Estimating the term…
The apparatus and methods of the present disclosure relate to devices comprising spinning magnets driven by electric motors for use with printing or coating equipment. These devices and methods are for orienting magnetic or magnetisable pigment particles in an unhardened coating composition on a substrate. Specifically, these devices and methods are for producing optical effect layers. The apparatus comprises a holder, onto which is mounted a motor and a permanent magnet assembly. The motor is configured to spin the permanent magnet assembly. The holder is configured to be removably fixed to a base of a rotating magnetic cylinder (RMC) or a flatbed printing unit.
An apparatus for producing an optical effect layer comprising:
A method of modifying an existing rotating magnetic cylinder or a flatbed printing unit having non-spinneable permanent magnet assemblies, the method comprising removing one or more non-spinneable permanent magnet assemblies from the rotating magnetic cylinder or the flatbed printing unit and replacing them with one or more spinneable permanent magnet assemblies, characterized wherein the one or more spinneable petinanent magnet assemblies are removeably fixed to a circumferential mounting groove of the rotating magnetic cylinder or a mounting recess of the flatbed printing unit.
