Precise leveling system-FT029

Core of sliver CV

　 FT029 autoleveller is specially used for directive feed mechanism, whose working principle is following: take chute pressure variation to leveling system; control batt status through PID control; detect batt thickness variation by use of precision vertex non-contact sensor to control fiber in short term and detect sliver thickness variation to control fiber in long term, both of them make up of open –close loop control; fit with vector motor to enhance drive precision and ensure sliver CV value.

Long-short term autoleveller
