Definitions

  • the invention relates to a hollow spindle, in particular for the production of elastic Wrapped yarns with a thread channel running coaxially to the spindle axis which a yarn, in particular an elastic core yarn is moved axially through.
  • the invention is therefore based on the object of a hollow spindle, in particular for Manufacture of elastic wound yarns, in which to create the friction between the inner surface of the thread channel and the core yarn are reduced to a minimum is and thus a trouble-free processing of the yarn is guaranteed.
  • the ribs By the number of point contact points between the ribs and through To reduce the thread channel passed through, the ribs should be appropriate be arranged at larger axial distances from each other.
  • An advantageous embodiment of the hollow spindle is that the thread channel formed by a tube inserted into a central bore of the hollow spindle which has the ribs on its inner surface.
  • Ribbed tube can namely be produced relatively inexpensively and you can also see the inside surface of the tube, i.e. H. the inside Optimize the projecting ribs in order to achieve the adhesive effect mentioned at the beginning reduce.
  • the inner surface of the tube should be fine. Under thread-like is understood to mean a surface that does not roughen the thread.
  • the surface should not be smooth because this creates an adhesive effect, it should be matt or similar to a very fine orange peel. Such Surface can be pulled when pulling the tube or its deformation Generation of the ribs is achieved.
  • a hollow spindle is more common for the production of elastic winding yarns Design shown.
  • the hollow spindle 1 is rotatably mounted on the spindle bench 2 and is by means of a drive belt 3, which simultaneously has a larger number of spindles drives, rotated.
  • a supply spool 4 is attached to the spindle 1, which carries the winding thread 5.
  • the core yarn is from another, not shown supply spool unrolled and under tension from bottom to top through the Hollow spindle 1 pulled through.
  • this has a coaxial to the spindle axis A.
  • Thread channel 9 which expediently through a in a central bore 7 Hollow spindle 1 inserted tube 8 is formed.
  • this tube 8 is shown in FIGS. 2 or 3 recognizable.
  • the tube 8 is with several circumferential, inward over the inner surface of the tube projecting ribs 10 provided. These ribs 10 are at larger axial distances a arranged from each other. With an inner diameter d of the tube 8 of for example, 6 mm, the ribs 10 at axial distances a of about 20 mm be arranged from each other. Here, the ribs 10 are at an amount c of approximately 0.5 mm inwards over the inner surface 8 a. The amount c and the distances a must be coordinated so that the core yarn 6 only on the ribs 10th rests point-like, but otherwise at a distance from the inner surface 8 a is held.
  • the ribs 10 a, 10 b arranged helically in the form of a double helix, namely the helix 10 a and the coil 10 b.
  • dimensions a and c those made for FIG. 2 apply Similar explanations.
  • the ribs 10, 10 a, 10 b are expedient by plastic deformation of the Tube wall formed. This is done so that the ribs go through in the circumferential direction ( Figure 2) or helical ( Figure 3) groove-like indentations 12, 12 a, 12 b of the outer surface of the tube are formed. This groove-like Impressions 12, 12 a, 12 b of the tube wall then form those on the inner one Surface protruding ribs 10, 10 a, 10 b.
  • the tube 8 suitably consists of metal, namely advantageously brass or stainless steel. More information about the surface design of the inner surface of the tube have already been made above.
  • the inwardly projecting ribs 10, 10 a, 10 b initially have the advantage that Core yarn 6 always only has point contact with the ribs 10, 10 a, 10 b, otherwise it is kept at a distance from the inner wall 8 a of the tube. As a result, the friction between the core yarn 6 and the thread channel 9 can be entirely be significantly reduced. It is also believed that as a result of the Design of the ribs 10, 10 a, 10 b and by the relative movement of the Core yarn 6 opposite the ribs near the inner surface 8 a an air cushion builds up, which holds the core yarn in the center of the tube 8 and thereby Prevents contact or at least reduces friction.
  • the use of the described tubes increases the cost of manufacturing the Hollow spindle not. It can namely the deep hole 7 with greater feed be produced when drilling the spindle 1, because on the surface of the Deep hole no consideration must be taken. Through the thereby achieved The cost of manufacturing and assembling the tube will save time made up for.
