Abstract: A method of controlling and maintaining a drawing force applied to a length of rolled stock between two-spaced apart rolling units includes the steps of determining the value of at least one of a frequency and an amplitude of a transversed vibration of the rolled stock between the drawing units, correlation of the determined value to a corresponding value of drawing force, comparison of the correlated value of the drawing force to a reference value, and adjustment of the drawing force to maintain it at a substantially constant selected value. In another aspect of the invention an apparatus is provided which includes elements for measuring at least one of a frequency and an amplitude of a traversed vibration experienced by a length of rolled stock between two drawing units, a unit for correlating the measured value to a corresponding value of applied drawing force, and a control unit for adjusting the applied drawing force as necessary to maintain it substantially at a selected constant value.
