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.
Abstract:
The invention relates to an approximately rectangular, separable multi-ply absorbent sheet based on cellulose wadding that includes at least three plies and that has a coefficient KNOVE = RSM X RST X A X G X Exp (12 x (E + Ep)) x (1/Exp (Sp)) > 75 000 where; RST = strength across the width of the sheet in N/m; RSM = strength along the length of the sheet in N/m; G = grammage of the sheet in kg/m2; E = thickness of the sheet in mm; Sp = flexibility of the sheet in N; A = absorption of the sheet in kg/m2 Ep = average thickness of one ply of the sheet in mm, where EP is greater than 0.115 mm. The invention also relates to the method of manufacturing such a sheet, and rolls composed of said sheets.
Abstract:
The invention relates to the embossing of a foil material with printing marks and pre-sized cover members for food containers (26), said embossing being partly carried out by means of sensors and by means of the regulated tensile force of embossing drums. Said partially embossed cover members (24) comprise a smooth surface area (24b) in the region of the container flange (27) and they are embossed in the rest of the surface area. The surface side (24') facing the container (26) can comprise a heat-sealable coating (25), preferably in the region of the width of the container flange (27). The heat-sealable coating (25') can also be applied in the embossed area (24'), so that the entire area (24') of the cover member is covered with a heat-sealable varnish. Partial embossing of the inventive cover members makes the food containers easy to use by the consumer and their embossed area (24a) also allows for satisfying stacking of said containers at the time of storage.

Abstract:
To provide a method of producing water-disintegrable paper capable of addressing a disadvantage of adhesion of a base-paper sheet to an embossing apparatus when the base-paper sheet impregnated with a water-soluble binder is embossed, achieving simple manufacturing and low manufacturing cost, and minimizing the likelihood of paper powder remaining on a dry surface of a cleaned object after use. To produce water-disintegrable paper, a base-paper sheet 2 in a non-wet state before a water-soluble binder is impregnated is embossed in order to form a bulking unit 17, made up of a plurality of uneven elements 12, on the base-paper sheet 2; a water-soluble binder solution 5 is sprayed to the base-paper sheet 2 having the bulking unit 17 formed, from outside of a face of the base-paper sheet 2 to impregnate the water-soluble binder solution 5 into the base-paper sheet 2; the base-paper sheet 2 impregnated with the water-soluble binder solution 5 is dried; the base-paper sheet 2 is folded after the drying; and an aqueous chemical solution is sprayed to the base-paper sheet 2 thus being folded to impregnate the aqueous chemical solution into the base-paper sheet 2.
