Abstract: In a weaving system in which the selection of the hooks is effected by rotation of their shanks so as to present their nose elements to the blades of the gripper frames or, on the contrary, to retract them, each hook comprises at its end a flat eyelet which, when it returns into its low rest position, engages in a depression with elliptic inlet in a bottom board and which tends to return it to the correct angular orientation corresponding to this position. In addition, to each eyelet is attached an elastic blade which passes through a slit in a guiding board and which acts in the manner of a return torsion spring to complete the effect of the depression.

Abstract: It comprises a grid incorporating inclined bars (13) for bending the needles (5) so that they pass above a lateral lug (8c) of the corresponding small needle (8) provided to be flat. Each small needle comprises a fine tail (8b) guided by a perforated panel (12) on which it rests in the free state by being loaded by the needle (5) which passes through a perforation (11a) in a plate (11). The paper (9) is raised in the direction of the small needles with a view to selection.

Abstract: An improved hook for a double-lift open shed Jacquard machine, each hook having first and second oppositely facing catches and having a boss for contacting in the low position of the hook a finger of the machine to displace the hook so that one of the catches engages a gripper of one frame, the boss being so located that the hook when in low position in displaced when pressed transversely by a needle so that the other catch engages a gripper of the other frame.
