<p>An article of manufacture (10) includes a first pad of sheets (11) with a plurality of layers where the first pad of sheets perimeter is defined by a first edge (12), a second edge, a third edge (14) and a fourth edge. The article of manufacture (10) includes a second pad of sheets (16) with a plurality of layers where the second pad sheets perimeter is defined by a fifth edge (17), a sixth edge, a seventh edge (19) and an eighth edge. The first and second pad of sheets (11 and 16) are releasably bonded together at the first (12) and fifth (17) edge by a first adhesive (21). The first adhesive (21) forms a hinge structure allowing each of the pad of sheets to rotate about an axis. The second pad of sheets (16) are releasably bonded together at a portion of the bottom side of each sheet located at the fifth edge (17) by a second adhesive (22). The remaining portion of the bottom side of each said sheets (16) of the second pad is free of the second adhesive (22). Finally, the second adhesive (22) has a peel strength less than the first adhesive (21).</p> |
