Abstract (en)

Yarns are automatically threaded onto yarn guides. A yarn threading unit 33 of an automatic yarn threading device includes a suction gun 42, a pressing roller 46, and a yarn separation guide 47. The suction gun 42 sucks and retains yarns having been spun out. The pressing roller 46 is pressed onto the yarns retained by the suction gun 42 so as to widen the intervals of the yarns. The yarn separation guide 47 is provided with grooves 47a lined up in one direction. After the grooves 47a of the yarn separation guide 47 are moved to a position opposing yarns with the intervals widened by the pressing roller 46, the yarns are inserted into the respective grooves 47a by retreating the pressing roller 46 to a position not making contact with the yarns. Thereafter, as the yarn separation guide 47 is moved toward the base end side in the first direction, the yarns are threaded onto fulcrum guides.
