Abstract:
The front top roller (20) includes a fiber contacting portion (30) and a reduced-diameter portion (31). The fiber contacting portion (30) has a substantially uniform outer diameter. The reduced-diameter portion (31) is provided at both ends of the fiber contacting portion (30) in an axial direction, and is formed with an outer diameter smaller than an outer diameter of the fiber contacting portion (30). The fiber contacting portion (30) has a width (W1) in an axial direction of 18 mm and the outer diameter (D1) of 30 mm. An outer diameter (D2) of the reduced-diameter portion (31) is 25 mm.
