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:
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:
Apparatus for making micro-textured webs. The apparatus comprises a pair of mated forming structures having a first forming structure (102), a second forming structure (103), and a deformation zone (130); wherein at least the first forming structure (102) comprises voids (30,38), and wherein at least the second forming structure comprises protrusions (20,26) wherein at least one protrusion has center-to-center spacings of less than about 800 microns with at least three of its adjacent protrusions. The voids (30,38) of the first forming structure (102) are engagable with the protrusions (20,26) of the second forming structure (103) at an engagement position to form a micro - textured web (60). In another embodiment, the apparatus comprises a pair of counter- rotating rollers wherein the first roller comprises grooves having a length, wherein the length of the grooves are oriented at an angle different from the machine direction.
Abstract:
An embossing apparatus for applying an embossing pattern to a wrapper for a smoking article, the embossing apparatus configured so as to act to at least partially minimise the reduction, in at least one direction, in the tensile strength of the wrapper resulting from the application of said embossing pattern.
Abstract:
An embossing and laminating machine is described comprising a first embossing cylinder (3) with a surface provided with a first set of protuberances (P3), a second embossing cylinder (5) with a surface provided with a second set of protuberances (P5), the said two embossing cylinders forming a nip, and a first and a second pressure roller (7, 9) interacting with the first and the second embossing cylinder (3, 5) respectively; and in which the protuberances of the said first and the said second sets (P3, P5) are made in such a way that in the said nip some of the protuberances of the first set (P3) coincide with some protuberances of the second set (P5), while other protuberances of the first set are out of phase with corresponding protuberances of the second set. In order to reduce wear, the two embossing cylinders have different diameters.
Abstract:
The embossed multi-ply tissue products have improved bulk, softness, strength, embossment clarity and/or embossment height. The multi-ply tissue products comprise a first tissue ply having a plurality of embossments arranged in an open first pattern such as open, continuous line elements, which may be substantially oriented in the cross-machine direction (CD). The second ply of the multi-ply tissue product have a plurality of micro-embossments disposed in a second pattern. The first and second embossing patterns are such that when the first and second plies are joined to form the product the first and second patterns are not in registration with one another.
Abstract:
A non-continuously laminated structure of thermoplastic films comprises thermoplastic films with differing material compositions and differing functional benefits. In particular, one or more embodiments comprise thermoplastic films that are co-extruded separately and then combined together by a post-extrusion bonding process. The differing composition of the various films of the non-continuously laminated structure of thermoplastic films and the post-extrusion bonding process, provide the structures with the functional benefits of the individual films.

Abstract:
An embossing system is provided for embossing at least a portion of a web comprising a first roll and at least a second roll. The first roll and second roll may define a first nip for embossing the web. At least one of the first roll and the second roll has elongated embossing elements extending substantially in the machine direction and optionally at least one of the first and second rolls has elongated embossing elements extending substantially in the cross-machine direction. At least one of the first roll and the second roll may also have perforate embossing elements extending substantially in the cross-machine direction that may or may not be elongated. The embossing elements are capable of imparting one or both of a cube embossing pattern or a perforate emboss on the web. The web may be a cellulosic fibrous web, a portion of which is lignin-rich, high coarseness fiber having generally tubular fiber configuration. In addition, the web may be creped with an undulatory creping blade.
