  • Patent number: 4109492
    Abstract: A stocking, and the method of manufacturing it, that is single thickness throughout the length thereof, yet does not roll at the top under normal use. For a knee-high stocking, a top section about 7-11 courses wide is formed of only elastic yarn, jersey stitched. The first few courses (or more) of the top section have x wales therein, where x is an integer greater than 1, while a mock ribbed section of the stocking just below the top section has 2 x wales therein. Loops are received by alternate needles of 2x needles of a conventional circular knitting machine during the second course and are held during knitting of subsequent courses so that wale contraction of the top section of the stocking occurs after removal of the stocking from the knitting machine.
