Abstract

A fiber cleaning device is provided for use with a carding machine having a rotating clothing cylinder, a housing surrounding the cylinder, and an opening in the housing for removing impurities. The device has a separating knife with a knife edge for locating in the opening and directed counter to a rotational direction of the cylinder, and a pressure regulating element installed downstream, in the rotational direction of the cylinder, of the separating knife. The pressure regulating element is for adjusting a pressure between the housing and the cylinder such that fiber material accumulation on the knife edge is promoted.
