Abstract:
The invention relates to a process for producing a deep-nested embossed paper products comprising one or more plies of paper where the resulting embossed ply or plies of paper comprise a plurality of embossments having an average embossment height of at least about 650 µm and have a high finished product wet burst strength relative to the unembossed wet strength. The present invention relates to a process for producing deep-nested embossed paper products comprising the steps of a) delivering one or more plies (12) of paper to a deep-nested embossing device, b) conditioning the one or more plies of paper, wherein the conditioning step comprises heating the one or more plies of paper, adding moisture to the one or more plies of paper, or both heating and adding moisture to the one or more plies of paper, and c) embossing the one or more plies of the paper where the resulting embossed ply or plies of paper comprise a plurality of embossments having an average embossment height (31) of at least about 650 µm.
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:
Eine Vorrichtung (1) zum Einprägen eines vorgebbaren Musters in zumindest ein flächiges, zwischen zumindest zwei Prägewalzen der Vorrichtung durchgeführtes Material (4), wobei die Bewegungen der Prägewalzen miteinander synchronisiert sind, und die Prägewalzen (2, 3) weiters zumindest zwei Prägspuren (5, 6) aufweisen, wobei die Bewegungen der Prägewalzen (2, 3) mittels ineinander greifender und über Mantelflächen der Prägewalzen (2, 3) verteilter und unterschiedlichen Prägespuren (5, 6) zugeordneten Synchronisationsmittel (7, 8) oder elektronisch und/oder elektromechanisch miteinander synchronisiert sind, wobei die unterschiedlichen Prägespuren (5, 6) zugeordneten Synchronisationsmittel (7, 8) derselben Prägewalze (2, 3) zueinander versetzt angeordnet sind.

Abstract:
A flexible die (1) is for use in an embossing apparatus. The embossing apparatus includes a pair of flexible bases (2a, 2b) wound around a pair of respective cylindrical rollers disposed in opposing arrangement. A processed sheet (S) is passed through between the pair of cylindrical rollers so as to carry out Braille embossing. The pair of flexible bases (2a, 2b) include a female flexible base (2a) and a male flexible base (2b) that are configured to mate with one another. The male flexible base (2b) includes male projections (3b) corresponding to a Braille character to be formed on the processed sheet (S). The female flexible base (2a) includes female projections (3b) including depressions (30) configured to fit with the respective male projections (3b).
Abstract:
A set of dies for embossing or debossing is disclosed. The set has a female die (4, 80) and a male die (7, 67) each which has a steel backing plate (5, 47, 75). One of the dies is strongly magnetically attracted to a base plate (1, 68) which results in a weak magnetic attraction between the two dies (4, 7 or 67, 80). The weak magnetic attraction enables the set of dies to be substantially automatically self-aligning. Furthermore, such a set of dies can be used with a cutting and creasing die (50) to permit embossing or debossing simultaneously with cutting and/or folding during the same run.
Abstract:
Die Vorrichtung zum Prägen von Umhüllungsfolien weist eine Prägewalze (2) und zwei Gegenwalzen (3, 4) auf, wovon eine (2) über einen Antrieb (6) angetrieben ist, wobei die Prägeund Gegenwalzen in einer Pin-up - Pin-up Konfiguration ausgebildet sind, wobei mindestens die Prägewalze (2) aus dem Walzenzylinder herausragende Zähne (5) in der sogenannten Pin-up - Pin-up Konfiguration aufweist und die Zähne (5) der Prägewalze zum Prägen von Logos und/oder Verstärkungen pyramidenförmig oder konisch sowie abgeflacht sind und mindestens teilweise auch dem Antrieb der Gegenwalzen dienen und die Prägewalze (2) derart ausgebildet ist, dass sie im Online-Verfahren einsetzbar sind und beim Prägen nur eines Folienbandes einer Spulenbreite ein Einnicken derselben infolge Lücken in/oder zwischen Logound/oder Verstärkungszeilen und -reihen vermieden wird. Eine solche Vorrichtung ermöglicht unter anderem eine wesentlich rationellere Fertigung von Tippings für Zigarettenmundstücke ohne das Tipping zu verziehen, sowie einen kostengünstigen Austausch der Prägewalzen.
