Profile Reed

Quality Standard

Grade specifications for these tools dictate the degree of permissible variation in blade thickness across the entire width of the loom. Mills verify compliance by measuring the air permeability of the initial cloth samples rather than relying on manual inspection of the reed surface itself. A deviation in the channel width produces thin spots where yarn count drops below the target density.

Fabric grading requires these sensors to remain within a tolerance of five microns to avoid rejection by export inspectors who monitor the consistency of the fabric mass per square meter.

Operational Performance

Maintaining the correct spacing within the reed frame prevents yarn abrasion that occurs when fibers snag on misaligned steel plates during the high-speed oscillation of the shed. Engineers adjust the lateral position of the reed to compensate for thermal expansion in the machine frame during extended shifts of heavy production. Proper positioning of the metal components preserves the structural integrity of flax yarns by minimizing lateral friction against the reed edges.

Uniform distribution of these stresses across the entire warp ensures that the resulting textile maintains a stable width after the finishing process. The mechanical accuracy of this component remains the primary limit on how fast a loom operates without breaking the warp threads.
