Abstract

A machine for producing corrugated paper has a machine frame, a fluted roller and a glue application roller, which can be placed against the fluted roller and between the surface of which and the fluting the paper web to be provided with a corrugation and to be partially glued can be guided through. Provided between the fluted roller and the glue application roller and to the side of the fluting is at least one spacer, which maintains a safety gap with a gap width d between the surface of the glue application roller and the fluting, the gap width d being smaller than the smallest thickness of the paper web.

Claims
