  • Patent number: 11702771
    Abstract: This shedding mechanism includes a housing and a movable hook which can be retained by a selection device including at least one electromagnet (100) immobilized in the housing and which includes a ferromagnetic core (102) comprising first and second pole faces (S122, S124). The electromagnet (100) also includes a non-magnetic portion (104, 108) and a retaining lever configured to retain the movable hook. The retaining lever is pivotally mounted about an oscillation axis (A144) and includes a ferromagnetic armature (202) that interacts magnetically with the first and second pole faces. The non-magnetic portion of the electromagnet includes a surface (S144) for guiding the pivoting of the retaining lever. This guide surface cooperates with the retaining lever in a direction radial to the oscillation axis (A144) between a remote position and a contact position. The guide surface (S144) is cylindrical with a circular base, centered on the oscillation axis.

  • Patent number: 7490633
    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.

  • Patent number: 5309950
    Abstract: A quick connect coupling for connecting at least one funicular element with respect to the end of a cord, particularly for those of a harness of a weaving loom, to a cord of shed-forming device of the loom, which includes an insert element associated with the cord of the shed-forming device which has at least one crosspiece to which the cord is attached and a bar located below the crosspiece. A clamp is provided for receiving the insert and has two branch elements which are secured to at least one funicular element. The branch elements have hooked free ends which are elastically articulated relative to one another toward the geometrical axis of symmetry of the clamp.
