2. How It Works: The Sewing Machine

 
 

It's a topological question: when the needle passes the tissue below, it carries the wire in the loop. On the other side there is a system that puts the wire of the second spool (the little one in the machine) in this loop, then the needle rises, taking with it the second wire.
In this way a series of knots are formed along the seam between the spool higher, the big one, and the lower, the small one.
The first practical and widely used sewing machine was invented by Barthélemy Thimonnier, a French tailor, in 1829.
