Abstract
A fluffing suppressing device for a winder for winding spun yarns capable of suppressing fluffing to a degree that may not cause troubles attributable to fluffs when the spun yarns are used as warp yarns on an air jet loom or the like. The present invention provides a fluffing suppressing device to be placed in a yarn path on the winder comprising a nozzle having an air injection holes for injecting air into a yarn passage in direction tangent to the yarn passage.
Claims16
A fluffing suppressing apparatus for use with an automatic winder for winding spun yarns, the automatic winder defining a yarn winding path, the fluffing suppressing apparatus comprising:
- an air nozzle disposed substantially in the yarn winding path for imparting air currents to the spun yarn as the spun yarn is wound by the automatic winder,
- a yarn guide pipe extending longitudinally through the air nozzle, the yarn guide pipe defining a yarn running path having a first end and a second end, a first opening at the first end of the yarn running path, and a second opening at the second end of the yarn running path,
- at least one air injection hole formed in the yarn guide pipe for injecting air supplied to the air nozzle into the yarn guide pipe in a direction tangent to the yarn guide pipe and at a predetermined angle with respect to the yarn running path,
- a nozzle cap defining a portion which partially covers the second opening of the yarn guide pipe, and
- a control plate disposed adjacent the air nozzle such that the nozzle cap is substantially between the control plate and the air nozzle,
- wherein the control plate controls the position of the yarn in cooperation with the nozzle cap.
An automatic winder for winding yarn, the automatic winder defining a yarn winding path, the automatic winder comprising:
- winding means for winding yarn from a supply bobbin;
- and
- fluff suppressing means for reducing an amount of fluff in the yarn, the fluff suppressing means including
- an air nozzle disposed substantially in the yarn winding path for imparting air currents to the yarn as the yarn is wound by the automatic winder,
- a yarn guide pipe extending longitudinally through the air nozzle, and
- at least one air injection hole formed in the yarn guide pipe for injecting air supplied to the air nozzle into the yarn guide pipe in a direction tangent to the yarn guide pipe and at a predetermined angle with respect to a yarn running path through the yarn guide pipe.
