ABSTRACT:
A method of and apparatus for regulating out variations in the sliver weight on processing machines such as cards, carding engines, draw frames and the like wherein a first measuring device measures either the absolute cross-section or the relative variations of cross-section relative to a predetermined fixed desired value of a fibre sliver issuing from the machine. The first measuring device forms a corresponding first test signal. An additional measuring device is arranged at a point upstream of the first measuring device with respect to the direction of travel of the fibre material. The additional measuring device produces a second test signal corresponding to the relative variations in the cross-section of the fibre material relative to an average value for these variations formed over a predetermined period. The first and second test signals are used for controlling at least one regulating device which controls the cross-section of the fibre sliver.
