  • the winding control section 60 includes a turret control section configured to control rotation of the turret motor 27.
  • An operator operates the keyboard 13 or the like to actuate the take-up winder 7.

  • Figure 8 is a diagram showing an evaluation indicator for the tests for verifying the technical effects of special setting for the winding angle.
  • Figure 8A shows the appearance of a taper end packaged according to the embodiment.
  • Figure 8B shows the appearance of a taper end package in a comparative example. That is, the end surface shape of a full package is observed, and an end surface shape having a linear, beautiful silhouette as shown in Figure 8A is determined to be "o (good)".
  • an end surface shape obviously including protrusions and recesses as shown in Figure 8B is determined to be "x (bad)". If it is impossible to determine whether the end surface shape is "o" or "x”, the end surface shape is determined to be " ⁇ ".
  • Table 1 shows that a winding angle of at most one degree allows the end surface shape to be properly finished. Furthermore, the finish of the end surface shape which can be obtained at a winding angle of at most one degree failed to be achieved at a winding angle of at least 1. 2 degrees.
  • the taper end package is adopted because when the monofilaments are cross-wound into a package, the end surface of the resultant package is easily collapsed.

In contrast, a winding angle ⁇ [deg.] of 0. 5 makes the winding density [%] extremely higher at the longitudinal end of the package than at the longitudinal center thereof.
  • the yarn properly follows the motion of the yarn guide before the reversal of the yarn but has difficulty following the motion of the yarn guide particularly after the reversal of the yarn. This is indicated by the different calculation data shown by the solid and dashed lines on the graph in Figure 9B .
  • the yarn winding apparatus 1 is configured as follows.
