Differential Feed

Differential feed on an overlock is a two-part feed dog which feeds the fabric at different ratios. The front part of the feed dog feeds more or less fabric under the foot than the rear part of the feed dog does. This feature is useful when sewing knits which have a tendency to stretch and result in waves when sewn on an overlock machine. Differential feed is also good on sheer fabrics which tend to pucker when sewn. Use the 0.5 setting for eliminating puckers. There are two kinds of differential feed: negative and positive.

Standard Feeding

The front and rear feed dogs work as a single unit. The fabric feeds in and out with the same ratio.

Positive Feeding

The looser and stretcher the fabric, the more the front part of the feed dog must feed in and the less the rear part of the feed dog must feed out. Waves are eliminated.

Negative Feeding

The front part of the feed dog feeds in less fabric than the rear part feeds out. The fabric is held taut by the feed dogs. Puckering is eliminated.
