Swiss textile machinery supplier Rieter has recently introduced the new J20 air-jet spinning machine which provides up to 120 spinning units in one machine and two different yarn qualities can be spun at the same time.
Rieter notes that the new spinning unit of the J20 produces higher yarn strength. The improved yarn quality also results in a lower number of quality cuts and reduces natural ends down. Besides, due to the increased spinning stability with fewer quality cuts, it was possible to lengthen the J20 by one section to a total of 120 highly productive spinning positions. Meanwhile, four robots, two on each side, can ensure maximum production efficiency, Rieter says.
The centrally-driven ventilators, the entire electric and electronic systems as well as the supply and disposal connections are integrated in the drive frame. Rieter indicates that separate filter chambers process the waste from the spinning positions and the waste from the robots and are also separate for the left and right machine sides. The waste can be individually collected and further used.
In addition, the bobbin delivery on the drive frame has been lowered to a height of 1.45 meters. This enables the bobbin conveyor belt to be optimally controlled by the operator and the bobbins conveniently removed and placed on pallets. The end section only consists of the service area for the robot at the rear and the free-standing tube feeder with an extended capacity of 350 empty tubes. The two separate tube chains, which allow different color tubes to be fed to the left and right machine sides, are a new feature of the tube feeder. This prevents tubes being mixed up when two yarn qualities are
being simultaneously produced.
