This invention describes how to make a shoe upper using a knitting machine. The machine creates the entire upper, including the heel and other parts like a tongue or even a sole, as one seamless piece of fabric. This means there's no need to cut or sew different pieces together after the knitting is done, resulting in a complete, dimensionally shaped upper ready for assembly to a sole.
Why it matters: Filed before advanced knitting design software became more accessible. Complex 3D shapes are now easier to program and simulate.
