Shed Geometry Measurement Techniques
topic
Shed geometry measurement uses optical shed angle gauges positioned at the reed measuring the upper and lower shed line angles in degrees, digital height gauges measuring the physical shed height at the reed and at the back rest, and high-speed camera systems recording the shed profile at multiple crank angle positions to assess shed formation speed and uniformity, with measurement data enabling objective confirmation that shed geometry meets specifications after loom setup rather than relying on empirical assessment.
Role
Provides the objective measurement infrastructure for confirming and documenting shed geometry settings that enables reproducible loom setup across multiple machines and shift crews, with shed geometry measurement being particularly important during process development for new fabric specifications where the optimal geometry settings identified during trials must be accurately documented and transferred to production loom setup to ensure that production looms replicate the geometry that produced acceptable quality during development.
