PURPOSE: To obtain an accurate production by plural spinning machine frames in a given time.
CONSTITUTION: Each of a large number of fine spinning frames arranged in a row is equipped with a control device 2, respectively and the control device 2 is provided with a pulse counter for counting the number of revolutions of a front roller. These control devices 2 are connected through a local area network L to a host computer 5, respectively. Each control device 2 successively operates production based on the number of counts of the pulse counter to memorize the production in a memory region of a production counter set in the control device 2. When a switching command signal from the host computer 5 is outputted, the memory region to memorize production is changed.
