Definitions

  • the invention relates to an axially compressible winding support for receiving threads or yarns with ring elements running parallel to one another, which lie in a common cylindrical or conical winding surface and are coupled to one another by deformable connecting webs.
  • Compressible winding carriers for wet treatment are already known in the axial direction (DE-PS 881 490), the winding surface of which consists of a flat metal strip which is helically wound around the axis of the winding carrier and has a wavy configuration.
  • Such winding carriers are always more or less unstable due to their structure and therefore fear difficulties, especially when winding at high speeds. Even when they are compressed in the axial direction, radial displacements of the individual gears can occur relative to one another, which complicate the use of such a winding carrier.
  • a bobbin of the type mentioned is known (DE-PS 1 635 084), which has generally proven itself in the wet treatment of threads and yarns.
  • this winding carrier ring elements are provided parallel to one another between end rings arranged on the end face, between which essentially axially extending connecting webs are arranged.
  • the connecting webs together with the ring elements form the winding surface on which the inner layers of a thread or yarn package come to rest.
  • the inner windings of such coils therefore rest on the ring elements and on the outer edges of the connecting elements extending into the winding surface.
  • the individual ring elements are to be regarded as rigid.
  • the object of the present invention is now to provide a winding carrier of the type mentioned at the outset, which avoids the disadvantages of the relevant known winding carriers and in particular excludes jamming of the inner layers of a winding with high certainty.
  • each ring element has at least two axially protruding bulges distributed over its circumference, each of which engages in corresponding bulges of at least one adjacent ring element, and that the connecting webs flexibly connect adjacent ring elements in the area of the cooperating bulges, thereby inclined to the axial direction of the winding carrier and are radially offset with their outer edges in relation to the winding surface.
  • the winding surface is formed only by essentially rigid ring elements, not by connecting webs which inevitably have to deform strongly when the winding carrier is pressed together.
  • the connecting webs are not shortened by folding or otherwise in the axial direction, but only perform a bending movement. This eliminates a major reason for the jamming of inner layers of yarn.
  • the interlocking of the bulges of adjacent ring elements in this area always leads to a more or less strongly curved course of the free space in the area of the bulges, so that the inner layers of yarn between the ring elements are prevented from entering here.
  • the arrangement of the derbinding webs between the ring elements in the region of the bulges further ensures that the ring elements in the region of the bulges cannot be pressed directly against one another.
  • the bulges of a ring element can directly adjoin one another in the circumferential direction.
  • each ring element also leads to the fact that the ring elements are not completely rigid in a very desirable manner.
  • the ring elements can therefore give way to a certain residual shrinkage of the winding located on the winding support. Such a radial compression is, however, only possible to a relatively small extent.
  • the winding support according to the invention can also be designed so that the ring elements at the transitions to the bulges and / or in the bulges themselves have bending points with a reduced cross section. This makes it even easier to absorb residual shrinkage.
  • the winding support according to the invention can also be designed so that the bulges of the ring elements in are substantially V-shaped.
  • the inclination of the legs of the bulges can take into account the course of the inner yarn turns in order to ensure the greatest possible crossing angle between the legs of the bulges and the inner yarn turns, so that the penetration of the inner yarn turns into the free space in the area of the bulges can be excluded.
  • the winding support according to the invention can also be designed so that the individual bulges are stepped or corrugated. In this way, too, the rigidity or the flexibility can be influenced.
  • the winding support according to the invention can also be designed so that the connecting webs are inclined by more than 30 ° with respect to the axial direction of the winding support.
  • the entire winding support is pressed together not by axially shortening the connecting webs, but rather by bending these connecting webs.
  • the winding support according to the invention can also be designed such that the bulges of adjacent ring elements are flexibly coupled to one another by at least two connecting webs.
  • the winding carrier according to the invention can also be designed such that it has at least one end ring which forms bulges which engage in corresponding bulges of the adjacent ring element or accommodate these bulges.
  • Each end ring can be adapted to the respective requirements in terms of its width, surface quality and outer diameter.
  • the winding support according to the invention can also be designed so that at least one end ring forms a receptacle for a thread reserve.
  • the winding support according to the invention can be designed in such a way that it has at least one intermediate ring, which forms bulges on both sides, which engage in corresponding bulges of the adjacent ring elements or accommodate these bulges.
  • the degree of radial stability can be determined in the desired manner.
  • ring 1 and 2 has an upper end ring 1 and a lower end ring 2. Between these end rings 1, 2 there are ring elements 3 which run parallel to one another and parallel to the two end rings 1, 2. In the exemplary embodiment shown, the ring elements 3 are identical to one another. Their outer diameter corresponds to that of the end rings 1,2.
  • Each ring element is provided with a plurality of bulges 4, only one of which is shown in FIG. 1 to simplify the illustration.
  • These bulges 4 are essentially V-shaped and are all directed in the same direction.
  • the bulges 4 of the ring elements 3 are aligned one behind the other, so that the bulge of one ring element 3 can engage in the bulge of a ring element 3 adjacent in the axial direction.
  • Corresponding bulges 5 are attached to the end ring 1.
  • the end ring 2 has corresponding bulges 6, in which the bulges 4 of the adjacent ring element 3 can engage.
  • the end ring 2 is suitable for receiving a thread reserve.
  • the individual ring elements 3 are flexibly coupled to one another by connecting webs 7 which lie in the region of the bulges 4.
  • a connecting web 7 engages on one side, which cooperates with a leg of the axially adjacent bulge.
  • the connecting webs 7 run inclined with respect to the axial direction of the winding support. This inclination is preferably about 30 °. Its outer edge is offset radially inwards with respect to the winding surface. They are dimensioned such that they bend correspondingly when the winding carrier is axially pressed together and thus when adjacent bulges 4 engage one another.
  • the bulges 5, 6 of the end rings 1, 2 are connected to the adjacent ring elements 3 via connecting webs 7, as are the ring elements 3 with one another.
  • each ring element 3 is provided with six bulges 4 over its circumference.
  • the number of these bulges can vary according to the respective requirements.
  • This embodiment has an intermediate ring 10.
  • the part of this winding carrier between the lower end ring 2 and the intermediate ring 10 corresponds in its construction to the winding carrier according to FIG. 1.
  • the intermediate ring 10 has bulges 4 on its two sides which project axially in opposite directions. This means that the bulges 4 of the ring elements 3 below the intermediate ring 10 in FIG. 3 point downwards and above the intermediate ring 10 upwards.
  • the structure of the winding carrier is symmetrical with respect to a plane running through the intermediate ring 10. Consequently, in the exemplary embodiment the upper end ring 11 is configured in the same way as the lower end ring 2.
  • 5-7 is also symmetrical with respect to a plane running through an intermediate ring 13.
  • the bulges 4 provided on the end rings 1, 12 project axially on both sides of the intermediate ring 13 in the direction of this intermediate ring.
  • the intermediate ring 13 has a certain axial extent and has bulges 14, in which the bulges 4 of the ring elements 3 adjacent to the intermediate ring 13 can engage.
  • FIG. 7 shows the winding support according to FIG. 5 in the axially compressed state. Only the lower part of the winding support is shown in detail.
  • the 8-10 has ring elements 3, in which bulges 4 directly adjoin one another.
  • the bulge 4 of a ring element engages in a corresponding bulge 4 of an adjacent ring element 3.
  • Two bulges 4 of this type are flexibly coupled to one another by a total of four connecting webs 7, two of which each lie on one side of the bulge 4 and run essentially parallel to one another.
  • the connecting webs 7 are offset radially inwards with respect to the winding surface.
  • Plastic is particularly, if not exclusively, suitable for the production of this winding carrier.
  • the winding support can be designed so that its resistance to axial and / or radial compression varies over the height of the winding support.
