ABSTRACT:
Method and apparatus for forming and laying paving blocks in which interchangeable grids are provided of dissimilar configuration comprising a plurality of mould cavities each enclosing one or more fixed centers of the modules of the pattern, whatever is in the conformation of the said grids. The modular and transformable ramming assembly comprises a plurality of fixed securing points distributed to correspond to the fixed centers of the modules of the mould pattern and intended for the removable fitting of ramming plates of forms and dimensions analogous with those of the underlying cavities of the selected grid. The changing of forms and/or dimensions of the moulded paving stones or slabs is effected by replacing one grid by another differently conformed grid and by fixing new removable ramming plates corresponding to the forms and/or dimensions of the cavities of the new grid, by means of the said fixing points.
