ABSTRACT:
An apparatus for cleaning particles from a web is disclosed. An air flow is directed against the web through a pressure slit whereupon the air flow is deflected and guided along the web to two suction slits. The air flow is directed against the web by means of an nozzle in the shape of two expanding blades, which each are ended in an edge. Also the suction slits are surrounded by two blades and another two blades prevent the inlet of surrounding air. Each slit opens into a chamber, which each comprises an air distribution tube provided with rows of holes which are so adapted that the volume flow per length unit of the distribution tube of the slit will be essentially constant.
