Abstract: The invention relates to corrugated-board machine with a print-web printing line, which comprises a print-web unrolling device for the unrolling of a print-web and a printing device for printing the print-web. Furthermore, the corrugated-board machine has a corrugated-board manufacturing line with a cover-web unrolling device for the unrolling of a cover-web, a material-web unrolling device for the unrolling of a material-web to be corrugated, a device for manufacturing a corrugated-board web laminated on one side from the cover-web and the material-web, a lamination-web unrolling device for the unrolling of a lamination-web and a gluing unit for applying glue to the corrugated-board web laminated on one side. The corrugated-board machine further comprises a print-web transfer arrangement for transferring the print-web to the corrugated-board manufacturing line and for the use of the same as a lamination-web.

Abstract: An installation for the detection of projecting material defects in a paper web or corrugated cardboard web moved in a feed direction. The device comprises a sensor device comprising a first sensor unit with a first emitter for emitting first sensor beams and a second emitter for emitting second sensor beams and with a second receiver, wherein the first sensor beams run parallel to the material surface to be monitored of the paper web or corrugated cardboard web and travel along a first signal path S1 in-between. The sensor device further has a second sensor unit comprising a second emitter for emitting second sensor beams and a second receiver, wherein the second sensor beams run parallel to the material surface and travel along a second signal path S2 in-between. The first and second sensor units are oriented in such a way that the distance between the first and second sensor beams relative to the feed direction changes along their signal paths S1, S2.
