A block texture-modifying apparatus (128) for modifying the surface texture of blocks. The apparatus (128) comprises a block support (12'), a block-texture-modifying assembly (130) and a translational movement assembly (132). The block support (12') supports the blocks thereon. The block-texture-modifying assembly (130) engages the blocks on the support (12'). The translational movement assembly (132) provides a translational movement between the blocks on the support (12') and the block-texture-modifying assembly (130). The block-texture-modifying assembly (130) acts on the blocks it engaged during this translational movement in order to modify their respective surface texture. |
