Invention of the stapler

The traditional method of binding books involves sewing the pages together using “sticking codes”. This is a rather complex process; it is simple for skilled binders, but may be difficult to achieve with a machine. Therefore, binders who want to increase their work efficiency—especially when producing small brochures and magazines that typically require quick processing—try to find ways to use short bends.wired wireMethod for binding.

1869USA Massachusetts BostonThomas Brigs invented a machine capable of performing this task. He founded the “Boston Wire Binding Machine Company” to manufacture and sell such machines. His machine crushes the wire, bends it into an U-shape, uses it to sew the pages together, and then bends it again to properly secure the book.

Briggs' original stapler was quite complex due to the many steps required. Therefore, in 1894, he adopted a manufacturing process in which iron wires were first bent and cut, forming a series of “U” shaped staples. These staples could be inserted into a much simpler machine that could embed them properly.paperGo ahead. This machine is the prototype of the bookbinding machines used in offices and homes today.

In the early days, U-shaped staples were wrapped in paper or placed individually in staplers. The use of staplers became increasingly common in the 1920s, and by then, U-shaped staples could already be glued together into long strips for market release.
