Pin Alignment
Steel tooth configuration defines the number of individual needles situated per linear centimetre along a gill bar in a drawing frame. Faller pin density dictates the degree of fiber individualization occurring during the parallelization process of flax sliver. High counts provide finer control over short fibers by preventing uneven drafting or clumped segments.
Operators monitor this parameter to match the mechanical resistance of the pins with the specific weight of the fiber mat passing through the machine.
Alignment Variation
Technical adjustments to the spacing of the pins alter the frictional force applied to the flax. Closer pin spacing reduces the draft force variance and improves the uniformity of the output sliver mass. Wider spacing facilitates the processing of coarser flax varieties where excessive fiber breakage occurs under high resistance.
Settings are recorded on the machine specification sheet to ensure consistency across separate shifts or production runs. Spinning managers adjust these configurations based on the measured sliver fineness and the desired yarn count.
Quality Verification
Inspection of the finished yarn confirms the effectiveness of the chosen density configuration. Laboratory testing of the evenness and imperfection counts reveals whether the drawing stage successfully aligned the internal fibers. Fabric strength data provides the final proof of proper pin settings during the spinning preparation.
Consistent mechanical oversight of these components governs the structural integrity of the final linen textile.
