Easy to use overlocker for overlocking rolled hemming and much more.


MyLock 644D


At a glance…

  • Overlocker
  • Sewing speed 1,300 SPM
  • Rolled hem pre-tensioner slide
  • Easy threading lower looper
  • Weight 8Kg


The MyLock 644D includes essential features for simple overlocking. The differential feed system of two feed dogs virtually eliminates puckered edges on woven fabrics and stretched edges on knits. Its unique rolled hem conversion feature eliminates the need to change the needle plate, foot, or tension setting for rolled hemming. Janome has restructured the lower looper guides for easy access. Colour-coded guides are easy to follow for 2, 3, or 4 thread overlocking. All of the features on this machine are specially designed to make this overlocker the easiest to use on the market today.
