A device is provided for aligning magnetic or magnetizable particles, which are contained in a coating that is applied to a first side of a web-type or a sheet-type substrate. An application device is arranged in the transport path of the substrate, by the use of which, the coating is applied or is applicable to the first side of the substrate, in at least one application site. A first cylinder, which is embodied as a magnetic cylinder, is arranged in the transport path of the substrate to be transported downstream of the application device and comprises a plurality of elements creating a magnetic field in the region of the outer periphery of the first cylinder. Another cylinder, which is embodied as a magnetic cylinder, is arranged in the transport path of the substrate to be transported and comprises a plurality of elements creating a magnetic field in the region of the outer periphery of that cylinder. A drying device or an hardening device is arranged on the transport path between a site of a winding-on of the substrate on the first cylinder and a site of a winding-on of the other cylinder. The first cylinder, which is embodied as the magnetic cylinder, is arranged in the transport path of the substrate to be transported on the second side thereof. The drying or the hardening device is oriented in the transport path of the substrate to be transported on the first side thereof.

A cylinder is usable, in particular, for aligning magnetic of magnetizable particles, which are contained in a coating medium that is applied to a first side of a web-like or a sheet-like substrate, which cylinder, in the region of its outer circumference, has a plurality of elements effecting a magnetic field, magnetic elements for short. The magnetic elements are arranged in or on a plurality of ring elements that are spaced axially apart from one another and that are positionable in the axial direction on a shaft, in or on which ring elements, in turn, a plurality of magnetic elements are respectively arranged one after the other in the circumferential direction. At least two adjacent ring elements, each have a covering element, forming a part of the cylindrical lateral surface of the cylinder and extending in the circumferential direction, at least over the circumferential region populated with magnetic elements. The covering elements of two ring elements adjacent to each other have, on their sides facing each other in the axial direction, a plurality of projections alternating in the circumferential direction with recesses and offset in a circumferential direction in such a way that, during a relative movement of the two ring elements towards each other, the projections on the covering element of one ring element engage, in the manner of teeth, in corresponding recesses of the other ring element, and, as seen in the circumferential direction, can overlap. A security paper printing machine, having such a cylinder, is also disclosed.

The present invention provide a full-servo label inspection machine and a control method thereof; the machine includes a frame, the frame is provided with an unrolling mechanism, a rolling mechanism, a visual inspection mechanism, a label removal mechanism, and a label replacement mechanism. In the label removal mechanism, when the paper pressing roller is at the label removal position, it presses the material to be inspected downwards to form an angle of less than 180 with the rear end of a label removal plate. After a defective label on the material to be inspected passes the label removal plate, a front end of the defective label curls up and eventually sticks onto the label removal paper. The present invention allows fully automation of the removal and replacement of labels, achieving high inspection efficiency and accuracy.
