DEVICE FOR LOCAL DISTRIBUTION OF AIR IN SPINNING FRAME Russian patent published in 1999 - IPC

FIELD: textile industry, spinning. SUBSTANCE: device presents an air duct installed above feed frame of spinning frame. Air duct has longitudinal slots to pass the air and reflecting strips installed in zone of slots by means of plate air dividers to form two air directing channels formed between each reflecting strip and exterior wall of air duct. These channels are oppositely directed in cross-section of air duct to ensure collision of air flows and their coming to production process zone through channels formed between longitudinal edges of neighboring strips. Longitudinal edges of reflecting strips are bent in direction of air flow. Air duct is made without upper channel for air discharge, and air duct external walls have holes. EFFECT: reduced resistance to air flow and more smooth discharge of air from air distributor, decreased air consumption, higher degree of attention and uniform flow of air to production process zone. 2 dwg
