Abstract (en)

[origin: EP3686330A1] A spinning method is executed by a spinning machine (1) in which a yarn (Y) is produced by drafting a fiber bundle (S) by a draft device (6) and spinning the drafted fiber bundle (S) by a pneumatic spinning device (7). The spinning method includes: a first acquiring step of acquiring fiber bundle information indicating a status of the pre-drafted fiber bundle (S); a second acquiring step of acquiring yarn information indicating a status of the produced yarn (Y); and a changing step of changing a total draft ratio of a drafting operation performed in the draft device (6) in accordance with the fiber bundle information acquired in the first acquiring step and the yarn information acquired in the second acquiring step.
