ABSTRACT:
The apparatus has a plurality of open-ended female dies with a movable lower male die positioned in the lower end of each one. A supply box is shiftable over the female dies to deposit concrete therein, following which a plurality of upper male dies are moved down into the female dies to compact the concrete therein into chairs. Wire supply means feeds wires through the upper male dies and into the concrete in the female dies before the concrete is compacted. After the wires have been cut above the female dies, the upper male dies are retracted and the lower male dies are moved upwardly to eject the compacted chairs from the female dies.
