Abstract
This sock is provided with an outwardly rolled decorative upper edge (13) which is integrally knit with the sock to provide the appearance of a simulated overedge stitch and is formed on a conventional type of circular hosiery knitting machine without requiring extensive modification. The formation of the simulated shell overedge stitch on the knitting machine eliminates the separate step of sewing on an overedge shell stitch, as has been the prior practice. The decorative upper edge is formed of a substantially inelastic yarn (I), a stretchable yarn (S), and an elastic yarn (E). These three yarns are knit in plated relationship in stitch loops in spaced apart wales (W-1 and W-5) of a plurality of successive courses (C-5 through C-8) with the spaced wales being spaced apart by at least two intervening wales (W-2, W-3 and W-4). The inelastic yarn (I) and the elastic yarn (E) float across the intervening wales while the stretchable yarn (S) forms tucks extending across the intervening wales. The floats of the inelastic yarn (I) form a series of relatively large outwardly protruding loops (L) which alternate with a series of smaller outwardly protruding loops (L') to simulate an overe…
