DEVICE FOR PRODUCING AND/OR TREATING A FIBROUS WEB WITH A DUST REMOVAL SYSTEM

摘要

The invention relates to a device (6) for producing and/or treating a fibrous web, which device (6) is characterized by an extent in a width direction (CD) and a longitudinal direction (MD) as viewed in the run-through direction of the fibrous web, with a dust removal system (1) which can be arranged spaced apart from the fibrous web along at least one part region of a web-guiding path of the fibrous web, which web-guiding path is defined by a width direction and a guide direction for the fibrous web, comprising at least one surface (3) which can be arranged above the web-guiding path, points away from the web-guiding path and is assigned means for cleaning. The invention is characterized in that the surface (3) is configured such that it is fluid-tight and, with the formation of a tilted plane with an upper end region (18) and a lower end region (19), is inclined or can be inclined transversely with respect to the longitudinal direction of the device and/or at an angle with respect to the longitudinal direction (MD) of the device, and the means for cleaning comprise means for applying a fluid onto the surface (3) downwards in the inclination direction.
