    • 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.
    • 设置有分配孔。 孔口的边缘表面限定孔口的宽度和宽度。 孔的最小宽度与分配片的厚度之比优选为约8:1至约18:1。 分配片材的宽度与孔口的最大宽度的比率优选为约2:1至约5:1。 在优选实施例中,孔口的至少一个侧面是弯曲的。 此外,孔口的至少一个侧面优选地具有多个向孔口延伸一定距离的结节。 优选地,孔的最小宽度与结节延伸到孔中的距离的比率为约2:1至约8:1。
