Abstract (en)

[origin: EP3327184A1] A multi-level carding rotor spinning method and device. The device 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 feeding and carding mechanism includes combined feeding rollers (2-5, 2-6, 2-7, 2-8) having four rotational freedom degrees and multiple levels of carding rollers (2-10, 2-11, 2-12). The speed ratio of four rollers of the combined feeding rollers having four rotational freedom degrees can be adjusted, so that the linear density and the blending ratio of rotor spun yarns are randomly adjusted.
