ABSTRACT An improved book which is bound ready to be covered or cased consists of a pack of signatures plus front and back end sheets, with the signatures closed along the spine and a multiplicity of closely spaced, wide open notches penetrating the entire spine and all the closed sides of sheets in the pack to greatly en- large the area of the spine to which adhesive may be applied. A wrap-around coating of adhesive covers the surfaces of the notches, the spine between the notches, and the faces of the end sheets between the notches. The book is made in high speech commercial per- fect binding equipment which is modified by substituting a notch cutter for the roughing cutter, adding pinch rolls downstream from the notch cutter, and adding ap- paratus to apply metered quantities of hot melt adhesive in a first coat consisting of thin strips along the notched faces of the end sheets and extending into the notches, so that when a second conventional. coat of hot melt adhesive is applied to the notched spine by a roller, the second coat may amalgamate with the first coat in the notches.
