ABSTRACT:
Green brick newly formed by pushing a slug through a wire cutter, have their longitudinal edges shaped by means of a plurality of rollers positioned above and across the path of conveyance of the bricks so that each roller simultaneously engages the adjacent edges of two adjacent bricks. The shape imparted to the brick edges is governed by the shape of the peripheral portions of the rollers. The rollers are mounted on a shaft at fixed locations along the shaft in alignment with the wires of the wire cutter. Before operation the locations of the rollers along the shaft may be adjusted through spacers in order to adapt the rollers to different sizes of bricks. The roller mounting shaft may be adjusted in a vertical plane towards or away from the conveyor path to adjust the depth of the rollers for a specific operation or to sufficiently raise the rollers away from the conveyor path where they may be kept idle when not in use. The shaping of the edges of the bricks causes brick material to adhere between adjacent bricks immediately below the edges which have been shaped. Accordingly, a plurality of cutter members are provided across the path of conveyance to enter between the rows of bricks to sever the adhering material between the bricks. The cutter members are mounted on individual arms which, in turn, are mounted on a cross member overlying said path such that the arms are movable transversely of the path. The cross member is adjustable in a vertical plane towards and away from the conveyor path to adjust the depth of the cutting member for a specific operation or to merely place them in an idle position when not in use.
