Set the regulator wheel for the differential feed 41 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. Instead, a smooth seam (A) will be achieved. You can also achieve decorative effects with the differential feed dog. For example the gathering effect when using very light fabrics (B). The following table contains information on the differential feed settings. However, you should always test your setting first on a piece of scrap fabric. Type of fabric / effect Very light fabrics: silk, satin, poplin, taffeta, linings. Normal fabrics: light and medium-heavy cottons, fine cords, thermal-wear. Light knitwear: jerseys, polo fabrics, cut-pile pullovers, tricot, fine knitwear and gathered fabrics. Heavy knitwear: sweatshirt fleece, heavy gathered fabrics, heavy knitwear. Stretch - wavelike effect: medium and light knitwear, jerseys, knitwear, ruffled sleeve and collar edges, skirt hems, dense stitch lengths. Gathering: ruffling light materials and lace, seam allowances for curves, arches on blouses, shirts, skirts, round pockets, flaps, stretching or gentle ruffling of arched sleeves (shoulders), sleeve widths for cuffs or gathered fabrics.

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. Instead, a smooth seam
(
A
) will be achieved.
You can also achieve decorative effects
with the differential feed dog. For example
the gathering effect when using very light
fabrics (
B
).
The following table contains information on the differential feed settings. However, you
should always test your setting first on a piece of scrap fabric.
