Abstract A vacuuming device for carding equipment for cleaning the revolving flats in which a vacuuming box is located between a licker-in and the adjacent flats deflection roller. The vacuuming box is enclosed on all sides. The region of the flats deflection roller on the inside of the revolving flats, accommodates a guide element for diverting dust-laden air in the direction of at least one intake opening in the vacuuming box. This intake opening is associated with the revolving flats. The guide element may be made hollow to receive dust-laden air, and may be connected in a sealing manner with the revolving flats. The vacuuming box may have two intake openings which are placed so that one of these openings always faces an open gap between the revolving flats. The intake openings may be in the form of slots extending throughout the width of the card. A layer for sealing off the revolving flats, may be made of soft material and may be located on the vacuuming box in front of the intake openings.
A vacuuming device with revolving flats for carding equipment for cleaning the revolving flats comprising: a licker-in; a flats deflection roller adjacent to said licker-in; a vacuuming box located between said licker-in and said flats deflection roller and being enclosed on all sides; said vacuuming box having at least two intake openings for dust-laden air, said intake openings being associated with said revolving flats; and a guide element located inside said flats deflection roller for diverting dust-laden air towards one of said intake openings.
