Definitions

  • the innovation relates to a winding support for the treatment of threads or yarns with two end rings and a plurality of elements forming a perforated sheath ring, elements which form elements connecting the intermediate rings and which are arranged in the sheath ring are provided.
  • Winding carriers of the type described above are widely used and have proven their worth. Depending on the application, a wide variety of deformation requirements are placed on such winding carriers. Winding carriers of the known type can be cylindrical, conical or biconical. Depending on the application, they must be rigid or axially flexible. Radial flexibility is also sometimes required. It can also be expedient that such winding carriers are designed to be axially flexible with a mandatory radial movement. They are sometimes both elastically and plastically deformable.
  • the structure of the winding carrier in particular with regard to the design of the intermediate rings and the webs, is different, in adaptation to the desired deformability.
  • DE-PS 1 760 818 has disclosed such a winding carrier of simple construction, which is easily deformable both radially and axially.
  • An example of an axially compliant winding support construction can be found in DE-AS 23 63 250.
  • winding carriers of the most varied of structures are known, which are adapted to the desired deformation.
  • Such winding carriers are preferably molded from plastic using a suitable tool.
  • tools for the formation of winding supports of known structure have the disadvantage that the mold must have more than two mold jaws so that after the molding the tool parts can be moved apart and the molded part can be removed. This makes the tools very expensive and, if several winding carriers are to be formed in one molding process, also very large.
  • the innovation is based on the task of proposing a winding carrier which can be shaped with a two-jaw tool and which can still be varied in structure if such a tool is retained, that all known, desired Verfor tion properties can be achieved.
  • this object is achieved in that all spacer elements have sheath lines of the same direction. These rectified jacket lines represent the direction of displacement of two mold jaws, so that the winding carrier can be easily produced from such a molding tool due to the rectifier jacket lines of the spacer elements.
  • the spacer elements for producing "certain deformation and elastic properties of the winding carrier can be designed in a variety of ways, as long as they only meet the condition that they all have the same sheath lines, which is the only way to create such a tool for shaping the winding carrier .
  • a two-jaw mold has only one parting plane
  • the presence of this parting plane results in an interesting embodiment of the invention, according to which on a first cutting plane along a diameter line (i.e. along the parting line of the two jaws in an opposing arrangement and exactly one below the other) between two elements forming intermediate rings or such an element and the associated end ring, a spacer element with a surface line parallel to the cutting plane is arranged and that further spacer elements are provided with surface lines that lie in cutting planes that are pivoted 90 ° out of the first cutting plane relative to the latter.
  • the latter distance elements lie with their Sheath lines so as already described above, while the former spacer elements are on the one hand exactly below each other and on the other hand in the parting plane of the two jaws, so that the separability of the tool is not influenced by their changed arrangement, but achieves a different design with a different deformation behavior of the winding carrier can be.
  • the spacer elements are rigid in the axial direction. This also results in a desired deformation behavior of the winding carrier for certain applications. reached. Are all distance elements elements strictly arranged one below the other, a rigid winding body is achieved while, when these spacing elements which are rigid in the axial direction are offset in the different planes, a winding carrier is achieved which is both axially and radially flexible.
  • Another embodiment of the innovation provides that all spacer elements, with the exception of the spacer elements which are assigned to the first sectional plane, are rigid in the axial direction, while the spacer elements associated with the first sectional plane are alternately rigid and soft in the axial direction.
  • This arrangement is particularly advantageous if the rigid spacer elements are arranged offset in the planes.
  • the winding carrier is then particularly soft in connection with the alternately rigid and soft spacer elements of the first sectional plane, both in the axial and in the radial direction.
  • the spacer elements assigned to the first sectional plane are designed to be soft in the axial direction in each case in the planes with the rigid outer spacer elements. As a result, a uniform deformation of the winding carrier is achieved both in the axial and in the radial direction.
  • the spacer elements are at least partially designed as boundary surfaces of hollow bodies that are open at least at the outer end.
  • pure axial deformability can be achieved be, the deformation force of the shape and the
  • Wall thickness of the hollow body is determined.
  • the size and force required for the axial deformation can therefore be determined by the dimensioning of these boundary surfaces and the formability of the winding carrier is still retained using a two-jaw tool.
  • the winding carrier as a whole, for example, can be made firmer in the core area and more flexible in the outer area.
  • the winding carrier can still be produced with a two-jaw molding tool.
  • spacer elements are assigned to the first sectional plane, at least according to claims 1 to 6, whose surface lines can converge, diverge or run parallel to one another in the direction of the interior of the surface ring.
  • This makes it possible to combine the hollow bodies as spacer elements with the flat spacer elements, as a result of which different deformability of the winding support can be achieved in different axially lying planes of symmetry.
  • the manufacturability of the winding carrier by means of a two-jaw Mold not affected.
  • Another refinement of the innovation in turn provides that ring segments are provided between the intermediate rings in an arrangement lying opposite one another on the winding support and with the first cutting plane as a plane of symmetry, which are carried by spacer elements.
  • ring segments are provided between the intermediate rings in an arrangement lying opposite one another on the winding support and with the first cutting plane as a plane of symmetry, which are carried by spacer elements.
  • gaps between the intermediate rings of undesirable size occur in the areas mentioned. The proposed measure reduces these gaps to the desired extent.
  • a supplementary embodiment of the innovation in turn provides that the intermediate rings have different diameters in a continuous sequence and / or in periodic alternation. This also makes it possible, while maintaining all previous possibilities, to design a winding carrier which is not only cylindrical in its essential shape, but which is also conical, biconical or e.g. can be sinusoidal. These forms can also offer very specific advantages when treating certain fibers.
  • the innovation proposes that in the same orientation as at least the spacer elements, which are not assigned to the first sectional plane, at least at the outer end open hollow bodies are molded into at least several intermediate rings, so that the intermediate rings in the circumferential direction of these Hollow bodies are interrupted.
  • a two-stage behavior of the winding carrier can be achieved with respect to the desired deformation directions.
  • the deformation path of the elements originally intended for the deformation is exhausted, and an additional deformation path, as described above, can be used as required, depending on the external circumstances, for example for safety reasons.
  • This additional possibility of deformation can be exploited separately in the axial as well as in the radial direction, or can be used in a combined manner.
  • the hollow bodies which interrupt the intermediate rings can be connected to the corresponding hollow bodies of the adjacent intermediate ring and thereby form the spacer elements.
  • At least the spacer elements carrying the ring segments have an inward folding, so that each ring segment is displaced inward when the adjacent intermediate rings move axially. This design creates space very quickly for tightened wound fibers.
  • the inner lateral surface of the winding carrier with the exception of the end rings, at least partially, has an oval cross section extending in the direction of the first cutting plane. It is possible that certain spacer elements protrude inward beyond the inner circumferential surface when they are deformed, so that the winding tube would jam on the dye spear in such a case.
  • the ovality described in connection with the particularly directed shape of the spacer elements creates the necessary space here without the guidance of the winding carrier on the dye spear being lost.
  • the spacer elements at least partially have predetermined kinks.
  • the avoidance direction of the spacer elements can be predetermined while maintaining all previous advantages.
  • the predetermined kinks can run in the direction of movement of the two mold jaws of the tool for the manufacture of the winding carrier, so that this measure also does not impair the manufacturability of the winding carrier according to the invention by a molding tool already described.
  • the spacer elements are straight, oblique, kinked, bent in a C, 0 or S shape. All of these are shapes for the spacer elements with which a desired deformation behavior of the winding carrier can be achieved and which nevertheless allow the use of a two-jaw molding tool in the arrangement according to the invention for the production of the winding carrier.
  • the elements forming the intermediate rings are straight, kinked, wavy and / or provided with predetermined kink points. These measures can also influence the deformation behavior of the winding support according to the invention in the desired manner without other advantages being lost.
  • the body of the winding support on one side an end ring with an inner centering for a dye spear and an outer centering for a next end ring and on the other side an end ring with a centering for the outer centering of a preceding end ring.
  • Another embodiment of the innovation provides that all spacer elements are alternately rigid and soft in the axial sequence to the winding carrier. This is a particularly simple way of producing different deformation behavior in zones, without this having an adverse effect on the demouldability during manufacture by means of a two-jaw molding tool.
  • Another embodiment of the innovation does not provide that all spacing elements of a plane with dn Spacer elements of adjacent planes lie in the same axial section planes. Such an arrangement relieves the strain on the intermediate rings and nevertheless enables an axially rigid, as well as an axially, both overall and only zone-wise, soft winding carrier to be built.
  • a thread reserve groove is formed in at least one end ring.
  • this thread reserve groove can advantageously also be molded in at the same time without problems, even with a two-jaw molding tool.
  • the spacer elements at least in their connection area, have a width that decreases from the outside of the winding support.
  • Winding cores as they are known in the most varied of shapes and with the most varied deformation behavior in the prior art, can only be produced from thermoplastic materials by means of molds adapted in terms of their divisibility. In this way, however, it is possible to give the winding tube such a structure that a desired deformation behavior of the winding tube is achieved during its use. The necessary, very expensive molds are disadvantageous.
  • winding cores were also made with a four-jaw tool.
  • the tool is already cheaper, but is still difficult to design because of the multiple separation for large quantities, because a separation into two levels must take place.
  • such a simplified tool has only been used with a very simple winding tube.
  • FIG. 1 and FIG. 2 show a winding support which is rigid in the axial and radial directions.
  • This winding support is constructed by a plurality of intermediate rings 32 arranged one above the other and delimiting planes 45, which are kept at a distance by spacing elements 7 arranged in planes 45.
  • the spacer elements 7 are each arranged in the same axial section planes 47 and are all aligned in the direction of these axial section planes 47, so that they have sheathed lines which are rectified in this alignment direction.
  • These spacer elements 7 are therefore all in planes 47 arranged parallel to one another, which subdivide the winding carrier in the manner of a disk in the axial direction.
  • the surface lines 37 are therefore such that a molding tool, not shown, in the first cutting plane 33 is separable and can be moved together or moved apart perpendicularly to this first sectional plane 33, all spacer elements 7 extending with their surface lines 37 in the direction of the movement of the two shaped beacons.
  • the end rings and the intermediate ones are not shown in detail.
  • a jacket ring 36 is built up.
  • the arrangement of the spacer elements 7 described leads to the jacket ring 36 having a free area on both sides next to the outermost spacer elements 7, which may be undesirable.
  • spacer elements 8 or 9 which, however, are oriented in the direction of the first sectional plane 33, as can be seen in FIG. 2. Since these spacer elements 8 and 9 lie in this sectional plane 33, which at the same time represents the parting plane of the molding tool, the winding carrier remains producible from a tool with a single parting plane, despite the changed arrangement of these spacer elements 8 and 9.
  • ring segments 31 can now be arranged parallel to the intermediate rings 32 for space adjustment and, if desired, for further support in the side areas mentioned, which are then held in each case by the spacer elements 8 and 9 and the first adjacent spacer elements 7.
  • the interior 35 of the casing ring 36 is filled by a so-called.
  • Dyeing spear that can use the inner surface 29 as a guide surface.
  • the first sectional plane 33 it must always be ensured that the main directions of the alignment of the spacer elements 7 or 8 and 9 are each rotated by 90 ° relative to one another, in the first sectional plane 33 only a single row of spacer elements 8 or 8 arranged exactly one below the other 9 may be present, while the remaining spacer elements 7 pivoted through 90 ° in this pivoted position may all be parallel to one another, but may also be arranged offset to one another.
  • Figure 3 shows the winding carrier in the undeformed state.
  • the intermediate rings 32 are held at a distance from one another by spacer elements 10 aligned in the manner described, but these spacer elements 10 are arranged offset to one another in the circumferential direction of the winding support.
  • spacing elements 11 and 13 or 12 and 14 are alternately arranged with one another.
  • the spacer elements 11 and 12 are preferably rigid, as are the spacer elements 10, while the spacer elements 13 and 14 are deformable by an axial load. It is hereby achieved that in the case of an axial deformation, a radial deformation also necessarily occurs, as shown in FIG. 4.
  • FIGS. 5 and 6 show a variant of the embodiment according to FIGS. 1 and 2.
  • the spacer elements 15 according to FIGS. 5 and 6 already have a pre-bent shape, but that runs opposite each other on both sides of a plane of symmetry perpendicular to the first sectional plane 33. This causes the spacer elements 15 to buckle when the winding support is axially deformed in a predetermined direction.
  • spacer elements 17 in the first sectional plane 33 in the same orientation and deflection as the spacer elements 15.
  • rigid spacer elements 16 can also be arranged there.
  • the spacing elements 15, 16 or 17 are all located within the casing ring 36, a so-called inside 35 of the casing ring 36 again.
  • Dyeing spear can be arranged.
  • the surface lines 37 of the spacer elements 15 and 17 again run parallel to one another, in such a way that they run in the direction of the displacement movement of the two mold jaws of a molding tool which is separated in the first cutting plane 33.
  • spacer elements 16 can also be provided, the surface lines 38 of which then run parallel to the first sectional plane 33, so that a separation of the tool for the production of the winding carrier is not disturbed in this plane.
  • FIG. 7 shows a winding carrier, the spacer elements 18 of which have the shape of cylindrical tube pieces which are placed between the intermediate rings 32 and whose orientation is such that the section line 39 of the planes of symmetry 40 and 41 of these spacer elements 18 is again arranged in the direction of the separating movement of the two mold jaws of the mold, all of which then Section lines 39 are arranged parallel to each other.
  • flat spacer elements 18 can also be provided in the first sectional plane 33 within the casing ring 36. This combination can also achieve the desired deformation behavior of such a winding carrier in certain cases.
  • FIGS. 7b and 7c A supplementary variation is also shown in FIGS. 7b and 7c, in which the spacer elements 18 have inner surface lines 37 or outer surface lines 42 'which run in the direction previously described, while these spacer elements 18 according to FIGS. 7b and 7c have outer surface lines 42 or have inner surface lines 37 'which. diverge towards each other in the direction of the interior 35 or the exterior 35 'of the winding support. This makes it possible to achieve a greater resistance to deformation in the inner region than in the outer region, and yet separate mold jaws can only be used in one plane.
  • a winding carrier with an alternating cross section of the body 1 can also be easily produced from mold jaws which can only be separated in a single plane.
  • the intermediate rings 32 "determine in their Diameter the cross-sectional profile of the body 1 of the winding carrier.
  • an end ring 2 is formed on the body 1 in FIG. 8, which has both an inner centering 3 and an outer centering 4. With the inner centering 3, the body 1 can be centered, for example, on a dye spear.
  • an end ring 5 is formed with an inner centering 6.
  • the next body of this type, with its outer centering 4 of its end ring 2 then located below, can be inserted into this inner centering 6 of the end ring 5. It is then kept and managed safely.
  • the end ring 5 can also have a thread reserve groove 46.
  • FIG. 8 shows a winding carrier, which is equipped with spacing elements of different types in axial sequence. These can be integrally formed on a single winding carrier, but they can also be present in a single version on a winding carrier.
  • the spacer elements 18 ′ and 26 represent variants of spacer elements that can be deformed in the axial direction.
  • the arrangement shown further below has spacer elements 7 ′′, which combine various intermediate rings in groups.
  • the spacer elements 7 ′′ are offset from one another in the circumferential direction. This arrangement enables axial mobility with forced radial mobility, but the winding carrier essentially only creeps into one another in its inner region, while its outer axial dimensions deform much less. Another one Behavior may be desirable.
  • open hollow bodies 34 in the form of, for example, tubular pieces are molded into the intermediate rings 32 ', but are kept at a distance in the first sectional plane 33 (not shown here), for example by axially rigid spacer elements 8' or 9 ' .
  • rigid spacer elements 7 ' are also provided in the axial direction, which are arranged one below the other in the exemplary embodiment according to FIG.
  • the axial direction is also rigid.
  • Figure 10 also provide spacers of the type and shape and arrangement described so far, so that, for example, a two-stage deformability of the winding support can be achieved. It is then possible, if the originally intended deformability is not sufficient in the respective application, that the winding carrier additionally deforms, for example in a plane as described in FIG. 10, when a certain force is exceeded, so that the wound material is damaged or the coloring is incorrect can be prevented.
  • FIGS. 11 to 13 show a similar embodiment to that already described for FIGS. 5 and 6.
  • the intermediate rings 32 are kept at a distance from spacer elements 19 and 20, which are arranged pre-bent on both sides of a central plane perpendicular to the first cutting plane 32 in the manner described, their deflections being directed toward one another on both sides of the plane described.
  • the spacer elements 21 and 22 which, together with the spacer elements 19 and 20 which are closest to the inside, carry the ring segments 31.
  • FIGS. 14 and 15 show simplified forms of the winding support according to FIGS. 11 to 13, in which the ring segments 31 are missing.
  • spacer elements 25, 26, 27 and 28 are provided which are preformed and provided with a predetermined kink 43. This causes deformation of these spacer elements in a predetermined direction achieved.
  • elements of the winding support may be formed in the parting plane, and only in this one plane, the main extent of which is pivoted by 90 ° with respect to the main extent of the other elements, because the arrangement of such elements in the parting plane does not hinder the separation of the tool.
  • All wishes for the deformability of such winding carriers can thus be met with a tool with only one parting plane for the mold jaws, so that it has been possible to propose shapes that can be produced with a very simple tool while maintaining all the desired advantages, thereby simultaneously for the first time, it is possible to design winding carriers of the most different shapes for a wide variety of requirements, which can nevertheless be produced with a single or multiple two-jaw mold, because only a single parting plane is required. Although a large number of such winding carriers can be formed at the same time, the necessary molding tool remains relatively small and inexpensive.
