Abstract (en)

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).
