Abstract

An apparatus for treating the edges of pre-fired brick includes an extruder for extruding a column of clay and a wire cutter assembly for severing the column into individual bricks having their longitudinal axes substantially perpendicular to the direction of extrusion. The bricks are transported to a first conveyor where they are turned and directed to a side conveyor. As the pre-fired bricks move on the side conveyor, they move in a single file arrangement with their longitudinal axes substantially parallel to the direction of movement. The upper longitudinal edges of the pre-fired brick are treated by engagement with a pair of canted rollers to give the edges of the brick an irregular appearance. The bricks are then reoriented by a pair of rotating tables which direct the bricks onto a third conveyor with the axes of the brick being substantially perpendicular to their direction of travel.
