Abstract (en)

[origin: EP1350870A2] The equipment includes a controlled drawing section (1), and a carding- or comb machine fed continuously with fibrous bands (2). A sensor (3) ahead of the drawing section, measures band thickness. An exit sensor (30) measures thickness of the resulting fibrous band (2') in a first drawing operation. Measurements are also taken in a second defined drawing operation which is not normally used. A computer (14, 14') compares values. The control unit (10) coordinates and optimizes adjustments with machine and/or fiber characteristics. The first drawing section is used for normal high delivery speed, fibrous band production. In the second drawing section operation, a test may be performed to establish the control magnitude for drawing. Simulated voltage signals may be imposed on the controller to drive (13) loop, corresponding with variations in band thickness measured at the entry sensor. Further optimization features are elaborated. An Independent claim is included for the corresponding control optimization method.
