Abstract
A method of manufacturing a soft-cover book of the type having an opening relaxed position in which front and read cover sections may lay flat against a support surface. A collection of pages are perfect bound to form a book block having a spine which is deformable along an arc of 180.degree. without significantly affecting the bond strength of the book block. Preferably, the book block includes a thin flexible capping material across the spine and portions of the opposed sides of the book block. The book block is moved relative to a valved adhesive application station for selective extrusion of adhesive. The adhesive is extruded to form a plurality of adhesive application areas on the spine of the book block, with each application area being spaced apart from adjacent application areas by adhesive-free areas. A soft cover is then brought into contact with the adhesive application areas. Extrusion may be from an elongated outlet which intermittently applied adhesive across the width of the spine. Alternatively, extrusion may be from nozzles which are spaced apart to form spaced apart beads along the length of the spine.
