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.

A weaving machine (1) equipped with a level adjustment device (8) for a plurality of oscillating levers (26), the oscillating levers being provided with cam followers (42) and mounted on a shaft (28) of the levers, the shaft of the levers being movable between a weaving configuration, where the cam followers of the oscillating levers bear against cams (18) of the shedding mechanism, and a level adjustment configuration, where the cam followers of the oscillating levers are separated from the cams of the shedding mechanism. The level adjustment device comprises a level adjustment picking cam member secured to the shaft of the levers. The shedding mechanism further comprises a pad translatable along a fixed axis (X66) between a first position corresponding to the weaving configuration of the shaft (28) of the levers (26) and a second position corresponding to the level adjustment configuration of the shaft of the levers, and at least one level adjustment connecting rod (60) including a first end (84) mounted pivoting on the level adjustment picking cam member around an axis (X84) of the connecting rod parallel to the central axis (X28) of the shaft of the levers and a second end (86) mounted pivoting on the pad around an articulation axis (X86) of the pad parallel to the axis of the shaft of the levers.
