ABSTRACT:
A method and an apparatus for automatically controlling the winding tension of the roving in a bobbin lead roving machine is disclosed. The mean bobbin winding diameter D.sub.B, bobbin r.p.m. N.sub.B and the flyer r.p.m. N.sub.F are measured automatically for one or more operating spindles, and a mathematical equation (N.sub.B /N.sub.F -1).times.D.sub.B =K representative of winding conditions for the roving is solved by automatic operation based upon the above measured values. When the value K thus obtained exceeds a preset control limit, the bobbin r.p.m. is decreased or increased automatically for correcting the value K towards its central setting for automatically correcting the winding tension of the roving.
