Abstract
A method and an apparatus for the regulation of the warp let-off of a weaving machine is proposed, in that a desired speed of rotation (S.sub.D) is predetermined for a warp beam (2), in that a warp tension (K) of the warp threads (3) which are given off by the warp beam (2) is determined, in that the warp tension (K) is weighted with a weighting function (G) and in this manner a weighted warp tension (K.sub.G) is determined, in that a corrected desired speed of rotation (S.sub.DK) is determined from the values of the desired speed of rotation (S.sub.D) and the weighted warp tension (K), and in that the speed of rotation of the warp beam (2) is controlled in dependence on the corrected desired speed of rotation (S.sub.DK).
