ABSTRACT:
A method and apparatus for a textile carding machine or drafting machine drawframe having an out-of-round or otherwise imperfect rotating member is based on detecting and analyzing the relative rotative positions of selected of the machines rotating members in relation to the moment to moment weight of the sliver output and developing therefrom a control signal for varying the speed of rotation of a rotative feeding member so as to vary the sliver weight to compensate for such imperfections.
