Abstract
A binding system including a method for binding connected fan folded sheets in which a stack of the sheets is shingled to disclose narrow side surface portions along their spine edges, a layer of pressure sensitive adhesive on a highly flexible backing is adhered to those spine edges and narrow side surface portion after which the spine edges are moved into alignment at a right angle to the side surfaces of the sheets to cause the backing and layer of pressure sensitive adhesive to pleat around the spines of the sheets. The system also includes a novel cover structure which facilitates the method and includes cover plates, the pressure sensitive adhesive and the backing; and a novel device for holding and positioning the sheets during binding.
