AIR DUCTS FROM DISCRETIZATION MECHANISM OF EACH YARN OUTLET OF SPINDLELESS SPINNING EQUIPMENT, FOR EXAMPLE, CORE-SPINNING EQUIPMENT Russian patent published in 1998 - IPC

FIELD: textile industry. SUBSTANCE: air ducts are designed for provision of technologic flow of spinning process in each yarn outlet of spindleless spinning equipment, for instance, core spinning equipment and maintenance of the required level of air cleanness in production room. With yarn-forming chamber in operating position, air ducts in each ducts yarn outlet are in this case, in the form of inner hollows of chamber main members: collector, condenser and guards of turbine and inlet ventilation branch of waste chamber. To ensure direction of air flow, used for additional removal of fibers from card fillet in discretization mechanism, during shutdown of yarn forming chamber, only to waste chamber and improvement in this way of operating properties of spinning equipment, provision is made of additional air duct through which air flow is directed to waste chamber through hole in its bottom to bypass its inlet ventilation branch. Waste chamber has individual mechanical gate for each inlet ventilation branch which automatically closes and opens its inlet window. This window opens with yarn-forming chamber in operating position and closes when it is not in contact with driving belt. Mechanical gate is connected by flexible tie with connecting hook attached to exterior surface of end part of additional air pipeline. EFFECT: higher efficiency. 8 cl, 9 dwg
