  • Apparatus for forming irregular shaped brick
    Patent number: 4108586
    Abstract: A horizontal brick feed conveyor continuously feeds green undried moist clay bricks along a path beneath a lower horizontal flight of an elastic hold-down belt member mounted above and moving in the same direction as the conveyor to engage the upper surface of the conveyed brick; a relatively large motor-driven irregularly spaced impression roller is adjustably mounted adjacent the upper surface of the horizontal flight of the hold-down belt to engage the horizontal flight so that a number of protrusions on the roller deflect portions of the elastic hold-down belt downwardly into the green brick immediately beneath the hold-down belt so that the bricks are distorted and misshaped to give an antique or handmade effect.
