ABSTRACT:
A method for binding a book wherein the backbone of printed and folded signatures receives a heat activated glue. A short reinforcing cover whose inner surface is also covered with a heat activated glue is applied to the backbone. The outer portions of the short cover are then bonded to the outer pages of the signatures, under sufficient heat and pressure to form a strong bond. A hard cover of suitable size and shape is then glued to the outside of the short cover and the signatures.
