Abstract
A spinning machine includes a plurality of spinning stations or places. Each spinning place includes a yarn formation mechanism that is supplied with staple fiber material in the form of a longitudinal object. Each spinning place includes a refining mechanism by way of which the longitudinal object is refined prior to the fiber material being supplied to a yarn formation mechanism. Each refining mechanism is independently drivable and controllable with respect to the other refining mechanisms. At least one sensor is disposed at each of the spinning places to detect at least one measurable property correlated with fiber mass per unit of length. A controlling monitoring unit is configured to receive and process data measured by the sensor. A control monitoring unit is configured with the refining mechanism at the associated spinning place for control of the refining mechanism as a function of the property detected and measured by the sensor independent of the refining mechanisms at other spinning places.
