NARROW AND ROLLED HEMMING
By changing the needle plate to “Rolled Hem Needle Plate” and using right needle only, the machine trims fabric,
folds back the edge and sews a narrow hem (overedge). The width of the narrow overedge is 1.5 mm (about
1/16") and is used for overedging light and medium weight fabrics.
Two variations of the rolled overedge hem can be sewn with this machine by changing the thread tension.
Both methods are used with light and medium weight fabrics.
Method B gives a softer finish by pulling the interlocking threads to the wrong side.
