摘要： A method and device for intensifying the operation of a Yankee press in a soft-tissue machine in which a web is pressed in one or several nips formed between a Yankee cylinder and one or more press rolls. The web is dried on the Yankee cylinder by blowing hot air introduced through the Yankee hood against the web. In the method, a blow device is used to blow hot and humid air against the web. The blow air for the blow device is taken from the outlet/heat recovery of the air system of the Yankee hood, and the exhaust air from the blow device is returned to the outlet/heat recovery of the air system of the Yankee hood. Air is blown against the web at the proximity of the nip formed between the Yankee cylinder and the first press roll, before and near the first press nip, in the running direction of the web. The blow device includes a blow chamber, an exhaust chamber, and blow nozzles for blowing hot and humid air against the web and exhaust-air ducts for the removal of the air.

摘要： 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.
