Abstract

An apparatus for removing dust released, for instance, during the production of a soft crepe paper web (1) which is creped off a Yankee cylinder (2) and spread laterally comprises a dust suction box (18) consisting of a housing (20) with an inner suction chamber (21), said housing (20) having a first inlet (24) in the form of a suction gap, a main part (25) and first and second parts (26, 27) which define said suction gap (24) between them. According to the invention the main part is in the form of part of a cylinder to provide a corresponding curved inner side (34) in the suction chamber, and the suction gap comprises an outer gradual throttling (29) and an inner gradual enlargement (30), said throttling and enlargement merging at a transition (31) where said throttling is maximal. The first inlet forming part (26) comprises a flat surface (33) that defines its side of said enlargement whereas the second part (27) forming the inlet comprises both a curved surface (36) having predetermined radius and such an arc length that it defines the whole of its side of the throttling (29) and an initial part of the enlargement (30), and also an inner, flat surface (37) extending at a tangent from the curved surface (36) and forming an acute angle alpha with a tangent to the curved surface at said transition.
