Abstract
A roller wall guard system for use on a surface-finishing machine having a circular guard ring of a given circumference made up of a pair of wall guards. Each wall guard has an arc shaped arm having a first end attached to a roller and extending along a length to a second end also having a roller. Each arm is pivotally connected to the surface-finishing machine at an intermediate location between the first and second ends, so that the arm pivots within a controlled arc. The length of the arms and the diameters of the rollers are configured to define a line between a point of rolling engagement of the first roller against a second surface and a point of rolling engagement of the second roller against the second surface. The line lies outside of the circumference of the guard ring. When a first roller contacts a second surface, the arm pivots about the attachment so that the second roller contacts the second surface and the surface-finishing machine is directed in a line of travel parallel to the second surface.
