Machine to work a relatively rigid material, which comprises a plurality of operating units (20a, 20b) to work the relatively rigid material.

The invention relates to an applicator unit, a tire building device and a method for applying a strip to a drum, wherein the applicator unit comprises an applicator roller and a cutter, wherein the applicator roller comprises a roller body that is rotatable about a roller axis for applying the strip to the drum in an application direction perpendicular to said roller axis, wherein the applicator roller and the cutter are configured to cooperate for cutting the strip on the applicator roller along a helical cutting path about the roller axis.

A roll of sanitary tissue product comprising a shaped line of weakness, where the roll of sanitary tissue product may exhibit a roll compressibility of from about 4% to about 10% and a LWP Factor of greater than about 8.

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 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.

A web of toilet tissue that includes a shaped line of weakness, wherein toilet tissue exhibits a LWP Factor of greater than about 7.

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 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 rotary cutting device comprising an anvil and roll having at least one knife affixed thereon, the roll being rotatably mounted to the machine by bearings disposed on opposing ends of the roll and supported by bearing mounts connected to the machine frame. A thermal isolating mounting arrangement orients the bearing mounts so that thermal growth occurs along an axis generally perpendicular to a plane in which the knife and anvil interface. A thermal isolator may also be disposed between the bearing mounts and the machine frame to further inhibit heat transfer into the frame and the resultant effect on knife position.
