Rapier Loom Selvedge Formation Systems
topic
Rapier loom selvedge formation uses leno selvedge heddles that twist edge threads around each inserted weft end to bind the weft at the fabric edge, tucking-in devices that fold the cut weft tail back into the next shed creating a tucked selvedge, or heat-fusing that melts thermoplastic yarn ends to prevent unravelling, with selvedge system selection governing selvedge appearance, stability, and the compatibility of selvedge structure with subsequent cutting, sewing, and finishing operations that determine which selvedge type is appropriate for each fabric end use.
Role
Addresses the fundamental challenge of shuttleless weaving where the weft yarn is cut at the fabric edge after insertion rather than forming the natural loop selvedge of shuttle weaving, requiring active selvedge formation to prevent weft end unravelling that would compromise fabric structural integrity at the edge, with selvedge quality being particularly important for fabrics where the selvedge zone is visible in the finished product or where edge stability is required for automated cutting room processing.
