All knitting machines that exist today work by having a rack of hooks, which hold all the stitches on each row. This puts an upper limit on the size of the product, and increases and decreases in stitches (such as those required to make a hat or stuffed animal) for non-industrial knitting machines must be done manually.

We have invented a novel mechanism for knitting. Our method mimics the way a human knits, by holding the stitches on a cord or rod, and only using machinery to knit one stitch at a time, allowing for increases (stitches to be knit twice), decreases (adjacent stitches to be knit together), and scalability (the number of stitches is only limited by the length of the cord holding them).
