ABSTRACT:
A binding system including a method for binding sheets in which a stack of the sheets is shingled to disclose narrow side surface portions along their spine edges, a uniform layer of pressure sensitive adhesive 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 re-form the pressure sensitive adhesive along the spines of the sheets, and a flexible backing is adhered over the re-formed adhesive along the spine edges and at the side surfaces of the sheets to retain the spine edges of the sheets in that alignment. 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.
