ABSTRACT:
A process is provided for binding a plurality of papers arranged together in signatures using an adhesive without requiring the spines of the signatures to be trimmed in order to allow adhesive applied from a single source to contact all of the papers to be bound. A linear array of apertures is cut into each of a plurality of papers. Each paper is folded back on itself to form a signature having two layers of paper with the apertures in each layer at least partially aligned. The signatures are positioned side by side and adhesive is applied concurrently to the spines of all of the signatures, thereby introducing adhesive into the apertures and bonding all of the layers of paper to each other. A backing is contacted with the spines of the signatures to form a cover, thereby providing a bound publication.
