Shedding Machine for a Loom and Adjusting Method Thereof
A shedding machine includes an eccentric system rotatable about a main axis; a lever; and a transmission rod, coupled to the eccentric system and pivotally to the lever about the eccentric axis and connecting rod axis spaced apart by a connecting rod center distance, the main axis and the eccentric axis being spaced apart by an eccentric center distance. To facilitate the adjustment of the stroke of a heald frame operated by the machine, which includes an adjustment system, allowing an adjustment configuration where the eccentric distance or connecting rod distance is adjustable, and a locked configuration where these distances are fixed. The machine also includes a locking system, which allows lever locking and lever release configurations.
PULLING MECHANISM FOR CONTROLLING THE HEALD FRAMES OF A LOOM AND LOOM COMPRISING SUCH A MECHANISM
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).

Shed forming machine and loom including such a machine
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.

SHEDDING MACHINE FOR A LOOM AND SHEDDING ASSEMBLY FOR A LOOM COMPRISING A GROUP OF SUCH MACHINES
The present invention relates to a fluidic connection device, comprising a flange, and a nozzle through which passes a distal internal channel, and which is configured so as to be fluidically coupled to a complementary connection device. The nozzle, mounted in the flange with the possibility of tilting relative to the flange, comprises a rear end, and a front end. The invention also includes a rod comprising an intermediate internal channel; a front end, mounted in sealed cooperation with the rear end of the nozzle with the possibility of tilting of the rod relative to the nozzle and relative to the flange, for fluidic communication between the distal internal channel of the nozzle and the intermediate internal channel of the rod; and a rear end for fluidic communication between a proximal internal conduit and the intermediate internal channel.
