摘要:
A method of embossing an absorbent web with a machine direction undulatory structure is described. The web has a plurality of ridges extending in its machine direction occurring at a frequency, F, across the web and the method includes providing the web to an embossing station where the web is embossed between a first and second embossing roll, each of which rolls may be provided with a plurality of embossing elements configured to define a plurality of embossing nips. At least a portion of the embossing nips are substantially oriented in a cross-machine direction with respect to the web and have a cross direction length, L. The product FnullL is from about 0.1 to about 5.

The perceived softness of embossed tissue can be increased greatly while avoiding nesting when a particular pattern is embossed into the tissue. This pattern combines relatively shallow stitchlike bosses with deeper more sharply defined signature bosses. The stitchlike bosses can be rounded and arranged in wavy flowing intersecting lines. The signature bosses can be arranged in regions framed by the intersecting wavy flowing lines.

The present invention relates to a process for the manufacture of a soft thick single-ply tissue, such tissue product having a basis weight of at least about 15 lbs./3,000 square foot ream and having low sidedness, said tissue exhibiting a specific total tensile strength of between 40 and 75 grams per 3 inches per pound per 3000 square feet ream, a cross direction specific wet tensile strength of between 2.75 and 7.5 grams per 3 inches per pound per 3000 square feet ream, the ratio of MD tensile to CD tensile of between 1.00 and 2.75, a specific geometric mean tensile stiffness of between 0.5 and 1.2 grams per inch per percent strain per pound per 3000 square feet ream, a ratio of product cross direction stretch to base sheet cross direction stretch of at least about 1.4, a friction deviation of less than 0.225, and a sidedness parameter of less than 0.275.
摘要:
A method of embossing a sheet of non-woven fibrous web, and the resulting fibrous sheet structure, e.g. toilet tissue, with a series of identical boss elements arranged in a uniform pattern in a manner to avoid nesting of the embossments and resulting non-uniform product rolls when the sheet is rolled onto a mandrel. The embossments are uniformly spaced in rows which in the longitudinal direction form an angle in the range of 15.degree. to 23.degree. relative to the edge of the sheet or roll and an angle in the range of 40.degree. to 57.degree. relative to the cross direction of the sheet or roll.
摘要:
A method for embossing foil material by inserting the foil material in the roll nip between two rolls being provided with projections, each projection of a roll being surrounded on all sides by projections of the other roll, each projection of a roll is axially offset relative to the peripherally adjacent projections on the same roll, the projections of one roll form lines oblique to an axial line and so that the foil material from each projection peak on each roll is stretched to the surrounding projection peaks of the other roll.

Disclosed are embossed, multi-ply tissue products having consumer preferred physical properties and an aesthetically pleasing appearance. The products may have a first tissue ply having a molded topographical pattern and a first embossed pattern comprising a plurality of embossed elements disposed thereon, and a second tissue ply having a molded topographical pattern and a second embossed pattern comprising a plurality of dot emboss elements disposed thereon. The multi-ply tissue products generally have improved sheet bulk, such as a sheet bulk greater than about 15 cubic centimeters per gram (cc/g), and improved softness, such as an Average TS7 less than about 12.0 and more preferably less than about 11.0, such as from about 10.0 to about 12.0. The foregoing Average TS7 values may be obtained at a product geometric mean tensile strength (GMT) from about 800 to about 1,200 g/3″.

The present invention provides a patterned tissue product comprising a first surface with a first and a second pattern disposed thereon, the first pattern comprising a curvilinear design element having a first maximum segment length and the second pattern comprising a curvilinear design element having a second maximum segment length wherein the second maximum segment length is from about 50 to about 150 percent of the first maximum segment length.

The foil embossing device has an embossing unit (34) comprising at least two rollers (40, 41) at least one of which (40) is an embossing roller and is driven by a drive (5), at least the embossing roller having teeth (B) that project from the base cylinder for producing logos on the foil in a logo area (27) with teeth (39) that are different from the regularly arranged teeth (A) in order to produce a variable specific embossing pressure on the foil, the rollers having both axially and radially acting centering elements (4, 8) for centering the embossing roller (40) with respect to the other roller (41). It is thus possible to emboss logos in a substantially greater variety of designs and with higher accuracy than in the prior art and thus to achieve a sophisticated esthetic impression.
摘要:
Multi-layer bags may be formed to include first and second sidewalls joined along a first side edge, an opposite second side edge, and a closed bottom edge. The first and second layers may be non-continuously laminated together in discrete sections to include bonded regions in which the layers are bonded and unbonded regions in which the layers are not bonded. Such a bag may be described as a “bag-in-a-bag” type configuration in which the inner bag is non-continuously bonded to the outer bag. The inventors have surprisingly found that such configurations of non-continuous bonding provides increased and unexpected strength properties to the multi-layer films and bags.
