Packing made of flexible material for wireless or twistless application of the material and method of production such a pack

The invention relates to a pack made of flexible material for wireless or twistless delivery of the material that has a series of layers or plies of turns, of which each turn forms at least one figure eight and each turn has an intersection, the turns having an interior core space through the package form. Me invention also relates to a process for producing the new pack Coiling of flexible material with such a

Relative movement takes place between a spindle and a supply of the flexible material that the material is forced is to lie around the spindle in turns that each form at least a figure of eight, wherein the relative movement between the spindle and the material supply is chosen so that the crossing points of successive turns, seen in the angular direction, follow one another around the axis of the spindle, "■ * '

U.S. Patents 2,634,922 and 2,634,923 are Packages of flexible material in the form of successive turns described and illustrated in which each turn forms a figure-of-eight ligure, the intersections of successive turns in angular Successive displacements around the axis of the packing.-Such Windings are provided with a radial opening into the central inner core space through which the inner free end of the material is pulled outwards so that the wire or twist is balanced out and prevents tangling of the material and the formation of loops. With such packs the crossing points follow one another around the axis of the pack in the same direction from loe to layer, though this succession can be interrupted to form the opening.

In US Pat. No. 2,767,938, a pack is loaded

wrote, "in which a set of Kreuzurigsstellen provided is that angularly around the pack over an overall angle of less than 36o ° follow each other, then a second row generated by crossing points that follow each other at roughly the same angle in opposite directions etc .. This arrangement allows both the opening to be provided through the body of the pack and also to prevent any interference in the delivery of the material, since the length of the material between successive Crossing points in the vicinity of the opening do not have to cross or cross the opening and consequently not pulling against the packing or the tube or the sleeve. The machine on which this Packing is wound is a modification of the machine shown in U.S. Patent 2,634,918 is. This machine causes a rotating movement of the spindle and a reciprocating movement of a Padenführer which is out of phase with the movement of the spindle is or is out of phase, so that in this way the angular progression of the crossing points is produced, the direction in which these crossing points follow one another depends on whether the number the oscillations of the thread guide for the flexible material are slightly lower or slightly larger than a whole multiple is half the number of rotations of the spindle, where

these movements are called "plus" and "minus" turns According to US Pat. No. 2,716,938, the machine is designed so that it has a "plus" winding winds the spindle during a given number of rotations that are less than

^ wound with a minus turn. In this way

^; · .. ,, the types of packing described above are created. The packing described in US Pat. No. 2,767,938 has certain disadvantages which the present invention is intended to prevent as far as possible.

The principle described above, if it is not changed, creates a turn that either "'""has a very large or an open advance step (" advance ")

to produce a relatively small opening or a very large opening with a small advance step ("close advance or gain"). In any case, the effect for the tightness when winding and for the effectiveness when dispensing the yarn through the opening is disadvantageous. This efficiency in dispensing the yarn or material is adversely affected by the size of the "valleys ¹ , ¹ " which tend to be removed from the inside wall of the winding during the dispensing process

to get away. The larger and the more even this "valley" is, the greater the tendency! to get away.

The invention has set itself the task of remedying this.

The invention therefore relates to a pack flexible material, which is wound up in a so-called universal winding, with Kreuzungsstellen.in successive layers ofe layers are present, those about the axis of the pack "in opposite directions at angles less than 36o amount, one after the other, so that a radial opening is released in the inner, central core space, through which the free end of the material to the outside can be pulled so that it can be dispensed, with the turns in alternating layers in one Are arranged at a distance from each other, which is two to three times as large as that of the adjacent layers or layers is.

For the above purpose it is provided according to the invention, that in a layer or layer of consecutive Turns the intersection points at an angular offset around the axis of the inner core space in one direction, while in the next layer or layer the intersections in

angular displacement successively in the other direction lie around the axis of the inner core space that the entire angular extent the curve of each layer or layer of turns is smaller than 360 ° so that the crossing points are arranged in such a way that they form a transverse opening release, which leads through the windings into the inner core space, the inner free end of the material can be passed through this opening to the outside, and that finally the turns provided in one layer or layer at a distance from one another measured in the longitudinal direction of the pack which is much larger than the distance between the turns in the adjacent layers or layers.

The present invention modifies the above-described principle of "plus" - ^lf minus "advance, in which the goal thrust is issued over the entire winding, so that in plus layers (or in minus layers, depending on the pail), a relatively open advance is present, while with minus (or plus) layers there is a relatively small advance. In this way, the width of the opening that is achieved with a small or narrow advance is changed by the layers which have an open or large advance, and the size of the opening and the associated "valleys ¹ !" is reduced. The consequence of this is that not only the

- 7.-30985Q / 006S

222558

Winding is made more compact and uniform, rather It also prevents the tendency of wide "valleys" to get material loose on the inner wall during the dispensing process to press.

Another advantage of the "invention" is that that. Depositing material in a continuous. Parallelism around the tips is prevented, so that it becomes difficult to have a frictional effect on any rotation.

According to the invention an improved package E _r is attained, in which the opening can be made quite small and in which the "valleys" are not remarkable, and can not interfere with the discharge. The present invention proceeds in the same way as the arrangement according to US Pat. No. 2,767,938, with the exception that the distance between the successive turns or the advance is substantially greater in a position in which the intersections are in the one direction one after the other than in the adjacent ones, in which the crossing points follow one another in the other direction. The ratio of the distances between the turns can be chosen so that the distances in one layer are about 1 1/2 to 2 times as large as the distances in other layers, preferably 2-1BaI as large, but they can be even greater.

The packing produced in this way has a much less "emphasized spiral rib at a flat end, than the wraps that with the above plus minus - On winding processes of a known type are generated.

According to a further invention, the Yer-

drive for the production of the new pack characterized in that the relative movement after periods which are smaller than those in which the crossing points follow one another over an angle of 36o °, changed in such a way that the crossing points during each period in the opposite direction follow one another than in the preceding period, in which miscellaneous the deviation from a whole ratio between the relative movement of the thread guide and the spindle from that in adjacent periods and the down during a period of windings in the longitudinal direction of the spindle to dne distance apart from each other, which is much larger than the distance between the turns, which are designed in the adjacent periods.

In the drawing the winding pattern is for two consecutive ones Layers of an I & kung according to the present Invention shown.

The drawing shows a winding pattern (winding pattern)

a pack according to the invention, "in which two successive or superposed layers or layers are shown, the first layer shown in full lines with a negative advance step is wound, while the second layer shown in dashed or broken lines with a is wound up with a positive advance step. The winding is an "one" turn and for the positive or negative feed steps of a normal "on" turn the thread guide guides 3 ο turns each of the spindle in each case 29 or 31 complete oscillations.

When the spindle and the thread guide move "in step" or evenly ("in unison"), whereby the speed of one part is a multiple of half the speed of the other part, Theoretically, the successive windings would lie directly on top of one another. This is obviously impossible, and there is a sufficient deviation in the normal universal winding of this gear ratio an exactly multiple number available, so that in a shift or lay successive windings directly next to each other, while the crossing points around

progressively follow the pack around. In the plus-minus winding that is described in the USA patent 2 634 918 is the deviation

'of the gear ratio of an exact multiple

the same in each direction, and the result of this is that the distance between the crossing points is the same for both the plus and minus layers or layers. In the same way is the

>: 'Distance between the center lines of the successive turns of the layers or plies the same in all layers or layers. In the present pail

this distance becomes "advance" V called.

The distinguishing feature of the present invention over what is disclosed in U.S. Patent 2,634,918 has been disclosed is that the deviation from the gear ratio is an exact multiple and consequently the advancing step in the "plus" layers is substantially different from the advancing step in FIG distinguishes the "minus" layers or plies.

Looking now to the drawing, it must be stated that the Stellaioder points at the top * ^': side and bottom of the diagram in itself

the same distance from the sides, the same or represent similar points and therefore the same

If the machine is set for a negative advance ("negative advance"), the spindle revolves in the direction indicated by the arrow, and when the guide ("guide") moves to the right, the first position begins at a ^ , it then runs to a ₂ , it changes its direction to az and a ^ towards and so on until ago. The intersection

digits are shown at cj, C ₂ , 03, etc. It can be seen from this that these intersection points around the spindle in the direction of the rotational movement of the spindle, which is indicated by the arrow, progressively follow one another ("progressing around the spindle").

When the point ags is reached, the speed change mechanism of the machine on which the package is being wound is changed and the material now travels from bj to bp, then changes direction to b ₂ , b ^, then changes it the direction to ¹ O ^ and so on, where the crossing points such as cj and C ₂ , then progressively successive in the opposite direction and the distances between the crossing points about twice as large as between the crossing points ^v c- |, C ₂ , C3 are. As can be seen, grooves or depressions are still forming, as in the known arrangements, although they are no longer so noticeable.

In addition, these grooves leave an opening free at h through which the inner free end of the Material can be pulled out of the package.

It can also be seen that in the embodiment shown, the distance I ¹ measured in the longitudinal direction of the package axis between successive windings of the second layer or layer is approximately twice as great as the distance 1 between the successive windings of the first layer.

In the embodiment shown in the drawing are approximately 22 oscillations (back and forth movements) of the Jadenführer ("guide") for 21 revolutions each the spindle provided at the position or layer indicated by solid lines, and in the case of the layer drawn with broken lines, approximately 11 oscillations are provided. When running of the invention in practice, such a condition may exist, but the fact is that this condition is named more for the sake of clarity, because in practice the windings of both layers or layers are much closer together than shown. The fact is that if one is on a condition goes out, after which the successive Windings or turns of a layer or layer

Lying side by side, e.g. with 179 Mn and backward movements of the thread guide at 26o revolutions each time the spindle in each direction, which is the number required for the successive laying of windings or turns side by side in each layer or tier is on the plus side, and accordingly on the minus side with 18o movements, and if one of these numbers (179) is kept unchanged while the other is around one a small amount is changed, e.g. to 186, a distance between the successive windings or turns of the second layer or ply is obtained which is substantially larger than that in the first Layer 'or ply is, while the pack ^ is proportionate will be compact and the depressions, grooves or "valleys" etc. with their harmful effects will be essential will be reduced.

The invention is applicable to both compliant or relatively rigid, flexible materials such as wire, cable and Hoses can be used as well as for textile materials, e.g. Yarn,! Threads, ropes, cords, etc.
