Abstract: A heald body fabricated of a round wire and having a round shank with a flattened intermediate or center section (9) that is provided with a widened opening (16) delimited by two legs (14, 15). The area (A1) of the round cross section of the shank (20) substantially corresponds to the sum of the cross sectional areas (A5, A6) of the two legs (14, 15) of the intermediate section, whereby the heald body has a substantially constant cross-sectional area along its length.

Abstract: Healds that consist of a metal ribbon section having the width (B) that is narrower than the total width B+X required for the flat ribbon heald (20). The flat ribbon heald (20) has an essentially non-machined—in any event, not trimmed—edge (9) derived from the metal ribbon section and an edge (10, 11, 12, 13, 14) that has been produced, in the region of the shaft (4) and the transition regions (5, 6), by trimming the metal ribbon section. An outward-directed crank of the shaft (4) creates an enlarged distance (R) between two associate oppositely cranked flat ribbon healds of a heald pair (23) which comprises two oppositely cranked flat ribbon healds (20, 21).
Abstract: The heddle according to the invention, provided in particular for band-shaped warp threads, comprises two bands (5, 6) that extend in vertical direction during use, are arranged at a distance parallel to each other and hold two thread support elements (16, 17) disposed between them. The thread support elements (16, 17) together with the respective flat segments of the bands (5, 6) between them jointly form a flat thread eyelet (18) that is oriented transverse to the warp thread and the longitudinal direction (7) of the heddle. The bands (5, 6) preferably extend with undiminished width up to the heddle support rails (2, 3) and are provided with end eyelets (10, 11, 12, 13) for positioning them on the support rails.
Abstract: An improved heald consists of a flat material, such as tempered steel. It has closed (O-shaped) end eyelets (5, 6) which are one-piece parts of the heald body (4). An edge (10) which extends along the full length of the heald (1), is of entirely straight configuration. In contrast, the oppositely-located edge (11) consists of offset straight portions. A particularity of the heald according to the invention resides in the fact that the openings (15, 16) provided in the end eyelets (5, 6) for receiving the shaft staves are eccentrically arranged, whereby the two webs (17, 18) bordering the openings (15, 16) have unlike widths. With a reduced material input and weight a heald is obtained which, as concerns stability and possibility of utilization in existing weaving systems is at least equivalent to conventional healds.
Abstract: 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.
Abstract: The curling eye heddle of the present invention utilizes a curling eye which permits the warp thread used in weaving to be threaded onto or unthreaded off of the heddle at the level of the sheet of warps. The curling eye heddle also permits individual warp threads to be lifted or depressed above or below the sheet of warps, respectively. A diamond adjacent to the curling eye prevents the curling eye from catching or snagging neighboring warp threads.
