The machine has an upper corrugated roller (5) mounted in a machine frame (1). Spacers (41, 42) are provided between the corrugated roller and a glue applicator roller (17). The spacers comprise thrust rings (36, 37) arranged at the glue applicator roller or at the corrugated roller and supporting surfaces (44) arranged at the corrugated roller or at the glue applicator roller. A safety gap (40) is limited during contact of the thrust rings and the supporting surfaces. A cleaning scraper rests against the supporting surfaces. |
