Abstract
An abrading device for abrading a floor structure comprises a first abrading assembly and a second abrading assembly. The first and second abrading assemblies each have a rotationally driven contact roll provided with a sleeve having a plurality of cutouts formed in a pattern thereon. An abrading belt is trained over the sleeve. A first oscillation assembly is connected to the first abrading assembly and oscillates the contact roll of the first abrading assembly in a first direction via a linear, reciprocating motion. A second oscillation assembly is connected to the second abrading assembly and oscillates the contact roll of the second abrading assembly in a second direction via a linear reciprocating motion. The first and second abrading assemblies consecutively abrade a top surface of the floor structure with the pattern formed by the cutouts on the respective sleeves to form a distressed visible pattern thereon.
