Abstract
The invention is a machine having a reciprocating carriage for abrading both sides of a flat article which is transmitted to the carriage through a series of pinch rollers. The carriage carries an abrading tool with floating abrading surfaces such that the flat articles can pass between the surfaces, yet remain in contact with them. Spring tension keeps the abrading surfaces in contact with flat articles to be abraded.
