Abstract:
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.
Abstract:
Es wird ein Verfahren zur Herstellung einer Prägewalze durch Molettieren beschrieben, wobei auf einer Molette ein die Gravur der Prägewalze ausbildendes, aus einer Vielzahl von aus Reliefpunkten gebildeten identischen Einzelreliefen bestehendes Relief erstellt wird. Die Reliefpunkte eines jeden Einzelreliefs sind relativ zu den zugehörigen und in Ablaufrichtung der Molette folgenden Reliefpunkten des sich hieran anschließenden Einzelreliefs in Axialrichtung der Molette gesehen versetzt angeordnet und jeder Reliefpunkt weist eine radial in einer vorgegebenen Höhe über den Molettenmantel angeordnete und parallel zur Molettenachse verlaufende Relieffläche und eine sich bis zum Molettenmantel erstreckende Reliefmantelfläche auf, wobei für jedes Einzelrelief zur Erzeugung einer großformatigen Einzelgravur auf der Prägewalze eine Fläche zwischen 225 mm 2 und 25.000 mm 2 ausgewählt wird. Die Molette wird zum Gravieren der Walze achsparallel auf den Mantel der Prägewalze aufgesetzt und hierauf ablaufen gelassen, so daß durch eine mechanische Verformung die Gravur der Prägewalze erzeugt wird. Ferner wird eine gravierte Prägewalze beschrieben.
Abstract:
An embossing system (20) is provided for embossing and perforating a web (34) having a first embossing roll (22) having embossing elements (24) and a second embossing roll (22) having embossing elements (34), wherein at least a portion of the embossing elements of the first and second embossing rolls are substantially oriented in the cross-machine direction. The embossing roll may be crowned, may have alignment means, and may be provided with precision gearing.
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:
Disclosed are multi-ply embossed tissue products having improved softness, strength, embossment clarity and/or embossment height compared to prior art embossed tissue products. The multi-ply tissue products may comprise an embossed tissue ply having a basis weight less than about 25 grams per square meter (gsm) and relatively deep embossments, such as an embossment height from about 500 to about 1,000 μm and relatively narrow bottom portions compared to top portions. The combination of these elements provides an aesthetically pleasing and well-defined embossment, while improving important tissue product properties such as sheet and roll bulk and softness.
Abstract:
Disclosed are embossed multi-ply tissue products having 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 products further comprise a second ply having 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 sheet of absorbent paper includes at least one first and one second embossed plies of tissue having protuberances on the inward-facing side of the sheet corresponding to cavities on the outer side, with a first type of protuberances on the first ply, the first type of protuberances on the second ply, at least some of the first type of protuberances of the first ply contacting at least some of the first type of protuberances of the second ply, the first ply and the second ply include a second type of protuberances of frustoconical form, the first type of protuberances being partly adjacent to the second type of protuberances, the first type of protuberances of the first ply are aligned in a first direction and the first type of protuberances of the second ply are aligned in a second direction, the two directions forming a non-zero angle alpha between them.
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.
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.
