Abstract: A dust hood for a papermaking system. The hood body has a roof and depending long sidewalls. An inlet extends substantially the entirety of each of the long sidewalls. The hood includes an outlet at one end. The roof is peaked and reaches a peak line. The hood may be positioned at or near floor level and used with air ramps that drive dust toward the inlets.

Abstract: A below-web dust hood for a papermaking system. The hood body has the general shape of a tapering trapezoidal pyramid, taller at one end than the other. The inlet of the hood body tapers inversely in height—broader where the hood body is shorter, and narrower where the hood body is taller in order to maintain uniform flow across the entire inlet.

Abstract: An upper reel hood in dust control system for the “dry” side of a through-air drying (TAD) papermaking system. The hood body has the general shape of a tapering trapezoidal pyramid, taller at one end than the other. The inlet of the hood body tapers inversely in height—broader where the hood body is shorter, and narrower where the hood body is taller in order to maintain uniform flow across the entire inlet. The hood body may be over 5 meters wide.

Abstract: One aspect of the invention relates to a dust control system for the “dry” side of a through-air drying (TAD) papermaking system. A series of dust hoods are placed in specific locations, both above and below the web of paper or tissue that is being manufactured. Each hood spans at least a substantial portion of the width of the belt or web, and each hood is shaped and otherwise adapted for its particular position, both to accommodate the structure of the papermaking machine and to ensure that the airflow through the inlet of the hood is substantially uniform across its entire width. Baffles are provided between certain hoods in order to create dust-control zones around the hoods, and air ramps and other elements may be used to drive dust into the dust control zones and toward the hoods.
