A sliding nut (20) for a dobby lever of a textile loom, which can be inserted into a main lever (11) which consists of a pair of parallel flat sides (12,13), separate but fixed to each other, where the sliding nut (20) comprises a body which can be inserted between the sides (12,13), at one end of which is a hole (22) suitable for receiving a joint which can be connected to a driving bar and at the other end a relative blocking device for the sides, the body being shaped at the second end (25) to receive sloping surfaces on which there are wedge-shaped elements (28), in a complementary slanting position, which can be inserted into a box-shaped container (30) and acting upon the sides, a screw element (34) being applicable to the box as a blocking device to determine the performance of the wedge-shaped elements (28) with respect to the sloping surfaces and sides at the main lever. <IMAGE> |
