In einer besonders vorteilhafte Ausführung oder Konfigurierung der dreizylindrigen Ausgestaltung ist der dritte Zylinder 39 der Ausrichtvorrichtung 07 ebenfalls als Magnetzylinder 39 ausgeführt und weist im Bereich seines Außenumfangs in oben zum ersten Magnetzylinder 37 dargelegten Weise eine Mehrzahl von ein Magnetfeld bewirkender Elemente 42 auf, im Folgenden kurz auch Magnetelemente 42 bezeichnet, zur Orientierung zumindest eines Teils der magnetischen oder magnetisierbaren Partikel des auf dem passierenden Bedruckstoff 02 aufgebrachten Beschichtungsmittels 06 auf. Die Magnetelemente 42 können auf dem Umfang des zweiten Magnetzylinders 39 im selben Muster wie diejenigen des ersten Magnetzylinders 37 angeordnet sein. Dabei können sie in ihrer auf die Lage bei der Abwicklung auf einem auf dem Transportpfad durch die Ausrichtvorrichtung 07 hindurchgeförderten Substrat 02 bezogenen Position betrachtet mit den Positionen der ersten Magnetelemente 41 zusammenfallen oder aber z. B. sämtlich in gleicher Weise zu den Positionen der ersten Magnetelemente 41 in Umfangs- und/oder Axialrichtung versetzt sein. Ein Versatz in der jeweiligen Position kann beispielsweise derart bemessen sein, dass sich die dem Substrat 02 zugewandten Oberflächen der ersten und zweiten Magnetelemente 41; 42 bei Abwicklung auf dem Substrat 02 noch überschneiden, auf einer Seite gerade fortsetzen oder geringfügig, d. h. höchstens um die Hälfte ihrer Erstreckung in die betreffende Richtung, voneinander beabstandet sind. Im Fall eines Versatzes können sie dann zueinander versetzt auf das betreffende Druckelement 08 einwirken. Zusätzlich zum Versatz oder stattdessen können die ersten und zweiten Magnetelemente 41; 42 auch unterschiedlich ausgestaltet und/oder orientiert sein, so dass sie in der jeweiligen Ebene zu behandelnden Substrates 02 einen in Richtung und/oder Muster voneinander verschiedenen Feldlinienverlauf bewirken.In a particularly advantageous embodiment or configuration of the three-cylinder embodiment, the third cylinder 39 of the alignment device 07 is also designed as a magnetic cylinder 39 and has a plurality of elements 42 causing a magnetic field in the area of its outer circumference in the manner set out above for the first magnetic cylinder 37, briefly below also referred to as magnetic elements 42, for orienting at least some of the magnetic or magnetizable particles of the coating agent 06 applied to the printing substrate 02 passing through. The magnetic members 42 may be arranged on the periphery of the second magnetic cylinder 39 in the same pattern as those of the first magnetic cylinder 37. Included they can coincide with the positions of the first magnetic elements 41 in their position related to the position during the unwinding on a substrate 02 conveyed through the alignment device 07 on the transport path or B. all be offset in the same way to the positions of the first magnetic elements 41 in the circumferential and / or axial direction. An offset in the respective position can be dimensioned, for example, in such a way that the surfaces of the first and second magnetic elements 41; 42 still overlap during development on the substrate 02, continue straight on one side or are slightly spaced apart from one another, ie at most by half of their extent in the relevant direction. In the event of an offset, they can then act on the relevant pressure element 08 offset from one another. In addition to or instead of the offset, the first and second magnetic elements 41; 42 can also be designed and / or oriented differently, so that in the respective plane to be treated substrate 02 they cause a field line course that differs from one another in the direction and / or pattern.

Greiferleiste, vorgesehen, durch welche ein über den Zylinder 37; 38*; 39 zu fördernder Substratbogen 02 mit seinem vorlaufenden Ende aufgenommen und während einer Rotation des Zylinder 37; 38*; 39 über einen Winkelbereich hinweg gehalten werden kann. Zusätzlich können am Umfang mit einer Vakuumpumpe in Leitungsverbindung stehende Saugluftöffnungen vorgesehen sein. Obgleich ein derartiger Magnetzylinder 37; 38*; 39 ebenfalls dem Transport des Substrates 02 dient, wird er im Kontext der Ausstattung mit o. g. Magnetelementen 41; 42 hier nicht als Transportzylinder betrachtet bzw. bezeichnet. Die Magnetelemente 41; 42 können in oder an mehreren, z.

Im dargelegten und zu bevorzugenden Fall einer Zylindergruppe mit drei Zylindern 37; 38; 39; 37*; 38*; 39* können abweichend von oder alternativ zur o. g. besonders vorteilhaften Ausführung oder -konfigurierung (siehe z. B. Fig. 12 c)) hiervon abweichende Ausführungen oder Konfigurierungen realisiert und von Vorteil sein:
Ist lediglich eine einstufige Orientierung von im Beschichtungsmittel 06 enthaltenen Partikeln vorgesehen oder erforderlich, so kann in der Ausrichtvorrichtung 07 wie in der Basisausführung an lediglich einer der Zylinderpositionen für die Zylinder 37; 38; 39; 37*; 38*; 39*, z.

If only a single-stage orientation of the particles contained in the coating agent 06 is provided or required, then in the alignment device 07, as in the basic version, at only one of the cylinder positions for the cylinders 37; 38; 39; 37 *; 38 *; 39 *, e.g. B. that of the first cylinder 37, a magnetic cylinder 37 and at the other cylinder positions only as a transport cylinder 38; 39 * trained cylinder 38; 39 * must be provided (see e.g. Fig. 12 b) ),
