Abstract (en)
[origin: EP1211340A2] To set the sliver drawing action, at a spinner, the drafting is adjusted according to measured values e.g. the thickness, and the mass etc. of the fiber material, to give constantly monitored measurement of the optimum control action points in operation. To set the sliver drawing operation, at a spinner, the optimum control action points are taken by the spinner control unit, to set the working for a consistently drawn sliver to be used for spinning. The optimum control action points are computed together with mathematical algorithms, which take into account variations in the sliver thickness and the drawing characteristics of the sliver fibers. The mathematical algorithms are in the form of transfer functions or discrete value pairs. The computed control action points are returned to the control unit to adjust the control position, and the drafting is modified at the main drafting zone of the sliver drawing unit. An Independent claim is included for a sliver drawing unit, at a spinning machine, with a monitor (1) to give continuous measurements of the sliver (6) e.g. the sliver thickness, fiber mass, and the like, to be passed to the control unit (2).
