Device to a regulating draw frame for the direct determination of setting values for the promoter use point

摘要

In the case of a device to a regulating draw frame for the direct determination of setting values for the promoter use point at which the control of the adjustable distance in the distortion of fiber sliver has at least one pilot control, in order to change the drawing of the fiber sliver are, on the basis of the drawn fiber sliver a plurality of measured values of a quality characteristic quantity, such as cv - value, can be accommodated and can be used for determining a function, the minimum an optimum promoter use point for the control of the distance is obtained and the optimized adjusting point is used in a preoperational test - or adjustable running of the distance can be determined. Dollars a by the determination and setting the optimum promoter use point on a regulating device of the draw frame to improve the basis of the unstretched fiber sliver are a plurality of measured values of a quality characteristic quantity, such as cv - value, can be accommodated and, the function between the quality characteristic quantities, such as, cv - value, and the promoter use of points from the measured values at the unstretched the fiber band and can be determined on the drawn fiber sliver.
