< p > JWF1211 carding machine has achieved technological innovation in three aspects: enlarging carding area design, precise feeding control technology and new self levelling control technology. The carding area is increased by 17% compared with the JWF1203 carding machine. The digital information processing (DSP) control method is adopted, the data calculation is fast and accurate, and the accuracy of the leveling is high. The new three in one self levelling control system, which is tested by the lower cotton box pressure, the feeding thickness of the cotton cake and the thickness of the cotton strip, is detected at three points, so that the cotton layer is evenly and precisely controlled when forming, effectively improving the unevenness of the sliver.

< p > SMARO-NEW automatic winding machine adopts winding tension control technology combined with closed loop control and automatic speed control system, variable speed anti stacking technology, proportional pressure regulating auxiliary anti folding technology, advanced electronic control technology and special sensor, new type of air traffic control structure and new type guide yarn mechanism.

The above products have been authorized by many a href= "http://www.91se91.com/news/index_f.asp" > inventions patent < /a > and utility model patents and accepted patent for invention.
