A bookbinding structure and method. The bookbinding structure is used to bind pages together in existing, commercially available binding machines. The bookbinding structure has a heat activated adhesive matrix for binding the pages. To attach a wrap-around book cover once the pages have been bound with the bookbinding structure, an adhesive on the outer surface of the bookbinding structure may be exposed by removing a release liner covering the adhesive. The book cover may then be adhered to the exposed adhesive either by a heat method or by applying pressure over the adhesive, depending on the particular type of adhesive of the bookbinding structure. The book cover may be printed with information and/or graphics prior to being wrapped around the pages of the book.

Bookbinding structure and method

A bookbinding system and method of binding books including a cover/spine assembly having a relatively rigid cover section with a length and width at least as great as that of the stack of sheets to be bound and a spine section having a width greater than the height of the stack. The cover/spine assembly and the spine section are secured together along the length of the cover section so that the spine section can be folded along a first edge with respect to the cover/spine assembly. A heat activated matrix is disposed on the spine section including a central adhesive band and an outer band disposed between the central adhesive band and a second edge of the spine section. Binding is carried out by placing the stack over the cover section and folding the spine section over the edge of the stack. Preferably a second relatively rigid cover section is placed on top of the stack so that the outer adhesive band on the spine section will extend over second cover section. The central adhesive band is a low viscosity adhesive which, when activated, bonds the sheets of the stack to the spine section to form the spine of the bound book. The outer adhesive band, when activated, bonds the second cover to the spine section thereby forming a hardcover book having the feel and appearance of a book bound using conventional techniques.
