ABSTRACT:
Production line apparatus for producing concrete floors. A table for supporting a concrete receiving mold is movably mounted atop a frame. Shaking means connected to and between the frame and the table shake the table settling the concrete within the mold. A pair of conveyors extend from the table to convey the mold from the table. The conveyors extend over the table but beneath the mold supporting surfaces provided on the table. The conveyors are lifted upward against the mold lifting the mold from the table. A mold turning over device is positioned at one end of the conveyors and is operable to receive the mold and to turn the mold upside-down repositioning the mold atop a second pair of conveyors. A hoist extends over the second pair of conveyors and is operable to lift the mold upwardly leaving the solidified concrete floor atop the second pair of conveyors. The mold is lifted and positioned between a pair of spaced apart return conveyors which extend back toward the shaker table. The return conveyors twist about a return axis until the mold is repositioned right-side-up.
