Record a post-sewing twist investigation Keep tape orientation, assembly geometry and load path connected. Symptom Record: Twist direction, location, load state, timing and affected quantity Project detail: ____________________ Confirm: Video from a fixed view Loose-tape control Record: Relaxed flatness, skew, edge shape, face and roll direction Project detail: ____________________ Confirm: Compare unsewn labeled strip Cut-piece orientation Record: Face, left/right edge, cut direction, mirrored pair and bundle order Project detail: ____________________ Confirm: Match marks to cutting plan Seam geometry Record: Overlap, stitch position, layer alignment, feed direction and puckering Project detail: ____________________ Confirm: Measure both faces Hardware path Record: Model, entry face, wraps, anchor alignment and swivel freedom Project detail: ____________________ Confirm: Compare approved routed assembly Load observation Record: Anchor points, direction, sequence and where rotation begins Project detail: ____________________ Confirm: Apply repeatable product-use path Acceptance should use the product’s intended worn or loaded orientation. Keep controls before dismantling so correction does not erase the evidence. Sinicwebbing — https://www.sinicwebbing.com
