摘要：A device for manufacturing a composite sheet () comprising at least onecorrugated sheet () and at least one flat sheet (), which is glued to the wave peaks of thecorrugated sheet (), said device comprising at least one fluted roller () for shaping and/ormaintaining the shape of the corrugated sheet (), said roller being covered with the

corrugated sheet () around a portion of its circumference during operation, and a gluingunit () for applying a liquid glue used to attach the corrugated sheet () to the flat sheet (),with said gluing unit () having a gluing roller () whose outer surface () is continuouslycoated with a glue film and whose axis is essentially parallel to that of the fluted roller (),said gluing roller being driven at approximately the same peripheral speed as that of thefluted roller (), and with it being possible, using means for moving the rollers closertogether (), to move said gluing roller, with its outer surface () against the portion of thecircumference of the fluted roller () which is covered with the corrugated sheet (), into aclose-up position forming a gluing gap that allows the glue to be transmitted to thewave peaks of the corrugated sheet (). The means for moving the rollers closer together() are designed so as to press the gluing roller () against the corrugated sheet () and thecorrugated sheet () against the fluted roller (). Because the gluing roller () is pressedagainst the corrugated sheet (), positional measurements of the gluing gap, which areprone to error, are unnecessary. Moreover, a highly uniform gluing pattern of the wavepeaks of the corrugated sheet () is maintained by providing means for adjusting andcontrolling the compressive force between the gluing roller () and the fluted roller ().
