  • 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.

    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.

  • Patent number: 7036532
    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.

  • Patent number: 5078183
    Abstract: A loom-controlled leno or cross-weaving system, alone or in conjunction with tabby or ordinary weaving. The leno heddle is composed of two upright members, each connected to two flexible cross-members. Each upright member is connected to a separate, independently moving portion of the loom frame. Each cross-member has an eye in the middle for the passage of the warp thread. The upper cross-member is positioned below the lower cross-member when the warp threads pass through the eyes. Alternation of the elevation of the upright members causes the warp threads to alternate positions laterally. Leno weaving is achieved with a throw of weft for every alternation of upright member position. Tabby weaving is done using a rising loop and a falling loop, each connected to the loom frame independently. One warp thread goes through the eye of the upper cross-member and also through the rising loop. The other warp thread passes through the eye of the lower cross-member and the falling loop.
