Abstract:
1. A method of conditioning a sheet of paper for subsequent binding, said method comprising: splitting the edge of the sheet, with said splitting resulting in an expansion of a thickness of the sheet, with the sheet edge being split for at least 25 percent of the length of the sheet; and subsequent to the splitting, compressing the edge of the sheet so that a ratio of a sheet edge thickness after compressing to the thickness of the sheet edge prior to the cutting is less than 1.3 and wherein the splitting includes passing the sheet over a first rotating roller while applying a cutting member to the sheet edge, with said first roller being positioned relative to the sheet edge such that one of the sheet split ends is disposed intermediate the first roller and a portion of the cutting member so that said first roller provides support to the sheet edge during the splitting.
