The traditional book binding method is to sew the pages together according to the label. This is a rather complicated process, and many bookbinding workers are trying to find a way to bind with a small piece of curved wire.
1869, Thomas Briggs from Massachusetts, USA, invented a machine that could do this job. His machine breaks the wire and bends it into a U-shape, then uses it to nail through the pages, and finally bends it to fix the book correctly.
Because of the complicated operation steps, Briggs improved the manufacturing process. First, the iron wire is broken and bent to make a series of U-shaped staples. These nails are put into a simple machine and can be embedded in paper. This machine is the prototype of the stapler that is widely used now.
