Perfect binding, characterized essentially by the fact of being constituted by a rectangular laminar development of flexible material, such as card stock or similar, provided with transverse creasing lines and bellows lines delimiting a spine; and in that the creasing lines and the sheet edges parallel thereto limit the surfaces which, when folded down and glued to the adjacent adjacent surfaces of the sheet, provide hard cover covers, capable of being bent by the aforesaid bellows lines.
