Definitions

  • the present invention relates to an art of a yarn winding device.
  • a yarn winding device is well known as a device which rewinds a package while eliminating threading defects of a yarn feeding bobbin around which is wound a yarn that is spun by a fine spinning machine.
  • the yarn winding device provided therein with a yarn accumulating device (accumulator) is known (for example, see the Patent Document 1).
  • the yarn winding device provided therein with the yarn accumulating device can continue yarn winding work without stopping a package winding device.
  • the package winding device winds a yarn accumulated in the yarn accumulating device and continues the yarn winding work.
  • a yarn accumulated in the yarn accumulating device is led out (a yarn end is pulled out) and introduced into a yarn splicing device, and the introduced yarn end is yarn together with a yarn end at the side of the yarn feeding bobbin.
  • the yarn accumulating device when sloughing (loop cast-off) occurs in a yarn wound out from the yarn accumulating device toward a package, yarn breakage occurs and the winding of the package is stopped.
  • the conventional yarn accumulating device represented by the Patent Document 1 since a yarn wound former is pushed upward by a yarn wound later, fluffs may be intertwined with each other, thereby causing sloughing at the time of unwinding of the yarn. Since the yarn wound former is pushed upward by the yarn wound later, at the time of pulling out the yarn end accumulated in the yarn accumulating device, the fluffs may be intertwined with each other, thereby causing draw-out defect.
