Abstract: A device for forming a leno selvedge has two lifter seats and a metallic approximately U-shaped half heddle with two legs, which are connected by a web, wherein each lifting heddle has a lifting heddle foot having an opening extending in the longitudinal direction of the heddle, wherein the lifting heddle foot at least on one side of the slot at least one magnet, with which the one leg of the half heddle cooperates, wherein the opening extends over the entire height of the heddle foot continuously.

Abstract: A leno heddle includes a pair of elongated shanks, which are removably assembled together in overlying relationship. One of the shanks has configured ends to be removably received within corresponding openings in the other shank. The shank having configured ends can be replaced within the leno heddle without having to remove the other shank from its coupled relationship with the loom's upper and lower leno heddle support bars.

Abstract: The weft introduction needle for a ribbon needle loom comprises a bent arm (20), which may be fixed at one end (22) to a drive element (24) of a ribbon needle loom and comprises a hook (28) at the other end (26), for registering an exposed thread loop. The arm (20) is provided with a guide piece (30) essentially over the whole length thereof, forming a longitudinal slot (32) with the arm (20) for accommodating at least one weft thread. At the end away from the hook (28), the guide piece is connected to the arm (20), by means of a connector piece (34). A guidance element (36) is arranged on the side of the arm (20) facing away from the guide piece (30) in order to improve the guiding of a weft thread loop, extending over only a section of the length of the arm, starting from the vicinity of the hook (28), whereby the guidance element (36) forms a diverter point (35) in the region away from the hook (28), for diverting the free flare (38) of the weft thread loop (6).

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: A loom simultaneously forms a plain weave (16) and a gauze weave (15) in a textile (9) in one weaving cycle. To form the plain weave (16), the adjacent warp threads (1L,2L) that are used to form the upper shed and lower shed are alternately lifted from the lower shed position into the upper shed position and lowered from the upper shed position into the lower shed position by the same drop wire/needle shank (4). To form the gauze weave (15), only the warp threads (2D) that form the upper shed are raised by the drop wire/needle shank (4) from the lower shed position into the upper shed position and lowered from the upper shed position into the lower shed position.

Abstract: A simple removable plastic heddle comprised of a single monolithic plastic body and a mating insertion tool.

Abstract: A device (1) for forming a leno selvedge, said device having two lifting healds (10, 20) and one half heald (30), the lifting healds (10, 20) having a securing element (13, 23; 14, 24) provided respectively at the upper and lower end thereof, said lifting healds (10,20) having, in the region of the lower end, at least one magnet for the foot (31a, 32a) of the half heald (30), each lifting heald (10, 20) having at least one magnet (18, 28) in the region of its upper end, the magnets (18, 28) of the two lifting healds (10, 20) of a leno selvedge device being polarized such that the healds attract each other.

Abstract: A weaving machine for the manufacture of leno cloths, has an element with ground needles, in particular a needle bar. The ground needles form a row in the direction of the longitudinal extent of the element. The side surfaces of the ground needles include an acute angle which is greater than 1° with a normal to the named longitudinal extent.

Abstract: The invention relatrs to a wide-meshed fabric (1) treated with bonding agents. The inventive mesh is made up of bundles (4) consisting of several warop threads (3) and bundloes (6) consisting of several weft threads (5) surrounding the inner meshes (7). The warp threads (3) are interwoven with the weft threads (5) at intersection points (5) of the bundles (4) of warp threads and bundles (6) of weft threads (5) running at right-angles to each other. In order to firmly secure the warp threads and the weft threads, the bundles (4) of warp threads are divided into a first group (4′) of warp threads and a second group (4″) of warp threads and the first group of warp threads crosses over the second group of warp threads threads belonging to the same bundle (4) of warp threads for each mesh (7) thereby forming a half-twist. Similarly, the warp threads (3) of both groups (4′, 4″) of warp threads are interwoven with the weft threads (5), running substantially parallel to each other.

Abstract: The device for detecting breakage of leno threads in leno selvedge devices on looms, the leno selvedge forming device being provided with at least two arms for guiding at least two leno threads, the leno threads being twistable together by virtue of the rotation of the arms, the device (12, 13, 14, 14a) for detecting thread breakage being provided with a facility (13, 14) for determining the natural oscillations of the arms (12) and a loom, more specifically with heald frames, with at least one leno device which is reversible in its direction of rotation and with a facility for detecting breakage of the leno threads, the device for detecting thread breakage being arranged in the front shed (V), more specifically between the leno device (10) and the heald frames (20).

Abstract: Half heald of a leno selvedge with lifting healds, whereas the half heald has two arms that may be joined together on their upper end so as to form a head and that are provided on their lower end with a foot, whereas the foot is magnetically co-operating with the at least one magnet of the lifting heald, and whereas the foot (70, 80) of the half heald (50) is given a shape that allows the magnetic force exerted onto the foot of the half heald in the stroke direction (arrow 100) of the lifting healds (2, 3) to be smaller than in the reverse direction, whereas the foot (70, 80) is provided with an upper end being designed as a border (71, 81) so that the half heald (59) is alternately magnetically brakable by the lifting healds (2, 3).

Abstract: A leno or cross weaving texture is produced with a stationary warp thread and a cross warp thread which is alternately shifted from one side to the other of the stationary warp thread. The method of producing the leno weave includes the steps of providing a line segment of the stationary warp thread which connects first and second planes provided on the respective sides of the stationary warp thread, inclining the line segment of the stationary warp thread so as to cross a weaving plane alternately from an upper side of the first plane to an under side of the second plane, and from an under side of the first plane to an upper side of the second plane, and moving the cross warp thread in a perpendicular direction relative to the weaving plane and above the inclined line segment so that the cross warp thread is caused, during its movement, to slide along the inclined line segment towards the first plane or the second, thus producing the leno weave.
