Abstract
A surface finishing apparatus for finishing the edge surfaces of fiberboards or like substrates. A pair of axially convergent drive wheels impart rotational and radial motion to a board and pushes the board against a foiling head or other surface finishing hardware. The foiling wheel is pushed by a pneumatic cylinder towards the board. An air clamp holds the board down against the drive wheels during operation. A speed indexer computer controls the rotation of the axially convergent drive wheels in inverse relationship to the rotational speed of the foiling head. In an alternative embodiment, a pair of angled hold-down wheels are used to hold the board against the drive wheels.
Claims4
A drive assembly for use with a surface finishing machine, said drive assembly comprising:
- (a) a pair of axially convergent drive wheels, each said drive wheel having a rotational axis, each said drive wheel having a drive contact area that is beveled in relation to the rotational axis of the drive wheel;
- (b) means for imparting rotational power to said pair of drive wheels;
- and
- (c) means for adjusting the point of convergence of the rotational axes of said pair of axially convergent drive wheels;
- (d) wherein each said drive wheel is configured to provide a circular driving force to an object placed in contact with said drive wheel's drive contact area.
