Abstract
A method and apparatus for permanently binding sheets of paper into a cover inexpensively and quickly is disclosed. Hot melt adhesive dots are placed near a center fold on one inside surface of a cover in alignment with pre-punched holes in paper sheets to be bound. An opposite surface of the cover is folded over and upon the dots and heat is applied causing a top of each dot to adhere to the adjacent cover surface, thus locking the paper sheets to the cover adjacent the center fold.
