ABSTRACT:
Disclosed are apparatus and methods for forming rounded and textured edges along lengthwise extending faces of new brick to simulate old brick. The apparatus includes an elongated support having a transversely extending conveyor adjacent one end for receiving brick slugs. The slugs are successively pushed onto the support and through a cutter to form bricks. First and second transverse rows of inclined ramps are spaced longitudinally one from the other along the support with adjacent ramps in each transverse row spaced one from the other a distance in excess of the width of a brick. The ramps of the first and second rows are transversely offset one from the other a full brick width. When a transverse row of bricks is displaced longitudinally along the support through the first row of ramps, alternate bricks are elevated and inclined by the ramps into engagement with a first set of weighted rollers. The rollers impress the desired rounded and textured configuration into and along the opposite edges of the lengthwise extending faces of the elevated alternate bricks whereupon the elevated bricks return to a common plane with the unedged and unelevated bricks. When the row of brick is displaced through the second row of ramps, the alternate unedged bricks are elevated and inclined into engagement with a second set of weighted rollers which similarly round and texture the opposite edges of the lengthwise extending faces of the previously unedged bricks.
