    (54) Binding system


    (57) A binding system including a method for binding sheets (18) in which a stack (22) of the sheets (18) is shingled to disclose narrow side surface portions (24) along their spine edges (19), a uniform layer (26) of pressure sensitive adhesive is adhered to those spine edges (19) and narrow side surface portions (24) after which the spine edges (19) are moved into alignment at a right angle to the side surfaces of the sheets (18) to re-form the pressure sensitive adhesive along the spines (19) of the sheets (18), and a flexible backing (28) is adhered over the re-formed adhesive along the spine edges (19) and at the side surfaces of the sheets (18) to retain the spine edges (19) of the sheets (18) in that alignment. The system also includes a novel cover assembly (30) which facilitates the method and includes cover plates (31, 45), the layer 26 of pressure sensitive adhesive and the backing (28); and a novel device (14) for holding and positioning the sheets (18) during binding.
