• The fiber opening machine is mainly used for opening conjugate hollow siliconized polyester fiberthat short than 100mm length.• Automatic raw material feeding conveyer function is to send the material into the opening rollersautomatically, so that assures the operators safety.• There is a track device under the conveyer and fixed into the roller edge, so that the conveyer canbe running in a straight way without deviation damage.• The developed rollers are assembled with metallic V-wire that the fiber can be opened for more than98% to 100% and not be damaged.• High opening capacity that can be 200kg to 450kg per hour according to different machine modeland the material• Roller balance processing• Overload protection• Long life operation and lower repairing rate• It can be handled by only one operator with simple operation.
