respect to the ~ ~ ;

blastil~s procedure itself is favourablv affected within the nozzle. .~t the sarne time, however, fewer turns in th~ v3rn ~?rodl3ce less strain oll the individual filatoellts and, thus, also reduce the danger of brealcing.
The process in accordallce with the invelltion can also be carried out in such a wav tllat a Z or S-shaped turn is applied t() the varn in the area of the te,~turing nozzle.
In this l~ay a special ef fect can be achieved in the te:~ ~ur ed varn .
The process in accordallce with the inventic)ll also allc)ws for twisted and/or noll-tliisted fibres to be fed int~) the first delivery device. BV apDrol:)riate selectioll of the materials ~nd the nature oE i:he t~iiStill~, ~he te~tllL-~cl yarns produced can be given certain qualities, in particlllar Witll re-~ard to strength, elasticity and volume.
A device d~si~ned to carry out the 1~rocess in accordance with the inventioll is characterised irl that a false-twisting device is provided between the texturing nozzle and the second delivery device which has as a deflecting body a fr~ely rotating twiYting pin wit]l its axle at an ;
inclinatioll to the direction of transport of the yarns and a diameter larger than ~ ïnsn.
.. -The rotatahle mounting of the twisting pin avoids friction and, thus, strain on the individ~lal fibres as they pass througll the false-twisting device. The fihres can be guided in such a way that wilen they pass over the ~ -twisting pin the coil~s do not touch one another. The inclination of the ~twisting pin in relation to the direction of transport of the f ibres Prevellts the coils of varn from tonching when they pass over the twisting pln, tllus also reducing strain on the mater~al.

In the practical etnbodiment shown in Fig. 1 three untwisted threads 1 2 3 in the form of multifilaments .

2~S39~ 6 The texturing nozzle 6 is of a kno~ll tvpe of constructic~n. The threads l 2 3 passing through it are fluffed up in a knoln manner by blasting with pressurised air.
The false-twisting device 9 is equiooed witll a drive not illustrated here which turns the false-twisting device 9 rc)un-l an axle runtling in the direction of tratls~?crt.

Tlle twisting pin 13 turns in accc)rdance with the speed of transpc)rl: of t:he threads. The relative speed between the olJter surface of the twisting pin 13 on the one harld and th0 threads Oll the other is zero.

The distallce between the false-tl~lsting device 9 and the ~exturing nozzls 6 is adju~table so that the device can be adapted to suit various nualities of material and yarn derlier.

In the practical embodiment in accordance with Figs. 1 and 2 the threads 1 2 ~ are guided via the first delivery device 4 and the texturing nozzle 6 into the false-twisting device 9. The threads 1 2 3 are given a :: :

In this wav the tilre3ds 1 ~ 3 fed into the first deliverv device ~ as single strands are bound together into a c~osecl unit and in this forrn are drawn intc~ the inlet 5 of the texturing nozzle 6. The number of turns a~plied to the threads per unit of length is determined according to the characteristics of the threads selected. Fc)r this purpo~ e the nature of the rnaterial rnust be ta';en into accoun~ and care rnust be taken to en.sure that the nurnher of turns dc~es nc)t sllbject an~ of the n~aterials used to undlle strain.
The te.Yl:l~red var~l e~ner~ frorn the c)utlet 7 still has the t~ist. W]liCIl ha~ie beerl al:l~?lied to it. .~S a result of the known false tl`liSt effect the ~ arn is no lollger tl~isted after passillg over the false-twisting device and fllrtller fluffing up c~ccurs.
Arlv threads capable Oe being fluffed up can be treated witll the procei~s and the device in accordance with the invention. In particular however the processing of relatively brittle threads such as e.g. glass fibre thread.~ is posYihle since the procesi~ and device ensure that thei~;e fibres are treated in the necessarv stre-;s-f ree manner .
