There is provided a dispensing orifice. The edge surfaces of the orifice define a breadth and a width for the orifice. The ratio of the minimum breadth of the orifice to the thickness of a dispensed sheet is preferably about 8:1 to about 18:1. The ratio of the width of a dispensed sheet to the maximum width of the orifice is preferably about 2:1 to about 5:1. In a preferred embodiment, at least one of the sides of the orifice is curved. Moreover, at least one of the sides of the orifice preferably has a plurality of nodules extending a distance into the orifice. Preferably, the ratio of the minimum breadth of the orifice to the distance that the nodules extend into the orifice is about 2:1 to about 8:1. |
