Abstract (en)
A first yarn end untwisting pipe (40A) includes a hollow pipe main body (41) that extends in an axial direction (D1). An injection hole (43) is formed in a peripheral wall (42) of the pipe main body (41). A first opening part (45), which is an inlet of the injection hole (43), is formed on an outer surface of the peripheral wall (42), and a second opening part (46), which is an outlet of the injection hole (43), is formed on an inner surface of the peripheral wall (42). The second opening part (46) is positioned closer to a second end (41b) than the first opening part (45). The first opening part (45) is an elongated hole that extends in a width direction (D3) that is orthogonal to the axial direction (D1).
