ABSTRACT:
A method for binding a stack of fan folded sheets including manually disposing the stack of sheets with spine edges of the sheets generally aligned in a plane generally at a right angle to the side surfaces of the sheets in the stack; manually positioning a thick layer of pressure sensitive adhesive already adhered to a generally planar portion of a highly flexible backing having low resiliency over the spine edges; and manually pressing the side of the backing against the spine edge of the sheets to cause conformation of the backing and adhesion of the layer of pressure sensitive adhesive to the spine edges of the sheets, which is most easily done by manually pressing the spine edges of the sheets toward an edge of a structure such as a table or desk with the edge disposed transverse of the spine edges of the sheets along the surface of the backing opposite the layer of pressure sensitive adhesive while moving the spine edges longitudinally to bring the majority of the side of the backing opposite the layer of pressure sensitive adhesive progressively into engagement with the edge.
