The buildup of loose fibers, dust, and lint that forms a curved, fuzzy ridge on the top clearers or drafting rollers of a spinning machine. If left unchecked, this waste can break off and get spun into the yarn, causing slubs and weak spots. Operators must regularly clear the rollers to prevent it.
