    • To move pile heddle frames between three or rather four shed positions, a four-position rocking lever is arranged between two adjacent heddle frame lifting units and the rocking lever controlling the heddle frame. The free end of the first lifting unit rocking lever is a hinge point for the four-position rocking lever and the free end of the second lifting unit rocking lever is a hinge point for a connecting bar extending to the four-position rocking lever. To reduce wild movements of the heddle frame, no loaded shafts are provided in the power-transmitting path from the lifting unit to the heddle frame, aside from shafts supporting the lifting units and the rocker arm of the heddle frame.
    • 为了在三个或四个棚架位置之间移动桩综框,在两个相邻的综框提升单元和控制综框的摇杆之间布置有四位摇摆杆。 第一提升单元摇杆的自由端是用于四位摇摆杆的铰链点,第二提升单元摇杆的自由端是延伸到四位摇杆的连接杆的铰链点。 为了减少综框的野外移动,除了支撑提升单元和综框的摇臂的轴之外,在从提升单元到综丝框架的动力传递路径中没有设置负载轴。

    • In a weaving machine a control unit for controlling the movement of the shaft frames or harnesses creates a feedback function through load cells and AC-servo motors that enables accurate shaft frame adjustment in forming an open shed. The weaving machine includes detecting mechanisms that detect parameters regarding condition the shaft frames. An individual control unit controls each of the shaft frames. The control units adjust the shaft frames in one or more positions to create open and closed sheds in the warp threads to enable the weft threads to be inserted by the shuttles as the warp threads change position. The control units receive feedback data of at least one of the parameters from the detecting mechanisms, such that operation of the control units incorporates the feedback data. Control systems control the control units to create a substantially constant level in the butting edge of the fabric irrespective of the positions of the shaft frames.
