ABSTRACT:
A method for forming a unitary assembly of a plurality of unitary, multi-panel, folded leaflets. Opposed end edges of the leaflets are positioned adjacent one another. A first continuous adhesive coating is applied, preferably by spraying, onto first end edges of the leaflets and portions of the leaflets adjacent the first end edges and a second continuous adhesive coating is applied, also preferably by spraying, onto second end edges and adjacent portions of the leaflets. In a method for forming a plurality of the assemblies of leaflets, a divider bar is inserted between selected leaflets prior to application of the adhesive coatings such that at least two leaflets are disposed on either side of the bar. Upon removal of the divider bar, portions of the adhesive coatings are removed from between the selected leaflets. Also disclosed are an assembly of booklets and a method for forming the same.
