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.

A device for measuring elevations on a surface of a rotary body provided as a cylinder, sleeve, or plate for a graphic industry machine, for instance a flexographic printing plate, includes a first motor rotating the rotary body about an axis of rotation and a measuring device including at least one radiation source, at least one line scan camera, and a computer taking contact-free measurements and combining individual images of the line scan camera to form a joint image. The measuring device preferably includes a reference object such as a wire tautened in an axially parallel direction, a second motor and, if required, a further second motor adjusting the measuring device and/or reference object perpendicular to the axis of rotation. The device provides fast high-precision measurements of elevations such as flexographic printing dots. A system includes the measuring device and a flexographic printing press.

A device for measuring a surface or elevations of the surface of a rotary body provided as a cylinder, a roller, a sleeve, or a plate for a graphic industry machine, includes a first motor for rotating the rotary body about an axis of rotation and a measuring device including at least one radiation source, at least one area scan camera, and at least one computer used to take contactless measurements on the surface which is permanently sticky and/or compressible and/or porous and therefore difficult to measure. The measuring device uses a virtual reference object saved on the computer to determine the concentricity of the rotary body on the basis of the measurement results. A system including the measuring device and a flexographic printing press is also provided.

A printing assembly (400) may include a first continuous cylinder (420) and a first jogging assembly (424). The first continuous cylinder (420) may be configured to apply print media to a flexible substrate (300) responsive to contact with the flexible substrate. The first continuous cylinder (100, 420) may include a plurality of partitions (210, 220, 230, 240, 250, 260) configured such that only one of the partitions is aligned for contact with the flexible substrate at any given time, and each of the partitions may have a unique print characteristic associated therewith. The first jogging assembly (424) may be operably coupled with the first continuous cylinder (420) to move the first continuous cylinder along an axis thereof to change alignment of the partitions relative to the flexible substrate.

A cylinder is arranged to receive one or more hollow cylinders on an outer surface of the cylinder. The cylinder has at least one movable stop with at least one movable element. In an idle position the at least one movable element does not protrude beyond the outer surface of the cylinder and allows hollow cylinders to be slid over the cylinder, and in an active position it protrudes beyond the outer surface of the cylinder and acts as a mechanical stop for hollow cylinders. The at least one movable element can be moved from the idle position to the active position, and vice versa, by means of a rotary movement. A method for positioning a hollow cylinder on a cylinder of this kind.

The object of the invention is a magnetic cylinder, in particular for a device for printing, having a cylindrical body and two bearers mounted at the ends of the body, wherein at least one bearer includes a cylindrical flange adjacent to the body, wherein a plurality of magnetic channels are formed in the body extending substantially parallel to the longitudinal axis of the body, radially spaced from the longitudinal axis of the body, wherein corresponding magnetic assemblies are inserted into the magnetic channels. The object of the invention is also a method for producing the magnetic cylinder.
