ABSTRACT:
A process for direct ascertainment of setting values for point of autolevelling and/or amplification application (R, K) of a draw frame or carder with adjustable drafting of fiber sliver in which the autolevelling of the adjustable draw frame or carder is provided at least with one pilot control (10) in order to change the drafting of the fiber sliver (20) is proposed. The process accelerates optimation but not so that it may produce an inherent restlessness in the autolevelling of the draw frame. This is achieved if a function (a, b) is found through several measured values (CV1, CV2, CV3) of a quality-characterizing magnitude such as CV-value, the minimum of which (am, bm) results in an optimizing parameter such as the point of autolevelling or amplification application (R0, K0) for the autolevelling (10) of the draw frame or carder.
