Abstract

See full text

The paperback book of this invention has a book block with a plurality of sheets joined together at their spine edges. The book also has a stiff cover. A flattened woven tubular ribbon with tabs which is glued to the cover and the book block is glued to the ribbon. The tubular ribbon has tabs which extend continuously along the length of the ribbon and are 180 degrees apart on the outside circumference of the ribbon. The tabs thus divide the outside circumference of the ribbon into two regions. A first outside region of the ribbon is fastened by an adhesive to the inner spine portion of the cover and the surfaces of the tabs which extend from the first region are fastened by the adhesive to the inside surface of the cover adjacent to inner spine portion of the cover thus reinforcing the attachment of the cover to the spine. Adhesive also attaches the back of the book block at a second section of the outside circumference opposite the first section of the tubular ribbon. The first and second sections of the tabbed tubular ribbon are joined only where they join the tabs. Hence the book has a book block which is fully attached to the cover yet which is fully free to flex.
