A method for cleaning a web by removing dust and other particles therefrom in which a blowing is directed at a web to cause the separation of dust from the web and a suction effect is applied to the web to remove the dust separated from the web. A vortex flow may be produced before the dust separating blowing in the running direction of the web to prevent carriage of the dust into the environment and to compensate for the suction effect on the runnability of the web.

Method for cleaning a web

A device in a paper machine or in a finishing device of a paper machine for removing dust in which a blowing is directed at a web to cause the separation of dust from the web and a suction effect is applied to the web to remove the dust separated from the web. A vortex flow is produced before the dust separating blowing in the running direction of the web to prevent carriage of the dust into the environment and to compensate for the suction effect on the runnability of the web. In the device, blow elements produce a blowing that separates dust from the web and suction elements produce a suction effect so as to remove the dust that is separated out of connection with the web. The device includes an arrangement for producing a vortex flow before the dust separation blowing in the running direction of the web to prevent carriage of the dust into the environment and to compensate for the suction effect.

Device in a paper machine or in a finishing device of a paper machine

A method and system for air-conditioning of a coating station for a paper web in which hot and moist air is removed from the environment of the coating station. In the method, a dry and cool air flow is blown into a working area of a person working at the coating station, to the direct vicinity of the person, so as to air-condition the working area and to constitute breathing air for the person. Out of the working area of the person, from the direct vicinity of the person, hot and moist air is removed as a suction flow. The system for air-conditioning of a coating station for a paper web or equivalent is placed in connection with the coating station and includes an exhaust air device. The air-conditioning system is placed in connection with the frame constructions of the coating station and includes a blow device for producing an air flow so as to air-condition the working area of the person working at the coating station and to constitute breathing air for the person as well as at least one suction device for removing hot and moist air out of the working area of the person.
