Automatic Book Stitching Machine

A sewing machine is used to stitch the fabric and other pliable materials together with threads. Sewing machines were invented during the first Industrial Revolution to decrease the quantum of manual sewing done in garment industries.Two of them, a mixture of cams and cranks, operate the feed dog, that little set of teeth that pop up and down just beneath the needle and the presser foot (which holds the material in place); one pushes upward against the material (to grip it) and the other moves it forward by an adjustable amount.
