Reed Marks and Starting Marks Read Back to the Loom
Greige reed marks and starting marks map directly to reed wire spacing and loom stoppage dynamics, requiring electronic let-off adjustment to eliminate defects.
Fabric Inspection Frame
Optical Assessment
Vertical rollers hold a bolt of linen under tension as light passes through the textile to reveal defects in the weave or surface. A fabric inspection frame provides the physical platform required for graders to mark irregularities while the cloth moves at a constant speed. This mechanical assembly keeps the material flat against a backlighting panel to improve the visibility of broken ends or foreign matter.
Operators adjust the scroll rate to accommodate different weights of flax yarns, ensuring that each meter passes the scrutiny of the quality control team. Consistency in light intensity remains the requirement for accurate grading across different shifts within the finishing plant.
Mechanical Operation
Tension bars and drive motors control the path of the textile to prevent stretching or creasing that might mask a fault. Sensors detect the edges of the roll to keep the fabric aligned, preventing shifting that would otherwise damage the selvedge during the process. Guards protect the drive components while allowing access for the removal of waste threads caught in the guides.
Power consumption depends on the width of the frame and the speed of the motor required for high output finishing lines. Calibration of the drive unit happens monthly to prevent uneven feeding that creates visual distortions in the cloth.
Evaluation Protocol
Acceptance criteria for individual defects rely upon the count of flaws per hundred square meters of product recorded in the final inspection report. A fibre grade focuses on the raw flax quality before spinning, whereas the cloth grade evaluates the finished textile through the prism of the mill standard or the buyer specification. Sellers provide these records to satisfy international standards of transparency regarding the condition of the linen before export.
Quality managers compare the defect density of the current run against the historical baseline established by the factory to identify trends in loom performance. Corrective action protocols trigger if the frequency of faults exceeds the threshold defined by the contract between the mill and the buyer. This apparatus functions as the definitive reference point for all claims of material irregularity found after shipment.
