ABSTRACT:
An apparatus and method for dressing marginal areas of externally viewable surfaces of a building block. The apparatus includes at least one chipper having rotational axis and a plurality of outwardly extending teeth randomly disposed thereabout. The chipper is positioned and oriented so that its teeth may effectively work a predetermined marginal area of interest. As the predetermined marginal area of interest and the teeth of the chipper are brought into contact with each other, portions of the marginal area are randomly impacted and fractured to form an erose or jagged surface that resembles hand dressing. The apparatus may also include additional chippers, each having a rotational axis and a plurality of teeth randomly disposed thereabout.
