ABSTRACT:
A device for the production of one-sided corrugated paperboard with two corrugated rollers which corrugate a paper sheet. A glue mechanism for applying glue onto the corrugated paper sheet has a glue applying roller cooperating with a corrugated roller, a glue dosing element and a glue container. A pressing roller presses a cover sheet against the coated, corrugated paper sheet. Chambers are constructed on both sides of the glue applying roller. The chambers are sealed off, with their first edges against the first corrugated roller or the pressing roller and, with their other edges, are sealed off against the glue mechanism. The chambers have connections for high pressure sources, in order to press, by means of high pressure the corrugated sheet against the corrugated roller. Both edges of the pressure chambers sealing off against the glue mechanism cooperate with surfaces of the glue mechanism which do not convey any glue to the corrugated roller.
