Selvedge Thread Preparation and Leno Selvedge Systems
topic
Selvedge thread preparation in shuttleless weaving draws additional edge warp ends through leno heddles or temple selvedge devices positioned at each fabric edge, with leno selvedge systems twisting two edge ends around each inserted weft pick to bind the cut weft end and prevent selvedge fraying that would occur if the weft end is simply cut flush with the last warp end in the main fabric.
Role
Produces a stable, fray-resistant fabric selvedge on shuttleless woven fabrics where the weft yarn is not carried continuously in a shuttle across the full machine width, with leno twist selvedge formation being the dominant method for producing the woven selvedge integrity required for fabric handling in finishing and garment making operations without the loss of weft ends from the cut fabric edge.
