LENO HEALDS

Leno Weaving: Leno weaving is particularly applied where open effect fabrics are in demand which, however, must have a solid structure between warp and weft threads. In order to achieve for the weave a non-slip effect, two neighboring warp threads cross over each other.Nowadays, with very few exceptions, the so-called upper shed leno technique is the rule: the leno end passes through the thread eye of the doup, the head of which points upwards; the standard end passes through the thread eye of the doup of an inverted leno heald whose head points downwards. When the leno frames are raised and lowered accordingly, the desired half cross leno effect is achieved. By combining different arrangements of this upper shed cross-weaving, beautiful fabrics can be produced as for instance the symmetrically woven counter leno shown in the pattern of the opposite illustration.Depending on the nature of warp yarn to be woven or the desired opening of shed, TRANSALLY can offer suitable leno healds with lifting healds of synthetic material or stainless steel. Leno Healds:The proven combination of materials ¨C synthetic lifting healds, doup healds of steel ¨C and the proper shaping are responsible for the excellent performance characteristics of TRANSALLY leno healds. The broad center part of the lifting healds guarantees an excellent guiding of the doup heald. The head of the doup heald is effectively covered, so that the standard end is not obstructed during shed change, and hence a clean leno binding is ensured. An additional advantage of the combination of synthetic material and steel is: soiling of the fabric by metal abrasion and frictional corrosion are things of the past. The risk of smearing is also averted. TRANSALLY leno healds are particularly suited for glass fiber, cotton and woolen yarns. Leno healds with laterally open C and J-shaped end loops are also available with lifting healds of steel ¨C this especially in view of the processing of hard or high-twist warp yarns or tapes.Thanks to the small metal plates welded-in on both heald ends, TRANSALLY's popular repair healds ¨C they replace missing or worn out lifting and doup healds ¨C can easily be hooked into the heald carrying rods of the lifting and doup frames.
