The cleaning or blow room line comprises at least one bale opening machine connected by ducts and at least one cleaning machine and a blender with a plurality of cards. The transport of the fiber flocks extracted by the at least one bale opening machine through the cleaning line is achieved by suction ventilators provided for such cleaning line. After at least one cleaning location a pressure sensor is arranged in an associated duct and delivers a signal to a control or regulator which controls or regulates, as the case may be, the size of a false air opening which co-dictates the air flow through the ducts. The false air opening can be constructed as an adjustable element in the form of a hinged flap or a slide element positioned relative to an opening in a duct, whereby the regulator controls the extent to which the flap or slide member is pivoted or slid, thereby adjusting the amount of air that is drawn into the duct.

Cleaning line with false air infeed valve for regulating air flow therein

The cleaning apparatus has an air main mounted on a movable frame which can be brought against the side of a card. The air main includes a plurality of suction orifices which can be brought into registry with deformable air outlets at the side of the card which communicate via air lines with extraction stations of the card.

Apparatus for cleaning a card

A revolving flat arrangement for a carding machine is characterized in that a suction tube with a suction opening is arranged within the loop at the deflection position from the card cylinder to the cleaning device and/or at the deflection position before the card cylinder. Fibers and particles of contamination which are carried by the flats and which reach the interior of the loop are sucked out through the suction tube.
