Abstract: In this mechanism (7) a moving hook comprises a body (20) provided with a nose (202) for bearing against a corresponding knife (14), and a flexible blade (21) secured to the body so as to be capable of moving relative thereto and designed to interact with a retaining lever (16) belonging to the selector device. The selector lever (16) forms a ramp (313) over which a portion (214) of the resilient blade (21) slides when the hook (13) is moved in the vicinity of its top dead-center position. The ramp on which the selector lever slides is shaped in such a manner that the component (FA+FB+FC) parallel to the travel direction (X-X?) of the moving hook (13) of the resultant of the forces (RA, RB, RC) acting on the flexible blade (21) when in contact with the ramp (313) in the vicinity of the top dead-center point of its travel and at the beginning of its downward movement (F14), is directed downwards.

Abstract: The invention concerns a device comprising rigid or semirigid shafts (120) and at least a member (200) provided with orifices (203) for the passage and direct guiding in translation and angular positioning of a shaft in its controlled rocking movements (F1). Said member (200) is mobile, with two degrees of freedom relative to the loom frame, in translation (F4), along a direction globally parallel to the direction (A–A?) of the weft yarns, and in rotation (P4), about an axis (Z1Z?1) globally parallel to the translational direction (A–A?) of the shafts. Said member (200) can be positioned (F4, P4) by the warp yarns (103) which pass through the eyelets (127) of the shafts (120) which it guides.

Abstract: Hooks for controlling movement of heddle cords in a Jacquard weaving loom are each displaced by a knife, between a position of top dead center, wherein each hook may be immobilized by a selection device, and a position of bottom dead center. Each hook includes a body provided with a catch that engages a corresponding knife and a metal blade that is relatively movable with respect to portions of the body adjacent the catch and that interacts with the selection device to selectively retain the hook in the top dead position thereof.

Abstract: The invention relates to a shedding device comprising at least one electric rotary actuator having an output shaft (11) that is designed to rotate a pinion (21) which is engaged with a rack (22), said rack being connected to a control heald (3) of a warp end (4) by means of a load transfer element (24).

Abstract: A double-lift weave system comprising a plurality of hooks, each of which is provided with two arms mounted on a base and each of which includes a lift lip adapted to cooperate with one of the knives of two griffe frames moving in phase opposition in a reciprocating movement. The position of each lip is controlled in order to be selectively moveable with respect to a knife by an actuator disposed between the two arms. Each hook further includes two open shed heels which are controlled by the actuator and adapted to cooperate with open shed bars so as to be moveable with respect to the bars. The system is particularly applicable to weaving looms.

Abstract: A mechanism for controlling the reciprocating movement of griffe frames in a weaving loom which includes four crank arms which are mounted offset angularly with respect to one another to a driving shaft associated with the loom. Two short connecting rods and two long connecting rods are connected to the four crank arms with the two short connecting rods being pivotally mounted to one of the griffe frames and the two long connecting rods being mounted to the other of the griffe frames whereby rotation of the driving shaft causes a reciprocating movement of the griffe frames.
