    • Frame-driving unit for weaving looms equipped with a programming unit, said triving unit being of the type wherein a kinematic chain is provided, between said programming unit (3) and a frame (4), which kinematic chain at least consists of a rocking arm (5) subject to said programming unit; a flexible connection (8) between this arm and a second lever (6) which is mounted to a fixed part (1) of the loom; a rod (10) between said second lever (6) and a frame (4); and of a spring means (11) making contact with said second lever, characterized thereby that the geometry of the various points of rotation and connection (7, 9, 12, 13, 14) of said chain has been chosen in such a way that every rotation of said rocking arm (5) occasioned by the programming unit results in a positive downward movement of the frame (4).
    • 在所述编程单元(3)与框架(4)之间设置有编程单元的织机的框架驱动单元,所述修整单元为设置有运动链的类型,所述运动链至少由摆动 手臂(5)受所述编程单元的限制; 该臂与安装在织机的固定部件(1)上的第二杠杆(6)之间的柔性连接(8) 在所述第二杠杆(6)和框架(4)之间的杆(10); 以及与所述第二杠杆接触的弹簧装置(11),其特征在于,所述链条的各个旋转点和连接(7,9,12,13,14)的几何形状已经以这样的方式选择: 由编程单元引起的所述摇臂(5)的每次旋转导致框架(4)的正向下移动。
