A web of sanitary tissue of the present disclosure may comprise a shaped line of weakness, wherein the toilet tissue exhibits a Line of Weakness Performance Factor (LWP Factor) of from about 7 to about 30, and a Full Sheet Average Trapezoidal Tear Strength of between about 8 g and about 20 g according to the Full Sheet Average Trapezoidal Tear Force Test Method.

A cutting die for rotary die-cutting of a label laminates is described herein. The cutting tools of the die include at least one of the following cutting edge parameters: effective height, shape and bevel angle arranged to be different in a first direction when compared to a second direction of the cutting die. The use of the cutting die, a method for designing a cutting die and a method for die-cutting a label laminate are also described.

A roll of sanitary tissue product that includes a shaped line of weakness, wherein the roll of sanitary tissue product exhibits a roll compressibility of from about 2% to about 10%, and the sanitary tissue product has a Full Sheet Average Trapezoidal Tear Strength of about 8 g to about 20 g, as measured by the Full Sheet Average Trapezoidal Tear Force Method.

A roll of sanitary tissue product that includes a shaped line of weakness, wherein the roll of sanitary tissue product exhibits a roll compressibility of from about 2% to about 10%, and a Full Sheet Tensile Strength of between about 400 g and about 850 g, as measured by the Full Sheet Tensile Strength Test Method.

The present disclosure relates to adjusting and maintaining a position of a cutting surface used to create lines of weakness for rolled products. A perforating apparatus includes a housing rotatably supported by a frame, wherein the housing is adapted to rotate about a first axis. A support member including a first cutting surface is rotatably supported by the housing, wherein the support member is adapted to rotate about a second axis offset from the first axis. A roll including a second cutting surface is positioned adjacent the support member, wherein the roll is adapted to rotate about a third axis. The second cutting surface is adapted to contact the first cutting surface as the roll rotates about the third axis. The perforating apparatus is configured such that the functions of adjusting the position of the first cutting surface and holding the first cutting surface in a fixed position are separate.

A web of toilet tissue that includes a shaped line of weakness, wherein the toilet tissue exhibits a LWP Factor of greater than about 7, and an average Free Fiber End value of greater than about 1.5.

A hot knife apparatus for cutting tubular webbing. The hot knife includes an anvil having a surface for cutting a tubular webbing, and a hot knife positioned above the anvil adapted to cut the tubular webbing on the surface of the anvil. The anvil has a first slope on an input side of the apparatus and a second slope on an output side of the apparatus. A pair of spreaders is positioned adjacent to the first slope and the second slope for applying tension to the tubular webbing.

A method for cutting a metallic film is disclosed. The method includes: feeding the metallic film between a scoring blade and an anvil at a first speed; feeding a first protective film between the metallic film and the scoring blade; feeding a second protective film between the metallic film and the anvil; moving the scoring blade toward the anvil for applying a pressure onto the first protective film, the metallic film, and the second protective film disposed between the scoring blade and the anvil for making a score along a width of the protective film; and pulling the metallic film having passed between the scoring blade and the anvil at a second speed. The second speed being greater than the first speed. A difference between the first and second speeds causes the metallic film to cut at the score. A system for cutting a metallic film is also disclosed.

An assembly for chopping glass fibers including a cutter wheel having a plurality of radially extending blades and a cot wheel adjacent the cutter wheel. The cot wheel including an inner hub, an elastomeric ring mounted onto the inner hub for rotation therewith; and a retaining device fixably attached to the hub and engaging the elastomeric ring to resist separation of the elastomeric ring from the hub during rotation of the cot wheel.
