Abstract
Apparatus and method for more uniformly blending a layered stack of bricks having a central core section of lesser hardness and lighter color than in a surrounding outer shell section. The bricks are first unloaded from a hack into layers which include a corresponding core section and surrounding shell section. Thereafter, the bricks in each alternate layer are rearranged by placing bricks from the normally occurring core section areas into the normally occurring shell section areas and vice versa. Then the layers of bricks (both rearranged and unaltered) are restacked. The resulting stack will be blended such that when each "slice" of the stack is strapped into a packaged group of bricks, the resulting packaged groups will have approximately equal numbers of bricks having differing degrees of hardness and color.
