Abstract
A method and device for forming a warp beam of uniform diameter by feedback control of winding tension, in which a signal obtained from local winding tensions, each corresponding to a tension of a yarn at a certain widthwise position, are utilized for adjusting the position and width of a reed so that distribution of the warp on the beam is improved and an intra-beam diameter difference is compensated. One of the signals obtained from the local winding tensions is utilized for adjusting the rotational speed of rollers so that an inter-beam diameter difference is compensated. Thus, a warp beam without intra- or inter-beam diameter difference can always be produced.
