ABSTRACT:
Molds and processes that permit high-speed, mass production of retaining wall blocks having patterned or other processed front faces, as well as retaining wall blocks formed by such processes. The invention permits the front face of the block to be impressed with a pattern or otherwise directly processed, to allow the formation of pre-determined block front faces, while at the same time facilitating high-speed, high-volume production of blocks. A mirror image of the desired pattern can be created on a stripper shoe by selecting a desired three-dimensional surface from a naturally occurring or man made object and digitally scanning the selected three-dimensional pattern to create scanned data. The scanned data can then be used to machine a face of the stripper shoe that is the mirror image of the selected pattern.
