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.
Claims9
Apparatus for the production of a single face coated corrugated pasteboard formed of a first web of material having two faces, and of a smooth covering web of material comprising:
- a corrugated cylinder having teeth on its exterior for corrugating the first web of material;
- a glue means adjacent the corrugator cylinder for applying glue to one face of the corrugated first web;
- drying means adjacent the glue means and opposite the corrugator cylinder for drying the glue applied to the corrugated first web;
- a corrugator counter-element cooperating with the corrugator cylinder to at least carry the corrugated web, the counter-element being an endless, longitudinally extending, toothed belt engaging over at least part of the circumference of said corrugator cylinder and said counter-element extending above said glue means and drying means to support the corrugated web of material thereover;
- guide means arranged above said glue means and drying means for guiding said counter-element above said glue means and drying means;
- and
- means for engaging the smooth covering web of material against the one face of the corrugated first web prior to the corrugated first web entering the drying means.
