发明名称 Differential Perforation Pattern for Dispensing Print Media
摘要 A web of print media dispensable as individual sheets along lines of perforation includes a pattern of ties and slits that provide a more predictable resistance to manually separating the sheets from the web. The lines of perforation extend transversely with respect to a longitudinal dimension of the web and cross a longitudinal centerline between two edges of the web. The ties are weaker near the centerline of the web than near either of the two edges sufficient to relatively increase resistance to tearing along the lines of perforation starting near either of the two edges while relatively decreasing resistance to tearing along the same lines of perforation starting near the centerline of the web.
