Abstract
An apparatus for removing surface irregularities from a flat workpiece includes one or more abrading assemblies through which the workpiece passes sequentially. Each abrading assembly has a lower contact assembly and an upper contact assembly. The upper contact assembly is precisely spaced above the lower contact assembly in opposing parallel relation to the lower assembly. The lower and upper contact assemblies reciprocate in opposing directions to provide abrading action to the workpiece.
