ABSTRACT:
A stack of paper is provided for separating portions produced by a portion control machine. The paper is dispensed from a paper feed system that feeds the bottom-most sheet from the stack along support rails that support opposite edges of the sheet. An integral stiffening strip extends between the opposite side edges of each sheet for stiffening the sheet therebetween and to minimize bowing of the sheet when supported at its opposite side edges. The stiffening strip has an arcuate cross-section, and the stiffening strip includes a rigidifying wax coating that is impregnated in the sheet at least to a greater extent in other areas of the sheet than at the strip. The invention also contemplates a method of fabricating the sheets of paper.
