Abstract
A method of controlling a roving frame to produce good quality results with fewer procedural interruptions and without knowing precise parameters of the textile material being processed. To this end, optimum roving tension during the laying down of each roving layer on a bobbin is successively determined from nominal values for bobbin rotational speed based on only a one-time estimate of material parameters.
