Title:
巻取り機の糸巻返し部で糸欠陥を除去するための方法
Document Type and Number:
Japanese Patent JP4436938
Kind Code:
B2
Abstract:
A method for removing both long and short yarn defects at the winding heads of a bobbin winding machine. Following the appearance of a yarn defect, the length of the defective yarn between the time of the appearance of the defect and the time of a subsequent yarn cut is determined. A suction tube is positioned in front of the winding bobbin to aspirate the defective yarn therefrom. The yarn is unwound, the entry of the yarn into the suction tube is determined by means of a sensor disposed therein, and the yarn length unwound from the winding bobbin and entering the suction tube is determined. The unwinding process is stopped at the time when, on the basis of the detected length of defective yarn, a sufficient yarn length has been aspirated into the suction tube so that, upon subsequent insertion of the yarn from the winding bobbin into the yarn end connecting device, the yarn length wound since the appearance of the yarn defect remains outside of the yarn end connecting device for the purpose of being cut and discarded.
