Abstract: An apparatus for breaking the flutes from fluted blocks. The apparatus includes breaker head means for engaging opposite surfaces of a block flute and means for rotating the breaker head means to apply rotational forces which break the flute from the block forming decorative surfaces. In order to facilitate the engagement of the fluted blocks with the breaker head an infeed conveyor and block positioning means are provided to move the flutes of fluted blocks into engagement with the breaker head means and to withdraw the block after the flutes have been broken off. Further means are provided to propel the block to a discharge conveyor from which the blocks may be removed and stacked for shipment.
