Method and apparatus for extracting dust that is released when creping off a paper web

摘要: In a tissue paper machine, the dust that is released when web creped off Yankee dryer (3) constitutes major work environment problem. To provide an improved extraction of and thereby improve for operating personnel involved, extractor (25") having internal space (39") stabilizing, imperforate plane (37") mounted immediately adjacent to intended path travel (1) so during its transportation will place itself in fixed position close (37"), and, at least essential part entrained boundary layer containing air eliminated through suction only, (39"). The carried out rear and/or front edge (25), suitably both on overside underside (1). Dust does not become layers be sucked away by one box (55) sloping cover (57), under spaced therefrom doctor beam (11). Preferably, stream, which sufficient force carry caused suction, made rise towards between (27) downstream latter.
