    • To maintain constant the tensions in warp yarns fed from a yarn beam of the negative let-off motion type of a loom, an improved warp tension control mechanism is herein proposed which consists of a brake unit adapted to exert a substantially constant braking torque on the yarn beam and a brake control unit which is responsive to variation in the tensions in the warp yarns being fed from the yarn beam and which is operative to lessen the braking torque on the yarn beam in response to an increase in the tensions in the warp yarns as caused by the stepwise reduction of the outside diameter of the roll of the yarns on the yarn beam and by any unforeseen operational conditions of the loom during weaving operation.
    • 为了保持从织机的负送纸运动类型的纱线束供给的经纱的张力恒定,本文提出了一种改进的经纱张力控制机构,其包括一个制动单元,该制动单元适于在其上施加基本恒定的制动转矩 纱线束和制动控制单元,其响应于从纱线束供给的经纱中的张力的变化,并且其可操作以响应于经纱中的张力的增加而减小纱线束上的制动扭矩 这是由于在纱线束上的纱线的辊的外径逐渐减小以及编织操作期间织机的任何不可预见的操作条件引起的。
