ABSTRACT:
The present invention is directed to introducing air into a web interface of a former board without using holes or internal passageways in the forming bar. Exemplary embodiments achieve an even distribution of air on a surface of the former board which allows a minimum air gap to be achieved between the former board surface and the moving web. As such, damage to the moving web, and wear of the former board are reduced and/or eliminated. Therefore, the former board can be used to introduce a fold into the web without creating significant contact between the former board and the web.
