Abstract:
A method for obtaining an incision in an embossing roller using a hob to provide protuberances that are rounded on top and which improve the quality of the embossed material and reduce the wear of the mechanical components of the embossing units. The shape of the protuberances is obtained by machining the cylindrical surface of the roller placed between the tailstocks of the lathe using a hob that has teeth, the profile thereof being complementary to the cross-section of the protuberances. A portion of the hob with the teeth generates the grooves that define the side faces of the protuberances. The grooves between the teeth of the hob have a profile that is curvilinear in a cross-sectional view. With a double pass at two different inclinations of the surface of the roller, the protuberances of FIGS. 5 and 6 are generated.
Abstract:
A process for making an embossed web. A precursor web is provided between a forming structure and a static pressure plenum. The forming structure has a plurality of discrete apertures or depressions. Pressure is provided by the static pressure plenum against the precursor web and the forming structure to force the precursor web into the apertures or depressions of forming structure to form the embossed web. The resulting embossed web has a plurality of discrete extended elements.
Abstract:
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.
Abstract:
A supply of consecutive associated sheets in which at least first and second sheets in immediately preceding and succeeding relationship respective bear first and second arrangements of one or more design features is disclosed. The first and second arrangements differ from one another in one or more respects such that the second arrangement is not a substantial replicate of the first arrangement. The design features form part of a design pattern having a repeat length in the machine direction greater than the average sheet length in the machine direction, and a repeat length in the cross direction greater than the average sheet width in the cross direction.
Abstract:
The present disclosure relates to methods and apparatuses for mechanically bonding substrates together. The apparatuses may include a pattern roll including a pattern element protruding radially outward. The pattern element includes a pattern surface and includes one or more channels adjacent the pattern surface. The pattern roll may be positioned adjacent an anvil roll to define a nip between the pattern surface and the anvil roll, wherein the pattern roll is biased toward the anvil roll to define a nip pressure between pattern surface and the anvil roll. As substrates advance between the pattern roll and anvil roll, the substrates are compressed between the anvil roll and the pattern surface to form a discrete bond region between the first and second substrates. As such, during the bonding process, some yielded substrate material flows from under the pattern surface and into the channel to form a channel grommet region.

Abstract:
A rolled absorbent paper product. The rolled absorbent paper product includes an absorbent paper substrate having at least one ply with an emboss pattern comprising two visually distinct emboss design elements disposed in a plurality of predetermined, spaced-apart positions across the ply. The two emboss design elements comprise a first emboss design element occupying all but at least one of the positions in a first repeating pattern, and a second emboss design element occupying the at least one of the positions not occupied by the first emboss design element. The second emboss design element can be a word comprising a line emboss defining line-embossed letters wherein each letter comprises an open area within the line emboss. The first and second emboss design elements can each have an emboss area of from about 7% to about 25% and a difference in emboss area relative to each other of less than about 10%.
Abstract:
The aim of the invention is to create an embossing device for at least two-layered planar products such as toilet paper, tissues, or similar, which makes it possible to easily make high-quality planar products that are provided with decorative patterns. The aim is achieved by an embossing device for at least two-layered planar products such as toilet paper, tissues, and similar. Also, the embossing device has at least one first and at least one second couple of rollers, each of which is composed of an embossing roller and a squeezer.
