Abstract

L'invention concerne des dispositifs d'orientation de particules magnétiques ou magnétisables, qui sont contenues dans un agent de revêtement (06) appliqué sur une face d'un substrat (02) en forme de bande ou de feuille. Les dispositifs sont pourvus d'un cylindre magnétique (33), qui est disposé dans le trajet de transport du substrat (02) à transporter et présente dans la zone de sa périphérie extérieure une pluralité de dispositifs (34) provoquant un champ magnétique, en bref des dispositifs magnétiques (34), une partie des dispositifs magnétiques (34) ou l'ensemble de ces derniers comprenant respectivement un aimant (44) pouvant être amené en rotation par un moteur (46) associé. Le cylindre magnétique (33) peut être monté en rotation dans des parois (38 ; 39) d'un bâti et au moins un transmetteur (63) est destiné à transmettre sans contact de l'énergie électrique et/ou des signaux de commande de l'extérieur dans ou sur le cylindre magnétique (33) rotatif, et comprend une partie (64) fixée au bâti et une partie (66) fixée au cylindre lors du fonctionnement.The invention relates to devices for orienting magnetic or magnetizable particles, which are contained in a coating agent (06) applied to one side of a substrate (02) in the form of a strip or sheet. The devices are provided with a magnetic cylinder (33), which is arranged in the transport path of the substrate (02) to be transported and has in the area of its outer periphery a plurality of devices (34) causing a magnetic field, in in short, magnetic devices (34), part of the magnetic devices (34) or all of the latter comprising respectively a magnet (44) which can be rotated by an associated motor (46). The magnetic cylinder (33) can be rotatably mounted in walls (38; 39) of a frame and at least one transmitter (63) is intended to transmit contactless electrical energy and / or control signals. outside in or on the rotating magnetic cylinder (33), and includes a part (64) fixed to the frame and a part (66) fixed to the cylinder in operation.
