Abstract

There is described a cylinder body (10) for orienting magnetic flakes contained in an ink or varnish vehicle applied on a sheet-like or web-like substrate, which cylinder body (10) has a plurality of magnetic-field-generating devices (50, 60) disposed on an outer circumference of the cylinder body (10). The cylinder body (10) comprises a plurality of distinct annular supporting rings (40) distributed axially along a common shaft member (20), each annular supporting ring (40) carrying a set of magnetic-field-generating devices (50, 60) which are distributed circumferentially on an outer circumference of the annular supporting rings (40).
