Device for stranding single strands
with reversing stroke

The innovation relates to a device for continuous Stranding of single strands, such as veins, wires and the like, with reversing lay into one |. Molding strand. The device consists of a stranding nipple, an oscillating memory and a trigger.

It is known, single strands with reversing stroke

as described, for example, in US Pat. No. 3,169,360

to be led. The stranding of the individual strands to form the form strand takes place in such a way that the individual strands to be stranded follow Go through doi * perforated disc has been stranded, namely through dns Rotioron dos Speicher or the cradle; who rushed ahead Form strand is now the turn next to the turn only in the Wiogo located drums or Rndsh'tzo fInachonzugnrtig wound up until the store is full and at the beginning dos stranded form strings appear at the output of the storage tank. At this moment the direction of circulation of the memory must be changed so that the versoilto formrstrong dos The storage tank is not unseeded again »At the same time, the direction of the threading changes at the inlet of the storage tank, and nm The output of the memory is the stranded continuation line switches' * the fixed trigger and the accumulator twisted again, like a double twist. The new direction of circulation of the store is retained until the reversing point the stranding appears at the output of the accumulator; then the direction of circulation of the memory must be changed again. As can be seen, the distance between the reversing points depends on the storage capacity of the store.

Now there is a desire to be able to produce stranded form strands in which there is as great a distance as possible between the reversing points. This is due to the fact that the presence of the reversing points when the stranded strands are cut into lengths they should not have any reversing points, since otherwise _p, especially with a short distance of the reversing points - for example at a distance of 50 m - »a high scrap, which is undesirable is, can result.

Attempts have therefore been made in the known Speichersrverseileinrichtungen to increase the storage capacity, and zvrar by increasing the drum or wheel diameter and by increasing the drum or wheel spacing. the

Storage capacity could thus be increased; it showed, however, that the rotating masses at a Such an increase in the storage capacity increased, so the oscillation frequency of the cradle should be reduced had to, which led to a slower production speed.

The solution to this problem - increasing the storage capacity without increasing the rotating masses - is now new ":: ^ egesii £ ii thereby »rrpicht. that coaxial with the stranding axis and an oscillating around this axis serving as a memory Winding body and are arranged on both sides of this guide members, which the shaped strand on or from the WikkolkÖrper wrap and have an opposite sense of purpose. Furthermore, funds are available around the turns wound at one end of the bobbin to the other end of the winding body and the reversing point located on your winding body axially to be moveable »

Due to the winding body arranged coaxially to the stranding axis you get a compared to the known devices much larger storage capacity without the circulating hatreds are magnified; due to the coaxial arrangement of the winding body and guide members and their Oscillation around the stranding axis actually results much more a reduction in the rotating masses compared to the known facilities. In addition, according to the innovation Establishment has the advantage that the Forrastraiig veniger often deflected and thus a possible hardening of the Copper and thus a reduction in conductivity is prevented.

Further details and advantages of the new facility will be explained in more detail using a figure that appears in sura Part of a Schenwitischer representation shows an embodiment.

In the figure, the bobbin is denoted by 1 and the guide J ₅ Uedcr are denoted by 2 and 3. For example, a fixed perforated disc is arranged in front of the nus of the winding body 1 and the guide members 2 and 3 in the direction of passage in front of the accumulator. The trigger and the take-up device, which are arranged downstream of the store in the direction of passage, are not shown.

The winding body i now consists of at least one of the innovations two endless straps 5 and 6, the ura respectively a pair of rollers 7 and 8 arranged on an axis parallel to the stranding axis are looped and which are arranged in this way are that the plane perpendicular to the center line of the tape with a plane passing through the threading hole Radial plane coincides. A roller of the roller pair 7 and one of the roller pair 8 are driven so that the wound on the end of the bobbin on the perforated disk side Windings are fed to Ev.de on the fume cupboard side, · * »Ο they can be processed again. The largest The storage capacity of the winding body is obtained by twisting formation of a large number of circumferential belts, which then, in the Extreme case, result in a cylindrical bobbin that the largest possible winding area according to length and diameter has predetermined bobbin.

When stranding with a reversing lay, "as he did before" thinks a reversal of the circulation when the accumulator is fully wound Sense of the memory are made so that between the stranding disc and the memory through the rotation the impact applied by the memory is not eliminated again. This means that the bobbin 1 of the call

Form strand 9 singly in one and then in another, wound in the opposite direction to the previous one is, for example, first clockwise and then counterclockwise. A reversing point is thus obtained on the winding body 1 10, which migrates along a surface line from one end to the other of the winding body 1 during the stranding. Since the winding direction of the shaped strand changes at this reversing point 10 on the winding body 1, this is Point unstable with regard to its position sum winding body 1, so that it is necessary to fix its position on the winding body 1. This is most conveniently done by that on one of the endlessly rotating belts 5 and 6, two perpendicular to this, standing pins 11 and 12 with a Distance corresponding to the distance between the reversal packages of the stranding are attached. To these pins 11 and 12 can be then, when reversing the direction of rotation of the winding body 1, lay the shaped strand 9 around, so that behind it in the direction of passage advancing pin a direction of rotation corresponding to the direction of rotation and in front of the pin a winding direction opposite to the previous one results.

The guide links 2 and 3 can be constructed differently, for example as an arm with or without pulleys, ols disc segments and the like. Has been beneficial with regard to the drive of the guide members 2 and 3, the shape of a disc 13 has proven to be close to its circumference a hole l'l and the one on the winding body side facing the molding strand to the bzi *. from the bobbin has leading nose 15. To drive the disk 13, it can have a ring gear on its circumference;

ο

The length of the disc can be about three to about 120 gear wheels positioned in one plane are carried out been, with a gear frictionally with a

Drive motor is coupled. With such a structure the winding body is mounted centrally in the pulleys and can either be driven via a planetary gear or Via a roller which is arranged axially parallel to the winding body and is coated with a rubber covering or the like and is pressed against the bobbin. The drive of the guide members and the winding body is expedient via a motor and continuously variable transmission.

The desired lay length can be set by varying the circumferential speed and the Uiclaufsimses of the guide links, by varying the speed difference between the circumferential guide links and the winding body tins their inalaufsimi to each other kaxm the throughput speed can be changed, the desired values can be calculated or, which is more favorable in many cases , can be determined empirically.

Because when a stranding nipple is present, the individual strands are often while going through this damage are exposed, it is advisable to have one on the guide members 2 and 3 on the side facing away from the winding body 1 to arrange on its circumference the roller 16 tangent to the stranding axis, which takes on the function of a stranding nipple.
