Needle-eye Heddle Patents (Class 139/53)
  • Patent number: 11047070
    Abstract: A clamping apparatus provides a releasable connection of a harness cord to a lifting heddle of a leno weave apparatus, wherein the releasable connection is configured as a clamping connection. The clamping apparatus has a clamping wedge and a wedge receiver device arranged at the end of the lifting heddle. The wedge receiver device displaceably receives the clamping wedge in the longitudinal direction of the lifting heddle. The harness cord is clampingly grippable between the wedge receiver device and the clamping wedge structure is provided for fixing the clamping wedge in the clamping receiver device.

  • Patent number: 7493921
    Abstract: A heald having a heald body (8), whose thickness increases toward the yarn eyelet (6). The lateral surfaces of the heald body (8) constitute guiding surfaces which are oriented in the warp yarn direction and which, adjacent the yarn eyelet (6), serve as spacers (35, 36) for holding at a distance adjoining yarn eyelets (6) of adjoining healds.

  • Patent number: 7469723
    Abstract: 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.

  • Patent number: 7451787
    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).

  • Patent number: 7451788
    Abstract: An apparatus for weaving leno fabric on a loom including a support pivotally mounted on a loom, and carrying a plurality of ground thread blades arranged side by side in a row and spaced apart to define guide spaces therebetween for ground threads. A leno guide blade divides each guide space into first and second guide slots, each leno guide blade having a leno guide eye through which a leno thread is guided, adjacent ground thread blades projecting beyond the terminal end of the leno guide blade located therebetween to define a ground thread cross-over space.

  • Patent number: 7438092
    Abstract: A loom, especially an air jet loom for producing a leno cloth with integrated patterning includes a weaving reed and first and second shed forming devices. The first shed forming device includes a pivotable reed as a first guide arrangement for guiding and shedding leno warp threads, and an upright reed as a second guide arrangement for guiding and shedding ground warp threads, to form leno bindings. The second shed forming device includes a third guide arrangement for guiding and shedding patterning warp threads, to form pattern bindings. The third guide arrangement is arranged between the first shed forming device and the weaving reed.

  • Patent number: 7287554
    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.

  • Patent number: 7225838
    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.
