Feed dog:

•Moves fabric under the presser foot as stitches are formed.
•This consists of a set of teeth fitted below the needle plate. It helps to move the cloth forward while sewing.

Bobbin Winder:

•Allows you to fill a bobbin automatically
•A simple mechanism used for winding thread on the bobbin.

Thread Take-up lever:

Controls the thread as it flows through the needle.
It is a lever fitted to the body of the arm. Its up and down motion feeds the thread to the needle and tightens the loop formed by the shuttle.

Tensioner:

The two concave discs put together with the convex sides facing each other. The thread passes between the two. The tension of the thread is adjusted by a spring and nut which increases or decreases pressure

Reverse lever:

The reverse lever allows you to stitch in reverse. We use reverse to make our stitches secure at the beginning and end of seams.
