Abstract: Methods for binding books are provided. In such methods a cover made of a flexible material is provided and a block-book is formed joining a number of signatures and applying glue along the spine of the signatures. The book-block is coupled with the cover, obtaining a bound book. The spine of the bound book is rounded off, in order to give the book an outwardly convex spine. The rounded shape of the spine is maintained for a time interval sufficient to allow drying of the glue within the bound book, and finally the book is trimmed. Books made by such methods are also provided.

At the front slit is provided for introducing sheets or layers to be stapled with the cooperation thereat of said anvil, a staple-carrying magazine, a feeder, a push-load plate, a hammer, and a staple closing plate.
