The assembly comprises a first transverse position detecting device, upstream the fluting device, for detecting the first material web, a second transverse position detecting device, upstream the pressing device, for detecting the second material web and a signal processing unit, which is capable of actuating a unrolling device for unrolling the second material web so that in the device for producing a corrugated board web it is transversally displaced correspondingly.

In a method for high speed printing of web-based media, a medium is pulled along a media transport path to a pulling transport mechanism. The orientation of the medium with respect to the media transport path is sensed and this orientation is compared to a reference orientation to detect an orientation error. If an orientation error is detected, one or more of the following steps is performed: adjusting a print job for an image to be printed on the web medium; adjusting the transport speed; emitting a communication signal; and stopping the pulling transport mechanism and the image forming unit. It is the insight of the inventor that productivity may be increased by allowing a “tight winding” printing system to start printing at relatively high speed and reduce this speed only when significantly large deviations in the orientation of the web are detected.

A meandering correction apparatus includes a transport mechanism, an orientation measurement part, a Young's modulus calculation part, a meandering prediction part and a meandering correction part. The transport mechanism transports an elongated strip-shaped base material in a longitudinal direction thereof along a transport path. The orientation measurement part measures fiber orientations of the base material in respective measurement regions on the transport path, the measurement regions being different in widthwise position from each other. The Young's modulus calculation part calculates Young's moduli of the base material for the respective measurement regions, based on the fiber orientations. The meandering prediction part predicts subsequent meandering of the base material, based on the Young's moduli, to output meandering prediction information. The meandering correction part corrects the widthwise position of the base material, based on the meandering prediction information. The meandering correction is made based on the fiber orientations of the base material. Thus, the widthwise position of the base material is corrected without depending on only edge sensors.

An apparatus (un-interleaver) for unwinding a roll of material interleaved with another material, and for separating the materials, includes a first platform, a second platform, a tension-sensor, an edge-sensor, and a controller. The controller monitors signals generated by the tension-sensor and the edge-sensor, and in response to the signals: a) causes the speed at which the second platform rotates to change to maintain a predetermined tension in the second material as the second material travels from the first platform toward the second platform, and b) causes the second platform to move relative to the first platform to align the edge of the second material traveling toward the roll of second material with the edge of the second material in the roll.

A method and a vacuum-coating system (10) for coating a strip-shaped material (11), in particular made of metal, are disclosed. Thereby, the strip-shaped material (11) is moved over a conveying section (12) in a transport direction (T) and vacuum-coated within a coating chamber (14) in which a vacuum is applied. When viewed in the transport direction (T) of the strip-shaped material (11), at least one trimming shear (38) is arranged upstream of the coating chamber (14), with which the strip-shaped material (11) is trimmed at at least one strip edge, preferably at both strip edges, in order to produce a constant width for the strip-shaped material (11) over its longitudinal extension.
