  • Belt edge burnishing machine
    Patent number: 5941101
    Abstract: A belt edge burnishing machine for burnishing the edges of a plurality of belts simultaneously. The belt edge burnishing machine comprises a conveyor and at least one buffing wheel positioned above the conveyor which is rotated about an axis parallel to the ground and to the conveyor. The belts are stacked on an edges finish board with the unfinished edges facing up. The edge finish board is placed on the conveyor which conveys the plurality of belts through the burnishing machine. As the belts pass beneath the rotating buffing wheel, the buffing wheel contacts all of the exposed unfinished edges, thus buffing the edges smooth.
