Abstract
A warp feed controller for use in a twin beam weaving machine having a first tension detector for detecting the tension of at least one of the groups of warp yarns fed in sheet-like forms from a pair of warp beams and a first control system for controlling the rotation of one of the warp beams on the basis of the tension deviation from a target tension under detection of the tension by the tension detector. The controller also includes a pair of second tension detectors for detecting the tensions of the warp yarns fed from the warp beams in boundary portions of the sheet-like forms, and a second control system for controlling the rotation of the other of the warp beams on the basis of the tension difference output from the second tension detectors, respectively. The first control system controls the one warp beam so that the tension of the warp yarns becomes equal to a target tension, while the second control system controls the other warp beam so that the tensions of warp yarns in the boundary portions become equal to each other.
