This pulling mechanism for controlling the heald frames of a loom equipped with a shedding machine comprises a set of connecting rods and oscillating levers (72) coupled to the set of connecting rods, for each heald frame, for returning a movement of the shedding machine to the heald frame. The pulling mechanism comprises at least one measuring portion (72C), equipped with a target (100) configured to interact with a sensor (110). For easier mounting and dismounting of the targets on the measuring portions, each measuring portion is provided on a peripheral wall of one of the oscillating levers (72), or a stabilizer of the pulling mechanism, the target being reversibly mounted on the measuring portion (72C).

A machine for forming the shed of a weaving loom, of the dobby or cam machine type utilizes output levers performing, during the weaving, an alternating oscillation movement around another common shaft, a casing (12) with an output aperture crossed by the levers, as well as a frame (6) which delimits, with the casing (12), an inner volume (V) of the machine, including an area for receiving torque transmission members between a driving shaft and a shaft for actuating the output levers as well as an area for receiving the output levers, this receiving area being adjacent to the area for receiving the torque transmission members, while the frame (6) supports the actuation shaft. The casing (12) and the frame (6) are in sealed contact, via at least one seal gasket (16, 18), at both external (16) and internal (18) seal barriers (B1, B2) respectively distant from each other, both seal barriers each extending over the whole periphery of the casing (12) except at the output aperture.
