    • A warp stop motion device of a weaving machine has upper and lower supports respectively for contact bars and guide bars lying in transversely spaced vertical planes with vertically extending legs thereon having adjustment and locking means to facilitate a clamped vertical adjustment between the upper and lower supports. The lower supports are cantilevered at one end to a longitudinally extending beam serving as a warp end carrying support, and the upper supports are cantilevered at one end to the one end of the lower supports. Thus, the opposite ends of the upper and lower supports are free and unsupported for the reception of the guide bars from such ends during assembly.
    • 编织机的翘曲停止运动装置具有分别用于接触杆和位于横向间隔开的垂直平面中的引导杆的上部和下部支撑件,其上具有垂直延伸的腿部,其上具有调节和锁定装置,以便于在上部和下部支撑件之间进行夹紧的垂直调节。 下支撑件在一端处悬臂连接到用作承载支撑件的经向端的纵向延伸的梁,并且上支撑件在一端悬臂连接到下支撑件的一端。 因此,上部和下部支撑件的相对端部是自由的并且不被支撑,用于在组装期间从这些端部接收导杆。
