Abstract:
A bookbinding structure for binding a stack of sheets, with the stack of sheets having a thickness, a width and a length, said structure comprising:an elongated substrate having a length that generally corresponds to the length of the stack and a width greater than the thickness of the stack; a first heat activated adhesive matrix disposed on a first surface of the substrate; a second pressure activated adhesive matrix disposed on a second surface of the substrate, opposite the first surface, with the pressure activated adhesive matrix including a first segment that extends substantially along the full length of the substrate and a second segment that extends substantially along the full length of the substrate; a first release liner disposed over the first segment of the pressure activated adhesive matrix; and a second release liner, separate from the first release liner, disposed over the second segment of the pressure activated adhesive matrix.
