Abstract (en)

[origin: EP3438334A1] A fine spinning machine includes a back roller 16, an air spinning device, a first motor 81, and a control part 100. The back roller 16 feeds a sliver. The air spinning device produces a spun yarn by twisting a fiber bundle made from the sliver with airflow. The first motor 81 drives the back roller 16, and its rotation amount is controlled in accordance with a command signal. The control part 100 calculates a consumed length of the sliver based on the command signal.
