A volumetric weaving approach employs a vertical aspect of woven warp and weft fibers to generate volumetric structures through formation of tie-downs. Tie downs define warp and weft fibers that take a vertical path or component extending perpendicular to a weave plane. Independently controlled heddles provide selective warp fibers control, and a two-dimensional creel that dispenses the warp fibers at differing feed rates allows manipulation of the fibers into three dimensional structures or portions. As a shuttle draws the weft fiber, different layers are raised and lowered to lend a vertical axis to the resulting volumetric structure. Interconnections between the portions include the use of the tie downs to connect multiple portions to define 3-dimensional panels of a finished article such as a shoe. A single pass defining all the interconnected portions of the shoe generates the fully formed shoe without subsequent cutting and seaming of different textile panels.

This heddle for a harness of a Jacquard weaving loom comprises two strands (32, 34) each equipped at a first end with a member for hooking-up the heddle to an element 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 (X10) of the heddle, between both strands (32, 34). The link (30) is in a synthetic material and comprises two branches (52, 54) positioned on either side of the eyelet (36) along the longitudinal axis (X10). 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 over-molded portion of the branch of the link relatively to the second end of the strand along two opposite longitudinal directions (F1, F2), while the eyelet (36) is formed with the synthetic material which makes up the link (30).

A heddle (10) is provided for weaving strip-shaped warp yarn. Said heddle (10) includes a heddle shaft (12) formed by two shaft parts (13). Said shaft parts (13) are placed on top of each other in a respective end section (15) of the heddle shaft (12) and interconnected. The end eyelets (16) of the heddle (10) are also in said end section (15). To form a yarn eye between both shaft parts (13), two separate warp yarn guiding bodies (20) are placed therebetween. To determine the position of the warp yarn guiding body (20) with respect to the heddle shaft (12), at least one shaft projection (22) is produced by stamping and subsequent bending or embossing each shaft part (13) for each warp yarn guiding body (20). Said shaft projection (22) engages in an associated recess (25) of the warp yarn guiding body (20), and a bonding connection is produced.

A Jacquard heddle comprising a link, comprising an upper hole and a lower hole of circular cross-section. A first single-filament wire is engaged in the upper hole forming an upper loop and a second single-filament wire is engaged in the lower hole forming a lower loop. The Jacquard heddle comprises an upper end connector to which two end portions of the first wire are linked and a lower end connector to which two end portions of the second wire are linked. The upper loop defines a free opening extending from the upper hole to the connection of the two end portions of the first wire with the upper end connector. The lower loop defines a free opening extending from the lower hole to the connection of the two end portions of the second wire with the lower end connector.

This heddle includes a link and at least one rod made of polymeric material, one longitudinal extremity of which includes 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.

The present invention provides a heald suitable for use with various types of weaving looms. The heald is constructed from plastics having two distinct colors which meet around the middle of the heald so that each color includes an eye for guiding the warp threads. The edges and sides of the heald are arced and radiused to reduce friction from passing up and down through the yarns to allow for faster machine operation. In some embodiments, the top end of the heald is constructed and arranged to grip the operational cords typically used on a Jacquard weaving machine. The grip end of the heald includes a sinusoidal path and alligator like teeth to prevent slipping of the cords.

The present application belongs to the field of textile technology and particularly relates to a shedding mechanism structure, a weaving machine including the same, a fabric, and a method for weaving fabric. The shedding mechanism structure includes independently liftable shedding arms and half shedding frame. The shedding arms include a front base shedding frame and a rear base shedding frame, the front base shedding frame and the rear base shedding frame are each provided with a movable part. The movable part is provided with a movable hole, the half shedding frame is liftably mounted between the front base shedding frame and the rear base shedding frame through the moveable hole.
