A dust removal device provided with a discharge outlet 30a (30) and suction inlet 21a, 21b, 22a, 22b facing the surface of an object to be dedusted 100 undergoing relative movement and arranged at a predetermined interval along the direction of relative movement of the object to be dedusted 100 and that discharges gas from the discharge outlet 30 to the surface of the object to be dedusted 10 while drawing in the gas above the surface of the object to be dedusted 100 through the suction inlet 21a, 21b, 22a, 22b. The dust removal device has a gas discharge path 32b with a shape that gradually expands from an opening 33 facing the object to be dedusted 100 to the discharge outlet 30a.

A glass manufacturing apparatus includes a first nozzle including a first orifice facing a travel path. The glass manufacturing apparatus includes a gas source in fluid communication with the first nozzle, with the gas source directing a gas flow to the first nozzle. The glass manufacturing apparatus includes a controller coupled to one or more of the gas source or the first nozzle to vary the gas flow from the gas source the first nozzle such that the first nozzle is discharges a series of gas bursts through the first orifice toward the travel path at a frequency within a range from about 10 Hz to about 45 Hz. A second nozzle is spaced apart from the first nozzle. The second nozzle includes a second orifice facing the travel path. The second nozzle discharges a continuous gas flow through the second orifice toward the travel path.

A cleaner head having a discharging slit 6 on the center and sucking slits 7 on left and right on a corresponding wall portion 15 facing a dust-removed face 10, and, outer extended lines L.sub.7 of the pair of sucking slits 7 are inclined as to mutually come close and intersect as departed from the corresponding wall portion 15.

A cleaning head is disclosed for use in a traversing shower system. The cleaning head includes a plurality of directional fluid nozzles for discharging a fluid, each of which is provided along a different direction toward a work surface such that no two directions cross one another between the cleaning head and a working surface.

A system for suctioning dust and fibrils from a moving web comprising: a suction system; a suction manifold being connected to the suction system; the manifold comprising at least one suction nozzle; the manifold being arranged crossways to the moving web; characterized by the fact that the manifold includes a device for adjusting the distance between the at least one suction nozzle and the web; a roller opposed to the at least one suction nozzle on which the web is made to run.

An apparatus for cleaning a felt in a system for producing a paper web has a device for introducing a cleaning liquid into the felt and at least one following suction device in the direction of movement of the felt and having a vacuum duct, through which the cleaning liquid is suctioned out of the felt. The suction device between the vacuum duct and the felt is formed with suction ducts, through which the cleaning liquid in the felt is suctioned away. At least one of the suction ducts is assigned an inflatable valve element. In the inflated state of the valve element the suction duct is closed and in its ventilated state the suction duct is opened.

A web conveyance apparatus (101) may comprise a first cleaning device (136) with a first exterior suction port (211) laterally positioned outside of a first edge (201a) and facing a footprint (204a) of a first major surface (203a) of a web (103). In further embodiments, a method of manufacturing a web (103) may comprise conveying the web along a direction of a conveyance path and suctioning particles from the first major surface (203a) with a first exterior suction port (211) laterally positioned outside of a first edge (201a) and facing a footprint (204a) of a first major surface (203a) while conveying the web.

A method and apparatus for removing particles, such as dust, generated by a moving web is disclosed. A dust control platform is positioned adjacent to a traversing web to catch the particles generated by the web. The particles pass through one or more apertures defined by an accumulation surface. The particles pass through the accumulation surface and into an accumulation chamber. The accumulation chamber may include a sweeping device or other device that may be used to transfer the accumulated particles to a collection chamber. The collection chamber is connected to a vacuum source. Vacuum is applied to the collection chamber by the vacuum source such that the particles are removed from the collection chamber.

A vacuum system is configured to segregate debris on a conveyor belt. The vacuum system includes a manifold further comprising a manifold body joined to a first end wing and a second end wing. The manifold body further includes a tube slot opening joined to a tube slot. A vacuum tube adapter is joined to the tube slot. A vacuum tube adapter flared portion is arranged on the vacuum tube adapter. The vacuum tube adapter flared portion is adapted to receive a flexible vacuum intake hose. A first end flap further includes a first end flap central opening, and joined the first end wing. A second end flap further includes a second end flap central opening, and joined the second end wing.
