The two deliveries realize mechanical transmission, and the electrical control runs completely independently so that one machine can achieve two controls and two purposes. The machine compares favorably with the products of international and domestic famous enterprises and is at the leading level. Its sliver output speed is up to 1000m/min.
Equipped with two sets of Uster USG3 auto leveler systems, it has the performance and characteristics of automatic control, intelligent detection, remote maintenance, and efficient operation, the quality of output sliver is stable and reliable.
The resultant yarn quality of the spinning machinery can be effectively improved, and the CV% value of evenness is improved by 0.6 ~ 1%. As to the weight unevenness of ripe slivers:
For 1m ripe sliver, the weight unevenness CV1m is < 0.4;
For 3m ripe sliver, the weight unevenness CV3m is < 0.3;
For a 5m ripe sliver, the weight unevenness CV5m is < 0.2.
