Selvedge Thread Preparation and Leno Systems
topic
Selvedge thread preparation for shuttleless looms uses separate small selvedge packages of the same or stronger yarn threaded through dedicated leno twist heddles or tucking-in mechanisms at the fabric edges, with leno selvedge systems twisting edge threads around the weft end inserted across the full width to bind the weft at the selvedge that shuttle looms form automatically by weft pirn end turn-back, requiring additional threading and tension control for selvedge-forming yarns beyond the main warp threading operation.
Role
Provides the selvedge integrity required for shuttleless woven fabrics where the weft yarn cut at the fabric edge after insertion does not form a natural loop selvedge as shuttle weaving creates, with proper selvedge thread preparation and threading being essential for producing the clean, stable fabric edge that finishing operations, customer specifications, and automated cutting-room processing require from all commercial woven fabrics.
