US Patent 8342773 Paving apparatus

A paving apparatus is arranged to pave a supporting surface by casting individual paving stones on site on a mobile frame and placing the cast paving stones directly onto the supporting surface in an uncured state adjacent previously placed paving stones as the apparatus is displaced along the supporting surface. Molds are supported by a conveying mechanism of the paving apparatus for movement between a casting position in alignment with a hopper dispensing castable material into the molds and a placing position in which the uncured paving stones are dispensed from the mold directly onto the supporting surface to be paved.
