Definitions

  • the invention relates to a textile bobbin according to the preamble of claim 1 and to a device according to the preamble of claim 8.
  • Cross-wound textile bobbins are probably the most common type of bobbin for further processing on fabric making textile machines. Due to the Kreuzbewicklung these coils require no predetermined by their sleeves edge boundary. They can therefore be unwound easily overhead, which ensures high Abspul Oberen.
  • Such cheeses are usually produced as cylindrical or conical cheeses.
  • the end faces of such a coil are either planar, wherein the plane is approximately at right angles to the longitudinal axis of the coil or biconical, that is with bevelled end faces.
  • Biconical coils have relatively stable edges, but have the disadvantage that the chamfered yarn volume is reduced by the bevel with respect to cheeses with vertical edges at the same diameter.
  • the WO 2006/089 691 A1 describes a method of manufacturing a dyeing bobbin having neither vertical nor bevelled straight end edges. Rather, the coil produced by the process is completely rounded. This edge rounding should lead to a uniform flow through the dyeing liquor is ensured throughout the winding.
  • the DE 37 34 445 C2 is for coils with precision winding, in which the crossing angle automatically decreases with increasing coil travel and through the DE 37 40 264 A1 for coils with wild winding known to wind the outer layers with a much larger crossing angle.
  • the EP 1 008 546 A2 refers additionally to the fact that in the cross-angle enlargement also proposed here, due to the increase in the drag length between thread guide and nip line between the winding drum and the coil, the reversal points inevitably shift slightly inwards. In order to achieve a noticeable reduction in the laying width, the crossing angle enlargement must have a considerable extent.
  • the crossing angle enlargement is intended to reduce the risk of knocking off of outer layers in the region of the end faces of the coil.
  • this measure involves a marginal reduction in the amount of thread take-offs, the package density changes considerably in this area, producing unstable thread layers, in particular in the transition region, and producing a noticeable energetic and mechanical load on the thread guide.
  • the reversal points of the winding in the region of the outer layers to the end face of the coil are spaced apart without the crossing angle is increased, in particular remains the same.
  • these reversal points which are particularly sensitive to thread deductions, moved away from the coil position at which the greatest mechanical stress during transport and handling is recorded, without any intervention in the structure of the coil.
  • the fact that it is dispensed with an increase in the crossing angle there are no, in particular no sudden coil density reductions and unstable yarn layers in the shell region of the coil. So effectively the emergence of Garnabange can be prevented on finished cheeses as far as possible.
  • the thickness of the outer layers is not more than 10 mm, preferably 3 to 5 mm.
  • a continuous decrease in the width of the winding in the region of the outer layers avoids in principle Edge angle in the range of 90 ° and is therefore particularly resistant to damage.
  • the reduction of the winding width can also take place in stages, the effect being approximately comparable.
  • the winding width in the region of the outer layers should decrease overall by more than 5% (claim 8).
  • a device according to the invention is described, according to which the traversing device for the thread has a control device for the drive, which is suitable to reduce the Traversierhub according to the predetermined criteria upon reaching a corresponding coil fullness.
  • FIG. 1 is a textile spool according to the invention, a cross-wound bobbin 1 is shown with bobbin tube 2, which has a chamfer 3 in its edge region.
  • bobbin tube 2 which has a chamfer 3 in its edge region.
  • the points of reversal are continuously offset inwards so that the particularly stressed edges on the ends of the coil are tied by the yarn layers lying above them.
  • the volume of the coil is reduced only insignificantly by this chamfer compared to a cross-wound bobbin with completely straight coil edges.
  • the cheese 11 according to FIG. 2 with bobbin tube 12 has a sudden reduction of the winding width. Since the layers with reduced winding width have only a limited thickness, no winding can form in this area, which is comparable due to the right-angled edge susceptible to discounts, as in a cross-wound bobbin with completely flat end faces.
  • cross-wound bobbin 21 with sleeve 22 has a gradation 23 in the region of the outer entangling layers. This gradation is shown particularly clearly again as a detail x. This graduation 23 additionally ensures that in a number of stages a binding of the respective broader underlying layer takes place.
  • FIG. 3 is further shown schematically that the coil is rotated by a peripheral drive by a friction roller 24, wherein the friction roller 24 is driven by a motor 25.
  • a thread-laying arm 26 is provided with a thread guide 27, which is driven by a motor 28.
  • the motor 28 is controlled by a control device 29 in its stroke width so that the respective outer Bewicklungslagen compared to the Hauptbewicklung result in the predetermined shape reduced Bewicklungsbreite.
