Abstract (en)
[origin: CN114645362A] The invention relates to a shedding mechanism and a jacquard loom equipped with the shedding mechanism. The opening mechanism comprises a housing, at least one movable hook that can be held by a selection device, the selection device comprising at least one electromagnet and comprising a ferromagnetic core comprising a first pole face and a second pole face, the pole faces being offset from each other along a longitudinal direction. The electromagnet further includes a non-magnetic portion and a retaining lever configured to retain the movable hook when the movable hook is in or near its top dead center position, the retaining lever being mounted to pivot about a swing axis between a position away from the electromagnet and a position in contact with the electromagnet. The non-magnetic portion of the electromagnet includes a surface for guiding the pivoting of the retaining bar about the pivot axis, the guiding surface cooperating with the retaining bar in a direction radial to the pivot axis between a distant position and a contact position. The guide surface is cylindrical with a circular base centered on the pivot axis.
