Abstract (en)

[origin: EP3327185A1] A device for a rotor spinning method using multi-level carding includes a spinning system and a computer control system. The spinning system includes a feeding and carding mechanism, a collecting and twisting mechanism, and a winding mechanism. The device is characterized in that the feeding and carding mechanism includes combined feeding rollers (2-4, 2-5, 2-6) having three rotation freedom degrees and multi-level carding rollers (2-8, 2-9, 2-10), the speed ratio of three rollers of the combined feeding rollers (2-4, 2-5, 2-6) having three rotation freedom degrees is adjustable, and therefore the linear density and blending ratio of rotor spun yarn can be regulated and controlled randomly. A rotor spinning method using three- sliver asynchronous input and multi-level carding is also disclosed.
