Abstract: A heddle (1) for flat, band-shaped warp threads (36) is provided with a thread eyelet (7), for which the width preferably exceeds the height. A thread eyelet (7) of this type prevents a deformation of the band-shaped warp thread (36), in particular a compressing on the sides during the shed formation. In addition, the heddle (1) according to the invention is preferably provided with thread guiding surfaces, which are longer than the thickness of the heddle (1) body (3), relative to the running direction of the warp thread. As a result of these measures, the wear on the heddle (1) as well as the warp thread (36) can be reduced.

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: A heddle for jacquard machines essentially consisting of fiber-reinforced plastic material, with a thread eye formed by a mail or thread eyelet member (12) of a harder material. The heddle body comprises two legs (3, 4). Between the relatively wide thread eye region (5) and the legs (3, 4), ramp sections (6) are provided on the mail, which sections have a length that is greater than the length of the thread eye (1). Preferably, the length is greater than twice the longitudinal extension of the thread eye, and in most cases, is between 10 and 30 mm. As a result of this measure, the wear of the plastic material in the vicinity of the thread eye (13) is kept minimal enough that neither any damage to the stiffening fibers (22) in the body of plastic material nor any damage to the warp threads needs to be feared.

Abstract: An inventive heddle for jacquard machines essentially consists of fiber-reinforced plastic material, whereby the thread eye is formed by a mail (12). The heddle body comprises two legs (3, 4). Between the relatively wide thread eye region (5) and the legs (3, 4), ramp sections (6, ) are provided, which sections have a length that is greater than the length of the thread eye (1). Preferably, the length is greater than twice the longitudinal extension of the thread eye. In most cases, said length is between 10 and 30 mm. As a result of this measure, the wear of the plastic material in the vicinity of the thread eye (13) is kept minimal enough that neither any damage to the stiffening fibers (22) in the body of plastic material nor any damage to the warp threads needs to be feared.

Abstract: A heald (heddle) shaft (1) comprises at least one shaft rod (2) on which a damping element (12)is supported on the shaft rod carrier body (15) to be movable in the longitudinal direction of a heald or heddle (8) mounted on a shaft stave or rail (6) carried by the body (15) so as to be moveable toward and away from an abutment surface (26) of the support body (15) and an outer end surface (22) an eyelet of a heald or heddle (8) mounted on the shaft stave (6). By virtue of movably supporting the damping element (12), an alignment of the healds or heddles (8) is improved and facilitated, and a desired damping effect is obtained during the entire motion course of the healds or heddles (8).

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: The invention relates to a method for manufacturing components consisting of one piece which appear in a weaving machine, comprising one or more first and second parts, said parts being manufactured in separate first and second parts and joined together to form a whole by means of processes which practically do not change the cross-section of said parts, said first and second parts have: different mechanical and/or magnetic and/or tribological properties; and/or a different manufacturing method; and/or different shape properties according to their functional requirements in the component.

Abstract: An improved heddle (2), on its end eyelet (7), has a spring means (14) which braces the end eyelet (7) resiliently in at least one direction on a heddle support rail 3. The spring means (14) serves to avoid play between the heddle (2) and the heddle shaft (1). This provision makes it possible to increase the operating speed of power looms.

Abstract: A shaft rod (2) having, particularly in its mid region, a particularly low mass. The shaft rod has an upper ledge (11) and a lower ledge (12) which have a reduced thickness in the mid region of the shaft rod. As a result, the load induced by acceleration forces is significantly less in the mid region than in conventional constructions. By virtue of the reduced acceleration forces, the extent of bending of the shaft rods in the middle is less and therefore a shaft rod of such a structure is better adapted for use in very rapidly operating weaving machines.

Abstract: A heddle (14) of the invention is distinguished by end eyelets (15, 16) of reduced size, with which heddle support rails (6, 7) of reduced cross section are associated. The axial play of the heddles on the heddle support rails (6, 7) is limited to from 0.5 mm to 1.5 mm. The lateral play is in the range of 0.2 mm to 0.5 mm. This system formed of heddle support rails and heddles is especially suitable for particularly rigid heddle shafts for power looms with an extremely high operating speed.

Abstract: A shedding device in a jacquard loom, having a heddle with a retracting spring rigidly anchored in the loom or to the floor for urging the heddle to a lower shed forming position. To suppress the development of resonance in the spring, a core element is provided, which contacts the inside of the spring at points spaced apart from one another and forces the spring to take a course which deviates from the rectilinear. As a result, friction forces that contribute to damping the spring motion are created between the spring and the core element.

Abstract: In a heddle (6), the slender heddle shank (21) has been lengthened, at the cost of the end eyelets (7, 8) and the yarn eyelet region (29). This is accomplished on the one hand by shortening the end eyelet regions (7, 8) to their absolute minimum length and on the other by placing the auxiliary openings (38), which serve to transport the heddles, closer to the end eyelets (7, 8). The radii R in the region of the end eyelets (7, 8) are reduced. Instead of the usual 2 mm width, the heddle shank (21) still has a maximum width of 1.6 mm. The regions (14, 13) of the heddle (6) that protrude past the end openings still have, instead of the usual length of 4 mm, a length of 2.5 mm to 3 mm. Directly around the yarn eyelet (33), the heddle has a width which, as before, is equivalent to twice the width of the yarn eyelet (33). However, the length of this region is shortened to a maximum of twice to three times the yarn eyelet width.

The inner edge facing the heddle support rail may be of elastic material on at least one support bar of the shaft to prevent impact of heddles against the support bar during high stress placed on the shafts.

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 heddle shaft rod (4) described originates in an extruded aluminum profile section with relatively thick side walls, which are removed in some regions and thereby made thinner. This can be done without substantial impairment to the rigidity of the heddle shaft rod, yet as a result a substantial reduction in weight is attained. The removal of material can be adapted to the local load conditions. For instance, it is possible at the ends or other force introduction points to leave unweakened thick walls, while the other regions of the side walls are milled off far enough that a uniform thinner wall thickness is attained. It is furthermore possible to vary the amount of material removed, either in multiple steps or in infinitely graduated fashion. The material removal pertains to a reduction in the wall thickness that is measured transversely to the movement direction of the heddle shaft rod.
