PROBLEM TO BE SOLVED: To provide rubber rollers which can improve the behavior of the fibers winding up along and sticking around the roller surfaces. SOLUTION: The Shore A hardness of the rubber composition to be used for the rubber rollers is adjusted to 68-90 and the tangential loss (tanδ) is set to <=0.12 at 30 deg.C or set to <=0.05 at 50 deg.C.
