Abstract:
Provided is a pair of plates for a rotary processing machine having the following configuration and a method of mounting the same by which the pair of plates can be mounted on the respective outer circumferential surfaces of a pair of cylinders with high precision. When a female recessed plate and a male raised plate are overlapped with each other so as to make processing portions of the female plate correspond to those of the male plate, fitting protrusions are fitted into respective fitting portions. Accordingly, the movement of the fitting protrusions is restricted both in the width direction of the plates and in the mount direction of the plates. Concurrently, guiding protrusions are respectively inserted between corresponding pairs of guide protrusions in the guiding portions. Accordingly, the guiding protrusions are guided so that relative movement of the guiding protrusions is allowed only in the mount direction.

Provided is a pair of plates 110, 120 for a rotary processing machine 100 having the following configuration and a method of mounting the same by which the pair of plates 110, 120 can be mounted on the respective outer circumferential surfaces of a pair of cylinders 101, 102 with high precision. When a female recessed plate 110 and a male raised plate 120 are overlapped with each other so as to make processing portions 111, 121 of the female plate 110 correspond to those of the male plate 120, fitting protrusions 123a, 123b are fitted into respective fitting portions 113a, 113b. Accordingly, the movement of the fitting protrusions 123a, 123b is restricted both in the width direction of the plates 110, 120 and in the mount direction of the plates 110, 120. Concurrently, guiding protrusions 124a, 124b are respectively inserted between corresponding pairs of guide protrusions 114aa, 114ab, 114ba, 114bb in the guiding portions 114a, 114b. Accordingly, the guiding protrusions 124a, 124b are guided so that relative movement of the guiding protrusions 124a, 124b is allowed only in the mount direction.
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:
Packaging material is embossed by passing between two fine teethed rotating rolls, which are pressed against one another. Both the rolls have fine pyramidal teeth on them. The teeth are designed and manufactured such that the apex angle of the pyramids of one of the rolls is different from the apex angle of the pyramid of the other roll. This differential angle of the two pyramids will provide operational clearance for each teeth and thus reduce the friction between the two rolls and increase the flexibility of the system in the practical dynamic condition of the embossing in the packaging industry. This will also function as one or more variable parameter to vary the quality and texture of embossing.

Abstract:
Die Vorrichtung zum Prägen von Folien weist eine Prägeeinheit (34) auf, die mindestens zwei Walzen (40, 41) enthält, wovon mindestens eine (40) eine Prägewalze ist und über einen Antrieb (5) angetrieben ist, wobei mindestens die Prägewalze vom Grundzylinder wegragende Zähne (B) zur Bildung von Logos auf der Folie einen Logobereich (27) mit Zähnen (39) aufweist, die von den regelmässig angeordneten Zähnen (A) verschieden sind, um auf der Folie einen veränderlichen spezifischen Prägedruck erzeugen, wobei die Walzen Zentrierelemente (4, 8) zum Zentrieren der Prägewalze (40) bezüglich der anderen Walze (41) aufweist, die sowohl axial als auch radial wirksam sind. Dadurch ist es möglich, Logos mit wesentlich höherer Gestaltungsvielfalt und Genauigkeit zu prägen als vorbekannt, um einen ästhetisch anspruchsvollen Eindruck zu erzielen.
