Abstract
The fiber material (of which a yarn is to be spun) is drawn and combed after carding. In order to determine the combing intensity, a sample is taken from the fiber material after carding and is subjected to an analysis for fiber length and/or impurities. Certain limits are set for fiber length and/or impurities and the combing intensity is adjusted according to the results of the analysis. The fiber material treated with this combing intensity is again drawn and is then opened into individual fibers which are incorporated into a continuously spun and drawn-off yarn.
