发明名称 Truncated corner paper toweling and method
摘要 A paper towel, a roll of paper toweling, and a method of making the same that produces a paper towel sheet having perforated corners of tear-off construction that each leaves a truncated corner when torn off. Each such truncated corner preferably is radiused or rounded. The roll includes an elongate web of material that has a plurality of pairs of perforations that extend along a substantially straight line from one side edge to its other side edge defining a plurality of pairs of paper towel sheets with squared-off sheet corners. Each squared-off sheet corner is bounded by a plurality of pair of perforations that extend along a line that truncates the corner and produces a tear-off corner that leaves a truncated corner when torn off. In a preferred method, each dividing perforation line is formed substantially simultaneously with a pair of perforated corners of one adjoining sheet and a pair of perforated corners of the other adjoining sheet.
