Embodiment Construction

[0036] In the figures, parts corresponding to each other or functionally similar are provided with corresponding reference numerals. The method and device are now described with the aid of exemplary embodiments.

[0037] figure 1 with 2 A schematic side plan view of an apparatus 100 for fabricating an antenna structure from a metal layer M laminated on an insulating backing T using a controlled milling tool and by monitoring the milling operation is shown. In one example, the backing T is a PET layer, preferably 35-36 μm thick, on which is calendered a 9 μm thick aluminum layer. The aluminum layer can be at least partially bonded to the backing T by the adhesive layer. The backing T with the metal layer M is configured like an endless belt-shaped product W in the variant shown here. In one embodiment, the metal layer M may also be a layer comprising copper and having a thickness of 15-40 μm, preferably 25-35 μm.

[0038] For milling operations, the device 100 has a milli...

Abstract

A milling operation for monitoring and controlling a milling tool interacting with a mold has the steps of milling at least one antenna structure out of a metal layer on a flexible product having a backing and a metal layer while guiding the product between the milling tool and the mold milling gap; outputting a light band passing through the milling gap in the running direction of the product or transversely to the running direction of the product by means of a light emitter, wherein the light band is dimensioned and the milling tool and the mold are arranged as Before the optical receiver receives the light band, the milling tool and the mold block the light band at least at one of the two longitudinal edges of the light band, wherein the transverse dimension of the light band characterizes the width of the milling gap between the milling tool and the mould; and, A signal representing the width of the milling gap is output to the controller by means of the light receiver; and at least an adjusting signal is output to an adjusting drive which influences the width of the milling gap between the milling tool and the mold.

Description

technical field [0001] Monitoring and control of milling operations, as well as systems and methods for performing them, are described herein. Background technique [0002] Significance and security documents are nowadays often generated centrally out of personalization data and then personalized locally, for example at registries, official bodies or companies authorized to issue such importance and security documents. During the personalization process, textual, numerical and / or photographic data that individually identify the respective holder of a document of importance and security (e.g. holder's name and address, date of birth, place of birth, holder's photograph , the holder's biometric data, etc.) are entered into the materiality and security file. These textual, numerical and / or photographic data are directly readable by the viewer. Transponder units are also increasingly used in importance and security documents. This allows a contactless and automatic readout of...
