ABSTRACT:
A loom having left and right warp beams and a common tension roller is provided with an electric or mechanical control system, which detects forces exerted on left and right supports of the tension roller by the warp threads of both warp beams, and produces a left control signal corresponding to a tension of the warp threads of the left warp beam and a right control signal corresponding to a tension of the warp threads of the right warp beam in accordance with the detected forces. The rotational speeds of the left and right warp beams are controlled individually in accordance with the left and right control signals, respectively.
