Woven shoe upper

This invention describes a shoe upper made with a woven fabric. A special "stitching yarn" is integrated directly into the fabric during the weaving process itself, rather than being added afterwards. The claims focus on a method where this stitching yarn runs parallel to the main warp yarns and is woven in simultaneously by moving it sideways through specific gaps in the weaving machine's reed.

Why it matters: The precise mechanical control needed to simultaneously weave a stitching yarn by lateral displacement and through specific reed gaps remains a significant engineering challenge for loom design. No major technological shift in weaving automation has fundamentally simplified this in three years.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedSpecialized weaving loom, custom reed mechanism
