Abstract (en)

Control systems and methods are described which are particularly suitable for spinning mills. In particular the control methods and systems are designed to regulate and control foreign fibers and materials which may be found during the spinning process. To reduce the number of foreign fiber detectors some machines (8) may be provided without a detector. Bad quality or very good quality material may be sent to such a machine. Intermediate quality product may be sent to machines (2, 4, 6, 10) with foreign fibre detectors (12, 14, 16, 20). The control systems and methods also foresee both upstream and downstream control. This may include changing the settings of detectors on one or more machines )2, 4, 6, 8, 10) to optimize the operation. To assist in this process it is preferred if quality data is stored at each processing machine (2, 4, 6, 8, 10) in a label 17, 19 which may be applied to work-in-progress (15) or may be stored in a centralized computer (31). <IMAGE>
