Abstract: A method forms a vapor-deposit layer of needle-shaped x-ray luminophore containing at least one alkali metal doped with europium on a carrier. The method includes placing a mixture of Eu3O4Hal and at least one alkali halogenide in a molybdenum vaporizer, heating the mixture to simultaneously vaporize the mixture and to deposit it on a carrier, wherein Hal is at least one halogenide from a group consisting of F, Cl, Br and I. The ratio of the Eu concentration of the alkali halogenide layer in the proximity of the substrate to the Eu concentration of the alkali halogenide layer in the proximity of the surface can preferably be reproduced with a factor of 0.4 to 1.2, and preferably between 0.6 and 0.8.

Abstract: A chamfer cutting device for cutting packaging materials (9) comprises a die (1) and a knife part which has a plurality of knives (2). The die (1) can be moved toward the knife part in order to carry out a cut. The knives (2) are arranged individually in the knife part in a force-dependent manner in such a way that their position with respect to the tool plate (4) varies in a defined way as a function of the force produced by contact with the packaging material (9) or the die (1). In the event of contact between the knife (2) and the die (1), a force acts on the knife (2) which does not exceed a predefined maximum force. The chamfer cutting device has the advantage that the die (1) can be guided right up to the knives (2).
