Abstract
A device to remove surface particulates from fed materials, as paper and the like, wherein a reduced pressure is applied in a housing to effect a pressure gradient across the fed material to distort and conform the same to a substantial peripheral portion of a brush rotating in the housing to provide an area of surface cleaning engagement between the brush and the fed material to thereby produce an effective and efficient cleaning action.
Claims17
A device to clean a moving surface comprising:
- a housing beneath which the surface moves in spaced relation,
- cleaning means rotatable in said housing relative to the moving surface to contact and clean the same,
- skirt means on said housing and extending therefrom to engage and wipe the surface moving therebeneath before and after the same is cleaned by said cleaning means,
- ion discharge means operable to deposit the discharge thereof on the moving surfce at least before the same is engaged by said skirt means,
- and vacuum means coupled to said housing whereby on application thereof, the moving surface is drawn into said housing against said cleaning means causing the moving surface to distort along a substantial perimetric portion of and about said cleaning means to provide an increased period of a cleaning engagement between the moving surface and said cleaning means as said skirt means retains the moving surface spaced from said housing and the ambient environment so that material dislodged from the moving surface is collected in said vacuum means.

In combination, a housing,
- brush means rotatable journalled in said housing and operable to contact a material moving in path relative thereto for cleaning thereby,
- a pair of flexible porous means carried on said housing in spaced relation to and fore and aft of said brush means to wipe the moving material before and after the same is cleaned by said brush means,
- corona discharge means operable to deposit electrical ions on the moving material at least before the same contacts said brush means,
- and vacuum source means in communication with said housing to draw the material out of its path of movement into arcuate contact with and part way about a substantial perimetric portion of said rotating brush means to increase the period of contact of said brush means with the moving material to clean the surface thereof in a negative pressure environment of said vacuum source partially isolated from ambient air pressure by said porous means.
1 more element
A device for cleaning a moving surface comprising:
- a housing extending for the width of the moving surface,
- a cleaner rotatable in said housing in a direction opposite the direction of the moving surface and defining spaced anterior and posterior cleaning zones on opposite sides thereof in said housing and extending for the width of the moving surface,
- means connected with said housing to subject the zones, cleaner and moving surface to a negative pressure,
- skirt means on said housing spaced fore and aft of said cleaner and defining the outer limits of said zones such that as the surface moves beneath said housing it is subjected to the negative pressure and is drawn into said zones and is thereby caused to conform about and into area cleaning engagement with said rotary cleaner,
- and means on said housing to apply a stream of ions to the moving surface prior to subjecting the same to said negative pressure.
