ABSTRACT:
Apparatus for continuously forming concrete blocks or pavers comprises a frame for defining a supporting structure with a mold box flexibly mounted thereon, the mold box having internal cavities contoured to define preselected block patterns, wherein a feed device for receiving concrete material is operable for selective positioning over an upper surface of the mold box for investing concrete material into the cavities. First and second sets of vibrators are mounted, respectively, generally at opposite ends of the mold box means and are operable for being selectively driven by associated first and second power drives. The first and second power drives are selectively operable for synchronizing or independently actuated the first and second sets of vibrators, respectively, so that concrete material invested into the cavities of the mold box may be vibrated so that the concrete material is evenly distributed in substantially equal masses throughout the cavities in the mold box.
