Abstract
A method of directly determining setting values for an application point of regulation in a draw unit for drafting sliver includes the following steps: obtaining a plurality of measured values of a quality-characterizing magnitude, such as a CV value, of the drafted sliver; utilizing the measured values for formulating a function having a minimum constituting an optimal application point of regulation for controlling the draw unit; determining the optimal application point of regulation in a pre-operational run of the draw unit; obtaining measured values of at least two quality-characterizing magnitudes based on the drafted sliver; combining values of the quality-characterizing magnitudes at the sliver, which correspond to one another with respect to the application point of regulation, to a quality-characterizing number QK, and forming a function based on several numbers QK. The function has a minimum corresponding to an optimal application point of regulation R .
