Abstract:
An embossing roll for producing fibrous products, has a structurized embossing surface suitable to run against an anvil roll. The structurized embossing surface includes male protrusions or female depressions starting from a base circumferential surface of the roll. The embossing pattern is characterized by the following features: the base areas of selected male protrusions or female depressions in the base circumferential surface are different; the heights or depths of selected male protrusions or selected female depressions in a radial direction of the roll and starting from the base circumferential surface are different; and the angles between sidewall sections and the adjacent base circumferential surface of selected male protrusions and/or female depressions are different.
Abstract:
A method relates to the production of paper rolls for examination tables, obtained from a tape (100) of embossed paper, having two layers (10, 20), joined together. The band (100) is obtained in known way from two continuous webs (1, 2), subjected to subsequent steps of embossing, glue (C) application, coupling and stabilization. The method includes applying measured quantities of a sanitizing and/or disinfectant substance (S) between the two layers of embossed paper (10, 20) before their joining; preferably, the substance (S) is applied to the same continuous web (1) that is aimed at receiving the glue (C), after the embossing step and contemporarily with the glue (C) application, by spot-application of a mixture (M) in aqueous solution containing suitable percentage of the glue (C) and sanitizing substance (S) to the tops (11A) of the embossing relieves (11.) In this case, the application means (240) for sanitizing substance (S) are formed by the same means (220) for applying the glue (C).
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 multi-ply absorbent sheet of cellulosic fiber with continuous outer surfaces is provided an absorbent core between the outer surfaces. The absorbent core includes a non-woven fiber network having: (i) a plurality of pileated fiber enriched regions of relatively high local basis weight interconnected by way of (ii) a plurality of lower local basis weight linking regions whose fiber orientation is biased along the direction between pileated regions interconnected thereby, and (iii) a plurality of fiber-deprived cellules between the fiber enriched and linking regions, also being characterized by a local basis weight lower than the fiber enriched regions. The cellules provide a sponge-like internal structure of low fiber density regions.
Abstract:
An apparatus for providing a multi-ply embossed paper product having a first pressure roll; embossing roll with a plurality of embossing protrusions, each protrusion having a distal end; a second pressure roll; and a marrying roll. The first pressure roll and the embossing roll are juxtaposed in an axially parallel relationship to form a first nip therebetween. The first nip has a first nip width, and the first pressure roll and embossing rolls are adapted to receive a first paper web at the first nip. The second pressure roll and the embossing roll are juxtaposed in an axially parallel relationship to form a second nip therebetween. The second nip has a second nip width, and the second pressure roll and embossing rolls are adapted to receive the first paper web, after the first paper web has traversed the first nip, and a second paper web at the second nip. The marrying roll is juxtaposed in an axially parallel relationship with the embossing roll to form a third nip therebetween. The marrying roll and embossing roll are adapted to receive the first paper web and the second paper web, after the first and second paper webs have traversed the second nip, at the third nip and marry the second paper web to the first paper web.
Abstract:
A method for producing a deep-nested embossed product is disclosed. The method comprises the steps of: a) providing an embossing apparatus having mating first and second embossing members; b) providing the first embossing member with a plurality of discrete embossing elements in a non-random pattern; c) providing the second embossing member with at least one linear embossing element; d) coordinating the at least one linear embossing element with the non-random pattern of first embossing elements; e) aligning the first embossing member and the second embossing member so that the non-random pattern of first embossing elements nest with the at least one linear embossing element to an engagement depth of greater than about 0.01 mm; f) providing one or more plies of material to the embossing apparatus; and, g) passing the one or more plies of the material between the first and second embossing members to produce the deep-nested embossed product.
Abstract:
