ABSTRACT:
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.
