Levers & Mechanisms When Stitches are Formed on the Sewing Machine

Whenever we use a sewing machine we are using a variety of different levers and mechanisms. In the video the bit we can’t see is the motor transferring circular motion (via the wheel turning at the side of the machine) to reciprocating motion (the needle going up and down) whilst the fabric moves through the machine (using linear motion). The bobbin case area is turning backwards and forwards at the same time which is an oscillating motion. 

This video on the history of the sewing machine has more information on how stitches are formed as well as showing how levers and mechanisms work in a sewing machine. 

Although the video below is in German the images on their own give a fairly clear idea of how a sewing machine works.
