ABSTRACT:
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.
