Selvedge Beat-Up and Edge Uniformity
topic
Selvedge beat-up quality requires the weft turns at the selvedge to be consistently compacted to the same pick density as the body of the fabric, with selvedge weft loops on shuttle looms and selvedge leno or tucking systems on shuttleless looms creating locally different weave structures at the fabric edge that have different beat-up resistance requiring reed modification or selvedge yarn tension adjustment to achieve edge density matching the body, with tight selvedges causing draw-in and loose selvedges creating irregular edges.
Role
Manages the specific challenge of selvedge zone beat-up consistency that differs from body fabric beat-up from the different weave structure and yarn configuration at the fabric edge, with selvedge quality being particularly important for fabrics where the selvedge zone is visible or structurally functional and where the edge regularity affects the efficiency of automatic cutting room processing that uses selvedge detection for fabric alignment.
