Differential feed The differential feed consists of two feed dogs (A + B), one behind the other, which feed the fabric.

The standard setting is 10, where the movement of the front [...]

Set the regulator wheel for the differential feed 49 to 2.0. Here the front feed dog feeds twice as fast as the rear feed dog. This means that the front feed dog feeds twice as much fabric as the rear feed dog, causing the material to gather. Here you will avoid stretching in the seam when working with knitwear, such as jerseys or gathered fabrics.[...]
