Apparatus for preventing scatter of fly in winder

An apparatus for preventing scatter of fly in a winder having at least one winding unit in which a yarn is unwound from a yarn feeding bobbin and is directed through a tension unit before being taken-up on a take-up package, comprisng a first cover member for covering the yarn feeding bobbin unwound at the winding unit and a second cover member for covering the tension unit, wherein said bobbin includes a yarn layer having a tapered part at the upper portion thereof, and wherein said first cover member substantially covers the tapered part at the upper portion of the yarn layer and further comprising means for moving said first cover member in an elevational direction as the tapered part of the yarn layer is moved during the unwinding of the yarn layer.

An apparatus for preventing scatter of fly in a winder having at least one winding unit in which a yarn is unwound from a yarn feeding bobbin and is directed through a tension unit before being taken-up on a take-up package, comprising:

• a first cover member for covering the yarn feeding bobbin unwound at the winding unit and a second cover member for covering the tension unit, wherein said bobbin includes a yarn layer having a tapered part at the upper portion thereof, and wherein said first cover member comprises a fixed cover body substantially covering the tapered part at the upper portion of the yarn layer, further comprising a balloon breaker fixed integrally to the cover body, a sensor disposed within the cover body for detecting the interface between the feeding bobbin and the yarn layer and generating a signal in response thereto, and a mounting block on which the bobbin may be positioned and fixed, said mounting block being threadably engaged with a threaded rod so as to be movable along the axial direction of the bobbin by the rotation of the threaded rod, and rotation means responsive to said signal for rotating said threaded rod.
