摘要:
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.

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).
摘要:
This invention relates to a heddle formed in a metal band or strip which comprises an eyelet for passage of a warp yarn and presents, over substantially the whole of a zone included between this eyelet and a first end by which it is connected to a drive means, a cross-section substantially in the shape of a Z, with two branches substantially parallel to each other.
摘要:
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.

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).
摘要:
A heddle for guiding a warp yarn for a loom extends lengthwise along a longitudinal axis (X4) and is formed by an assembly of a heddle body including at least one strand, and an eye including an eyelet for the passage of a warp yarn, and defining a main plane (P) wherein a first part of the strand and the eye is provided, before assembly, with an end part a second part of the strand and the eye is provided, before assembly, with a cavity for receiving the end part arranged at a longitudinal end of the second part and wherein the receiving cavity is provided with a bottom and emerges on an outside of the second part, along a transverse axis (Z4) perpendicular to the main plane (P).

A heddle for guiding a warp yarn for a loom extends lengthwise along a longitudinal axis (X1) and has a heddle body including at least one strand and at least one eye including an eyelet for the passage of the warp yarn and wherein the heddle body includes at least one housing, the housing of the eye and the housing of the heddle body extend along a common axis (Z1) transverse to the longitudinal axis, the housing of the heddle body is across from the housing of the eye, and the housings together forming a pair of housings and wherein an assembly member made from solidified resin is positioned in the pair of housings.
摘要:
This process includes steps consisting in manufacturing an eyelet for guiding a warp yarn, making, in a threadlike element, an opening for receiving the eyelet, and placing and immobilizing the eyelet in the opening. During manufacture of the eyelet at least two projecting tabs offset from each other along its edge and perpendicularly to the principal faces of this eyelet are formed on this outer edge. During the placement of the eyelet in the opening, a part of the edge of the opening is inserted between the tabs. As a variant, the tabs can be provided on the edge of the opening.
