Patent number: 7287554Abstract: 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.Type: GrantFiled: July 13, 2006Date of Patent: October 30, 2007Assignee: Groz-Beckert KGInventor: Oliver Hans Mathews

Method for producing a fabric in plain weaves and leno weaves and a loom for carrying out the method
Patent number: 7225838Abstract: 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.Type: GrantFiled: February 18, 2004Date of Patent: June 5, 2007Assignee: Lindauer Dornier Gesellschaft mbHInventors: Adnan Wahhoud, Peter Czura -

Patent number: 5078183Abstract: 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.Type: GrantFiled: October 29, 1990Date of Patent: January 7, 1992Inventor: Eve T. Broughton
