Abstract (en)

A stripping roller (19) for drawing fibres (11A) from a tops or feeding sliver (11) for open-end spinners, in which the teeth, which are circumferentially out-of-alignment, are formed on the outer periphery of laminar flexible rings (50) mounted uniformly spaced apart by spacers which have constant thickness and which are deformed with respect to the planar shape, i.e. "twisted" by means of two annular end elements provided with facing complementary shaped surfaces, the rings having inclined drawing teeth, i.e. hooking teeth which are alternated with discharging teeth having opposite inclined profile.
