Sley and Reed Count Specification
topic
Reed count or sley specifies the number of dents per centimetre or per inch in the reed, with warp ends threaded at typically 1 to 3 ends per dent according to the required warp sett, with reed count selection requiring the combination of dents per unit length and ends per dent to achieve the exact warp thread spacing specified, and with reed wire profile and spacing tolerance being critical for warp end guidance and beat-up uniformity that requires consistent dent spacing within plus or minus 0.05 millimetres across the full reed width.
Role
Specifies the reed construction parameter that determines warp end spacing and beat-up uniformity, with reed count selection being one of the fundamental loom setup decisions that directly establishes the warp thread spacing in the fabric, and with reed quality maintenance including inspection for damaged or bent dents being essential for fabric quality because locally uneven dent spacing creates periodic warp crowding defects visible as vertical streaks in the finished fabric.
