Abstract
A method of providing an improved mechanical bond when fastening a plurality of paper sheets together. The body of sheet material is punched or cut through to form a flap. The flap is then folded over upon the body of sheets, and the flap and body of sheets are simultaneously crimped. A superior mechanical bond is formed, because three separate bonds are made; the body of sheets are fastened together, the layers of the flap are fastened together, and the body of sheets is fastened to the flap.
