ABSTRACT:
A stubless unit set of multiple plies of the type including at least superimposed top, intermediate and bottom plies is made by removably interconnecting the top and bottom plies together and by removably interconnecting the intermediate and bottom plies together. The top and bottom plies are interconnected by providing a fold flap along an edge of the top ply, applying detachable adhesive to the flap, folding the flap to underlie the bottom ply and contacting the bottom ply with the adhesive, and the intermediate and bottom plies are interconnected by providing at least one hole in the bottom ply and extending a portion of the adhesive through the hole so as to contact the intermediate ply. Each of the plies is devoid of any tear lines which may form a stub.
