ABSTRACT:
When a weft yarn is broken between a fixed drum type weft yarn measuring and storing device and a picking nozzle, the weft yarn extending to a winding yarn guide is reliably delivered to a yarn suction device by the steps of generating an air current inside the winding yarn guide in the picking direction, generating an air current inside the yarn suction device in the drawing direction while the winding yarn guide is aligned with the yarn suction device disposed in front of the weft yarn measuring and storing device, and keeping a retaining pin from being advanced toward the drum. Thereafter the broken weft yarn on the drum is discharged by retracting the retaining pin.
