Abstract (en)

[origin: WO2020020507A1] The invention relates to devices for aligning magnetic or magnetizable particles, which are contained in a coating means (06) applied on one side of a substrate (02), which is in the form of a web or sheet, having a magnet cylinder (33), which is arranged in the transport path of the substrate (02) to be conveyed and, in the region of the outer circumference thereof, has a plurality of devices (34) effecting a magnetic field, or magnet devices (34) for short, wherein some or all of the magnet devices (34) comprise a magnet (44) which is rotatable by an associated motor (46). The magnet cylinder (33) is rotatably arranged in frame walls (38; 39) of a frame, and at least one transducer (63) for contactless transfer of electrical energy and/or control signals from the outside is provided in or on the rotating magnet cylinder (33), which comprises a transducer part (64) fixed to the frame and a transducer part (66) fixed to the cylinder during operation.
