Janome MyLock 634D Serger

The Janome MyLock 634D with electronic control is the most advanced MyLock serger. It has 2 needles and 2, 3 or 4 thread overlock stitching. The differential feed ratio is adjustable from .05 to 2.25 and provides increased control for all types of fabrics and special effects.

Threading is simple due to the color-coded thread guides and a self-threading lower looper. Simply lay the thread into the guide, flip a switch, and the lower looper is threaded.

The guide is automatically returned to its normal position when you turn the balance wheel. And when you lift the presser foot for rethreading, the thread tensions are automatically released so you can draw the thread smoothly.

This self-threading serger also lets you quickly switch to rolled hemming without changing the needle plate. A lower looper pre-tension stitch eliminates the need to change tension for rolled hems.
