PURPOSE:Title device that is provided with a specific bulk gas nozzle capable of changing the gas feed paths and the position for jetting gases when yarn break is detected, thus starting various operations for amendment forcedly accompanied with yarn break. CONSTITUTION:Yarn of glass fiber 14 a spun from spinning zone 22 provided with orifice plate 20 is collected by movably shoe 23, passed on means for applying a binder 24 and near nozzle 28 for feeding bulk gas, and wound on winder equipped with collet 26. Device for feeding a bulk gas 78 is composed of pipe for feeding a gas 82, chamber 76, a plurality of gas-jetting pipes 84 connected to nozzles 28 and valves 86 for controlling the jetted gas. When yarn break is detected, the gas from nozzles 28 is stopped, the device is kept away from the yarn path by carriage 34, and a gas is flown from oppositing nozzles 30 to orifice plate 20 to prevent the contamination of the orifice.
