Pin Count
Measured teeth frequency on a gill box bed dictates how parallel raw flax fibres become before sliver formation begins in Chinese textile mills. Mill supervisors record this parameter inside the preparation ledger to verify that mechanical drafting matches the specific denier of the imported stem material. When fine Flemish flax moves through the preparatory frames, excessive pin spacing tears the strand rather than straightening individual filaments.
Fine settings prevent clump accumulation inside the faller bar mechanism, keeping the resulting ribbon uniform for subsequent drafting operations.
Drafting Ratio
Fibre arrangement depends entirely on how closely spaced steel teeth interact with incoming plant material during high speed drafting operations. Jiangsu processing floors rely on exact tooth frequency measurements to prevent tow waste from clogging the delivery rollers during multi stage drawing. Raw bast strands require tight pin intervals to align short and long elements into a coherent ribbon without creating static friction knots.
Excessive gaps between adjacent pins allow loose material to slip past the comb unaligned, producing uneven yarn strength further down the production line.
Grade Variance
Mill operators must distinguish factory acceptance thresholds from the quality limits specified in international linen purchase contracts. Internal technical sheets mandate specific tooth counts for each spinning batch to satisfy the structural demands of high grade warp yarns. Buyer agreements govern ultimate fabric tensile strength, while preparation records control the physical uniformity of the precursor sliver.
Lower pin frequencies suit coarse tow spinning lines destined for heavy canvas production, whereas luxury apparel fabrication demands dense arrangements.
