A cascade spinner process is controlled by monitoring the torque ratio on one or more of the fiberising rotors (7, 8, 9, 10) which are rotating at a preselected speed, and adjusting the conditions on the first rotor (7) in response to deviations of the monitored torque ratio from a predetermined target torque ratio. The torque ratio is generally a ratio of torque on one rotor (usually the last rotor) to the torque on one or more other rotors. |
