  • Rotary brush sheet deceleration device
    Patent number: 6145833
    Abstract: A rotary bristle brush, particularly adapted for use in a decelerating conveyor for shingling sheets, operates over a preload surface that subjects the moving bristles to an increasing bending deflection. The bristles are released from the preload surface just above the sheets entering the shingling conveyor to allow the ends of the preloaded bristles to spring downwardly into contact with the sheet. The contact force of the bristles helps drive the sheet downwardly onto the shingling conveyor which may be a vacuum conveyor.

  • Sheet deceleration device using pultruded bristle brushes
    Patent number: 5992844
    Abstract: The bristles for brushes used in the deceleration section of a sheet handling system are made of a pultruded construction utilizing a high strength fiber core and high wear resin binder to provide bristles which will not acquire a set from bending and exhibit extremely long wear life. Pultruded fibers of various cross sectional shapes and constructions may be utilized to tune the brushes to a particular sheet handling application.
