ABSTRACT:
A machine for manufacturing concrete building blocks faced with a decorative material is provided with a mold having a wall which is removable to expose a face of a freshly cast block. The material is arranged on a horizontal panel alongside the block and this panel is pivoted into a vertical position to apply the material to the exposed face of the upright block. A clamping and vibrating action is applied to the panel to further embed the material in the vertical face.
