Fibre Distribution
Flax tow becomes a secondary product after the primary long line fibre passes through the heavy machines of the hackling process. Hackling comb tow allocation determines how much short fibre collects in the base of each individual comb or catch-tray before automatic clearing cycles engage. Quality control teams use this metric to gauge machine efficiency by comparing the actual weight of gathered tow against the expected yield for a given line speed and setting.
Production reports track these figures to identify mechanical wear on comb pins or gaps in the feed mechanism.
Process Efficiency
Precise regulation of the drop rate prevents fibre entanglement within the dense metal teeth. Overloading the combs forces long fibres into the waste stream while underloading leaves excessive air gaps that reduce throughput consistency. Technicians calibrate the discharge sensors based on the moisture content of the incoming raw flax because drier material packs differently than humidified stock.
Stable environments allow the system to maintain a steady ratio of tow to long fibre throughout the entire shift.
Machine Integrity
Variations in the gathered weight signify structural fatigue in the rotary clearing brushes or misaligned comb bars that disrupt the stripping action. Consistent deviations from the target allocation force a full inspection of the pinning density and the timing of the mechanical knock-off pins. Properly set equipment keeps the fibre flow uniform and minimizes the down time required for manual intervention.
High performance hardware relies on the correct relationship between the comb penetration depth and the density of the hackled material.
