Abstract: A filament positioning control device for composite spinning of filaments and staple fibers comprises a fixed shaft and a hollow shaft mounted thereon. Left and right spiral wheels with left and right spiral grooves are mounted on the hollow shaft. Left and right positioning plates are provided on outer sides of left and right spiral wheels, each having a guide pin engaged in a spiral groove.
