ABSTRACT:
A method in a paper machine or in a finishing device of a paper machine for collecting and removing dust and other particulate material separated from or in the vicinity of a web. Air that contains the dust is transferred by air blowings, specifically, a first air flow is directed from a first blow nozzle to flow in the cross direction of the machine from the tending side of the machine to the driving side. This first air flow carries the dust separated from the web or equivalent along with it. The dust-laden air flow is turned downwards by a second air flow being directed from a second blow nozzle to be drawn into a suction box.
