  • Method to create irregular edge decorative blocks
    Patent number: 6979418
    Abstract: A method to create blocks having a weathered and aged look by modifying the blocks before they are cured. Green blocks exiting a block forming machine are conveyed along a path past brush elements which scrub block mix from the upper longitudinal corners of the formed, uncured blocks. The blocks are also passed longitudinally over tooth elements which irregularly remove block mix from the lower longitudinal corners of the green blocks. The modified green blocks are moved to a kiln for curing.
