Abstract: A wire-cutting apparatus 10 used in the manufacture of bricks. The apparatus includes a pair of spaced generally parallel coextensive beams 13 and 14 between which cutting wires 15 pass. Associated with each wire 15 are groove-forming blades 27 and 28.

Abstract: An apparatus for making green bricks having the appearance of tumbled brick achieves these results by deforming a slug from which green bricks are made. The slug is deformed by the use of a reciprocating member that alternately retracts and then hits (deforms) the slug. By varying the angle of attack (between the deformation member and the slug), the degree of travel of the deformation member, and the orientation of deformation blades on the deformation member, the green bricks have a deformation pattern that appears fairly random as if they had been tumbled.

Abstract: A support system (40) to support a plurality of bricks (42) which in combination with mortar (50) forms a wall. The support system (40) includes a sheet (43) provided with a plurality of generally parallel transversely spaced ribs (45), which ribs (45) are plastically deformed to provide a plurality of longitudinally spaced peaks (50 & 51). The bricks or tiles (42) are engaged between opposing peaks (50 & 51) to be retained in position thereby until the mortar (50) sets.
