A454H series roving machine suitable for a carded, combed-cotton fiber,as well as 65 mm of artificial fibres, pure or blended, and later cookedinto different numbers and different twist of roving, for spinningspinning spinning spinning machine.

A454H include A454EH, and A454GH are two series roving machine models.A454EH spinning 51 millimeters of cotton and cotton blends, consisting mainly of A454GH spinning 65 mm long fiber. A454H series is based on theA454 upgrading through inverter models. The machine structure isadvanced, speed, startup slow slow start can be achieved, improve theevenness of quality and improvement of roving tension, power-savingextended motor life, easy to monitor and low failure rate, easy toinstall, reliable operation, thereby reducing lathe operator labor intensity.
