Definitions

  • the invention relates to a yarn carrier for multiple use for threads, consisting of an essentially cylindrical base body with a wall thickness of at least 4 mm, free of internal fittings, made of hard paper, wood or plastic, with a replaceable cover.
  • Yarn carriers are mass products and mostly consist of spiral-wound cardboard or plastic. They have proven themselves as disposable cores for high winding speeds (man-made fibers / textile industry, June 1976, pages 522-525).
  • Reusable thread carriers so-called head tubes, have internal structures, are not completely balanced, and are therefore unsuitable for higher speeds.
  • a disposable sleeve which is made of paper and is provided with a plastic coating flanged on its outer edge.
  • Such sleeves are completely unsuitable for stacking on top of one another and for reuse.
  • Multiple use with sleeves of this type has proven to be uneconomical, since the known sleeves are damaged or deformed, especially on their end faces and surfaces.
  • Yarn carrier sleeves must have a certain stability so that they are not deformed or compressed by the yarn to be wound on them.
  • Such a sleeve is not reusable. Sorting is usually done by hand and cannot be limited to visible defects only; hidden defects must also be recorded in order to avoid run-out problems and flow problems of the yarn in the case of a reusable sleeve.
  • the known yarn tubes have to have a defined surface which is as homogeneous as possible and are therefore relatively complex to manufacture and control.
  • the object of the invention is to provide a yarn carrier which can be used multiple times and does not have the disadvantages of the known yarn carriers.
  • end of the yarn outlet on the yarn outlet side consists of an outer wall and an inner wall, the cover being flanged flush over the outer edge of the outer wall of the base body and both end faces of the yarn carrier having the same inner diameter.
  • a major advantage of the same inner diameter is that one or more of the yarn carriers according to the invention can be quickly and directly pushed onto the mandrel of a winding machine.
  • the base body preferably consists of hard paper or wood, the surface of which is not critical, that is to say does not need to be defined. Such sleeves can therefore be manufactured economically with little effort.
  • the base body can also consist of any plastic, which, however, must not deform during use, so that its reusability is guaranteed.
  • the wall thickness of the sleeve should be at least 4 mm, preferably 6 mm, which is a multiple of the thickness of a coating. However, it is largely dependent on the stability requirements for the base body, which in turn is determined by the yarn to be wound up.
  • a circular channel is expediently provided in the base body. It is used to retract a plastic cover. This creates a cavity in the interior of the yarn carrier sleeve without any internals. Depending on its length, this allows a number of yarn carriers arranged one behind the other to be attached to a mandrel.
  • the outer edge of the trough is advantageously lower than the inner one and ensures that a yarn runs smoothly.
  • the protruding inner edge is a protection when stacking and transporting a full spool. The coil weight rests on this edge.
  • the outer surface of the base body is flush with an exchangeable plastic cover which is flanged over the outer edge of the end surface on the yarn outlet side.
  • Interchangeable means that the plastic cover can be easily replaced if damaged, which is done by cutting and peeling off the old cover and fitting a new one. The replacement is conveniently done automatically.
  • the cover can be made of any plastic or paper on which the wound yarn leaves no groove marks and which is largely insensitive to impact. Its surface can be either smooth or rough or, for example, orange peel-like in accordance with the yarn to be processed. A smooth surface, especially over the front edge, allows the yarn to be pulled off without damage, for example in weaving, texturing and warp-making. The retraction and fastening in the 360-degree channel ensures that the plastic cover is securely anchored completely.
  • the base body can also be provided with a head part which carries a support ring.
  • the gutter with the outer lower and inner higher wall is provided in the head part.
  • the support ring connected to the head part has the advantage that yarn names can be attached to it, which would otherwise have to be attached at an inappropriate point. Attaching the designation directly to a plastic cover is particularly inappropriate for reusable use. Another advantage is the fact that the ring can be used to easily pull a full spool off the mandrel and transport it without damage.
  • an annular head part 2 is provided in the interior of the base body 1, which sits on the end face of the base body 1 and is fastened to the cylinder wall of the base body 1 by a clamp fit.
  • the head part 2 consists of an upper cylinder part 6 and a lower cylinder part 7 and a support ring 8 provided at the height of the end face.
  • the head part 2 is preferably made from a single plastic part.
  • the support ring 8 is provided for receiving a titer rondelle shown in dashed lines.
  • Fig. 5 the thread run-side edge 4 is shown enlarged.
  • the wall 5 '' is level 9; the wall 5 'is formed as a convex surface 10.
  • the circular ring surface 9 lies at least 3 mm above the surface 10.
  • the yarn carrier according to the invention is preferably made of hard paper, wood or plastic and is particularly suitable for winding on filament spinning, draw-bobbin, draw-twist, texturing, winding and twisting machines.
