Definitions

  • a textile treatment sleeve has a shell, which may be cylindrical or conical.
  • the shell has uniformly distributed elements yielding in two diagonal directions and is thereby capable of shortening axially and radially.
  • the shell also has rigid diagonal webs connecting the uniformly distributed yielding elements.
  • the invention relates to a sleeve of thermoplastic material with a cylindrical or conical shell, for the heat and/or wet treatment of threads and yarnsv
  • threads and yarns are often wound on textile sleeves and subjected to the heat and/or wet treatment in this state.
  • the heat treatment may be a shrinking treatment and the wet treatment may be dyeing of the threads and yarns.
  • lt is known to provide, for shrinking of threads and yarns, a sleeve of thermoplastic synthetic material, known as a shrinking sleeve, which can be compressed, at the required shrinking temperature, in radial direction under the action of the material to be shn'nked and which remains in the compressed state after shrinking due to plastic deformation.
  • the shell of the sleeve is formed with longitudinal slots uniformly distributed around its circumference, these slots subdividing the shell of the sleeve into a number of shell elements. Further, in this shrinking sleeve, the shell elements are interconnected with the aid of connecting members which form hinge points which, due to the shrinkage of the material by heat, permit the shell elements to move with reference to one another and in the direction of the axis of the sleeve.
  • thermoplastic synthetic material for the purpose of dyeing threads and yarns
  • dyeing sleeve which, for the purpose of reducing its volume and the volume of the threads and yarns wound on it, can be compressed in the axial direction and which, when dyeing under the application of heat, remains substantially in the axially compressed state after completion of dyeing.
  • the known dyeing sleeve comprises a sleeve shell composed of rigid coaxial rings disposed at uniform axial distances apart and of webs interconnecting the rings and being elastically and/or plastically deflectable in axial direction.
  • the webs interconnecting the rings have at least one portion inclined with reference to the longitudinal direction of the sleeve shell and are uniformly distributed around the sleeve shell. Further, preferably the webs are V-shaped and the limps of the V point in the same direction. Therein, moreover, the webs disposed between two rings are provided at their apex zones with an inner stabilizing ring.
  • the invention has the object of providing a textile sleeve of thermoplastic material having a cylindrical or conical shell, for heat and/or wet treatment of threads and yarns, wherein the sleeve undergoes with axial compression simultaneously a positive reduction in diameter, and with radial compression simultaneously a positive reduction of its axial dimension.
  • this object is realized by a sleeve of the kind hereinbefore mentioned, wherein the shell of the sleeve comprises uniformly distributed elements which are elastically and plastically yielding in both diagonal directions and are thereby capable of shortening and rigid diagonal webs connecting the yielding elements.
  • the sleeve is made of a thermoplastic material, such as polypropylene for example, the yielding elements will be elastically deformable at room temperature, and both elastically and plastically deformable at higher temperature.
  • the yielding elements and the connecting diagonal webs may be integral.
  • This construction of the sleeve is particularly suitable for manufacture from plastics.
  • the yielding elements of the sleeve are arranged in longitudinal and transverse rows. This configuration offers advantages from the point of view of uniform yieldingness of the sleeve, and is also advantageous for winding on the unreeling of threads and yarns.
  • the yielding elements may have an annular configuration with the diagonal webs connected to their periphery. Accordingly, the yielding elements may have a circular, oval, square, rectangular or polygonal form.
  • the annular configuration of the yielding elements is particularly suitable to produce their yieldingness. Apart from that, this construction of the yielding elements permits simple connection of the diagonal webs.
  • the yielding elements may have an angular configuration, for example with rounded-off comers, with kinking and bending points, serving to improve their yieldingness, wherein the diagonal webs are connected to these kinking and bending points. This configuration produces the deformation of the yielding elements by kinking and bending thereof at certain points.
  • ends of the sleeve shell may be provided with end rings and the diagonal webs at the ends of the sleeve shell may be integral with the end rings.
  • the end rings are of advantage for axial compression of the sleeve and for winding up and unreeling of threads and yarns.
