Compact kit and compact siro-spinning are of four-roller device designed for modification on existing traditional ring frames.

1.Four-roller system and apron lattices are of positive drive.

2.Negative pressure system adopt main blower with general air duct and filter net to avoid dirtying workshop.

3.Modular design, 6 spindles or 4 spindles in one unit.

4.Well-designed negative pressure distribution ensures consistency of airflow at each suction nozzle.

5.The suction nozzle of suction pipe is of optimization design for integrating the strand of fiber easily.

6.Inverter is available for controlling the negative pressure of compact spinning for different yarn count.

7.Smoothly moving of the yarn is guaranteed by tensin device of the apron lattice.

8.Installation of flute pipe is reasonable, parts concerned can be cleaned dynamically.
