ABSTRACT:
In a method and an apparatus for producing continuous slivers of improved uniformity, open-loop or closed-loop control of the production process is corrected in dependence upon the absolute air humidity measured near the installation. Long-term variations in sliver weight, which have been found to correlate with the absolute air humidity, are obviated.
