Abstract (en)

The clearer roller for a stripping roller (46) has bristles (50) mounted in several segments that are bolted to a shaft to form a sleeve (59). Preferably two segments are used to give a carrier 90 to 150 mm diameter. An Independent claim is also included for the use of a rotating brush as a clearer for the stripping roller (46) on a card in a position after the fiber web (63) has been removed. The brush rotates at less than 2000 r.p.m. to generate an airflow to lift residues into a suction hood. Alternatively the bristles can penetrate the wire (64) to remove residues directly.
