ABSTRACT:
A method and apparatus for modifying the surface texture of pre-cast building blocks including a pressure-applying device so positioned as to selectively engage blocks and being adapted to apply a pressure on the surface of blocks so as to modify their texture thereof prior to the curing of the blocks. Also disclosed is an apparatus for modifying the surface texture of pre-cast building blocks including mechanisms and structures adapted to provide a plurality of longitudinal movements and a plurality of rotational movements to adjust the direction of the wearing tool in respect to the alignment of the blocks when modifying the surface texture of these blocks as well as a block-stabilizing device for stabilizing blocks during surface-texture modification operations.
