Abstract

This heddle comprises a link and at least one rod made of polymeric material, one longitudinal extremity of which comprises surfaces covering the transverse faces of the link. The rod and the link form at least one cavity, offset from the link parallel to a longitudinal axis and delimited by a first peripheral surface of the link, a second lateral surface, formed by the outer surface of the rod, and a third bottom surface, formed by the rod and extending one of the covering surfaces. An intersection line extends from the third bottom surface and delimits the first surface. The third bottom surface is arranged toward the outside of the rod relative to the second lateral surface. Each cavity is non-facing, according to a thickness axis in a direction away from the third bottom surface.

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.

Abstract

Cette lisse pour harnais de métier à tisser Jacquard comprend deux brins (32, 34) équipés chacun à une première extrémité d'un organe d'accrochage de la lisse à un élément du harnais, ainsi qu'un maillon (30) avec un illet (36) de guidage d'un fil de chaîne, cet illet (36) étant disposé, le long d'un axe longitudinal (X10) de la lisse, entre les deux brins (32, 34). Le maillon (30) est en matériau synthétique et comprend deux branches (52, 54) disposées de part et d'autre de l' illet (36) selon l'axe longitudinal (X10). Une partie (522, 542) de chaque branche (52, 54) est surmoulée sur une deuxième extrémité (324, 344) d'un brin (32, 34) opposée à sa première extrémité et décalée longitudinalement de l' illet (36). En outre, chaque branche (52, 54) du maillon entoure complètement la deuxième extrémité (324, 344) du brin correspondant (32, 34). La deuxième extrémité du brin (32, 34) est conformée avec une géométrie destinée à réaliser un ancrage qui s'oppose au déplacement de la partie surmoulée de la branche du maillon par rapport à la deuxième extrémité du brin selon deux directions longitudinales opposées (F1, F2), alors que l' illet (36) est formé par la matière synthétique qui constitue le maillon (30).

Abstract

Heddle for a harness of a Jacquard weaving loom having two strands (32, 34) each equipped at a first end with a member for hooking-up the heddle to an element 10 of the harness, as well as a link (30) with an eyelet (36) for guiding a warp thread, this eyelet (36) being positioned, along a longitudinal axis (XI0) of the heddle, between both strands (32, 34). The link (30) is in a synthetic material and has two branches (52, 54) positioned on either side of the eyelet (36) along the longitudinal axis (XI0). A portion (522, 542) of each branch (52, 54) is over-molded on a second end (324, 344) of a strand (32, 34) opposite to its first end and shifted longitudinally from the eyelet (36). Further, each branch (52, 54) of the link completely surrounds the second end (324, 344) of the corresponding strand (32, 34). The second end of the strand (32, 34) is conformed with a geometry intended to achieve an anchoring which opposes the displacement of the overmolded portion of the branch of the link relatively to the second end of the strand along two opposite longitudinal directions (FI, F2), while the eyelet (36) is formed with the synthetic material which makes up the link (30).

Abstract

A device for hooking a heddle of a weaving loom of the Jacquard type to a harness cord of the loom that includes an endpiece molded on an upper end of the heddle. The endpiece including an aperture for the passage and wedging of the cord and a housing for receiving two strands of the cord. The device also includes a rigid sleeve reciprocally slidably mounted on the endpiece between a first position, in which it allows access to the aperture, and a second position, in which it covers the aperture and exerts a compressive force for constricting the aperture and blocking access to the lower end of the cord. The device may also be used for hooking one or more cords on a string.
