Worldly prevail drafting system of 4-roller with double short aprons is adopted. Between the first and the second roller is collection zone without drafting, which is good for the production of roving with superior quality.
In the whole course of roving, the control system of real-time measure and feedback, which is composed of many high-accuracy rotary encoders
and computer, controls the roving tension strictly according to the mathematics model. The unique control system that can restrain yarn faults effectively at the start and the stop of the machine, guarantees the stability of roving quality. Travelling blower & suction system suck the waste from the top cleaner automatically, working with high-efficient suction device at back of the machine, clean the waste on the top rail cover and the roller beam, as well as the waste scraped off from the bottom cleaner circularly, and reduce yarn defects effectively.
Applying the patent technology of power cut-off avoids the breakages or yarn faults happening on whole machine when accident disconnection fault caused on outer electricity network

High speed
Adopt fully enclosed high-speed flyer. The maximum mechanical speed can reach 1600rmp. Controlled by microcomputer, the rotational speed of flyer can be changed automatically in the case of big package, so can reduce the breakage of roving and improve production efficiency. The fully-enclosed main drive box lubricated with oil bath has the features of high speed and low noise.
Convenient maintenance
Perfect electric control system has features of reasonable arrangement and structure, strong anti-interference ability, high reliability, and convenient maintenance. The structure of driving is simple, saving time of maintenance. It could communicate with all kinds of PC through network at high speed, so as to achieve the network production management and remote malfunction analysis.
