Abstract:
1. A web product, comprising: a web formed of paper or a like material having one or more plies and having a first side, a second side, a machine direction, a cross direction orthogonal and coplanar thereto, and a Z-direction orthogonal to both the machine and cross directions; a plurality of repeating lines of weakness forming a plurality of separable individual sheets comprising a wound or rolled product, each of said plurality of repeating lines being spaced from each other in the machine direction, each of said repeating lines of weakness comprising a plurality of individual overstrained fibers extending in the Z-direction and substantially from the first to the second side of the web, each of the plurality of individual overstrained fibers being selectively located relative to an adjacent overstrained fiber of the plurality of individual perforations to collectively define a selected perforation design extending from said first side to said second side and having machine direction and cross direction components; and, wherein the web is formed of a material strong enough to form the wound or rolled product having the repeating lines of weakness but weak enough to separate a selected separable sheet from the remainder of the wound or rolled product by tearing along one of the repeating lines of weakness defining the separable sheet.
