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.

Disclosed herein are a multi-cell tab cutting apparatus for a plurality of cells, which have a plurality of tabs formed at one side, and a method therefor. The multi-cell tab cutting apparatus includes a base frame, a cell tab fixer connected to the base frame and configured to fix and support the plurality of tabs, and a cutter positioned at the base frame and configured to cut the plurality of tabs through driving.

A multilayered printed matter is made up of a plurality of layers formed on a medium, including a front layer and a back layer with patterns printed thereon, and a white layer and a black layer interposed between the front layer and the back layer so as to conceal the back layer to be invisible from the front-layer side. The system for producing the multilayered printed matter includes a computer that executes a printing step of moving the medium and an inkjet head relative to each other using a moving device and printing the front, back, white, and black layers on the medium using the inkjet head, and a cutting step, subsequent to the printing step, of moving the medium and a cutting blade relative to each other using the moving device and cutting the medium using the cutting blade.

A method, a cutting device and an apparatus wherein, at cusp-shaped recesses obtained by die cutting on a ribbon in order to obtain pouches with rounded corners, the ribbon is cut transversely by means of at least two strokes of a blade. A relative translation is performed, between the first stroke and the second stroke, between the cutting plane and the ribbon substantially along a feeding direction of the ribbon, so as to level with the second stroke any cutting defects of the first stroke in the region of the recess.

A method for manufacturing unit cells includes preparing a pre-cell having a first separator sheet and a plurality of first electrodes disposed on the first separator sheet while being spaced apart from one another; forming a cutting guide line having a plurality of though-holes spaced apart from one another on the pre-cell; and cutting the pre-cell along the cutting guide line to form a plurality of unit cells. An apparatus for manufacturing unit cells includes a hole-forming unit configured to form a cutting guide line on a pre-cell having a separator sheet and electrodes disposed on the separator sheet where the cutting guide line has a plurality of though-holes spaced apart from one another; and a cutting unit configured to cut the pre-cell along the cutting guide line to form a plurality of unit cells.

A cutting mechanism is provided for a dunnage conversion machine 10 that selectively cuts dunnage sheet stock drawable through the cutting mechanism. The cutting mechanism includes a frame and a pair of opposed cutting blades through which the sheet stock is drawable. The cutting blades include a driven blade and a biased blade, each supported relative to the frame for movement into and out of contact with one another. The driven blade is movable towards the biased blade to cut the sheet stock. The biased blade is biased against movement away from the driven blade to allow for self-adjustability to counter wear of one or both of the opposed blades. Contact of the opposed blades with one another causes the biased blade to be deflected away from the driven blade.

A method for repairing rivet tape includes steps of cutting portions of the rivet tape on each side of a break to define at least three aligned coplanar rivet tape edges, abutting the at least three aligned coplanar rivet tape edges to define a seam, and joining the at least three aligned coplanar rivet tape edges to one another. The seam may define a Z shape. One or more rivets may be removed to expose rivet apertures on each side of the break before the steps of cutting, abutting, and joining. The step of joining is accomplished by at least one adhesive strip disposed on a surface of the rivet tape and dimensioned to overlie the at least one or more exposed rivet apertures. Adhesive strips may be disposed on each opposed surface of the rivet tape length. In other aspects, workstations comprise devices for practicing the described methods.

An anti-stuck driving device comprises: a movable blade, a movable blade driving unit, and a controller. The movable blade driving unit comprises a transmission assembly, a motor configured to drive the transmission assembly, and a connecting element connected between the transmission assembly and the motor. The transmission assembly links the movable blade moving back and forth linearly. The controller connects to the motor. When the movable blade is stuck, the controller controls the motor to drive the connecting element to rotate in reverse to separate the transmission assembly and the connecting element, and release a resistance of the transmission assembly. The present invention also discloses a printer using the anti-stuck driving device with malfunction repairing.

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.
