Abstract (en)
[origin: WO9220502A1] Method and device for manufacturing a construction block by pressure moulding a mixture of a hydraulic binder such as plaster, an inert filler such as sand, and water, involving passing a mould (50) through different work stations including a station (A) for filling the mould with a measured quantity of the mixture (56), a station (B) for fitting a top plate (38) on the mould, a station (C) for compressing the mixture in the mould, a station (D) for holding the top and bottom plates (38, 40) in place in the mould, a station (E) for removing the top plate (38), and a release station (F).
