A perforating apparatus and method includes a longitudinal cylinder axis about which a cylinder rotates. At least one shaped anvil bead is disposed on the cylinder. The cylinder including an anvil block and an anvil bead form a cavity. The cavity may be used to control the debris produced during the perforating process. A blade is disposed on a support to cooperate in contacting relationship with the anvil bead. A web is perforated as the web passes between the rotating cylinder and the support and the blade operatively engages with the anvil bead. The debris may be controlled by being drawn into the cavity prior to the point where the blade engages the anvil and, subsequently, being expelled after the point where the blade engages the anvil bead.

A cutting equipment trims strips of webs in movement by means of a stationary trimming blade and a rotating cylinder with a mobile trimming blade during transversal cuts and separation of basic sheets. The rotating cylinder includes a sector with suction openings connected to a vacuum source, which retains the strips by suction and drags the strips up to a collector of the trimmed strips. The cutting equipment cuts and separates transversal strips of two webs overlapped in adherence jointly to the cutting of the basic sheets. To this end, a perforating device perforates a row of holes on the first web adjacent to an edge of the sheets: a first web is positioned with the row of holes in front of the suction openings, while the strip of the second web is retained and dragged by suction through the holes of the first web up to the collector of the trimmed strips.

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.

A roll cutting device for a web processing machine having a cutter roll with only one knife affixed thereto, the cutter roll being rotatably mounted to the machine and configured to perforate or cut the web once per revolution of the cutter roll, and a stress balancing member mounted to the cutter roll in diametric opposition to the knife, the knife and the stress balancing member being connected to the cutter roll by similar connection means so that mechanical stresses caused by connection of the knife and the stress balancing member are balanced and the cutter roll rotates without stress-induced eccentricity.

A roll of sanitary tissue product comprising a shaped line of weakness, where the roll of sanitary tissue product may exhibit a Full Sheet Average Trapezoidal Tear Strength of between about 8 g and about 20 g, as measured by the Full Sheet Average Trapezoidal Tear Force Method, and wherein the sanitary tissue product may exhibit a Geometric Mean Peak Elongation of greater than about 15%, as measured according to the Dry Tensile Strength Test Method.

A paper feeding device in an embodiment includes a roll-paper storing unit, a curl rectifying unit, and a cutting unit. The roll-paper storing unit is capable of storing roll paper. The curl rectifying unit is disposed on a downstream side of the roll-paper storing unit in a conveying direction of a sheet let out from the roll paper and rectifies a curl of the sheet. The cutting unit is disposed on the downstream side of the curl rectifying unit in the conveying direction and cuts the sheet.

There is described a device with quick change blades for the transverse cutting or perforation, for the whole of the width and progressively, of continuous and moving webs of paper, plastic or other materials, also with different thicknesses, wherein the fixed blade assembly and the rotary blade assembly are installed on the side members of a main base frame, with the drive means and with the means for adjusting the parallelism and the degree of interference between said two blades, said main base frame being installed removably on a secondary base frame, with means for adjusting the transverse alignment of the same main frame with the blade assemblies with respect to the longitudinal axis of the web to be cut, to allow dynamic execution on this web of a cut perpendicular to the longitudinal sides of the same web, this device being provided with means that allow quick installation and, when necessary, replacement with a new device each time both said blades require in-depth maintenance and adjustments, all for the purpose of limiting the downtimes of the packaging machine during replacement of the same device.

The device includes a fixed counter-blade and a rotating blade-holder on which a set of rotating blades is arranged. A web material which must be perforated or cut into sheets passes between blade-holder and counter-blade. A mutual contact sensor and an angular position sensor provide signals that allow correct positioning and functioning of the rotating blades and the counter-blade to be displayed on a human-machine interface.

An assembly and associated method for constructing a three dimensional article, such as a pallet, including a first station for feeding a sheet material in blank form, a second a second station for receiving and incising the blank, a third station for receiving the incised blank and which successively creases and folds the blank into an assembled article, and a fourth operator station for controlling each of said first, second and third stations. Also disclosed is a conveyor for removing the assembled article from the third station and transferring to a plastic coating operation.

A method for cutting a moving source material including: rotating a cutting cylinder including a blade; positioning a structural member in spaced relation from the cutting cylinder, wherein the space between the cutting cylinder and the structural member receives the source material; and positioning an anvil in the space. The anvil engages the source material when it is displaced between the cutting cylinder and the structural member. The method also includes: directing the blade into contact with the source material, whereupon the source material is pressed against the anvil and is severed by the blade, and the anvil is displaced by the cutting blade from a first retracted position to a second activated position; and applying an increasing biasing force to the moving anvil as it is displaced toward the second activated position so as to direct the anvil back to its first retracted position.
