Abstract of the Disclosure A unit set or assembly of multiple plies includes superimposed top, intermediate and bottom plies as well as a cover ply disposed over the top ply. A flap is removably connected to this cover ply along the line of weakening and underlies the bottom ply. First and second axially aligned holes of dif- ferent sizes are respectively provided in the bottom and intermediate plies, the size of the bottom ply holes being less than the size of the intermediate ply holes. Adhesive is provided on the flap for securing the top ply thereto, such adhesive extending through the intermediate ply holes. The size differ- ence between the axially aligned holes defines portions of the bottom ply which serve to mask the intermediate ply holes so as to confine the cross-sectional size of the adhesive, which extends therethrough, to the smaller size of the bottom ply holes. Accordingly, the cover ply may be removed from the set while leaving the remaining plies intact, and separation of the top and bottom plies breaks the adhesive and frees the intermediate ply. Thus, a multiply set is provided without the need for a removable stub thereby resulting in paper sav- ings and avoiding the need for stub handling and disposal.
