Abstract

A device is provided for aligning magnetic or magnetizable particles, which are contained in a coating that is applied to a first side of a web-type or a sheet-type substrate. An application device is arranged in the transport path of the substrate, by the use of which, the coating is applied or is applicable to the first side of the substrate, in at least one application site. A first cylinder, which is embodied as a magnetic cylinder, is arranged in the transport path of the substrate to be transported downstream of the application device and comprises a plurality of elements creating a magnetic field in the region of the outer periphery of the first cylinder. Another cylinder, which is embodied as a magnetic cylinder, is arranged in the transport path of the substrate to be transported and comprises a plurality of elements creating a magnetic field in the region of the outer periphery of that cylinder. A drying device or an hardening device is arranged on the transport path between a site of a winding-on of the substrate on the first cylinder and a site of a winding-on of the other cylinder. The first cylinder, which is embodied as the magnetic cylinder, is arranged in the trans…
