Method and apparatus for dividing stabilized twisted weeds

The invention relates to the twisting of fibers ^

when spinning and is special, but not exclusive ™ borrowed, intended for spinning yarn from staple fibers, for example wool fibers. But Lie is also an invention applicable to the first process stages of "rare production" for example in the drawing processes

In the usual spinning of staple fibers, the fibers previously formed into a stretch band become several Subjected to drawing operations to produce a roving. The roving is spun into yarn by machines that pull the roving and Izor. Continuously into the roving bring in a twist, and then it's done

Yarn wound · Since in the following in particular from ύ

a procedure is spoken according to which the roving is converted into a yarn, the term roving is intended to denote the fiber mass that is fed into the spinning machine is, and the certificate of sin is denoted by iarn The most common spinning machines are the spinning capsule machines and the ring spinning machines. Jei these Maaohine species the yarn is twisted when it is wound on a rapidly rotating spindle · The xjarn gets over the end of the spindle is wound up and the spindle wears itself out significantly Rotate faster than necessary when winding

The above spinning processes also have other disadvantages, namely:

1) The twist to be introduced into the yarn is limited by the speed at which the packaging rotates.

2) The tensile forces mentioned form practically an upper one ■ Production limitation and a lower limit

with regard to the weight per Lär.-se: unit of the yarn, if you want to avoid breaks in the yarn.

3) As a result of. Balloon Parasites and Centrifugal Forces the packaging of the yarn is limited in terms of its size and type, so that usually the Twine needs to be rewound before use.

4) The entire machine must be used to replace full packs be stopped.

Other spinning processes avoid some of the disadvantages noted above, but none of these other processes has been found introduced because these processes themselves have some disadvantages. 909833/1088

4) disadvantageous for the subsequent pulling is that at the. terry the pasers disorientate. For example Such a Sntorientierung results in a subsequent panting laser breakage and an inaccurate one Deduction.

5) Rotating often results in end fractions

The invention aims at a method for producing rotated laser, in which the above: i mentioned problems do not occur and are at least insignificant. In particular the invention is intended to avoid that the receptacle packaging has to be rotated quickly in order to cause the rotation. A laser twist can then be achieved at a high production rate without frequent breaks. and the laser formation can be recorded on a packaging suitable for subsequent treatments.

As the following description refers to different types relates, such as roving, strapping, staple and continuous yarns, SInEeI and multiple yarns, The word load is understood in this way below that all of these structures or similar structures are included.

The main problem in the manufacture of turned loads is the need to bring in the twist that the load is to be wound up over the end of rapidly rotating packaging. A temporary twist can be placed in a moving shop, without the receiving packaging rotating quickly and if the rotation is allowed to occur periodically, there is a load with twisting. Such a store has alternating zones of opposite sides distributed along its length Rotation. The twist in such a load is not stable, and the twist disappears,

909833/1088

1510582

if the store is not over the length of two "neighboring Zones with opposite rotation is supported. This is explained by the following j

Let it be assumed that a thread lies between two comb play layers moved to a receiving packaging »If at an intermediate! point the thread is at his Movement is twisted, then the thread has to move backwards from Twist point, for example, a twist S, and • the thread on the other side of the twist point has a twist Z. However, since the thread is moved, the thread is moved with the twist S behind the twist point, whereby the twist Z is eliminated ™

and is inserted into the thread that lies in front of the twist point until it finally reaches equilibrium is, i.e. if practically in that of the point of twist coming thread is no longer twisted.

If the thread is not rotated continuously but intermittently, then the state in which there is no rotation is present in the thread just before the twist point not reached. The moving thread is twisted so that there is a twist S behind the twist point is, and a twist Z in front of the twist point. So a thread section is produced, which at the front |

has a twist 2, behind it a zone in which none Twist is present, and eieaSiinterar thread section with a twist S. Since the thread is moving, the section with the twist "Z" comes onto the receiving packaging. If the twisting is now temporarily interrupted and the thread runs off at the twisting point, then / the thread runs with the twist S over the twist point S to the receptacle packaging. The twisting begins again, and the thread with the twist Z is produced again and directed onto the receiving packaging, etc. So the thread coming from the acceptance packaging has alternating zones with rotations S and Z.

An example of this type of twisting is the outlet head of some hackling machine, where the Streokband is given an alternating twist before it is wrapped around the receiving packaging. Another -ßeispiel is the method described in the British ^r atent 878,671. Another example with alternating twist is the process for the production of yarn according to French patent 1 15Q 847 »in which a yarn is given an alternating twist and the twist is stabilized, namely by hardening the yarn in the heat or by application a hardening solution.

fc More example * liner show alternating twist French patent 701 689 »in which a double twist is made alternately to create a new one, of two or more Yarn to produce existing yarn »^ κΐβχ the Australian Patents 224281, 236265, 238109 and 23826§? where alternating Twists create intertwined yarns. In the latter case the rotation is stabilized by heat curing or by hardening a solution or by more or less irregularly engulfing the individual yarn fibers. There are other processes in which yarn, a roving or another laser mass is twisted alternately and the twisting is prevented, ensuring that the twisted face mass 3ο is

w is supported that the twisting ceases, for example by winding it up on a package or by inserting it into a 2uch in such a way that the fiber mass is not free over a length which is about as great as the Twist zone

In any case, when inserting an alternating Twist in a yarn this twist can be stabilized somehow, otherwise the twist of one area merges into the adjacent area of opposite rotation, and the two rotations are mutually exclusive lift. This also happens when the fibers are affected

The strands 5 run after periodic rotation in the Twisting device 7 through a guide 13 (Figs. 3 and 4) for comb play of a pair of take-up reels 14. As can be seen from FIGS. 6 and 7, the knuckles have a pair with Plastic impregnated spur gears with a V-shaped incision 15 that extends up to their pitch circle diameter The two strands fjf are extended by the pulleys 14 brought together and twisted together after passing the rollers 14, so that a stable self-twisted yarn between the rolls 14 and the receiving package 16 is formed. As previously described, the strand is stabilized by the bend of the discs · The guide 13 is consequently just a safety device that prevents accidental displacement of the stranded wire, the receptacle packaging is on a rotatable spindle 17, and the yarn is wound onto the packaging by means of a guide 18.

In the version according to Fig. 8 to 10, the pulling device is ordered 3 from rollers, and the twisting device has the form of a twisting tube 20 with jaws 21, which by the centrifugal forces be kept closed. An I-cam assembly 23 opens the jaws periodically. As Fig. 10 shows, the twist tube has a central stationary pipe 2.3 through which the strand 5 runs, and around it an outer tube 24 is rotated · The outer tube "carries the jaws 21, which contribute 25 are articulated and adjustable weights

are balanced in such a way that the centrifugal forces during rotation close the jaws. The inner tube 23 can move to a limited extent in the axial direction and is connected to an arm 27 which carries a hollow 28 at its end. The cam roller 28 runs on a crouch 29 off, and when she reaches the limp! 'Hurry 30, then the arm pivots around the ". joint 31 and moves the tube 23 forwards · This opens the jaws 21 and the rotation is interrupted. In the illustrated embodiment, the twist tubes 20 cannot be close to one another and, as a result, the two twisted strands cannot fit tightly into the Twist position are brought. Since the twist is to be retained alternately in a strand, you have to Hold the strand tightly and ensure that its greatest free length is significantly less than the length of the twist zone, and then the strands are loosened by means of a Roller chain 33,34, the rollers of which are also incised across the corners 'are brought together and through contact with the Roles held in place until a merge occurs.

The special versions of the twisting device shown in the drawings can also be replaced by reversible tubes, hyperbolic rollers or the like. Devices, which result in a periodic twist. It can also a twist according to Australian patents 224 281, 236 265, 238 109 and 238 260 may be provided. Also the pulling device may be different from what is shown, as can the take-up rollers, guides and packaging. the Parts can also be present and arranged next to one another, as with the usual spinning frames.

In the Mg.11A, 12A, 13A, yarns or other i ^ den that can be produced according to the invention are shown. According to Mg.HA

-14- 909833/1088

the yarn consists of two similarly twisted strands 35,36, which are placed in phase with each other with their zones

In the zone / ^ there is no twist, so that the twist S changed from the left to a twist Z right. In the zone ^ the twist of the individual strands also changes from the twist Z left to a twist S right. In the zone / \ ^ neither any of the strands nor the superimposed structure has any twist. This zone therefore means a weak zone in the yarn. The distribution of the twist according to FIG. 11A is shown graphically in Pig. 13B, the twist being plotted on the axis OY versus the length on the axis OX Line B represents the twist in the superimposed structure, and the a is the sum of the untwisting of the individual strands, which is proportional to the twist remaining in the two strands.

In Pig x 12Α are the twist zones of the two strands out of phase, so that a zone Jl is the strand 35 without twisting, and in the strand 36, a zone ^ without twisting, and these two zones Lieger ¹ to the left or right of the zone / \ , in which the twist changes when the structure is laid one on top of the other · Y / ie graphically shown in Fig. The line 0 represents the twisting of the strand 35, the line D the twisting in the strand 3 $, and the line B the twisting in the superimposed yarn structure If you take the yarn as a whole, there is no twist in any layer · Is in a strand in a

90 983 37 1088

If there is a twist, then there is a twist in another and also in the superimposed structure, and if in the superimposed one If there is no twist in the structure, then there is a twist, in each of the two strands · The course of the phases results in an increase in the strength of the yarn.

FIG. 13A shows a further embodiment which prevents the twisting-change zones from coming together. Here the twisting zones of the two strands are alternately long and short and supplement see When the same designations are used as in Figures 12A and 12B, there is a di® twisting change zone with JX in strand 35. in the superimposed structure with ^ and in the strand 36 with ^ · However, in the strand 35 the Z twist is shorter than the twist S, and in the strand 36 this is the other way around. This can be achieved, for example, by the length and the phase of the twisting surface on the disk 9, FIGS. 1 to 7, are selected accordingly.

With the directions of rotation as indicated in Fig. 5, the Rubber area 11 extends over more than 180, for example 240 °, and the rubber area 11Δ also extends over 240 °, but is 180 ° out of phase with respect to each other the rubber area Ti. In such a case, zones are correct

Here the yarn thickness is plotted along the axis OY and the phase difference along the axis OX achieved when the strands are out of phase with their twist zones by 120 °, and the yarn count quickly decreases to the point where the zones are completely out of phase. In the following example, the application of the invention is illustrated with reference to the production of yarn from various staple fibers. The yarns were produced with a device according to FIGS. 1 to 7 and 8 to 10. The pulling device was intended for the production of worsted yarn. As far as the examples concern other than wool fibers, the behavior of the fibers in the device should be examined, but not the greatest possible strength should be achieved.

The foregoing description illustrates the invention at the production of yarn from staple fibers.

However, the invention can also be used in other ways. For example, the invention can be used for Manufacture of rovings in the initial stages of the manufacture of staple yarn. The invention can also be used are used in the manufacture and treatment of

multi-filament continuous yarns, or also in the treatment of single-filament yarns. The invention can likewise can also be used when the yarn is given a desired thickness by adding twists with or without heat curing It is to be foreseen that wahrecheinlioh the invention also useful is during the drawing process "in the production of rovings made of staple fibers

It is known that the invention is usable in the production of show StreokbändMSttf rovings and yarns from fibers WoIl- ä · The previously described examples that yarns are prepared ana Btapelbauowolle and synthetic fibers · experiments have shown that also erfindungsgemäse yarns (AU8 Jute and can be made flat.

The invention is also applicable to the manufacture of self-twisted ones Pads in which more than two strands are united. This can be done in such a way that, in front of the position three or more strands combined with one another, or by separating self-twisted strands that have already been formed and reunited, for example by forming a multi-strand, self-twisted thread from two strands. If the multi-strand thread is to have properties similar to the threads from which it is made, then it must The phase of the strands can be maintained · But if necessary, the multi-strand threads can be changed by changing the Jhase different properties are given »

The invention is also applicable to the strength of stretch belts, that are made by other machines, too reinforce, whereby the streokbands are introduced into opim pots without twisting and without trotting. A bolche Reinforcement is particularly beneficial for stretch belts with light weight per unit of length that would otherwise not be become firm enough for subsequent procedural stages. For example, the invention can be applied to a Hoble-Känim machine can be used - by bringing the stretching tapes together from both sides of the fascine. & an achieved an essential Reduction in stretching bandbruoh when later * pulling the stretching band out of the container. J3in use the device according to the invention in Hechelmasohinen with two or more hackle heads, very strong streok bands with a light weight per unit of length can be produced will.

When the invention is used in any of these methods, each draw tape or strand of roving is twisted in an alternating manner, as was previously described for the manufacture of yarn. Hehrere in this way twisted Streckbandlitzen or rovings, for example two, three or four, be merged with erdrehungsbereichen lying in corresponding phase ^, ψ and the strands are twisted around each other. The properties of the resulting roving or streokband can be changed significantly by adjusting the thread of the twisting zones in the individual strands, and this adjustment is easy to bring about.

In the first process stages of Garnherstelluag, for example during the drawing processes, the s ^ oh can result stabilized end product of roving can be wound onto a package. This effort is simple and the aforesaid twisting or twisting devices can be omitted. With regard to the Verpaokungsgröe

The individual strands can then be fed to special inlet points in the machine, or they can be untwisted and fed back again and fed together to an inlet point on the machine. In the latter case the strands can be brought out of phase together J

A special effect has been achieved with cloths * Because the twist pattern in the yarn changes along the length of the yarn, various effects can be achieved with cloths made from such yarn by taking advantage of the fact that yarn parts are more or less random with a special twist pattern are present. For example, a very interesting pepper and salt pattern was obtained on a cloth by using a gait made of two strands with different Serbs.
