ABSTRACT:
A texturing assembly for a machine for forming special brick shapes from extruded slugs of unfired material. The slugs are conveyed forward by conveyor(s) onto an elevator which lifts vertically. This lift pushes the slugs into opposing rollers. The rollers are arranged on opposing shafts spaced to produce vertical indentations in the slugs on 8-inch centers. The edges shaped by the rollers are the 4-inch long textured edges on the finished faces. At a convenient height above the rollers and on matching 8-inch centers are fixed horizontal wires. The cuts by the wires are centered in the indentations made by the opposing rollers. The cut and textured green paver brick rest on top of the slugs captive in the opposing rollers until lifted away by an automatic setting machine.
