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.
Claims27
A fiber cleaning device 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 comprising:
- a separating knife with a knife edge for being located 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,
- wherein 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.
A carding machine, comprising:
- a rotating clothing cylinder;
- a housing surrounding the cylinder;
- an opening in the housing for removing impurities;
- a fiber cleaning device having
- a separating knife with a knife edge located 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;
- and
- a traveling flat having a flat bar, the flat bar having a pressure increasing element that increases a pressure upstream, in the rotational direction of cylinder, of the opening,
- wherein the pressure regulating element adjusts a pressure between the housing and the cylinder such that fiber material accumulation on the knife edge is promoted.
