Abstract: A method and apparatus for controlling dust on paper machinery and the like is shown. A foil, a baffle and an exhaust are used to direct contaminated air away from the machinery and the sheet or web of material running through the machinery. Thus the deleterious effect of the contaminants is minimized and contained.
Abstract: A self-cleaning paper trap for use within a dust control system and mounted in the duct to trap sheet materials. The paper trap includes a housing which carries a plurality of spaced grid bars to trap the sheet materials and a wiper bar which is vertically reciprocal relative to the grid bars to wipe trapped sheet materials from the bars. An automatic cable control apparatus is operatively engaged with the wiper bar to permit remote wiper bar actuation without the need for system shut-down.
