Abstract: A mechanism for selecting and raising heddle hooks in a weaving loom in response to control signals delivered by a pattern reader, wherein the mechanism includes a flexible blade for each hook and further includes a catch associated with each blade and operable to connect the blade with the hook thereby to select the hook, and the mechanism further including an electro magnetic coil operative for selecting each blade and catch in response to said control signals delivered to a shift register whose stages energize the coils, the hooks being supported by one plate and the selecting mechanisms being supported by another plate, the plates reciprocating toward and away from each other in synchronism with the loom motion.

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.
