ABSTRACT:
A treatment medium, such as cooling air, is blown onto the surface of a web moving in a longitudinal direction, with the aid of at least one longitudinal blowing box or so-called nozzle finger extending across the web and having at least one blowing nozzle facing the web. The blowing box is longitudinally separated by a divider wall forming at least a longitudinal nozzle chamber and at least one overflow chamber. Both channels receive treatment medium at the same end of the box. The divider wall has at least one opening through which the two channels communicated with each other at the opposite end of the box. This feature assures a treatment medium distribution in the channel facing the web, as if treatment medium were supplied into the blowing box at both ends. The box may also be divided into two nozzle channels and two overflow channels, whereby two divider walls may extend substantially vertically to form two overflow channels each having a triangular cross-section.
