Janome MyLock 644D Overlocker
The Janome MyLock 644D Overlocker makes sewing easy! Incorporating the differential feed system of two feed dogs, puckered edges on woven fabrics and stretched edges on knits are virtually eliminated. The rolled hem conversion feature eliminates the need to change the needle plate, foot, or tension setting for rolled hemming. Restructured lower looper guides allow easy access. The included threading card and colour-coded guides are easy to follow for 2, 3, or 4 thread overlocking. The 644D has a solid metal base plate to deliver great stability when sewing.
