ABSTRACT:
A loom having harnesses carrying an array of warp yarns defining a warp direction and displaceable in a shed direction transverse to this warp direction to form a main shed adapted to receive a weft passed through the shed in a weft direction transverse to the warp and shed directions has a leno selvage device. This device comprises at least one ground heddle at an edge of the array of warp yarns which carries a ground warp yarn. There is also provided a doup heddle at this edge which carries a doup warp yarn. One of these heddles is displaced synchronously toward the other heddle with the harnesses of the loom to form an edge shed in line with the main shed. A support is provided which defines a rocking axis nondisplaceable in the weft direction and a rocker is pivotal on the support about this axis between a pair of end positions. The doup heddle is operatively engageable with this rocker and can be deflected thereby in the weft direction to either side of the ground heddle. On each shedding operation the rocker is moved from one to the other position so that the doup heddle is alternately deflected to one side and the other of the ground heddle so as to form a leno selvage at the edge of the woven goods.
