ABSTRACT:
A machine for the manufacturing of moulded articles of plastic material, in particular of helmets for motor cyclists, includes at least two moulds and at least a counter-mould for the forming of the articles, the moulds and counter-mould(s) defining between themselves moulding cavities of different shapes. The moulds and the counter-moulds, excepting the first one, are each connected with a feeder of a different plastic material, and the moulds can be moved into alignment with the counter-moulds, for the moulding of respective superimposed layers of different plastic materials by sintering with steam.
One mould is suitable to be positioned in correspondence of a zone of unloading of the article produced while at least another mould is in its forming position.
