There are various ways to knit a cuff on the sock machine. The one that’s most familiar to beginners is the hang hem what requires no ribber and it is my preferred method. Another method requires the ribber and uses the in/out switches on the ribber cam to take the ribber out of use for a few rows and then put back in again. Both of these methods are quite common on commercial socks.
There is a more time consuming process called the e-wrap that provide better looking edge, but this method has been a mystery to me because the instructions in the original AutoKnitter manual is cryptic. Thankfully, a step-by-step instruction was posted on Ravelry in the Circular Sock Machine Group and I promised myself that I will post photos if I can make it work.
First, take all the needles out of work, follow the direction of the yarn carrier (counter clockwise), and wrap around each needle starting from the right side. Even though it is called a e-wrap, it is more like an &-wrap. Think of writtting an &, start from the bottom right, move up, wrap around the needle, and move down to the left.
Push the needles and the wrap down and crank (slowly).

Insert ribber and switch cylinder needles with ribber needles.
Crank sock as usual and remove completed sock from machine. Shown here is the right side of the cuff, prior to removing the waste yarn.
Shown here is the wrong side. It’s much easier to remove the waste yarn from the wrong side. Find the purl bump and pull. Make sure you’re cutting the waste yarn, not the working yarn.
Voila! The selvedge of an e-wrap. Much neater than the in/out ribber needles and not restricted to 1×1 ribbing. Happy cranking!
