Abstract (en)
A machine for producing blocks or elements includes a base board 13 which defines a surface to close the lower end of a mould box 12. Extending into the upper end of the mould box is a frame 14 forming part of or secured to a throat portion 11 which depends from a hopper 10. Means not shown is provided to raise the mould box following compaction of the material in the throat portion and mould box, above the lower end of the frame 14, to eject the compacted material from the box. Further means is provided to raise the throat portion and frame by a limited amount to cause fracture of the compacted mass of material in a plane generally defined by the frame. The plug of compacted material in the frame and throat portion until vibrated, prevents material in the hopper from falling through the throat portion.
