The present invention relates to a process and means for spinning and twisting natural and synthetic yarns. These process and means which may be broadly used and notably in spinning and twisting frames are also applicable to cabling or a similar operation.

The main object of the invention is to provide a process for passing the yarn for rotary spinning and twisting members wherein the yarn is caused to pass, before it winds on the rotary spooling or similar member, in sucha manner that it is applied on the yarn or thread already Wound on said member in the zone on which the winding occurs and then on said member or on the yarn or thread already wound on the latter in the zone diametrically opposed to that on which said winding occurs, said last application being effected on a diameter less than the diameter on which the first application is effected. Moreover, the yarn tension is regularized by effectin these successive yarn applications on the bobbin in planes positioned below that in which the yarn is wound on the bobbin or similar member.

According to a preferred embodiment of the invention utilizing a spinning flyer of known type, the latter has perforations or the like so arranged that the yarn, after frictionally engaging .the outer surface of the spinning flyer and before it winds on the rotary spooling member, is caused to pass on the yarn already wound, with a certain pressure along a convex path, then through the wall of the spinning flyer and back on the yarn already wound on the diametrically opposite side of the rotary member, again with a certain pressure and according to a convex path, subsequently anew through the wall of the spinning fly-er and finally back againto wind itself on the spooling member.

This invention is not only applicable to devices of the so-called spinning flyer type but also to similar arrangements of the types now in use and notably:

(a) To flyers which in this case will be pro-1 vided with perforated end blades for passing the yarn as disclosed above;

(b) To rotary ring travellers;

(c) To fixed ring travellers and other similar members.

The perforations for the passage of the yarn in the spinning flyer or the like may be made to open sidewise through a groove or slot conveniently inclined for introducing or extracting the yarn, these perforations being located in the same plane or in different plane's suitably spaced apart. V

The rotary spooling member, such as a spindle or like member effecting on the latter or units bobbin the desired spooling action, may consist of a drivin member while the spinning flyer or similar device effecting the twisting and the relative drag in angular velocity for the spooling and exerting the tension on the yarn are merely braked. Reversely the spinning flyer or similar member adapted to twist the yarn maybe a driving member while the spooling member, for instance a spindle or similar member, which effects the yarn spooling and tensioning action is merely braked.

According to a further embodiment the. braking of the spooling member may be obtained in suitable conditions, i. e. in accordance with the variable spooling diameter, by the action of the yarn passing on the portion already wound.

Similarly, the spinning flyer may be fixed or mounted freely on a ring member rotating freely in relation to the vertical alternating motion device of the spinning or twisting frame and in this last case the spinning flyer is connected to the rotary ring by means of at least three parts in sliding engagement with the ring.

With the novel process and means for passing the yarn according to the invention the driving of the rotary members is materially facilitated and more flexible, the yarn is subjected to a substantially uniform tension with a constant brak ing in spite of the varying spooling diameter, the

risk of breaking the produced yarn is less, piecings are made easier and spindle velocities are greater and their production is increased correspondingly. v

The invention extends also to other specific features which will appear from time to time in the following description in connection with the afi'ixed drawings given solely by way of ex- Figs. 8, 9 are perspective views of the front and back portions of a spinning flyer according to the embodiment of Figs. 3 and 4 adapted for operation in both directions of rotation.

Fig. 17 shows a modification in the embodiment illustrated in Fig. 11.

:Referring to Figs. 1 and 2 the spindle has removably fitted thereon according to the conventional method a bobbin 2 of the type having successively superposed tapered layers. 'The spindle! may rotate for instance in' the direction of the-arrow 3. As indicated above the direction of rotation may be the reverse as well. The yarn 4 is wound on bobbin 2 by means of a spinning flyer 6, said spinning flyer or the spindle beingconnected to the copping motion in the conventional manner.

.During the rotational movement of spindle I, the path of linear displacement of yarn from balloon 4' where it is s'ubmitted to a tension t1 towardbobbin Z is as follows:

I (1) Through peripheral perforation 5 of spinning 'Iflyerlt (2) Thr0ugh perforation l .of said spinning flyer, whereby a peripheral frictional engagement igproduced at an angle a which induces a smoothing effect, while the yarn which emerges from said perforation l is submitted to a tension tzgreater than t1;

(3) Across spinning flyer '6 into perforation 3, the yarn which passes between perforations l and B bearingon a layer .of the yarn already wound on the bobbin 2 according to an'arc of a circle A centered on the. spindle'axis and having adiameter D1;

(4) Through perforation 9 of said spinning flyer, whereby a peripheral frictional engagement is produced at an angle 6, while the .yarn which emerges from said perforation .9 is submitted to a tension is greater than 752;

.. 5) Again across spinningfiyerfi into .perforation ID, the yarn which passes betweenperforations 9.and iflzbearingon-a layer 'of the .yarn already wound on the bobbin' 2 accordingtoan arc of a circle B centered on the-spindle axis and havinga diameter .Dz. lessthan D1, said-arc B being substantially diametrically opposed to the are A with respect to the spindle axis;

(6) .Through, perforation of. said spinning flyer, whereby a peripheral frictional en agement is produced at an angle whilethe yarn which emerges from said, perforation ll;is.submitted to a tension t4 greater than ;..andzfinally wound on bobbin.2 at a point ,C,-winding. 1Q0int, located on the samev side ofbobbin 2 asthexfirst arc of a circle.

Said various perforations or apertures 5, 118, 9,

I0 and l i open laterally for allowing the; yarnltobe placed in position or removed. The distribu-V tion of said perforationson the. spinninggfiyer-is soeffected that theparts ofz-the strand :QXtEIIds-gYfil gent strand consisting in rotationally driving 4. ing into said flyer would follow a path forming an angle less than between the inlet and outlet perforations if said strand was applied against the bobbin. In the example shown in the various figures, such a result is obtained by respectively locating the successive inlet perforations, such as 1; Sand ligand the'successive outlet perforations, such as'a and 10; in substantial diametrical opposition, the shortest distance existing between the corresponding diametral planesi'oflocation'ibeing less than the diameter .ofthe bobbin. .Breferably the inlet perforations for the parts ..of the strand passing in the windingzonehaveapommon lateral opening, such as perforations 1 and II (Fig. 1).

;Thus,.perforations I, B of spinning flyer 6 are included in a horizontal plane PI located below thehoriz'ontal- 'pIaneP2 containing the next perforations], l0 and II of the yarn path. The horizontal plane Pl containing the yarn strand directed to the inside of spinning'flyer Girom perforation! to perforation 8 is therefore located at a level below [plane P2 which containslboth strands from perforation 9 to perforation ID and fromperforation lfltoperforation II.

Owing to the bobbin formation firstlyconsidered, using superposed tapered layers, it automatically follows that the diameterDl of a layer in. relation to thelower plane'iPlthas a numerical yaluehi'gher than the diameter. D2v ofa layer'dn relation to the upper, plane' P2.

Let Q=momentaryspeed-of rotation of'spindle- I and bobbin 2; V L=momentary -linear output' of the feeding "cylinders; i w =momentary 'speed of *rotation of spinning flyl er '5 corresponding to diameter D! (plane -P w =momentary speed 'of rotation ,of spinning fisz er -6 correspondingto diameter DZ "(plane I? .We know .thatthe angular. .deceleration. of :the spinning flyer with respect to theflbobbinis. equal to'the ratio existing-between the linear output ;L of .the feeding cylinders and the .linear winding speed at .the level where said z.,winding occurs, whereby:

Now, fore-themomentary-spoofing on the real momentary :spoolingi diameter 'DZ corresponding to plane P2 containingperforations 9, lll=and=H the .realrmomentary spooling speed -w is lower than the :momentary speeds of --'the-'i-mpiilse whichxassistsrotation, corresponding to the: retation-assisting momentary diameter Di'cor-respending to -plane PLcontaining the other perforations r! r and. 8.

Thus, through the medium of: thestrandsubjected to a tension $3- from' perforation! through the. insidesofspinning flyer (is torperforation 3* the rotation of the spinning flyer will be materially assisted-as well;-as-,. of course; the rotation of. the ;rotating.rmembers fast therewith.

In .short, this-strand will. notably assist vthe tangent strand: from. perforation l I "to the ..momentary point at which the yarn. is being-wound on the bobbin-.in-the work assigned to; this; tanhand, of the angle at which the spooling layer;

is tapered.

4 Referring to this taper it should be noted that: (1) In the hitherto considered bobbin formation by superposed tapered layers and at the beginning of this formation the conical shape of the tube itself, although its angle is much smaller than 0, will be operative but with less importance;

When it is desired to obtain the same efficiency as that of the layers which form the body of the bobbin, a tapered-base tube having an angle 0 and of conventional commercial type may be used.

(2) In the bobbin formation by superposed cylindrical layers a slight taper provided on the bobbin combined with a distance H greater than H gives a contribution in the rotation of spinning flyer 6 or similar member.

The yarn strand which passes inside spinning flyer 6 from perforation 9 to perforation l0 and is subjected to a tension t3 will cooperate with the previous strand in assisting the rotational drive of spinning flyer 6 by the tangent strand. Thus, yarn breaking factors are further reduced accordingly.

Besides, the yarn tension is very substantially regularized in spite of the variation in the momentary spooling diameter of the bobbin tapered layer while a constant braking action is used.

Finally, this novel passage of the yarn produces designedly a pair of yarn triangles within the spinning flyer 6. As a consequence thereof and owing to the convenient angular arrangement of perforations 1, 8, 9, Ill and H the composition of the resultants of tensions t2, t3 and t4 acting in operation upon their relative strands and directed toward the axis of symmetry my are much improved. The causes of vibration of spindle l and bobbin 2, and other revolving memb ers are materially reduced.

With this double triangulation the application of yarn from perforation 1 to perforation.

8 occurs on the zone which coincides with the winding of this yarn on the bobbinbut not on the opposite zone. I

In the foregoing perforations 1, 8 only were contained in the lower plane Pl, which is in accordance with Figs. 1 and 2.

In Figs. 3 and 4 the lower plane Pl contains also perforations 9a and Illa which follow perforations 1a and 8a in the path of yarn 4a.

In order to isolate from each other theplanes PI, P2 in which the yarn is passed a rib l2 may be provided on the spinning flyer 6b as shown in Fig. 5. Of course, this rib is intersected by the yarn passage slots shown in Figs. 1 and 3. These slots are oblique to the axis my, communicate with the perforations and facilitate the passage of the yarn. The perforations are splayed out and polished .in order to avoid dragging the yarn along its linear travel in relation to the spinning flyer.

The above-described yarn passage is applicable in the same manner to any type of spinning flyer utilisation and whether rotation is clockwise or anti-clockwise. It applies also to orsimilar member-providing a combined twisting and spooling action. 7 1

The yarn 4e fed from the feeding cylinders 39 is passed through a yarn-guide 40 and an eye ing the spinning flyer during the operation of the spinning-frame.
