Abstract
Flat cleaning system for a card equipped with a set of revolving flats, in which the flats (12) consist of a T-shaped profile, and in which, by temporary sealing, of the room between the webs 18, 18a of two neighboring flats (12,12a) using a sealing element 30, a longitudinal duct is formed, in which duct an air stream is generated. By this air stream, any fly waste accumulated on the back side of, and between the flats 12, 12a is eliminated. The air stream in the duct, generated by lateral suction, cleans any fly waste and dust particles accumulated in the duct out of the duct, only low energy suction being required.
