1. An abrading device for providing a distressed visible pattern on a top surface of a floor structure, comprising:
a first abrading assembly and a second abrading assembly, the first and second abrading assemblies each having a rotationally driven contact roll and an idler roll, the contact roll being provided with a sleeve having a plurality of cutouts formed in a pattern thereon, and an abrading belt comprising an abrasive material trained over the sleeve of the contact roll and idler roll; a first oscillation assembly connected to the first abrading assembly that oscillates the contact roll of the first abrading assembly in a first direction via a linear reciprocating motion; and a second oscillation assembly connected to the second abrading assembly that oscillates the contact roll of the second abrading assembly in a second direction via a linear reciprocating motion, wherein the second direction is different than the first direction; wherein the contact roll of the second abrading assembly is configured and operable to form an intermittent distressed visible pattern on the floor structure; and wherein the first and second oscillation assemblies are configured to operate independently so as to oscillate the contact roll of the first abrading assembly in the first direction while oscillating the contact roll of the second abrading assembly in the second direction respectively. |
