Abstract:
A spinning machine, comprising:a plurality of spinning places, each said spinning place comprising an air-vortex yarn formation mechanism with which stable fiber material supplied to said spinning place in the form of a longitudinal object is spun into yarn independently at each said spinning place, each said spinning place further comprising a refining mechanism with which the longitudinal object is refined prior to the fiber material being supplied to said yarn formation mechanism; each said refining mechanism independently drivable and controllable with respect to said other refining mechanisms; at least one sensor disposed at each said spinning place to detect at least one measurable property correlated with fiber mass per unit of length; and a control and monitoring unit configured to receive and process data measured by said sensor, said control and monitoring unit operatively configured with said refining mechanism at an associated said spinning place for control of said refining mechanism as a function of said property detected and measured by said sensor independent of refining mechanisms at other said spinning places.
