Abstract (en)
[origin: EP0909622A1] The device comprises a loading carriage (10) having at least one loading compartment (11) with plan dimensions equal to those of a mould cavity (6) and being driven with reciprocating movement between a retracted position in which the loading compartment (11) receives the material, and an advanced position in which the loading compartment (11) releases the material into the mould cavity (6). Above the compartment (11) of the carriage when in its retracted position there is positioned an intermediate container (20) having plan dimensions equal to the loading compartment (11) and with its internal space divided by a first series of vertical baffles (22) which define a plurality of shaped regions separated from each other. To the container (20) there are applied means (30', 30'', 21) for conveying, into said shaped regions, different materials specific for said regions, and means (23, 24) for closing and opening material passage through the base of the intermediate container (20). Within the carriage loading compartment (11) there is positioned a second series of vertical baffles (12), which define a plurality of mutually separated shaped regions equal in plan view to the regions defined by the first series of baffles (22). <IMAGE>
