This machine adopts four roller feeding,double cylinder double doffer structure, adapts polyester fiber, polypropylene and other chemical fibers and also adapt to some natural fiber carding.Cast iron frame round wall board, structural stability; Sheet metal cover Shell laser cutting CNC bending, beautiful appearance; Shell cylinder lifting, convenient and safe; All roller dynamic balance processing, runout control within 3 wire, stable and reliable operation;with suction fan, base 600mm high, convenient daily maintenance Overhaul. All motors are individually variable frequency controlled and equipped with metal detectors. The work roll is controlled by a separate motor, and the speed of the work roll is adjusted according to the difference between the cylinder and the raw material, so that the chemical fiber is optimally combed.
