摘要:
Es wird ein Verfahren zur Kennzeichnung eines Artikels, umfassend ein Formgedächtnispolymer (FGP) mit einem visuell und/oder maschinell lesbaren grafischen Element auf der Oberfläche des Artikels vorgeschlagen, umfassend die Schritte: - Vorbehandeln der Oberfläche des Artikels; - Einfärben der Oberfläche des Artikels mit einer Farbstofflösung, die einen organischen Farbstoff und ein organisches Lösungsmittel enthält, - Reinigen und Trocknen der Oberfläche des Artikels; - Gravieren durch zumindest teil weises Abtragen der Oberfläche des Artikels. Vorteilhafterweise eignet sich das Färbeverfahren für das Färben der Oberfläche eines Formgedächtnispolymers (FGP), wobei in die gefärbte Oberfläche eine Information in Form eines Codes oder einer sonstigen Kennzeichnung eingraviert wird. Die Färbung bewirkt einen verstärkten Kontrast und damit die erleichterte maschinelle Lesbarkeit der Kennzeichnung bzw. Kodierung, ohne die sonstigen Eigenschaften des FGP zu beeinträchtigen.
摘要:
There is provided a postage stamp (14) construction formed of a plurality of postage stamps (14) adhered to a currency sized release liner (30) by an ooze resistant pressure sensitive adhesive (28) which construction coated with a polymeric coating (22) of the face of the stamp (14) and the undersurface of the release liner (30) and dispensable from an automatic teller machine.
摘要:
A substrate, such as a postage stamp, is provided with a layer of adhesive thereon, the layer of adhesive being further coated with a protective layer which is soluble in a solvent in which the adhesive is substantially insoluble. Preferably, the adhesive is a pressure-sensitive adhesive, and the protective layer is formed from an edible water-soluble polymer such as gelatine.

The present invention relates to the field of cold transfer postage stamps for mail pieces (0), methods for manufacturing said postage stamps and uses thereof. In particular, it relates to cold transfer postage stamps comprising a first release coated substrate (1), one or more printed layers (2) comprising one or more security features (6), a white opaque printed layer (3), a pressure sensitive adhesive layer (4), and a second release coated substrate (5).

An identifying label (10) which can be adhered at ambient temperatures to an object which is to be exposed to firing temperatures above 400 DEG C includes a base layer (11) of a bifunctional, inorganic pressure sensitive adhesive; a topcoat (15) receptive to identifying marking having a silicone binder (16); and, heat resistent, inorganic particles (17) in the topcoat (15) which interact with pyrolysis products formed by the firing to form an abrasion resistent identifying label (10). In a preferred embodiment, there is a woven cloth of fiberglass (14) between the base layer (11) and topcoat (15); and, a release liner (13) covering the underside of the base layer (11).
摘要:
A composite material comprising a base liner and a releasable face layer adhered thereto by a pressure sensitive adhesive wherein the base liner has a skin layer on its surface proximate to the pressure sensitive adhesive which is more difficult to cut than the remainder of the base liner materials such that when the composite is subjected to die cutting to allow portions of the face layer to be selectively removed, the die cutter will not penetrate through the base liner to any substantial extent.
摘要:
A method is proposed for marking an article comprising a shape memory polymer (SMP) with a visually readable and/or machine-readable graphic element on the surface of the article, comprising the following steps: - pretreating the surface of the article; - colouring the surface of the article with a dye solution comprising an organic dye and an organic solvent; - cleaning and drying the surface of the article; - engraving by at least partially ablating the surface of the article. The colouring method is suitable advantageously for colouring the surface of a shape memory polymer (SMP), with information in the form of a code or other marking being engraved into the coloured surface. The coloration heightens the contrast and thus the facilitated machine-readability of the marking or coding, without adversely affecting the other properties of the SMP.
摘要:
According to the invention, a paper sheet is inserted between the sheet to be printed and the sheet for protecting the adhesive gum coating. This sheet is caused to adhere, by means of a water-soluble glue, to the side of the sheet being printed, while the other side thereof receives the adhesive coating which is protected by the system already used.
摘要:
The invention relates to the fields of postal stamps, automated postal sorter machines, sorting processes, and postal metering devices. The prior art of postal stamps and processing systems failed to provide for automatic sorting and processing without replacing the usual stamp with a machine printed decal thus: 1) depriving the ordinary stamp user from using the system which requires a special stamp printing machine, and 2) destroying the philatelic nature of the stamp for the hobby of stamp collecting. The invention solves these problems by providing a multi-part stamp where machine readable data are entered by the ordinary user without the need for a special machine. One portion of the stamp (42) includes the ordinary stamp attributes thereon and another portion (43) carries marking indicia (47) and (48) which are to be filled with the information of the points of origin and destination. The stamp portions may be separated along lines of perforation, resulting in one piece being the typical unaffected stamp collected by millions of stamp collectors. In addition, automatic postal sorting apparatus, sorting process, and a metering device which all use the new features of the invented stamp are introduced to facilitate the implementation of the automatic sorting of mail.
摘要:
A label applicator, labelling system and method are disclosed. The label applicator (10) is configured to be applied to a surface of an item to be labelled. The label applicator (10) includes a mask (4000) that is separable from the label applicator (10). The label applicator (10) is configured to direct passage of a mark onto the surface of the item and, upon separation, the label applicator directing the mask (4000) over the mark to thereby form a label.
