  • Patent number: 4064658
    Abstract: A brush roundator comprises an endless conveyor for conveying brushes along a straight path in one direction. The brushes are mounted to the conveyor with their bristles extending outwardly away from the conveyor. A plurality of abrasion disc series, or groups, each including a plurality of abrasion discs arranged side-by-side in a line are positioned parallel to the conveyor and in the paths of the outer tips of the bristles. Each of the disc series is mounted on a frame whose position can be adjusted independently of the frames of the other series, both angularly and/or linearly. Each disc series includes a motor mounted on the frame to drive a first abrasion disc of the series and that disc has a gear thereon which meshes with a gear of an adjacent abrasion disc to rotate it in the opposite direction. This gear is linked to a gear of a next adjacent abrasion disc in a similar manner to rotate it in an opposite direction and so on.
