The My-Lock Serger Series

The MyLock serger series is equipped with a unique differential speed device designed to prevent fabrics from puckering or stretching. Two feed dogs are used - one feeds the appropriate amount of fabric for the setting on the stitch length dial and the other pulls or pushes the fabric according to the ratio set on the differential feed dial. The ratio of differential speed can be selected from a range of 0.7 to 2.0. Both stitch length and differential speed dials and be set at any time, even while sewing.
