both the front and the rear feed dogs. When set at 1, the
feed dogs are moving at the same speed (ratio of 1).
When the differential feed ratio is set at less than 1, the
front feed dogs move slower than the rear feed dogs,
stretching the fabric as it is sewn. This is effective on
lightweight fabric that may pucker. When the differential
feed ratio is set at greater than 1, the front feed dogs
move faster than the back feed dogs, gathering the fabric
as it is sewn. This function assists in removing the rippling
when serging stretch fabrics.
