ABSTRACT:
A machine for extruding hollow cored concrete sections, wherein concrete forced into a travelling mold by augers and trailing mandrels form a cored concrete slab, wherein the mold is provided with a vibrating top plate assembly having forward and trailing sections, the forward section having a greater amplitude of vibration than the trailing section so as to minimize amplitude to vibration transferred to the concrete in the afterpart of the mold.
