ABSTRACT:
Apparatus is provided for the production of a corrugated pasteboard having a cover coating on at least one side. The apparatus includes a toothed corrugating element, a toothed corrugating counter-element co-operating therewith, a glue applicator and a drying apparatus. At least one corrugating element is an endless element (2) which loops at least partially around the other element (1). In this manner the noise generation and roll wear are reduced, the quality of the corrugated cardboard is improved, the paper consumption and difficulties of adjustment of parts of the apparatus are reduced and the feed and introduction of the paper web are facilitated.
