Abstract
A weft yarn extracting device for extracting a weft yarn faultily inserted in a cloth fell includes an extracting unit including a pair of fingers, a first shifting unit for shifting the extracting unit between a standby position and an operating position, and a second shifting unit for turning the extracting unit about an axis. In operation, one end of the weft yarn is sucked in the extracting unit by the agency of an air current and is gripped by gripping members. Then, the gripping members are rotated to extract the weft yarn by winding the weft yarn around the gripping members, while the extracting unit is turned about an axis by the second shifting unit to separate the weft yarn from the cloth fell.
